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。
The use of a single image to measure the aircraft’s position and attitude parameters has been widely used in flight tests. Based on the collinear equations of classical photogrammetry, a new method of solving the position and attitude parameters based on single image is proposed. The method avoids the problem of “correspondence” in the body coordinate system and the world coordinate system by using the “bridge” -photo coordinate system to transform the problem into the image point of the fuselage mark point Coordinate and the coordinates of the body of the corresponding computing relationship. Experimental results show that this algorithm is correct and effective. It has incomparable advantages in some situations that are not suitable for installing multiple cameras, which not only saves manpower and material resources but also improves work efficiency.
