An approach for damaged region inspection and positioning in a flexible remanufacturing system is presented. The system is based on a welding robot and a measuring robot. A structured light vision sensor is mounted at the end of an industrial robot to serve as a measuring robot to obtain the 3-D surface data of damaged workpiece. The damaged region can be determined by the geometric alignment of a...
A robot based 3D measurement system is presented to overcome the disadvantages of coordinate measuring machine (CMM). As to calibrate the vision sensor in the system, a novel procedure that utilizes the robot to generate sufficient calibration points with high accuracy is proposed. The approach is based on a number of fixed points printed in a paper which is of low-cost. A multilayer perceptron neural...
A robot based 3D laser scanning system which a structured light vision sensor is mounted on the 6 degree-of-freedom robot is proposed to overcome the disadvantages of coordinate measuring machine (CMM). As to calibrate the vision sensor, a novel procedure that utilizes the robot to generate sufficient calibration points with high accuracy is proposed. An improved Tsai's method and a multilayer perceptron...
