Full textThe interest for digital models in the building industry is growing rapidly. These centralize all the information concerning the building and facilitate communication between the players of construction : cost evaluation, physical simulations, virtual presentations, building lifecycle management, site supervision, etc. Although building models now tend to be used for large projects of new constructions, there is no such models for existing building. In particular, old buildings do not enjoy digital 3D model and information whereas they would benefit the most from them, e.g., to plan cost-effective renovation that achieves good thermal performance. Such 3D models are reconstructed from the real building. Lately a number of automatic reconstruction methods have been developed either from laser or photogrammetric data. Lasers are precise and produce dense point clouds. Their price have greatly reduced in the past few years, making them affordable for industries. Photogrammetry, often less precise and failing in uniform regions (e.g. bare walls), is a lot cheaper than the lasers. However most approaches only reconstruct a surface from point clouds, not a semantically rich building model. A building information model is the alliance of a geometry and a semantics for the scene elements. The main objective of this thesis is to define a framework for digital model production regarding both geometry and semantic, using point clouds as an entry. The reconstruction process is divided in four parts, gradually enriching information, from the points to the final digital mockup. First, we define a normal estimator for unstructured point clouds based on a robust Hough transform. It allows to estimate accurate normals, even near sharp edges and corners, and deals with the anisotropy inherent to laser scans. Then, primitives such as planes are extracted from the point cloud. To avoid over-segmentation issues, we develop a general and robust statistical criterion for shape merging. It only requires a distance function from points to shapes. A piecewise-planar surface is then reconstructed. Planes hypothesis for visible and hidden parts of the scene are inserted in a 3D plane arrangement. Cells of the arrangement are labelled full or empty using a new regularization on corner count and edge length. A linear formulation allow us to efficiently solve this labelling problem with a continuous relaxation. Finally, we propose an approach based on constrained attribute grammars for 3D model semantization. This method is entirely bottom-up. We prevent the possible combinatorial explosion by introducing maximal operators and an order on variable instantiation

Full textThe construction show a lack of efficiency to compare to other industries. This is explained by the insufficiency to computerize the design of building. In answer, the world of architecture set up a new process called BIM (Building Information Modeling). This process is based on a3D virtual mock up containing every information needed for the construction. During the implementation of this process, difficulties of interaction has been noted by the BIM users.BIM models are hard to observe and manage, explained by the fact that these models contain a large amount of information. Moreover, the collaborative idea of the BIM is not considered in the actual method. BIM process proposes the same scheme for all the construction profile. This thesis proposes an adapted methodology of interaction for the inspection of architectural projects, using artificial intelligence tools or more particularly virtual reality technologies. The purpose is to offer an adapted environment, considering the profile of each BIM user, while keeping the actual design method. Firstly, this document describes the creation of virtual reality rooms dedicated to the construction. Secondly, it deals with the development of algorithms allowing the classification of components from BIM model, an adaptive system of visualization and a process to handle the model. These development are based on the consideration of the profile of the user, the trade of the user

Full textThe creation of an as-built BIM requires the acquisition of the as-is conditions of existing buildings. Terrestrial laser scanning (TLS) is widely used to achieve this goal. Indeed, laser scanners permit to collect information about object geometry in form of point clouds. They provide a large amount of accurate data in a very fast way and with a high level of details. Unfortunately, the scan-to-BIM process remains currently largely a manual process because of the huge amount of data and because of processes, which are difficult to automate. It is time consuming and error-prone. A key challenge today is thus to automate the process leading to 3D reconstruction of existing buildings from point clouds. The aim of this thesis is to develop a processing chain to extract the maximum amount of information from a building point cloud in order to integrate the result in a BIM software

Full textNew generation cryogenic upper-stage rocket engines are planned to be restartable during the orbit mission. The re-ignition of the engine is particularly difficult in space flight conditions. The engine contains a LOX dome fed with liquid oxygen (LOX) supplied by a bushel valve through a pipe. The gas / liquid mixture forming in the dome is injected into the combustion chamber through a number of injectors. Therefore the two-phase flow distribution at injectors outlet carries a real importance in terms of the ignition from the opening to the closing phases of the main valve. These flight conditions are of paramount importance, however, they are truly difficult to reproduce by experimental ground tests. In the framework of these studies, a research program set up by CNES (the French Space Agency) and SAFRAN Snecma, tries to study the LOX dome filling, through experiments and numerical studies. The aim is to identify the phenomena at sake to know the limit conditions at injectors, which will determine the ignition stage in the combustion chamber. Experiments are carried out at LEGI (Geophysical and Industrial Flows Laboratory in Grenoble) with substitution fluids (air and water), without heat and mass transfer on a rocket engine mockup. The work presented here, conducted at IMFT (Fluid Mechanics Institute in Toulouse), intends to reproduce the experimental results using incompressible two-phase flow simulations. The geometry used is representative of the experimental mockup composed of a feeding pipe, a dome, an igniter pipe and injectors. The aim of this study is to demonstrate the feasibility of a 3D unsteady two-phase flow calculation with the industrial code NEPTUNE_CFD, to simulate the LOX dome filling of the rocket engine, by taking into account the real geometry and the preponderant physical phenomena. The comparison of the predictions with the experimental results is carried out in order to estimate the code capability to predict the flow behavior, according to available closure laws. Finally, several sensitivity studies on the closure laws have been conducted to assess their influence on the numerical results. An important work has been carried out to obtain the proper inlet conditions to be imposed in the code in coherence with the experiments. Studies have equally been conducted on an isolated injector

Full textThe variability of the surface temperatures resulting from the coupling between energy and radiative transfers within canopies is prone to induce a strong directional anisotropy of measurements in the thermal infrared (TIR). A modelling approach developed for complex canopies is described. It is based on the combination of 3D models providing the information about the distribution of the elements of the canopy seen by the sensor, with transfer models computing the surface temperatures of the facets. The aggregation of radiances allows one to derive the directional temperature and the anisotropy by subtracting the nadir temperature. Two canopies are studied: a stand of maritime pine (in Landes de Gascogne, SW France) and a urban area (Toulouse city studied in the framework of the CAPITOUL experiment). For the forest canopy, a simplified 3D model concentrating all the foliage within cylinders is associated to a parametric model of hot spot which allows one to take into account the microscale effects related to needles and to their spatial distribution. The MuSICA model (developed at INRA) provides the temperatures of the crowns and herbaceous underneath layer at the ground. For the urban canopy, the SOLENE model (developed at CERMA, Nantes ) and the TEB model (developed at Météo France) are combined with the 3D model of Toulouse to simulate the TIR anisotropy both in daytime and nightime conditions. The simulations are compared against airborne measurements of anisotropy. For daytime conditions, the hot spot effects are satisfactorily reproduced with however a 15% underestimation, while the nightime directional anisotropy over the urban canopy is correctly simulated. The results are discussed and improvements proposed

Full textThis thesis makes part of a research aimed towards innovative digital tools for the service of what is commonly referred to as Factory of the Future. Our work was conducted in the scope of the joint research laboratory "Inspection 4.0" founded by IMT Mines Albi/ICA and the company DIOTA specialized in the development of numerical tools for Industry 4.0. In the thesis, we were interested in the development of systems exploiting 2D images or (and) 3D point clouds for the automatic inspection of complex aeronautical mechanical assemblies (typically an aircraft engine). The CAD (Computer Aided Design) model of the assembly is at our disposal and our task is to verify that the assembly has been correctly assembled, i.e. that all the elements constituting the assembly are present in the right position and at the right place. The CAD model serves as a reference. We have developed two inspection scenarios that exploit the inspection systems designed and implemented by DIOTA: (1) a scenario based on a tablet equipped with a camera, carried by a human operator for real-time interactive control, (2) a scenario based on a robot equipped with sensors (two cameras and a 3D scanner) for fully automatic control. In both scenarios, a so-called localisation camera provides in real-time the pose between the CAD model and the sensors (which allows to directly link the 3D digital model with the 2D images or the 3D point clouds analysed). We first developed 2D inspection methods, based solely on the analysis of 2D images. Then, for certain types of inspection that could not be performed by using 2D images only (typically requiring the measurement of 3D distances), we developed 3D inspection methods based on the analysis of 3D point clouds. For the 3D inspection of electrical cables, we proposed an original method for segmenting a cable within a point cloud. We have also tackled the problem of automatic selection of best view point, which allows the inspection sensor to be placed in an optimal observation position. The developed methods have been validated on many industrial cases. Some of the inspection algorithms developed during this thesis have been integrated into the DIOTA Inspect© software and are used daily by DIOTA's customers to perform inspections on industrial sites

Full textThis thesis is built around two main subjects: the first pertains to the question of improving the technics of study related to the reconstitution of ancient ships following a renewal of in tools utilized for the task. The second subject is linked to the production of additional information on the nautical qualities and the sailing capabilities of the hypothetical reconstituted ships based on the analysis of virtual models. We applied this program to four wrecks: a Greek wreck from the archaic period dated to the VIth c. B.C., Jules-Verne 7, two Roman wrecks from the Ist c. A.D., Napoli A and Napoli C, and finally to a late roman period wreck from the Vth c. A.D., Dramont E. For each wreck, the study is divided into two separate sections that are closely related and interdependent. First, we sought to define one or more valid hypotheses based rigorously on the remains preserved and on various elements of comparison (iconographic and ethnographic parallels, literary sources). Thereafter, we planned a simple analysis of some physical characteristics of the reconstituted ship focusing on its various draughts, displacements and transversal stability according to different distributions of weights and volumes. This focus on the characteristics of the hypotheses of reconstitution allows us, to some extent, to outline in broad terms the utilization programs and the navigational areas of the original ships. We intend in this way to focus on the ship as a functional system, but also and especially as the main vector of ancient maritime trade in the Mediterranean
