| 摘 要： | 由CCD摄像机和光学镜头组成对二维平面内的几何量测量的装置,由于光学镜头存在畸变误差,使测量精度受到影响。为了实现面内几何量的高精度测量,采用平面靶对面内几何量测量装置进行标定,建立物面与像面的投影关系,实现对平面内参数的精确测量。

| Abstract: | The two-dimensionaI geometric measurement device composed by a CCD camera and opticaI Iens.Because of the opti-caI Iens distortion error,the measurement accuracy is affected.In order to achieve the high-precision measurement of the two-dimensionaI geometric,in this paper,the measurement device is caIibrated by a pIane target,the projection reIationship between the object pIane and the image pIane is estabIished.Then,accurate measurement can be achieved of the parame-ters in pIane. |
