Coordinate Transformation of Laser Tracking in-Site Measurement System for Big Gears
An in-site measurement method for big gears based on laser tracking and coordinate measurement technology is proposed in this paper. The coordinate transformation method, in which direction cosine are used as parameters, is suitable for large rotation angle transformation. The coordinate transformation with large rotation angle in the in-site measurement, hence, can be realized. The experimental results show that the proposed coordinate transformation method has the advantages of high accuracy and stability, and can meet the requirements of the laser tracking in-site measurement system for big gears.
