Development of a Night Vision System (Vehicle-Pedestrian Collision Avoidance System)

Article of Honda R&D Technical Review Vol.13 No.1


A night vision system has been developed to help reduce vehicle-pedestrian accidents occurring at night. High temperature objects presumed to be pedestrians are detected by processing the images from infrared stereo cameras mounted on the front of the vehicle, and the possibility of a collision is judged by calculating the position and relative moving vector of the pedestrian. In addition, voice guidance is provided and a highlighted infrared image of the pedestrian is displayed at the bottom of the front windshield using a head-up display (HUD) installed in the instrument panel.
As a result of confirming detection performance on a test course, it was found that the possibility of collisions with pedestrians on the road and crossing the road could be judged.
Further, as a result of confirming evasive action on the part of the driver with respect to the provided information, this system was found to be a useful means of reducing vehicle collisions with pedestrians. Further development is needed to bring this kind of system to the point of practical application.
