摘　　要：近景摄影测量作为一种非接触性量测手段,其基本任务是通过数码相机(摄影机)获取图像信息,计算三维空间物体的几何信息以重建和识别物体。基于摄影测量原理,利用数码相机从不同方向拍摄物体使之构成立体像对,加之利用一定数量的控制点进行控制,即可实现小区域的三维物体空间重建。本文以未检校的数码相机对某浮雕进行外业摄影,并通过内业处理实现三维建模,验证该方法的有效性。As a non-contact measurement method,the basic task of close photogrammetry is to get the picture information through the digital camera,calculate the geometry information of 3D spatial object to reconstruct and recognize the objects.Based on the principle of photogrammetry,the digital camera is used to photograph objects from different directions to constitute a stereo-pair,a certain number of control points are also used for control,thus the 3D object space reconstruction of small area is realized.In this paper,the field photograph is taken for a relief with unchecked digital camera,three-dimensional modeling is achieved by indoor processing,the effectiveness of the proposed method is verified.
