[0041] Figure 5 It is the method of the present invention to obtain a new workpiece map with generation defects according to the actual workpiece map with loose texture defects, comprising the following steps:
[0042] (1) Normalize the X-ray image of the actual workpiece with loose texture defects, and cut out suitable defect samples;
[0043] (2) remove the background image in the sample;
[0044] (3) In a new workpiece image, according to the required area size, select a rectangular area as the defect generation area at any desired position of the workpiece;
[0045] (4) Utilize the new texture image generation process shown in Figure (1) to generate a new defect texture image with the same size as the selected defect generation area;
[0046] (5) Superimposing the generated defect texture image on the position of the workpiece image, that is, obtaining a new workpiece image with generated defects. The superposition method is to add the gray value of each pixel in the se...
