摘　　要：针对地球曲率对光学设备测角数据的影响,在深入研究现有测角数据地球曲率修正模型的基础上,提出了基于坐标旋转变换法研究新思路,建立了地球曲率修正精确模型。通过对新模型的讨论分析和与以往模型进行对比,结果表明可有效提高光学设备的测量精度和测试布站的灵活性,特别适用于光电经纬仪和宽视场光学设备高仰角测量时高精度数据处理。As the earth curvature has an effect on optical equipment angular measuring data, a new method of coordinate rotation transformation was put forward and a precise correction model of earth curvature was built up based on research on existing correction model. The resuits prove that the model can better improve optical equipment measuring accuracy and testing station layout flexibility than the existing model. The model is especially suitable for data processing with high precision by high elevation for electro-optical theodolite or wide view optical equipment.
