This paper presents a kind of correction method for structured light image's outlineextraction which is feasible when the scanned object is of the same reflectance. The 3D laser scannerscan the object’s surface and intensity of the reflected light is decided by the facet normal. The newmethod use this principle to correct the extraction outline resulting from the traditional method as theloss of laser stripe do a lot of error and the simple way can’t get rid of it. With this new method theextraction error d...
