3D data transmitting and displaying system with an omni-directional display for group learning

We developed a 3D data transmitting and displaying system with an omni-directional display for group learning. The omni-directional display system enables many users to watch 3D images from each viewpoint without wearing special devices. Therefore, we consider that the omni-directional display is an effective 3D displaying method in the environment of group learning. In our system, we reconstruct 3D shapes of objects from images which are captured by multi-viewpoint cameras. Next, we transmit reconstructed data to remote places and display on the omni-directional display. We realize a series of these process in real-time. Moreover, we implemented a PDA-based control user interface for the omni-directional display system, and realized the control freely from any positions around the display.
