Research on Dimensional Measurement Method of Large Parts

Abstract

Firstly, the size definition of large parts is given, and the importance of large-scale part size measurement methods is analyzed. Then, the existing large-scale parts measurement methods are studied, including large-scale three-coordinate measurement method, double theodolite measurement method, and laser. Tracker measurement method, indoor GPS measurement method and machine vision measurement method. The measurement principle, structure composition and research status of each measurement method are analyzed and summarized, and the SIFT image mosaic algorithm is introduced. Finally, the research and development trend of large-scale part size measurement methods is prospected.
