An Effective Method for Fast Hub Location Based on Design-Template
In order to solve the hub workpiece recognition,location and precision grabbing problem before fine processing,a method of hub workpiece recognition and location based on design-template is proposed.In this method,create design-template according to the design size and external shape of the hub workpiece,extract some invariants as features,obtain similarity according to the corresponding features recognized and extracted from target image,adjust and align the image in small range based on the smallest similarity criteria,then achieve target location.Experiments show that this method can precisely locate the key parts of the hub workpiece and the recognition accuracy is greater than 98%,error accuracy of the position and angle,respectively,are within 2 pixels and 0.08 degrees,moreover it has less amount of calculation.It could satisfy the actual need of production line.
