In general, to reconstruct the accurate shape of buildings, we need at least one stereomodel (two photographs) for each building. In most cases, however, only a single non-metric photograph is available, which is usually obtained either by an amateur, such as a tourist, or from a newspaper or a post card. To evaluate the validity of 3D reconstruction from a single non-metric image, this study analyzes the effects of object depth on the accuracy of dimensional shape in X and Y directions using a single non-metric image by means of simulation technique, as this was considered to be, in most cases, a main source of data acquisition in recording and documenting buildings. 展开更多

DLT(Direct Linear Transform,直接线性变换)广泛应用于非测量影像的处理中,但是其在控制点不足的情况下,精度难以保证,本文以此为切入点,附加共线约束,保证了直接线性变换的精度,并以建筑立面彩色点云获取通过实验进行了验证。
