摘要:: 为了降低成本，在简易设备上实现多视点下三维数据的融合，文中提出了一种简单易行的工作台旋转角度测量方法。人们知道消影点v反向投影成方向为d的射线，消影点口仅依赖于该射线的方向d，而与空间点的具体位置无关。所以可以通过计算消影点来求解工作台的旋转角度。该方法具有较高的计算精度，对系统的要求低，易于实现。把该方法应用于结构光的三维重构中，实验结果表明计算精度能满足三维数据融合的要求

Abstract:: To reduce the cost and realize 3D data fusion from different view- points with facile facilities,an easy and practical method of measuring angle is presented. As we know, the inverse projection of vanishing point v is a radial whose direction is d . The position of point v only depends on the radil＇s direction d , while has nothing to do with the position of 3D dot. So we can measure the angle of revolving tttmtable by solving the vanishing point. This method possesses high precision with leas accurate measurements, and is easy to be implemented. When it is used in 3D reconstruction by structured light, the experiment result shows the precision fits the needs of 3D data fusion
