Multi-view Stereoscopic 3D Image Communication System for Web-based Reality Teleconferencing Application

摘要

In this paper, a new multi-view stereoscopic 3D image communication system for web-based real-time teleconferencing application is proposed by using the IEEE 1394 digital cameras, Intel Xeon server computer system and Microsoft DirectShow programming library and its performance is analyzed in terms of image-grabbing frame rate and number of views. In the proposed system, two-view images are initially captured by using the IEEE 1394 stereo camera. And then, this captured two-view data is processed and compressed by extracting the disparity data from them in the Intel Xeon server computer and transmitted to the client system through a communication network, in which the received 2-view data is reconstructed and basing on this data 16-view images are generated through the intermediate views reconstruction method for more natural 3D display in the client system. The program for controlling the overall system is developed based on the Microsoft DirectShow programming library. Some experimental results shows that the proposed system can display 16-view 3D images with a gray of 8bits and a frame rate of 15fps.
