An Integral Projection Approach to 3D Rigid Body Transformations [PDF]

, 2004
The analysis of 3D rigid body transformations based on camera images is of great significance in many research areas. Classical methods to recover 3D object information often use a set of cameras that cover a static scene from different view angles.
