<p><P>PROBLEM TO BE SOLVED: To accurately detect a crosswalk from a photographic image by an in-vehicle camera which moves with a vehicle while reducing a load on the arithmetic processing of a control system. <P>SOLUTION: The edge processing of the portion of the image recognition area of a photographic image from a camera 60 loaded on a vehicle is performed by a microcomputer 30, and the high speed Fourier inverse transformation of the edge-processed image signal is performed by image recognition LSI 51, and a zebra pattern having strong periodicity is extracted from the image recognition area. When the periodicity of the extracted zebra pattern is within the range of the periodicity of the crosswalk, it is recognized that the zebra pattern is the crosswalk by the microcomputer 30. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
