3D anaglyph video systems are a low-cost technique to implement 3D imagingand can be applied in areas such as virtual reality, medicine, product design and visualization.The popular open source multimedia framework GStreamer, which is based on several plugins is widely used to handle multimedia data. This project proposes a modification of the videomixer plugin of GStreamerto implement the streaming of a 3D anaglyph video via the TCP/UDP protocol. This system is based on two BeagleBoard XM single board embedded device computers with Leopard Imaging cameras running Linux Angstrom OS and a PC running Linux. This systemwas implemented using GStreamer to send, receive, and blend left and right images. This design is based on different plugins and it will provide synchronization on various codecs to add functionality, like customization of the stream's audio and video components. The TCP/UPD protocol was used for communication between the embedded devices and the PC. Command pipelines were created to pass these commands to the GStreamer application to send and receive the data flow through the pipeline. This system generates a stereoscopic 3D video, achieved by encoding each eye's image using chromatically opposite color filters, such as red and cyan, and superimposing two images as a way to make the human brain combine them to visualize a single three-dimensional image. The implemented-three dimensional anaglyph system mixes the video dataand creates three-dimensional anaglyph video in real time.Finally, experiments were performed using real-time video streaming and static stereo images achieving the desired results.The implemented software is open source and is freely available for the research community.
