A highlight processing algorithm based on chromaticity space conversion and BSCB is proposed to address the prob-lem that highlight areas are generated due to the strong reflective properties of metal surfaces during image acquisition,result-ing in a large amount of missing information for subsequent 3D reconstruction and thus affecting the measurement accuracy.First,the CIE-XYZ chromaticity space is used to derive the CIE-xyY color space,and the color brightness and luminance are calculated to complete the extraction of highlight areas.Then,BSCB is used to repair the highlight areas and obtain the de-highlighted metal workpiece images.The experimental results show that the method can detect and extract the highlight areas of the photographed metal workpieces with high accuracy and improve the restoration rate of metal highlight images,which has a wide application prospect.
