Technology to automate construction of visual-inspections programs for production-lines
Fujitsu Laboratories today announced that it has developed a technology that automatically generates visual-inspection programs that use images to automatically detect part-mounting and surface defects on production lines for electronic devices. Existing technologies for automatically generating image-processing programs work by recognizing certain geometric primitives, such as straight lines and circles, and recognizing the positions of assembled parts. Fujitsu Laboratories has built on this technological base and developed two new technologies. The first technology is trained on the method for comparing against pre-registered images of parts with complex shapes and the whole board, and then applies the comparison method against images captured on the production line to recognize when parts are out of alignment. The second technology identifies part defects by recognizing a variety of image features, including brightness and line orientations, in the patterns of parts images and making accept/reject decisions.
