Colorisation et texturation temps réel d'environnements urbains par système mobile avec scanner laser et caméra fish-eye
This enables efficient urban mapping for applications like city planning or navigation, but it is incremental as it builds on existing mobile mapping techniques.
The authors tackled real-time 3D modeling of urban environments by developing a mobile mapping system with a laser scanner and fish-eye camera, producing colored point clouds and textured models during acquisition.
We present here a real time mobile mapping system mounted on a vehicle. The terrestrial acquisition system is based on a geolocation system and two sensors, namely, a laser scanner and a camera with a fish-eye lens. We produce 3D colored points cloud and textured models of the environment. Once the system has been calibrated, the data acquisition and processing are done "on the way". This article mainly presents our methods of colorization of point cloud, triangulation and texture mapping.
