针对光电经纬仪红外相机测量系统动态测量精度低的问题，提出了一种通过修正各分系统之间延时时间从而提高动态测量精度的方法。首先介绍了光电经纬仪红外相机测量系统的组成和测量原理，分析了大地坐标系下物像空间的对应关系，指出了影响光电经纬仪红外相机测量系统的原因是相机内方位元素的准确性和光学畸变校正效果。分析了影响光电经纬仪红外相机测量系统动态测量精度的原因，提出了采用各分系统根据工作参数采用不同延时时间的误差修正方法。实验结果验证了该方法的正确性和准确性，标定结果与精度比对实验结果表明，经过动态测角修正的方位角与高低角测角误差均方根值分别由27.89"与17.67"提高到10.07"与8.56"，该方法有效地提高了动态测量精度，并且对其他光电测量设备具有参考价值。

In order to resolve the lower precision of optoelectronic theodolite dynamic measure precision, a method which is based on the correction of different delay time between the clock base and other sub-systems was proposed. The measurement theory and shipment of optoelectronic theodolite were introduced, the relationship between the object and the image was analysis. The reason which infects the precision were accuracy of camera inside azimuth element and the adjustment of optical distortion was pointed. And the reasons which effect the optoelectronic theodolite dynamic measurement were analysis, and the different delay time between different sub-system parameter were pointed. The correction and accuracy of the method were verified by test data, the average variance of optoelectronic theodolite dynamic error in horizontal and vertical were improved from 27.89"and 17.67"to 10.07"and 8.56". This method improves the dynamic measure precision of optoelectronic theodolite and is suitable for other optical electronic measurement system.
