High precision and multiple view point cloud data fusion is one of the bottlenecks in the blade measurement. A mechanical device of the multiple view point cloud data fusion using phase-measuring-profilometry was presented. A reference plane data rotating algorithm was designed

and the accuracy of three-dimensional blade data high precision fusion is (0.06±0.01)mm. The structure and method of the device are simple and practical with high efficiency and accuracy. Many blades can be measured simultaneously. It can thus replace coordinate measuring method.
