Description

Optical recognition detection device and optical recognition detection method Technical Field The present invention relates to an optical recognition and detection device and an optical recognition and detection method, and more particularly, to an optical recognition and detection device and an optical recognition and detection method capable of judging a coating film thickness. Background As shown in fig. 1, after a layer of film F is sprayed on a material S by the spraying mechanism P, if the color of the material S is similar to that of the film F, the color difference cannot be used to identify whether the film F is coated or not, so that the image capturing mechanism C is required to capture the image of the sprayed material S, and compare the image with the geometric difference of the appearance of the sprayed material S. However, when the coating range is too narrow, errors are easily interpreted. In addition, in the production line, the material S is dynamically moved along the conveying track T, and it is difficult to measure the thickness of the sprayed film F.
