激光扫描中平面拟合及坐标转换模型构建
Plane Fitting and Transformation in Laser Scanning
摘要
Abstract
Coordinate transformation is often encountered in surveying and mapping, such as the conversion between local system and global system, conversion among sensors and so on. Common points used for coordinate transformation in traditional ways were replaced by a series of planes, and a coordinate transformation model was built based on planes. Here, a normal definition of plane was given, and a robust fitting method for plane was put forward. Plane-based coordinate transformation model was constructed and the calculation method of parameters was deduced. At last a group of simulated data was used to prove that this model is in a correct way.关键词
