| Stereoscopic video gradually came to our life ,it became the trend for modern video technology and a focus of research. Compared with traditional two-dimensional video, Stereoscopic video added depth information, thus increasing the visual sense of reality .The transmission of stereoscopic video by network involved two or more perspectives, a relatively large bandwith is needed. With the development of stereoscopic video and network technology, network-based stereoscopic video transmission is possible, which would have a broad application prospectsThe content of this research came from the 863 project“high-frequency wireless communication data service demonstration platform”which aim at building a system that can realize the acquisition of stereoscopic video and data sending. The main task of this paper is as follows:1.The implementation of multi-view stereoscopic video capture side. Proposed a capture program with the speed of 800,400,200,100Mbps, which meet the demands of task switch. According to the demand of stereoscopic video shooting, selected the Point Grey FlyCapture Flea2 as the capturing device, completed the development of Point Grey Flea2 SDK, set the camera’s saturation, white balance, and other parameters. The multi-rate switch need a video format conversion, raised a YUV422 YUV420 conversion methods which can realize distortion-free video conversion.2. The implementation of multi-view stereoscopic video transmitter. Built a Gigabit LAN from the basic theory of computer networking, which provide a hardware environment for the high speed transmission. Using UDP and multi-thread for network programming to complete stereoscopic video transmission. Several ways to optimize network speed is introduced to meet the high speed need. Thread synchronization is used in the program to achieve synchronization of the video sender. |
