COMPUTING DEVICE AND METHOD FOR ANALYZING PROFILE TOLERANCES OF PRODUCTS

摘要

A computing device reads pixels of an image of a product along an x-direction and a y-direction of the image. In response to reading two neighboring pixels having different color values, the device regards one pixel having a predetermined color value from the two neighboring pixels as a profile point of the image, to generate one or more point-clouds consisting of all profile points of the image. Furthermore, the device reads one or more theoretical profile curves of the product from the storage device, aligns the one or more point-clouds and the one or more theoretical profile curves, and determines a minimum distance from each profile point in the one or more point-clouds to the one or more adjusted theoretical profile curves. A profile tolerance of the product is then determined according to a maximum value and a minimum value of the minimum distances.
