摘要：Today we are up against the puzzle that how to acquire the 3D information of city efficiently and quickly. Many researchers distributed all over the world put forward different methods towards their own applications, but there is still lack of a approach which can meet most demands from various users. In this paper, we design and implement a 3D reconstruction method of city buildings from single UAV(Unmanned Aerial Vehicle) image. As a new platform of Remote Sensing, UAV has many good characteristics such as low cost, simple manipulation, high resolution, flexibility and etc, so we choose it as the tool for city image acquisition. We can extract both geometry and texture information from UAV images. In a single UAV image, at first we get the inner elements (x 0 , y 0 ) and f by checking up the camera, secondly we divide the parallel lines in buildings into three groups which parallel X, Y and Z coordinate axis respectively and compute the three joint points based on related photogrammetry theory, thirdly calculate the three angle elements A, and to implement the image relative orientation, fourthly compute the scale between reality and image using the real coordinate information drawn from 2D GIS databases, then on the basis of all the above parameters we can measure the real height of buildings and reconstruct their 3D models. In the paper, we have also build some accurate models to test the feasibility and practicability of this method
