Problems solved by technology

For different images to be tested, the default parameters of the color algorithm are fixed, such as figure 1 The brightness range is fixed at 0-255, and the color wheel distribution is fixed at area 13. The adaptive ability is weak and the flexibility is poor. Almost every device frame needs to be adjusted.
In addition, for those who have no programming experience, the default parameters have no reference value, and the appropriate parameters can only be selected through continuous adjustment and trial, which takes a long time

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to a method, device, device and storage medium for generating default parameters in a color algorithm. Background technique [0002] Automated Optical Inspection (AOI) is a device based on optical principles to detect common defects encountered in printed circuit board (Printed Circuit Board, PCB) board welding production. Before the test, make the corresponding PCB board program as the test standard. After the board card flows into the equipment, the equipment will take pictures of the board card and compare it with the prepared standard program to judge whether the board card under inspection is qualified. The color algorithm is the most basic and most commonly used algorithm in AOI. During detection, according to the preset algorithm parameters, the area on the image under test that meets the conditions is obtained to judge whether the image...
