Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0025] figure 1 It is a flow chart of the method for extracting surface defects of a workpiece based on superpixels in the present invention. Such as figure 1 As shown, the superpixel-based workpiece surface defect extraction method includes the following steps:
[0026] Step S1: the workpiece surface image is divided into blocks, and the processed workpiece surface image is directly collected by an industrial camera, and the acquired image is image-divided, so that the image is divided into sub-image blocks of m*m pixel size;
[0027] Use an industrial camera to collect a complete image of the surface of the workpiece to be inspected, and the size of the obtained image is 2048*1536. Select a certain side length of the...
