Environnement de réalité augmentée pour la conception, la gestion et la maintenance d’ouvrages et de mobiliers urbains

Abstract : In the public construction field, surveyors have to manipulate sophisticatedinstruments and maps to design CAD and GIS sketches describing geolocated facilities tobuild on worksite. Geolocation and design inaccuracies happen during these steps and leadto false technical maps. This Ph.D. thesis explains our research works made on behalf ofSIG-IMAGE Company. We first identify origins of inaccuracies during survey, then wepropose a new and optimized survey method that improves CAD and GIS accuracy on field.We explain to what extend Augmented Reality is able to improve technical mapsinterpretation and edition. We present, evaluate and criticize a prototype that couples atangible AR environment with a laser range finder. It allows one to draw technical sketcheson a 2D tangible real time view of worksites. Experiments have proven that it does not satisfyFrench regulation in terms of accuracy when editing maps. However it is accurate enough todisplay and edit GIS information, as well as CAD maps in a very close area. We then exploreanother approach consisting of matching the scanner’s dense point cloud with the real time2D view of the worksite. We propose a synthesis of alignment practices between point cloudsand images of a same scene. Finally we have chosen to explore 2D-2D registration so thatinteractions in our AR system would be based on the point cloud pre-processed discreterepresentation of the worksite. These interactions will be geolocated and will follow thePicking-Outlining-Annotating paradigm.
