Abstract
The present disclosure provides a method, device, and vehicle of pre-warning for a vehicle collision. The present disclosure may acquire two images captured by two photographing devices with respect to an obstacle; perform calculation on the two images based on close-range photogrammetry to obtain a distance between the obstacle and the rear of the vehicle; and making a pre-warning for a vehicle collision when the distance is less than a preset threshold. Because the photographing devices may utilize an inherent reversing camera of the vehicle, and avoid additionally providing an anti-knocking radar system, so that it is possible to solve the technical problem in the related art that the system cost for the anti-knocking radar system may be high, which causes difficulty in popularizing.
