Abstract
In the three-dimensional measurement, when the data are processed, the alignment of point clouds with CAD model is an indispensable step. Only by this alignment can the CAD model coordinate system be consistent with the measurement coordinate system, therefore, the measured values have comparability. An in-depth study has been carried out on the alignment methods and techniques according to CAD model and point clouds in CATIA, and a series of alignment methods and techniques have been provided, such as compass method, aligned sphere method, vector matching method, etc. For complex CAD model alignment, one or several appropriate ways can be chosen to achieve alignment work after actual measurement, in order to improve the alignment accuracy. These methods and techniques, for data processing work of digital three-dimensional measurement, have some practical engineering guidance significance.
