Embodiment Construction
[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0019] Such as figure 1 Shown, a kind of PCB board defect detection method based on depth information, described method comprises the following steps:
[0020] Collect the depth data of the PCB board to be tested and the standard PCB board respectively, use the line laser to scan the front and back of the standard PCB board, and collect the depth data of the front and back of the board;
[0021] According to the depth data of the two PCB boards, corresponding depth images are generated respectively;
[0022] Obtain the standard image according to the depth image of the standard PCB board, obtain the image to be tested according to the depth image of the PCB board to be inspected, perform filtering operation on the obtained depth image to remove n...
