[Termes descripteurs IGN] système de numérisation mobileRésumé : (Auteur) The vehicle-based Pelican radar system is used in the context of mobile mapping. The R-SLAM algorithm allows simultaneous retrieval of the vehicle trajectory and of the map of the environment. As the purpose of Pelican is to provide a means for gathering spatial information, the impact of distortion caused by the topography is not negligible. This article proposes an orthorectification process to correct panoramic radar images and the consequent R-SLAM trajectory and radar map. The a priori knowledge of the area topography is provided by a digital elevation model. By applying the method to the data obtained from a path with large variations in altitude it is shown that the corrected panoramic radar images are contracted by the orthorectification process. The efficiency of the orthorectification process is assessed firstly by comparing R-SLAM trajectories to a GPS trajectory and secondly by comparing the position of Ground Control Points on the radar map with their GPS position. The RMS positioning error moves from 5.56 m for the raw radar map to 0.75 m for the orthorectified radar map.

[Termes descripteurs IGN] télémétrie laser terrestreRésumé : (auteur) River monitoring is an important component of sustainable management and preservation of water resource. Surveys have to be regularly performed. In this context, an alternative surveying procedure using a boat-borne radar is presented. This method is compared to two other techniques: infrared aerial photogrammetry and mobile laser scanning in order to assess their convenience to delineate the stream channel. As in steep-sided river valleys the delineation of the stream channel is particularly complex, the study focuses on two reaches of respectively 23 km and 2 km long, along the Ardeche River (France) where the three techniques have been put to the test. Some specific situations such as effects of the overhanging cliffs have been taken into account to complete the study. Finally a comparison of the adequacy of the systems with respect to the conditions of use, cost of equipment, operational costs and data volume was carried out.

[Termes descripteurs IGN] transformation de FourierRésumé : (Auteur) In a context of mobile environment mapping, a vehicle-based radar system, K2Pi, has been developed. A mapping of the environment is carried out from the radar datasets. Given the specificities of radar maps, the main problem at this stage is to find a method to georeference these maps. This article proposes three radar map georeferencing methods. The first method is a typical manual selection of a set of control point pairs. The second method consists of matching the relative trajectory computed by a specific radar algorithm with a trajectory recorded from absolute DGPS recording. Finally, the third method, inspired by the image-to-image approach, is based on Fourier-Mellin transform which automatically registers the radar map with respect to a georeferenced aerial photograph. Successfully tested on radar datasets, this method could be applied to many other types of data.
