SfM(Structure from Motion)简介
Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene.
Structure from Motion(SfM)（从运动图像中恢复三维结构），是一种从可能带有本地运动信号结合的二维图像序列中预测三维结构的摄影测量序列图像技术。它在计算机视觉和视觉认知领域有研究。在生物视觉中，StM指的是人（或者其他活着的生物）可以从一个运动物体或场景的投影的二维运动领域恢复三维结构的现象。
