[0062] The visual-based detection method and device for steel ball surface defects of the present invention will be described in detail below in conjunction with the embodiments and the drawings.
[0063] In the vision-based detection method and device for steel ball surface defects of the present invention, the sorting machine uses two industrial cameras to simultaneously collect steel ball surface images, and the collected images are processed in real time in the PC to determine whether there are defects. The PCI acquisition card connected to the PC sends control commands to realize template image acquisition, real-time acquisition of steel ball images, steel ball queue stepping, steel ball sorting and sending to the sorting box.
[0064] Such as figure 1 , figure 2 , image 3 As shown, the vision-based steel ball surface defect detection device of the present invention includes a workbench 4, and the workbench 4 is provided with a light source 5 composed of a light source bowl c...
