Meshroom is a powerful open-source tool for creating digital replicas of your film set, complete with tracked camera. Move beyond simple camera tracking with geometry of your entire scene, ready to receive shadows, line up CG objects, add defocus effects, and visualize your entire scene in your favorite 3D environment. Note: The survival guide includes demonstrations on how to check the results in Maya and Nuke, but knowledge of these apps isn't necessary to work with Meshroom. You can use any 3D-capable application (including the free, open-source Blender) to perform the same tests.
