Abstract:
1. An obstacle determination system implemented through utilizing bird's-eye-view images, comprising: a plurality of image fetching devices, installed on a vehicle and that are used to obtain a plurality of images around said vehicle; an image processor, used to convert said images respectively into a plurality of independent bird's-eye-view images, wherein, said independent bird's-eye-view images of two adjacent regions contain said image of an overlapped region; and an obstacle detection unit, used to compare correlation of said overlapped regions in said independent bird's-eye-view images of said two adjacent regions, and determine existence of an obstacle based on said correlation, said obstacle detection unit being used to divide said overlapped region in said independent bird's-eye-view images of said two adjacent regions into a plurality of sub-regions, calculate and obtain a correlation coefficient of said sub-region of said overlapped regions in said independent bird's-eye-view images of said two adjacent regions, and determine if said obstacle exists in said sub-region based on said correlation coefficient, hereby obtaining a distance between said vehicle and said obstacle.
