摄影测量法（英文：Photogrammetry）是一种利用被摄物体影像来重建物体空间位置和三维形状的技术，它的历史和照片的历史相当，可以上溯到19世纪中叶。

摄影测量法应用于多个领域，除了被考古学家用于快速绘制大型和复杂建筑遗址的详细地图以及被气象学家用于测得龙卷风的实际风速外，它还可在地形图绘制、建筑学、工程学、生产制造、质量控制、警方侦察和地质学等方面发挥效用。在电影的后期制作中，摄影测量法也被用于将演员的真实动作融合到计算机虚拟场景中。

Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. Moreover, it may be used to recover the motion pathways of designated reference points located on any moving object, on its components and in the immediately adjacent environment. Photogrammetry may employ high-speed imaging and remote sensing in order to detect, measure and record complex 2-D and 3-D motion fields (see also sonar, radar, lidar, etc.). Photogrammetry feeds the measurements from remote sensing and the results of imagery analysis into computational models in an attempt to successively estimate, with increasing accuracy, the actual, 3-D relative motions within the researched field.
