摘　　要：利用单幅影像测量飞机的空间位置和姿态参数在飞行试验中有着广泛的应用。在经典摄影测量共线方程的基础上,提出了一种新的基于单幅影像求解位置和姿态参数的方法。该方法回避了机身标志点在机体坐标系与世界坐标系中的"对应"性问题,利用"架桥"——摄影坐标系,使问题转化为机身标志点的像点坐标与机体坐标的对应运算关系。试验结果表明,此算法正确有效,在一些不适合安装多台摄像机的场合有着无法比拟的优势,不但节省了人力和物力,还提高了工作效率。It is widely used in flight test for measuring position and attitude using a single plane image. A new method for solving orientation and position based on a single image is proposed, which is on the basis of the classical photogrammetric collinearity equation. ＂Bridging＂, the photography coordinate system, was used in the method to avoid the ＂corresponding＂ problem of the feature points between the body coordinate system and world coordinate system, and translate the problem into the corresponding operations relationship for the feature points between the body coordinates and image coordinates. The results show that the method is correct and effective, and has incomparable advantages in some situations where it is not suitable for installing more cameras.
