-
摘要: 简要介绍了机载POS(position and orientaion system)系统视准轴误差检校的基本原理和方法,建立了相应的数学模型,利用实际航摄影像资料验证了视准轴误差检校模型的正确性和可行性,并分析了利用其实施对地目标定位的精度。Abstract: This paper simply introduces the theory and method of the boresight misalignment calibration of integrated GPS/IMU,and then a corresponding function model is established.Based on the test flight data,this paper not only validates the validity and the feasibility of the boresight misalignment model,but also analyses the accuracy of direct georeferencing by using the model mentioned above.
