This paper describes an improved stereo vision system for anticipated detection of car-to-pedestrian accidents. An improvement of previous versions of the pedestrian dection system is achieved by compensation of the cameras pitch angle, since it results in higher accuracy in the location of the ground plane and more accurate depth measurements.
The pedestrian detection system has been applied to collision avoidance and mitigation. Collision avoidance is carried out by means of deceleration strategies, whenever the accident is evitable. Likewise, collision mitigation is accomplished by activating an activehood system.
For that purpose, the system has been mounted and tested on two different prototype cars and tested on private circuits using dummies.
