A SYSTEM ON BOARD A VEHICLE AND AN IMPROVED METHOD FOR THE DETECTION OF OBJECTS IN AN ENVIRONMENT SURROUNDING A VEHICLE

A system on board a vehicle for the detection of objects in an environment surrounding the vehicle is described, including: - at least one image capture device (30) arranged for acquiring images (S) representative of a region of observation in the environment surrounding the vehicle; - a map (16) of a road network, comprising attributes associated with segments of road of the road network, which include geometrical data indicative of the real road; and - a device (12) for positioning the vehicle within the road network, in which a predetermined number of road segments of the road network downstream of the determined position of the vehicle and the attributes associated therewith constitute an electronic horizon (18) of the vehicle, and in which an electronic processing unit (40) connected to the image capture device (30) is arranged for selecting at least one area (A) of the image acquired by the image capture means (30) as a function of the electronic horizon (18) of the vehicle, the aforementioned selected area (A) being representative of a region of interest of the region of observation, whereby the electronic processing unit (40) is arranged for detecting predetermined elements of interest (P) within the region of interest.
