Full textThe thesis subject concerns the automatic recognition of points of interest (PI) for an inspection robot in a constrained and degraded environment. The objective of this thesis work is to develop a robotic platform capable of carrying out autonomous missions based on detected visual and chemical PIs, a so-called bimodal problem. The combination of visual and chemical percepts optimizes localization accuracy and ensures information redundancy. The field of study concerns 3 application cases: case 1, the inspection is carried out in a confined space (industrial environment). Case 2, the inspection is carried out in an environment with a proven risk of loss of signal and predominantly rocky (mine, underground quarry). Case 3, the inspection is carried out in an environment that has undergone significant deformations and therefore a modified and chaotic geometry of the inspection sites (natural disasters such as earthquakes or landslides in an urban environment). In this study, a contextual case analysis method is proposed and presented in order to analyze the constraints of the different complex environments for the robotic solution. The thesis therefore brings together different issues: the study of environmental constraints, the choice of the robotic solution, autonomous navigation and visual and chemical servoing. Following this contextual analysis, a state of the art is oriented on the terrestrial robotic platform to determine the most suitable robotic solution to operate in the 3 application cases. The hexapod robots were chosen for their ability to overcome obstacles, their stability, and their carrying capacity for sensors, in particular. A method is proposed to reach the source of the percept in an unstructured environment by relying on visual and chemical PIs. For the evaluation of the proposed methodology, the visual PIs considered are of the QR code type and the detection of the concentration of a gas concerning chemical servoing. The effectiveness of the proposed scheme is first demonstrated by simulations. Finally, a hexapod prototype is designed, built and developed using the ROS software architecture. The developed hexapod carried out a mission within an industrial environment and inside a shipbuilding including a series of obstacles (case 1 of the study). The results of this robotic approach arefinally presented, commented and discussed

Full textA recognition system for multi font printed documents using contextual informations about typography, structure of document and syntax, has been developed. First, a quick bottom up method to separate text from image and recognize logical structure of documents has been achieved. A mixed approach has been used to recognize individual characters. A first stage realizes a compaction at the character level compared to a dynamically built librairy of shapes. The high redundancy of character's image in printed document justifies this approach. A second stage structurally recognizes the previously built models of characters. A mixed syntaxic and statistic stage is used simultanous. It o perform a high recognition rate
