Abstract

This invention relates to equipment and its method for detecting the object corner and distance using a sole lens. It comprises a sole charge-coupled device (CCD) lens, a main controlling computer, and a machine body. The detecting method comprises the following procedures: firstly, the CCD lens directly extracts the concrete contour line of object by the sole CCD. Further, via image analysis, it executes the analysis of the contour outline information for image. Furthermore, using cutting line slope comparison algorithm, by means of two secants, it discovers all corners in the outline edge that conforms the corner characteristic in the cutting line image. At the same time, it computes the object correct data. Moreover, it recognizes the distance between the object and the lens, the relative azimuth of the object and the lens, and the azimuth of the obstacle. Eventually, It accurately controls the machine body, and avoids the object or foreign work movement.
