Derong intelligent vision guidance system obtains the coordinate parameters of the feature holes (round holes, square holes, waist holes, etc.) of the parts through the self-developed vision sensor, compares the theoretical data of the three-dimensional digital model of the parts, and then uses the PNP algorithm to accurately locate the three-dimensional attitude of the parts (XYZ/RxRyRz), so as to guide the robot to complete the loading and unloading work; As large as the roof and side circumference, as small as the threshold, B-pillar and other small size parts, derong Intelligence can provide stable and reliable solutions, saving the cost of making and maintaining high-precision material boxes, pallets and other high-precision parts carriers, improving the flexibility of the production line and improving the production efficiency.
