Abstract:
In the cultural heritage field the recording and documentation of small and medium size objects with very detailed Digital Surface Models (DSM) is readily possible by through the use of high resolution and high precision triangulation laser scanners. 3D surface recording of archaeological objects can be easily achieved in museums; however, this type of record can be quite expensive. In many cases photogrammetry can provide a viable alternative for the generation of DSMs. The photogrammetric procedure has some benefits with respect to laser survey. The research described in this paper sets out to verify the reconstruction accuracy of DSMs of some archaeological artifacts obtained by photogrammetric survey. The experimentation has been carried out on some objects preserved in the Petrie Museum of Egyptian Archaeology at University College London (UCL). DSMs produced by two photogrammetric software packages are compared with the digital 3D model obtained by a state of the art triangulation color laser scanner. Intercomparison between the generated DSM has allowed an evaluation of metric accuracy of the photogrammetric approach applied to archaeological documentation and of precision performances of the two software packages.

Abstract:
Absolute orientation is a classic photogrammetric task for recovering the transformation relationship between two coordinate systems. In low-altitude photogrammetric field, arbitrary coordinate system in the network of aerial triangulation is spatial auxiliary coordinate system, which is quite different from ground photogrammetric coordinate. So the commonly used solution to absolute orientation with simplified parameters is unsuitable for low-altitude photogrammetry. In this paper, a novel solution of absolute orientation is proposed, the initial parameters of absolute orientation can be solved by the formula using centroids of coordinates instead of simplified parameters, then the parameters of absolute orientation are iteratively refined by Levenberg-Marquardt algorithm. Experimental results show that the solution is effective and practical. It may be suitable to implement absolute orientation in low-altitude photogrammetry.

Abstract:
In the modern context of digital technology in the field of surveying and mapping, the technique of digital photogrammetry plays crucial role in all steps of mapping. There are some very expensive as well as low cost and free softwares are available in the market for professional photogrammetric work stations. The image triangulation and image matching is one of the very important steps of photogrammetry for which LPS as a commercial software is available in market. There are some low cost and free software as 123D Catch and Patch Boased Multi View Stereo Softwear (PMVS) also available. So, this paper mainly deals with the accuracy as well as the performance of those software for aerial triangulation and image matching for airborne image data to substitute commercial software for photogrammetric workstations. The accuracy assessment of image orientation, points cloud as well as DSM generated from those points cloud are also performed and compared with all products of LPS as commercial software.

Abstract:
Peculiar technologies on the update of topographic map linear objects to scale 1:500–1:2000 are presented. Due to that resulted peculiarities make aerial photographs, carrying out digital aerial triangulation, renewing the topographical plan. The article deals with the submitted example of the topographic plan exhibiting the renovated railway in the city of Vilnius. The updating has been made on the aerial photograph on 1:4000 scale with the photogrammetric instrument PlaniComp P3. The objects possessing no identification in photogrammetry are measured by means of a geodetic method. The redacting varied objects in a database are drawn with AutoCadsoftware. On the basis of this work it is possible to state that for fast and exact updating of topographic plans a progressive photogrammetric method is recommended. It is advised the edition data base to be made by the same operator who made photogrammetric work. The objects are visible in an aerial photo, but no identifying photogrammetry should be applied locally. Digital, renewed data are necessary for drawing up geo information systems (GIS) of the railway, to be able to make fast decisions of urgent problems.

Abstract:
Abstract. This study aims to introduce triangulation and ToF measurement techniques used in three-dimensional modelling of cultural heritages. These measurement techniques are traditional photogrammetry, SfM approach, laser scanning and time-of-flight camera. The computer based approach to photogrammetric measurement that is named SfM creates dense point cloud data in a short time. It is low-cost and very easy to application. However traditional photogrammetry needs a huge effort for creating 3D wire-frame model. On the other hand active measurement techniques such as terrestrial laser scanner and time-of-flight camera have also been used in three-dimensional modelling for more than twenty years. Each one has specific accuracy and measurement effectiveness. The large or small structures have different characters, and require proper measurement configurations. In this study, after these methods are introduced, their superior and weak properties in cultural heritage modelling to make high accuracy, high density and labour and cost effective measurement.

For use in glaciological research, between 1982 and 1984, we succeeded in surveying and mapping the Mount Gongga Glacier, on a scale of 1:25 000, by means of a combination of terrestrial and aerial photogrammetry. This paper describes the method in detail. In the survey area, we set up an independent, triangulation network, with microwave distance measurement, and two, independent, straight-line traverses, for basic control. Control points were observed by intersection. The terrestrial, photogrammetric baselines were projected and corrected into distances on the. plane of the map. Terrestrial photography accounted for the majority of the photographs of the survey area. Surveying and mapping of planimetrie and topographic features were completed on a stereo-autograph, using plates mainly from terrestrial photogrammetry. Where these data were insufficient, they were supplemented by aerial photography, plotted on a photographic plotting instrument. Orientation points of the aerial photographs were established by terrestrial, photogrammetric analysis and located on the map by an optical, mechanical method. The practical result showed that a combination of terrestrial and aerial photogrammetry, in mapping a high, mountain, glacier area, on a large scale, is more feasible and flexible than other methods and more economical as well.

Abstract:
Unmanned Aerial Vehicles (UAVs) are still an interesting and current research topic in photogrammetry. An important issue in this area is determining the elements of exterior orientation of image data acquired at low altitudes. The article presents selected mathematical methods (TGC, TIC, TAD) of estimating elements of exterior orientation for image data obtained at low altitudes. The measurement data for the experimental test were recorded by the Unmanned Aerial Vehicle platform Trimble UX-5. In the framework of the test photogrammetric flight, the authors obtained 506 images and navigation data specifying the position and orientation of the Unmanned Aerial Vehicle. As a result of the research, it is proven possible to show the usefulness of the mathematical models (TGC, TIC, TAD) in estimation of elements of exterior orientation.

Abstract:
The integration of complementary airborne light detection and ranging (LiDAR) and photogrammetric data continues to receive attention from the relevant research communities. Such an approach requires the optimized registration of the two data types within a common coordinate reference frame and thus enables the cross-calibration of one information source against another. This research assumes airborne LiDAR as a reference dataset against which in-flight camera system calibration and validation can be performed. The novel methodology involves the production of dense photogrammetric point clouds derived using the simultaneous adjustment of GNSS/IMU data and a dense set of photogrammetric tie points. Quality of the generated photogrammetric dataset is further improved through introducing the self-calibration additional parameters in the combined adjustment. A robust least squares surface matching algorithm is then used to minimise the Euclidean distances between the two datasets. After successful matching, well distributed LiDAR-derived control points (LCPs) are automatically identified and extracted. Adjustment of the photogrammetric data is then repeated using extracted LCPs in a self-calibrating bundle adjustment. The research methodology was tested using two datasets acquired using different photogrammetric digital sensor systems, a Microsoft UltraCamX large format camera and an Applanix DSS322 medium format camera. Systematic sensitivity testing included the influence of the number and weighting of LCPs required to achieve optimised adjustment. For the UltraCamX block it was found that when the number of control points exceeded 80, the accuracy of the adjustment stabilized at c. 2 cm in all axes, regardless of point weighting. Results were also compared with those from reference calibration using surveyed ground control points in the test area, with good agreement found between the two. Similar results were obtained for the DSS322 block, with block accuracy stabilizing at 100 LCPs. Moreover, for the DSS322 camera, introducing self-calibration greatly improved the accuracy of aerial triangulation.

Abstract:
Industrial surveying and photogrammetry are being increasingly applied to the measurement of engineering objects which have typical dimensions in the range 2-100 metres. Both techniques are examples of the principle of triangulation. By applying photocrammetric concepts to surveying methods and vice-versa, a general approach is established which has a number of advantages. In particular. alternative strategies for constructing and analysing measurement networks are developed. These should help to strengthen the geometry and simplify the analysis. The primary results concern the use of non-levelled theodolites, which have applications on board floating objects, and three new suggestions for controlling and computing relative orientations in photogrammetry. These involve reciprocal observations with theodolites. the photographing of linear scales defined by three target points and employing cameras which have been levelled. As a secondary result, some consideration Is given to automation, and instrument design. It is suggested that polarimetry could be successfully applied to improve the transfer of orientation in confined situations, such as in mining. In addition, the potential use of electronic cameras as photo-theodolites is discussed.

Earth observation and analysis became feasible since the 70s with the civil spatial programs for remote sensing purpose. Nowadays, orbital imaging systems are equipped with direct orientation sensors. However, the images corrected using the orientation data (ephemeris and attitude) provided by these sensors are not always suitable for applications that require high metric accuracy. As a consequence, it is necessary to estimate indirectly the orientation elements of these images using ground control elements in the object space (points, lines and area), or to correct the orbital parameters using these control elements. The aim of this work is to study, adapt and experimentally assess rigorous bundle block adjustment models for orbital imagery using points and lines as control elements.

Abstract:
The Oseberg ship is known as one of the finest surviving artifacts from the Viking age, with origins dated back to the 800s. The ship has been displayed in the Viking ship museum in Oslo since 1926. The nearly 100 years on museum display along with the over 1000 years it was buried has weakened the structure of the ship. To slow down the deterioration, several research projects has been initiated, among them the project ''Saving Oseberg''. A part of ''Saving Oseberg'' is contributing to the planning of a new museum for the ship. As a basis for the planning, the ship has been monitored with photogrammetry. This is intended as a way to visualise the deformation and displacements of the ship due to seasonal changes in indoor temperature and humidity. In this thesis the photogrammetry data from the hull of the ship was used to make a finite element model, and through this model calculate the average strain on each element. The method was based on a previous research project conducted on the Swedish warship Vasa by a research group at the Division of Applied Mechanics at Uppsala University. The measurements of the ship was formed into a hull by Delaunay triangulation. The strain was approximated as a Green strain and evaluated using isoparametric mapping of the elements. Through the nodal displacements, the strain was evaluated by approximating the elements as tetrahedrons and calculating the average strain from these elements between the measurements. The result showed an oscillating behavior of the displacements, proving the proposal of seasonal depending displacements. The measured principal strains also matched to the corresponding relative humidity fluctuation during the year. The strain magnitude was relatively even throughout the ship, mostly varying between ±0.4% but certain areas were more subjected than others. A few elements on the starboard side showed very large strains through most of the measurements, this seemed very unusual and was probably the result of inaccuracies or errors in the data. Though the ship is subjected to relative small strains and permanent displacements after annual cycles, the mechano-sorptive strains may lead to accumulated deformation and eventually failure in the weak parts of the wood or at the high stress concentraion parts. In addition, the cyclic strain even in elastic range may cause fatigue failure in any material which could pose a large threat for the future conservation of the ship.

Neste trabalho apresenta-se o desenvolvimento e avaliação de um sistema de reconstrução 3D por luz estruturada. O sistema denominado de Scan3DSL é baseado em uma câmara digital de pequeno formato e um projetor de padrões. O modelo matemático para a reconstrução 3D é baseado na equação paramétrica da reta formada pelo raio de luz projetado combinado com as equações de colinearidade. Uma estratégia de codificação de padrões foi desenvolvida para permitir o reconhecimento dos padrões projetados em um processo automático. Uma metodologia de calibração permite a determinação dos vetores diretores de cada padrão projetado e as coordenadas do centro de perspectiva do projetor de padrões. O processo de calibração é realizado com a aquisição de múltiplas imagens em um plano de calibração com tomadas em diferentes orientações e posições. Um conjunto de algoritmos de processamento de imagens foi implementado para propiciar a localização precisa dos padrões e de algumas feições, como o centro de massa e quinas. Para avaliar a precisão e as potencialidades da metodologia, um protótipo foi construído, integrando uma única câmara e um projetor de padrões. Experimentos mostram que um modelo de superfície pode ser obtido em um tempo total de processamento inferior a 10 segundos, e com erro absoluto em profundidade em torno de 0,2 mm. Evidencia-se com isso a potencialidade de uso em várias aplicações.
The purpose of this work is to present a structured light system developed. The system named Scan3DSL is based on off-the-shelf digital cameras and a projector of patterns. The mathematical model for 3D reconstruction is based on the parametric equation of the projected straight line combined with the collinearity equations. A pattern codification strategy was developed to allow fully automatic pattern recognition. A calibration methodology enables the determination of the direction vector of each pattern and the coordinates of the perspective centre of the pattern projector. The calibration processes are carried out with the acquisition of several images of a flat surface from different distances and orientations. Several processes were combined to provide a reliable solution for patterns location. In order to assess the accuracy and the potential of the methodology, a prototype was built integrating in a single mount a projector of patterns and a digital camera. The experiments using reconstructed surfaces with real data indicated a relative accuracy of 0.2 mm in depth could be achieved, in a processing time less than 10 seconds.

Nos últimos anos observa-se uma crescente utilização de câmaras digitais em Fotogrametria, especialmente os modelos profissionais de câmaras de pequeno e médio formato. Isso porque os sistemas digitais comerciais de grande formato possuem custos elevados e um complexo sistema de gerenciamento, armazenamento e processamento das imagens. Além disso, as câmaras digitais de pequeno e médio formato possuem algumas vantagens que as tornam altamente atrativas, como: grande disponibilidade no mercado; flexibilidade quanto ao intervalo de focalização; são pequenas, leves e de fácil manejo e; possuem custos substancialmente reduzidos quando comparadas aos sistemas digitais de grande formato. Por outro lado, algumas limitações ainda estão presentes nestes modelos de câmaras, no que se refere à confiabilidade da geometria interna e à resolução dos sensores. Contudo, estudos de caso têm mostrado que estes problemas podem ser contornados, podendo-se utilizar todo o potencial deste tipo de sensor para mapeamentos temáticos, topográficos e cadastrais em áreas de pequeno e médio porte, com grande flexibilidade em relação aos sensores aéreos e orbitais convencionais. Neste contexto, este trabalho teve como objetivo a concepção, implementação física e testes reais de um sistema de aquisição de imagens digitais, formado por câmaras digitais de médio formato integradas a sensores de orientação direta, dispositivos eletrônicos e interfaces de hardware e software. Foram desenvolvidos também estudos, análises, algoritmos e programas computacionais de Fototriangulação com parâmetros adicionais (FPA), com dados de georreferenciamento direto, voltados ao sistema desenvolvido...
In the last years there is a growing use of digital cameras in Photogrammetry, mainly the small and medium format cameras, because of high cost and problems with the images management and postprocessing in the high end digital cameras. Besides, if the small and medium format cameras are calibrated they can provide quality data, together with their advantages: variety in the market; focalization flexibility; are small, light, easy handling and; have low cost if compared with the high resolution cameras. Although, these models of digital cameras have some limitations, like the interior orientation reliability and the resolution of the sensor. Some case studies have showed that these problems can be solved and the digital sensors can be used with success in thematic, topographic and cadastral mapping of small and medium areas, with high flexibility if compared with conventional aerial and orbital sensors. In this context, the aim of this work is the conception, development and real tests performing of a digital image acquisition system composed by medium format digital cameras integrated to direct orientation systems, electronic devices and hardware and software developments. Studies, analysis and computational programs related to block triangulation with additional parameters with direct orientation data were performed for establishing the interior orientation of the cameras that compose the acquisition system...

Resumo: Nos últimos anos observa-se uma crescente utilização de câmaras digitais em Fotogrametria, especialmente os modelos profissionais de câmaras de pequeno e médio formato. Isso porque os sistemas digitais comerciais de grande formato possuem custos elevados e um complexo sistema de gerenciamento, armazenamento e processamento das imagens. Além disso, as câmaras digitais de pequeno e médio formato possuem algumas vantagens que as tornam altamente atrativas, como: grande disponibilidade no mercado; flexibilidade quanto ao intervalo de focalização; são pequenas, leves e de fácil manejo e; possuem custos substancialmente reduzidos quando comparadas aos sistemas digitais de grande formato. Por outro lado, algumas limitações ainda estão presentes nestes modelos de câmaras, no que se refere à confiabilidade da geometria interna e à resolução dos sensores. Contudo, estudos de caso têm mostrado que estes problemas podem ser contornados, podendo-se utilizar todo o potencial deste tipo de sensor para mapeamentos temáticos, topográficos e cadastrais em áreas de pequeno e médio porte, com grande flexibilidade em relação aos sensores aéreos e orbitais convencionais. Neste contexto, este trabalho teve como objetivo a concepção, implementação física e testes reais de um sistema de aquisição de imagens digitais, formado por câmaras digitais de médio formato integradas a sensores de orientação direta, dispositivos eletrônicos e interfaces de hardware e software. Foram desenvolvidos também estudos, análises, algoritmos e programas computacionais de Fototriangulação com parâmetros adicionais (FPA), com dados de georreferenciamento direto, voltados ao sistema desenvolvido...

Abstract: In the last years there is a growing use of digital cameras in Photogrammetry, mainly the small and medium format cameras, because of high cost and problems with the images management and postprocessing in the high end digital cameras. Besides, if the small and medium format cameras are calibrated they can provide quality data, together with their advantages: variety in the market; focalization flexibility; are small, light, easy handling and; have low cost if compared with the high resolution cameras. Although, these models of digital cameras have some limitations, like the interior orientation reliability and the resolution of the sensor. Some case studies have showed that these problems can be solved and the digital sensors can be used with success in thematic, topographic and cadastral mapping of small and medium areas, with high flexibility if compared with conventional aerial and orbital sensors. In this context, the aim of this work is the conception, development and real tests performing of a digital image acquisition system composed by medium format digital cameras integrated to direct orientation systems, electronic devices and hardware and software developments. Studies, analysis and computational programs related to block triangulation with additional parameters with direct orientation data were performed for establishing the interior orientation of the cameras that compose the acquisition system...

Abstract:
Usage of aerial oblique cameras and oblique images in generation of 3D city models has become popular all over the world in recent years and various solutions has been developed involving specialized methods and softwares. The first comprehensive step in this field was taken by Konya Metropolitan Municipality in Turkey in 2012 and the project undertaken by GEOGIS has been successfully completed in February 2014. It is the first time in Turkey that 3D city model of this large scale has been generated. The project involves: Aerial image acquisition of the project area with vertical and oblique cameras respectively and photogrammetric triangulation; Development of OttoPenta software, which can display oblique images in pentaview screen, make spatial queries and also can measure the horizontal, vertical distance and area; Digitization of roof and roof structures from vertical stereo images using photogrammetric interpretation techniques and generation of 3D solid building models using this data; Assigning building ID numbers to solid models to integrate with the GIS data of the Municipality that is available in Oracle Spatial database; Automatic texturing of 3D models with oblique images; Exporting of textured 3D models into Oracle Spatial Database in CityGML format, complying the OGC standards; and development of KNVCity software, to create and publish the 3D city guide on WEB and mobile devices. The goal of this paper is sharing the experience and knowledge that was gained during the 3D City modeling and 3D city guide project which was performed for the first time in Turkey.
