Structure from motion (sfm) is a computer vision technique that reconstructs the three dimensional (3d) structure of a scene from a set of two dimensional (2d) images taken from different viewpoints. The paper provides an overview of the available data and detailed information on the preparation of the different types of data as well as the process of connecting everything through annotations.

Imagine we have matched two keypoints, x 1, x 2 in two different images i 1, i 2 via a sift like feature matching pipeline. we are viewing the projection of the same 3d point x in both images. we now wish to identify the coordinates describing the location of x. It turns out that from this video, we can not only reconstruct the 3d structure of the artifact but also determine how the camera moved in 3d space during the capture of the video. the technique that makes all this possible is called structure from motion. This guide is intended as a resource for using structure from motion in research applications. it does not detail the algorithms or mathematical background of the methodology, but rather how to use it in practice.

As described in the previous step, the 3d scene structure (i.e., the sparse tie point cloud) and camera motion (i.e., the camera’s positions and poses) are determined in an arbitrary coordinate system with unknown units. For each image pair (parallelly): match the first h (subset size) features of the two images. if the number of matches from the subset is smaller than th (expected number of matches), return and skip the next step. do regular matching and geometry estimation. Given two or more images (or video frames), without knowledge of the camera poses (rotations and translations), estimate the camera poses and 3d structure of scene. We assess the accuracy of structure from motion/multiview stereo (sm) terrain models acquired ad hoc or without high resolution ground control to analyze their usage as a base for inexpensive.
