Abstract

The application provides a dispensing defect detection method, device and equipment of a circuit board and a storage medium, and relates to the field of dispensing defect detection. In the application, a gray-scale image of a to-be-detected region in a collected circuit board image is obtained; image segmentation is performed on the gray-scale image of the to-be-detected region according to the gray-scale values of each pixel point in the gray-scale image and a gray-scale threshold segmentation condition corresponding to a set dispensing defect detection type, to obtain a target region in the to-be-detected region; and whether the circuit board has a dispensing defect is determined according to the size of the target region. In the application, the gray-scale threshold segmentation condition corresponding to the set dispensing defect detection type is determined based on the dispensing defect detection type, the gray-scale image of the to-be-detected region is segmented, the target region corresponding to the dispensing defect detection type is obtained, multiple dispensing defect detections are performed based on the obtained circuit board image, and thus the efficiency of dispensing defect detection is improved.
