insight3d let’s you create 3D models from photos. You give it a series of photos of a real scene, it automatically matches them and then calculates positions in space from which each photo has been taken along with a cool 3D pointcloud of the scene.

MicMac is a free open-source (Cecill-B licence) photogrammetric suite that can be used in a variety of 3D reconstruction scenarios. In aims mainly at professionnal or academic users but constant efforts are made to make it more accessible to the general public.
OpenSfM is a Structure from Motion library written in Python. The library serves as a processing pipeline for reconstructing camera poses and 3D scenes from multiple images. It consists of basic modules for Structure from Motion (feature detection/matching, minimal solvers) with...

Open-source application for Structure-from-Motion/Multiview Stereo/Synthetic Aperture/Photogrammetry fused depth maps with KWIVER algorithms. Uses metadata from GPS & IMU sensors or image/video keyframes. Estimates camera parameters and 3D landmarks.
