摘要： PROBLEM TO BE SOLVED: To provide a speed sensor and a speed sensor program for measuring a ground actual speed of an agrimotor and the like in a field with high precision at a low cost without influence of a tire slip and the like. SOLUTION: A reference image is acquired, and after a lapse of predetermined time, a collation objective image to be collated is acquired. A template image is extracted from the reference image and a maximum brightness gradient direction of pixels constituting the template image is acquired as a code, while a search area in a predetermined range is selected from the collation objective image for acquiring a maximum brightness gradient direction of pixels constituting the search area as a code. As a result of collation using a total sum of residual absolute values obtained by comparing the maximum gradient direction of the template image and that of the search area, an identical similar image giving a minimum error between the respective direction codes of the template image is specified in the search area, and the number of moved pixels is calculated by comparison between the template image and the identical similar image. Based on the number of moved pixels, an actual speed of a mobile body is calculated. COPYRIGHT: (C)2006,JPO&NCIPI
