In this paper we made a systemic analysis and study of the accurate orientation technology in the process of helicopter landing - photogrammetry , made the model of using double ccd to measure the exact position of helicopter based four latent points photogrammetry , educed formula about beaconing position , analyzed the computing error , and particularly computed the information of beaconing position of the helicopter ' s landing by experiment emulation . in the result , the error between a computed value and a measurement value was less than 5 centimeters
本文对直升机着舰精确定位技术中的摄影测量算法进行了系统分析和深入研究，在四特征点测量算法基础上建立了双ccd摄影测量直升机精确位置坐标的数学模型，进一步从各个影响算法测距精度的方面讨论了计算误差，推导出测量信标坐标位置的计算公式，并对利用双摄影测量算法计算直升机着舰挂钩位置的正确性及准确性进行了模拟实验，得到的算法计算值和实验测量值之间的误差在5cm以内。
