提出了一种全新的非接触式三维复杂曲面测量方法，利用片激光源产生的光切面在被测物表面形成一个封闭光带，并使光带同时成像在3个互成固定角度的CCD摄像机中.经过CCD摄像机像面和光切平面之间的空间映射变换及图象处理后,可一次获得被测物的某一个截面的二维轮廓信息.随着测量系统以固定的间距沿垂直于光切面的方向步进测量，最终以被测物表面的大量离散点数据非常近似地获得了整个被测物的三维曲面信息.%A new measurement method of 3-D complicated curving surface was proposed. A closed light strip on measured object was formed by laser sheet illumination. Images were attained through three CCD cameras. 2-D figure information of any section was also attained after spatial mapping transformation between CCD image plane and light-section plane. Eventually, the 3-D curving surface information of measured object was obtained in the form of discrete data through stepping measurement along the direction vertical to light-section plane.
