Backlight Panel Size and Contour Detection
Size and contour inspection software for tablet backlight panels after assembly, where dimensional inspection is difficult. After tilt correction, feature-region extraction and character gray-value adjustment, an adaptive-threshold method based on gray-density distribution and gray difference traverses the feature regions as sub-images, merging overlapping defect sub-images and filtering out regions without obvious defects. A multi-class support vector machine then identifies the backlight-panel defect types, trained on the pixel-distribution patterns of the binary images.
