摘要：

To achieve high-precision and non-contact measurement of outer and inner surface defects on hemispherical shell, a optical composite measurement method was proposed on the basis of a new type of non-orthogonal coordinate measuring machine. It combined the laser probe's point-scanning with the vision probe's surface-scanning, and could measure not only the coverage and distribution of the surface defects, but also their depth/height. Actual measurement results show that the method is feasible, precise and efficient.
