In the last years the urban road traffic became overcrowded, requiring higher vigilance from the driver. In order to ensure a better road safety, the car manufacturers compete to offer obstacle detection and representation functions for driver assistance in difficult situations. The fast processing speed and reduced power consumption offered by FPGA devices help overcome the issue of real-time obstacle detection. This paper presents a system that employs an FPGA-based hardware implementation for objects representation. The information about the outside environment is acquired from a stereo vision system placed inside a vehicle, through the CAN (Controller Area Network) bus. The system is capable of rendering detailed objects in real-time, helping the drivers to take fast decisions when confronting difficult situations and avoid accidents.
