In this paper,a recognition scheme based on RGB color space image processing is proposed for the rep-resentation recognition of automobile pointer.Firstly,according to the histogram of R,G and B components of the instrument panel image,the center of the circle and the pointer of the instrument panel are divided by the Euclide-an distance method of the component.Then,the frame of the center and the coordinates of the center of the circle are extracted to establish a new coordinate system.Finally,the center of mass of the pointer and the center of the instrument panel are connected into a straight line,and the pointer reading is identified by the position of the straight line.Experimental results show that this method can be used for automatic testing of pointer type automobile instrument.
