RIT Center for Imaging Science

Abstract: Imaging Systems Development Lab (Pow)
July - August 2015

One way to make a 3D image is the use of red and cyan filters, and red-cyan 3D glasses. This is called an Anaglyph. The technology of anaglyph 3D images utilizes red and cyan filtered copies of the same image laid on top of one another, albeit slightly shifted. Once the viewer uses the glasses, the two filtered lenses cause two independent images to appear in the viewer’s brain with a slight offset which the brain interprets as depth to the image. The goal in this lab is to create a camera that takes anaglyphs on its own, without the need for external processing on an application such as Photoshop or ImageJ, and can have these photos exported via HDMI or USB and viewed using 3D glasses. The system will be based on the Raspberry Pi 2 computer system with Raspberry Pi cameras and fixed-focal length lenses (selected using a Pugh Analysis). The CamanJS system will use JavaScript code to process the images, while Python code will be the interface used to take the photos. The Python is also used as the user interface for the camera. The first objective is to make a working prototype. Although each Raspberry Pi system will require a separate power supply, the second objective is to integrate them using splicing/soldering so that only one power switch is necessary. The third objective is to have the camera be a prototype for a “do-it-yourself,” or DIY, camera. Further goals include adding audio and video functions to the camera,  so that the system could record 3D video (when using 3D red/cyan glasses to view the video stream). Although the end-result is designed to be merely a prototype, it can pave the way for future developments in imaging science.
