Abstract

The invention provides a circuit board defect detection method and device, wherein the method comprises the steps of obtaining a shooting image of a circuit board, inputting the shooting image into atrained instance segmentation model, obtaining a target pixel unit output by the instance segmentation model, and enabling the target pixel unit to be a pixel unit presenting defects in the shooting image, wherein the instance segmentation model learns to obtain image characteristics of the local circuit board with the defect, and defect detection is carried out on the circuit board according to the area proportion of the target pixel unit in the shot image. As the instance segmentation model learns to obtain the image features of the local circuit board with the defects, the target pixel unitwith the defect can be accurately positioned in the shot image, further verification is carried out according to the area proportion of the target pixel unit in the shot image so as to finally determine whether the circuit board has the defect, and the defect detection precision and efficiency of the detected circuit board can be improved.

Description

technical field [0001] The present application relates to the technical field of deep learning and image processing, and in particular to a method and device for detecting defects of circuit boards. Background technique [0002] At present, circuit board manufacturing relies on automated industrial production lines. Due to the increasing integration of electronic components of circuit boards, the production process of circuit boards is becoming more and more complicated. Defective circuit boards will inevitably appear during the process of circuit board generation. Therefore, Defect detection on the circuit board can avoid circuit board damage caused by defects. [0003] In the prior art, circuit board production enterprises mainly use manual detection methods to detect defects on circuit boards. However, manual inspection requires staff to inspect with naked eyes, which has the disadvantages of high detection cost, low accuracy, and low efficiency. Contents of the invent...
