Title:
VEHICLE COLLISION WARNING METHOD AND APPARATUS, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/080180
Kind Code:
A1
Abstract:
A vehicle collision warning method and apparatus, and a vehicle. Two images, which are obtained by shooting an obstacle through two camera shooting devices, are obtained by means of collection; the two images are calculated based on close range photogrammetry, so as to obtain a distance between the obstacle and a rear portion of a vehicle; and when the distance is less than a pre-set threshold value, a vehicle collision warning is sent out. Since the camera shooting device can use an original vehicle reversing camera of a vehicle, the additional installation of a radar anticollision system is avoided, and the technical problems of higher costs and greater popularity difficulty of using a radar anticollision system to achieve vehicle collision warning in the prior art are solved.
