Automatic evisceration is a very important production technology in the chicken industry. In this study, an automatic chicken eviscerating robot system was developed and evaluated based on machine vision for locating the chicken carcasses and anal incision. This system consisted of chicken carcass conveying device, robotic manipulator, end-effector, control system and machine vision system. Based on machine vision, this system employed color space conversion, threshold segmentation, morphological operation method and active contour algorithm to...
