Research on Data Acquisition Method of Characteristic Lines Based on Reverse Engineering

This paper researches on the data acquisition method in reverse engineering based on coordinate measuring machine. Firstly, it puts forward the data acquisition method of characteristic line based on the principle of path planning, then, it summarized the application scope of characteristic-line method by analyzing the examples of data acquisition of regular surface and free curved surface products, finally, it realizes the rapid data acquisition of product based on coordinate measuring machine.
