摘要
分析了用光学ＣＴ原理构成无透镜光学遥测垂线坐标仪的结构特点．提出了处理垂线光学投影数据的自卷积算法以及从多个方向投影数据提取垂线坐标的代数反演算法．
In this paper an analysis of the structural characters of the optical remote pendulum wire coordinator is presented which works on the principle of optical CT without lens. An autoconvolution algorithm is established for the processing of the optical projection data of the pendulum wire, and an algebraic inversion algorithm is given for the extraction of the coordinates of the pendulum wire from the multidirectional projection data.
