基于彩色摄像机的三维物体双投影测量法

Double Projecting Measurement Method of 3D Object Based on Color CCD

通过对三角测量法的分析比较 ,提出了双投影三维测量法 ,它采用彩色 CCD,一次性获得三维物体两个侧面的三维数据 ,不仅测量速度快 ,而且能有效解决一般三角法的阴影和遮挡问题 ,并可以提高测量精度 。

The paper discusses the shadow area and occluded area occurring in triangularmetry,then advances the double projecting method for 3D object measurement.The new technique dased on color CCD using only one projector and one color camera,can not only avoid the shadow area and occluded area which are fatal defect of trangularmetry,but increase the measurement precision and speed.It can simplify the structure of measurement system,and be easy to miniaturize the instrument.
