Measurement Method Based on Grating Projection for Surface Reconstruction

Liu Da-feng Liao Wen-he Dai Ning Wang Zhen(College of Mechanical and Electrical Engineering,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,Jiangsu,China)  
The measurement of scattered point cloud data is the foundation of surface reconstruction of a 3D object.This paper analyzes the principle of 3D measurement and proposes a novel 3D measurement and calibration method based on the grating projection by adopting the technologies of Gray code and phase shifting.A code-revising algorithm is also developed to deal with the error possibly caused by the image noise during the decoding process.The proposed measurement method possesses the advantages of both Gray code and phase shifting,so it is of simple co-ding,large measured range,strong jamming resistance,high resolution and good suitability for the object with continuous surface in small range.Experimental results show that the proposed method is of good practicality and stability because it may result in regular scattered point cloud data with high quality.
