【Abstract】 To solve the problems of the speed and the accuracy in free-form surface measurement, an automatic measurement system based on conoscopic holography is proposed. With a 5 DOF automatic positioning system, the system can realize accurate and efficient measurement of free-form surface according to the 3D information of the component’s CAD model. The principle of conoscopic holography is introduced, and the measurement system is described. Inspection planning based on CAD model and optimized method are discussed, and measurement experiment is presented.更多还原
