Abstract :
We propose a method to generate a wider Field of View (FOV) using multiple RGB-D cameras. In the initialization step, we extract the matched feature points from the moving object in order to calculate the transformation matrix. Then, the depth data would be aligned using the transformation matrix in the world coordinate system. The wider FOV is generated after the perspective projection. The results show that two input depth images can be correctly combined into a wider depth image.
