Street intersections account for a large portion of road accidents. Therefore, a driver assistance system supporting the driver to negotiate intersections is highly desirable. What makes intersection assistance more challenging than other traffic scenarios such as highways and rural roads? The environment all around the vehicle must be monitored. A very large field of view for the local sensors is required. In this paper, the authors focus on the use of two active cameras to perform a stereo analysis of specific areas around us at a high resolution. The analysis following the stereo evaluation is targeted towards an intersection assistant in residential areas at low speed, where the regulation 'right precedes left' is in operation. The required calibration for the stereo analysis is done using a novel active camera calibration approach. They propose an intersection assistant in residential areas using image, map, and GPS information to issue a cross traffic warning.
