Abstract
In this study, a computer vision-based identification system is established for the detection of cracks on mobile screen. By using a CCD (Charge Coupled Device) industrial camera, images of mobiles’ screen on the industrial assembly line are obtained. For each mobile, the CCD industrial camera is revolved from several different viewing angles during detection of the mobile to avoid that cracks cannot be detected from specific viewing angles. Then the obtained RGB model images are converted into HSI color format. According to the obtained hue and saturation values, this system could accurately and effectively identify both large and tiny cracks on mobile screen, which demonstrates the validity of the machine system. This system could help modern industry for fast and effective cracks detection on mobile screen.
