Abstract: Methods and apparatus for three-dimensional (3D) camera positioning using a two-dimensional (2D) vanishing point grid. A vanishing point grid in a scene and initial camera parameters may be obtained. A new 3D camera may be calculated according to the vanishing point grid that places the grid as a ground plane in a scene. A 3D object may then be placed on the ground plane in the scene as defined by the 3D camera. The 3D object may be placed at the center of the vanishing point grid. Once placed, the 3D object can be moved to other locations on the ground plane or otherwise manipulated. The 3D object may be added as a layer in the image.
