摘　　要：针对数码相机定位问题,根据透镜成像原理确定实物与像之间的几何关系,合理设置实物与数码相机的相对位置关系,即角度和距离。采用映射几何建立参数方程模型,求得靶标上的圆心在相机像平面的像坐标。According to the principle of lens imaging, the geometry relations between a practicality and its picture are confirmed. We set up two parameters of angle and distance to describe the relatively position of the practicality and lens imaging. Using the theory of mapping geometry, we constitute the Parametric Equation Model to get the picture coordinates in the picture plane of the center of a circle from the drone.
