视觉测量中一种平面标定新方法

A New Plane-Corresponding Method for Based Camera Calibration in Vision Measurement

测量用摄像机进行标定是视觉测量中的重要环节.在分析其他标定方法的基础上,提出基于平面的标定方法以及它的应用场合、精度分析等.此平面标定法完全能满足一般应用场合中快速、准确的测量要求,尤其适用于实时性要求较高的几何尺寸在线检测.当摄像机镜头畸变较小时,应用此线性标定方法可以达到与非线性标定同等的精度.

Camera calibration is the most important part in vision measurement. This paper reviews some of the founder techniques recently reported in literature. The paper is organized as follows: There are some math models calibration, such as the matter-image corresponding model, CCD figuring model, etc. The new plane-corresponding method for calibration is described. Application of the calibration method in the non-touch measurement is shown. The theoretical precision of the model is analyzed. Some important experiment data are shown. Finally the concluding remarks are given.
