Method for perceiving star catalogue topography by laser stripe information

The invention belongs to the field of visual environment perception for a robot, and particularly discloses a method for perceiving star catalogue topography by laser stripe information. In the method, the topography is designed into three regions so as to evaluate perception results in advance; the defect of complex algorithm in lattice-fitting scene description is eliminated; and the provided results and design weights for the subsequent algorithm are applicable to various path planning algorithms. Compared with the traditional binocular stereo vision technology, the invention has the advantages that the speed is higher; an image pair (1024*1024) is matched with the traditional gray scale; a search window is set into the size of 5*5 and adopts an SAD (sum of absolute differences) matching mode; and the matching recovery runs once on an industrial personal computer (IPC) with a main frequency (p42.4) within about 2 minutes. By utilizing the method, points obtained through calculationare reduced, but the reliability is enhanced and the operation time is less than 1 second.
