An industry robot and external axle scanning system is designed for medium-sized complex workpiece measurement and reverse engineering. An industry robot, which carries a structured light vision sensor to sample data, serves as main data sampling actuator. A workpiece is fixed on an external axle, and any part of it can be scanned on rotated place. The spatial location relationships of the robot,...
Shape from shading (SFS) is an important method for such fields as surface measurement of an object. In order to improve the SFS 3D reconstruction accuracy, utilizing the fact that artificial immune optimization and particle swarm optimization algorithms can compensate for each other, a reconstruction method based on a hybrid immune particle swarm optimization algorithm is proposed in this paper....
To solve the related problems of a robot 3D scanner, an external axle is added into the scanning system so that the scanning path is simplified obviously, work range is enlarged and scanning accuracy is improved. Some key points such as the kinematics model of the system, stripe light sensor model, hand-eye calibration and robot-external axle calibration etc. are discussed. The feasibility of the...
