MatchMover provides you with a set of objects called 3D primitives. 3D primitives are basic 3D shapes such as cubes, cones or spheres. You can import other objects into MatchMover as long as the object s are in the OBJ format. You can use a 3D object as it appears or edit it, using one of the MatchMover’s manipulator tools. These virtual objects are fixed in space, and rendered using the estimated camera parameters. The process is successful when the motion of the virtual objects in the composed sequence is consistent with that of the real scene. You can also use 3D objects to define survey points mapping by dragging the mouse from one vertex to the image plane. See Setting survey points using elastics.
