VEHICLE SURROUNDING VIEW GENERATING METHOD CAPABLE OF AUTOMATICALLY CORRECTING A DISTORTION IMAGE BY ESTIMATING DISTORTION POLYGONS IN THE DISTORTION IMAGE

摘要

PURPOSE: A vehicle surrounding view generating method is provided to correct a distortion image by moving a selection area of the image to a correction position through a polygon mapping method.;CONSTITUTION: A reference coordinate value for each cross point of a grid pattern is set(S20). A reference image is generated(S30). An edge of a check board pattern is detected from a distortion image generated by photographing the check board pattern(S50). A correction sequence for estimated compensation points is selected(S60). The distortion image is divided into plural distortion polygons(S70). Each pixel coordinate of the distortion image is mapped with reference pixel coordinates(S80). A surrounding view image is generated(S90).;COPYRIGHT KIPO 2013;[Reference numerals] (S10) Generating a grid pattern; (S20) Setting a reference coordinate value for each cross point of the grid pattern; (S30) Setting reference polygon division of a reference image and setting the reference coordinate value; (S40) Obtaining a distorted image by photographing a check board pattern; (S50) Detecting an edge of the check board pattern; (S60) Estimating a correction point and selecting a correction sequence; (S70) Dividing the distorted image into plural distorted polygons; (S80) Mapping the distorted polygons with a reference polygon according to the correction sequence; (S90) Generating an around view image by combining correction images and vehicle flat images
