一种基于运动的线结构光视觉测量系统标定方法
A Calibrate Method of Line Structured Light Visual Measurement System Based on Motion
摘要
Abstract
A line structured light visual measurement system based on Cartesian-coordinate robot was proposed for three-dimensional digital measurement of hull block. By controlling robot motion, line structured light visual sensor installed on the robot terminal captured images of stable planar target and the pose transformation parameters between camera coordinate system and robot coordinate system were calibrated. At the same time the feature point coordinates on the planar target were achieved with cross ratio invariability theory, then structured light parameters was calibrated. By measuring experiments of known standard parts, the easily realized method is proved efficient and can meet the precision requirements of digital measurement system for hull block.关键词
