Sfm reconstruction
Web4 Dec 2024 · Figure 1 shows the flowchart of the 3D reconstruction process from images, called photogrammetry. SfM is a method that generates the sparse point clouds of 3D object shapes from images. The SfM process extracts feature points from images and calculates the correlation between the images based on feature point extraction. http://www.theia-sfm.org/sfm.html

In the alignment step, points are used to globaly move the reconstruction so that the observed GCP align with their GPS position. Two or more observations for each GCP are required for it to be used during the aligment step.
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.
