摘　　要：POS辅助航空摄影测量中会存在视准轴误差和空间位置偏心差,其会对最终结果精度产生较大的影响,传统的飞行检校方法存在耗费大以及对天气、空域等因素的要求高等特点,不方便进行经常性检校工作。本文提出了一种基于地面检校场的检校方法,并详细推导出误差解算数学模型,同时利用建立好的地面检校场设计试验,最后的试验结果证明了该方法的正确性。The final results of the POS-supported aerial photogrammetry will be affected by the boresight alignment and lever arms. The high cost and high request for many factors such as weather and airspace are existed in the traditional flying calibration meth- od, which makes the calibration difficult to be went ahead often. A calibration method based on the built-ground calibration field was proposed in this paper, and also the error calculated mathematic model was deduced in detail. The experiment designed on the built- ground calibration field showed the validitv of the method.
