| 摘 要： | 本文主要是对以CCD技术和CT技术为基础的GYC-500型光电遥测垂线坐标仪的进一步改进，偏重于数据处理，即对该仪器现场实测资料数据失真的恢复处理和分析，基于垂线坐标求解的物理意义，在光学CT反演算法中，结合现场数据的疏密特点，剔除了干扰所带来稀疏的非正常数据，使得参与最小二乘法的直线为真值，从而得到了垂线的正确位移，并与人工观测的数据比较而论证了数据处理方法的正确性和合理性。GYC-500仪器采集的数据经过该方法处理能得到与实际相符的测量结果。

| Abstract: | This paper describes the improvement of GYC-500 photoelectricity telemetry perpendicular coordinate instrument which is based on CCD and CT techniques, emphasizing particularly data-processing. The comeback and analysis of locale measuring data are discussed according to the physical meaning. In optical computer tomography inversion algorithm, eliminating bad-data and using real straight line to getting pendulumn wire projection coordinate data. Last demonstrating the correctness and rationality of data-processing method. By this method, data of GYC-500 is consistent with artificial measuring data. |
