Extracting stripe center accurately is very important in 3D measurement with structured light. A new method for extracting the center of ring-structured-light stripe has been proposed, which combines morphological thinning with improved barycenter method. Convert the original gray-scale image to a binary one, in which stripe stroke at pixel-level can be(More)
Error elimination is very important in 3D measurement with ring-structured-light. A method has been proposed, which includes the following procedures. First, acquire ring-structured-light images and extract their stripe center. Second, find the base-circle center of the stripe center locus by curve fitting, using the least squares method. Subsequently(More)
In 3D measurement of complex deep-hole inner profile with ring-structured-light, the effective area of the original images is an annular zone, only a small portion of the whole. A new image compression storage method has been proposed, where only the image information of the effective annular zone, denoted by T, is stored. The method consists of the(More)
