Full textIn agriculture, the global grain harvest reached several billion tons each year. Cereal producers exchange their crops at a price determined by the quality of their production. This assessment, called grading, is performed for each set on a representative sample. The difficulty of this assessment is to fully characterize the sample. To do so, it is necessary to qualify each of its elements. In other words, it is necessary to evaluate each individual cereal grain. Historically, this has been performed manually by an operator who isolates each evaluated grain. This method is exposed to various problems: firstly, results obtained by an operator are not perfectly repeatable. For example, eyestrain can influence the assessment. On the other hand the evaluation depends on the operator: it is not reproducible. The results can vary from one operator to another. The aim of this thesis is to develop a system that can handle this visual inspection. In a first time, the acquisition system is introduced. Image acquisition and lighting parts are placed in a cabin. Several methods have been introduced to manage accuracy and stability of the acquisitions. Then, a shape model learning is detailed: this step, based on an image with manually separated objects, defines and modelizes shape of the considered cereal grains (wheat, rice, barley). Two detection approaches are then introduced: a deterministic method and a probabilistic one. Both are based on the same tools to process the objects segmentation of an image, but they deal with the question in a different way. The results provided by the system and presented in this thesis emphasize the ability of this automatic system to process the visual inspection of food products

Full textThe increasing use of the Web as a software platform together with the advance of technology has promoted Web applications as a start point for delivering information and services. Facing to the ever growing number of users, usability became a major requirement for the universal access of Web applications. In the last years, a number of evaluation methods have been developed by researchers, practitioners and Information Technology companies to help organizations to identify and to fix usability problems. However, usability evaluation of Web sites is not a straightforward process. On one hand, usability evaluation requires some knowledge and expertise in software ergonomics. One the other hand, due to constant evolution of Web application, it is required frequent evaluations to make sure that content updates do not introduce new usability problems. In order to overcome these limitations, much effort has been devoted in the development of tools for automating the inspection of usability and accessibility guidelines. However, tools currently available can only evaluate the final applications. In this thesis we propose a model-based evaluation method that allows ensuring the ergonomic quality of Web applications throughout the lifecycle. .

Full textAlthough studied since 1970, automatic visual inspection on production lines still struggles to be applied on a large scale and at low cost. The methods used depend greatly on the availability of domain experts. This inevitably leads to increased costs and reduced flexibility in the methods used. Since 2012, advances in the field of Deep Learning have enabled many advances in this direction, particularly thanks to convolutional neura networks that have achieved near-human performance in many areas associated with visual perception (e.g. object recognition and detection, etc.). This thesis proposes an unsupervised approach to meet the needs of automatic visual inspection. This method, called AnoAEGAN, combines adversarial learning and the estimation of a probability density function. These two complementary approaches make it possible to jointly estimate the pixel-by-pixel probability of a visual defect on an image. The model is trained from a very limited number of images (i.e. less than 1000 images) without using expert knowledge to "label" the data beforehand. This method allows increased flexibility with a limited training time and therefore great versatility, demonstrated on ten different tasks without any modification of the model. This method should reduce development costs and the time required to deploy in production. This method can also be deployed in a complementary way to a supervised approach in order to benefit from the advantages of each approach

"Inspection d'assemblages aéronautiques par vision 2D/3D en exploitant la maquette numérique et la pose estimée en temps réel Three-dimensional point cloud analysis for automatic inspection of complex aeronautical mechanical assemblies Automatic inspection of aeronautical mechanical assemblies by matching the 3D CAD model and real 2D images."

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 textNowadays, one of the major problems facing the inter professional dairy laboratories, is that of a rapid transfer of the analysis results to the producers as well as the factories. An integrated system for collection and distribution of data processing results has been developed and installed in Amilly laboratories. Each automatic analyser, coupled with an acquisition and pre-processing system, uses a mini computer equipped with the specific interfaces. All these acquisition system are connected, as a network, to the central computer which assembles the results and manages the data base. A multiple output facility provides the results, for the dairy producers and farmers, in either printed or fast reference forms. Summary statements are drawn up for the veterinary services in charge of the livestock. Certain results, based on computing informations, are prepared to use by the dairy control service. The system takes into account the specific limitations of this type of data as regards the viability, stocking and the availability of the data on line for a long period of usage
