AI Technical Summary
Technical Problem
Existing white or monochromatic LED light sources are difficult to adapt to the light wavelength reflection characteristics of different pins and background materials when detecting pins with different materials and surface treatment processes, resulting in poor lighting effects.
Method used
By breaking down a color image into R, G, and B channel images, calculating the contrast score between the pins and the background, selecting the most sensitive color light source for illumination, and optimizing the lighting effect by adjusting the angle and width of the light.
Benefits of technology
It improves the illumination adaptability of pin inspection, ensures the significance of the contrast score between the pin and the background, and enhances the inspection effect.

Abstract
The application discloses a detection method and detection device for detecting needle stitches, and relates to the technical field of detection light sources. The detection method for detecting needle stitches comprises the following steps: obtaining a color image contrast ratio of needle stitches and an image background; disassembling the color image into R channel images, G channel images and B channel images; setting a significant threshold as a positive value; if the difference between the first contrast ratio and any one of the other three contrast ratios is greater than or equal to the significant threshold, then emitting red light through a light emitting assembly to illuminate the needle stitches; if the difference between the second contrast ratio and any one of the other three contrast ratios is greater than or equal to the significant threshold, then emitting green light through the light emitting assembly to illuminate the needle stitches; and determining that the needle stitches are more sensitive to one of the three colors of red, green and blue through the contrast ratio of the channel images of the needle stitches and the image background, and selecting the color of the light emitted by the light emitting assembly, so as to ensure the illumination effect.
