An Integral Projection Approach to 3D Rigid Body Transformations

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. Key areas in this context include Structure from Motion, Motion from Structure and Camera Calibration. This paper introduces a new approach to analyse 3D rigid body transformations which we call integral projection. In this model, we are able to use frequency domain information to estimate parameters of the transformation. Simulations are presented which demonstrate our initial successes
