摘　　要：采用人机交互方法按照一定顺序提取建筑物角点,根据近似点位进行角点位置的纠正,按照影像自动定向的结果计算模型的三维坐标,建立三维建筑物模型。实验证明,这一方法能有效地实现速度和逼真度的兼顾。特别是对于一些仅需小范围的建筑物建模场合,例如三维制导时的目标区域,采用该方法进行建模不失为一种简单而有效的方法。By man - machine intereommunion method, comer points of the building are extracted in order and the positions are corrected according to approximate points. Then, the image orientation is automatically processed and the 3D coordinate are computed according to the orientation result. The 3D building modeling is reconstructed. It is proved that the method of modeling realizes great balance of demand of speed and fidelity. It indicates that this 3D building modeling method is a simple and effective method especially in small building modeling areas such as the target areas when 3D homing.
