Research of locating robot color patch based on color vector analysis algorithm

This paper mainly proposes the method of locating robot based on vision and uses method based on color patch to locate robot. The knowledge about image sharpening and smoothing with emphasis on RGB color vector analysis algorithm is introduced in this paper. In preprocessing for colorful image, the main method includes image smoothing and image sharpening, image sharpening has many ways; different ways have different effect. This paper proposes Laplacian operator, which does best in eliminating noise and anti- disturbance, to sharpen colorful image. In testing color target, this work proposes the method for locating color patch based on RGB color vector analysis algorithm to identify image directly, saving the transformation time of color space. This algorithm does best in timeliness, precision, anti-disturbance and adaptability. The effect in practical application is also good.
