3D-Coordinate Measuring System for Transit Automated Collimating

摘要

A light-weight and high-precision automatic 3-dimensional shape measurement system was developed. The system comprises an optical surveying instrument that has a built-in CCD camera, an image processor and a notebook size personal com- puter. Flat reflective targets with a circle mark are placed offset from selected points on the measurement object such as a section of a large structure before site installa- tion.
