Abstract: In a production accuracy verification method to verify a production program installed in a computer numerical control (CNC) machine, wherein the production program is used to produce a product, coordinates of points on an ideal processing path of the production program are obtained to fit a first curve. A CAD model of the product is obtained, and outlines of the product are extracted in the CAD model. A normal vector of each of the outlines is computed and to be adjusted, making the normal vectors of the outlines pointing to a same direction. First distances between points in the first curve and corresponding points in the second curve are computed, and whether the production program is accurate can be determined by comparing whether each of the first distances is within a first predetermined tolerance.

Abstract: A computing device and a method detect a lightness of a lighting device. The computing device captures an image of the lighting device and parses the image to obtain a pixel gray value of each lighting dot of the lighting device. The computing device obtains detection information of the lighting device according to the pixel gray value of each lighting dot of the lighting device. The computing device generates a detection report of the lighting device according to the detection information of the lighting device.
