摘要 大空间坐标测量网络主要由若干测量基站组成,为在测量现场完成网络的构建,并在测量过程中实时重新标定测量基站的空间坐标,通过对网络的测量原理及测量基站的结构进行分析,提出了模拟基站的标定模型。该模型将球形标靶作为模拟基站,并将模拟基站布置在特定位置上,可解决共面布局下测量网络的标定问题。为获取标定模型所需的距离信息,提出了主动扫描和寻心扫描两种瞄准测距方法。仿真标定实验结果表明,当测距精度为0.5 mm时,测量基站的坐标标定误差均值为2.1 mm。瞄准实验结果表明,两种瞄准方法所得测距值标准差分别为0.16 mm和0.34 mm,与测距精度相当。

Abstract:Large scale coordinate measuring network mainly composed of a plurality of measurement stations. In order to build the network in the field of measurement, and re-calibrate the measurement stations coordinates in measuring, the simulate-station calibration model is proposed following the analysis of the networks working principle and the measurement stations structure. The model takes the spherical target as the simulate-station which is arranged in a specific position. It can solve the calibration problem of the measurement network under coplanar layout. In order to obtain the distance informations required by the calibration model, two kinds of aiming methods, active scanning and center searching scanning, were proposed. The simulated calibration experiment results show that when the ranging accuracy is 0.5 mm, the mean coordinates calibration error of the measurement station was 2.1 mm. The aiming experiment results show that the standard deviations of ranging values obtained by two kinds of aiming methods were 0.16 mm and 0.34 mm. And they were roughly equal to the ranging accuray.
