点云数据的二次曲面几何测量方法
Quadric Surface Geometry Measurement Method for Point Clouds
摘要
Abstract
Geometry measurement based on point cloud is an important non-contact measurement method.A quadratic surface geometry measurement method was proposed based on undetermined co-efficients for point cloud data.A unified framework for solving quadratic surface (including spherical, cylindrical and conical surface)was established.According to the quadratic surface equation and the different types geometric parameters of quadratic surface,the solving methods for the specific geomet-ric parameters of the spherical,cylindrical and conical surface were implemented.Experimental re-sults show that the method can measure the desired geometric parameters from point cloud data quick-ly and accurately,and it is a practical and feasible method.关键词
