Automobile instrument panel image positioning method based on machine vision

The invention discloses an automobile instrument panel image positioning method based on machine vision, and provides an image positioning method based on machine vision in order to solve the problemof automobile instrument panel image positioning. The automobile instrument panel image positioning method includes the steps: establishing a spatial coordinate and pixel coordinate relationship through nine-point calibration; under the coordinate system, adopting a PatQuick algorithm to coarsely position an automobile instrument panel, after positioning, marginalizing an image according to a Sobel operator, then positioning scale lines finely through a Blob algorithm; and finally, finely positioning a liquid crystal display character by combining a PatMax algorithm and the Blob algorithm. Theautomobile instrument panel image positioning method can accurately position the graphic information, reduces the display deviation of the automobile instrument panel, improves the automobile qualityinspection rate, and is of
