摘要
本文研究了获取物体表面三维信息的主动式方法-编码光栅法(CLP),并提出了用于CLP的定标方法.该方法分为两步,先用DLTEA算法对摄像机进行定标,然后通过线性方程计算光栅平面在三维空间的参数,而不象传统的主动式方法那样,由非线性方程计算三角测量关系中的角度、距离等参数。因而该方法计算简便精度高,也适用于其他类型的主动式方法。理论分析和实验表明,CLP方法具有简单、实用、能快速实现三维信息的获取等特点.
This paper investigates an active approach of range data acquistion-Coding Light Patterns
(CLP) and presents a new calibration algorithm for CLP. The camera calibration are solved by DLTEA
algorithm and the calibration with respect to the coding light pattern are solved by determining a series of light
plane parameters rather than the traditional triangulation parameters.This calibration algorithm can be easily ex-
tended to other active approaches of range data finding.Theoretical analysis and experiments state that the CLP is
an accurate, fast and efficient approach for obtaining 3D information of object surface.
