摘要
IMU/GPS信息作为外方位元素先验值加入到相对定向的平差中,形成了新的相对定向方法———带约束条件相对定向。在一般相对定向的基础上论述了带约束条件相对定向的原理和相关权值的取法,并且通过模拟实验和飞行实验数据来验证带约束条件相对定向的优越性。
This paper presents a new relative orientation method, which uses the IMU/GPS measurements as a priori constraint. In comparison with the traditional method, the new one combines two kinds of information： stereo conjugate points and direct measurements of the exterior orientation elements. Therefore, how to choose the weights between these two sources of information becomes a discussion topic. Both simulation and practice experiments show that the new method has low error sensitivity, which is its superiority over traditional method.
