Study of Pairing Vision Measurement in Iarge-scale Section
Author(s): 
Pages: 289-291
Year: Issue:  2
Journal: Computer Measurement & Control

Keyword:  大尺寸截面视觉测量传感器对校准坐标测量臂;
Abstract: 根据大尺寸测量系统的现状,从分析线结构光人手,提出了组建传感器对测量方法,使每对传感器具备差动测量能力,提高单点测量精度;利用坐标测量臂和激光跟踪仪的大尺寸测景能力,对传感器坐标系进行全局校准,提高校准的精度和效率;研究椭圆检测算法,提出利用椭圆平行弦中点连线必过椭圆中心基本定理,求出椭圆中心坐标,拟合出椭圆形状;通过理论分析,该方法切实可行.
