摘　　要：提出一种相机定向方法。在透视投影和坐标变换的基础上,应用靶标与其像点的单应性,建立靶标坐标系与摄像机坐标系之间的转换关系,从而确定摄像机在靶标坐标系中的姿态、位置,通过在三坐标测量机上的实验表明该定向技术的正确性,该技术在相机定向领域有一定的实用价值。A method of camera orientation is introduced. Based on the perspective projection and coordinate transformation, the relationship of target coordinate system and camera coordinate system is established on the homography of the application target and its image point. Then the position and orientation of camera is computed in the target coordinates system. The experiments in the coordinate measuring machine shows that the technology of camera orientation is correct and of the certain practical value.
