Abstract
A technology of determining obstacles around a vehicle through utilizing bird's-eye-view images; wherein, a plurality of image fetching devices disposed in various positions of said vehicle fetch a plurality of images around said vehicle, said images of two adjacent regions contain at least an overlapped region; an image processor transforms said images into said respective independent bird's-eye-view images; and an obstacle detection unit compares said overlapped region in said independent bird's-eye-view images of two adjacent regions, so as to obtain their correlations, and existence of said obstacle is determined based on said correlations. Moreover, a correspondence table is set up containing a set of space transformation information based on vehicle driving condition information. Therefore, a surrounding bird's-eye-view image of an appropriate visual angle can be produced quickly and a position of said obstacle is marked on said surrounding bird's-eye-view image.
