摘　　要：提出了一种新的由单幅二维投影图像确定目标三维空间方位的的方法,即在照、摄象机内部参数未知的条件下,采用目标上共面四线与他们在二维图像上投影相匹配的策略,来实现目标的定位;并将其应用于测距系统。因此该方法与以前方法相比,更附和实际需要,从而具有广泛的实际应用推广价值。This paper presents a distance measure system based on new method for determining the three-dimensional position and orientation of an object(relative to a camera)from a two-dimensional image.In contrast to the conventional approach,the method described here uses four coplanar lines on the object matching with their perspective image in the absence of the interior parameters of the camera.So this method has very important valu in the real application.
