Guys,
I have an interest in Stereo Photography. The technique has been around since Charles Wheatstone's clever idea in 1838 so not new. Bringing this up todate turns out Dr. Brian May of Astronomy and "Queen" fame is also an advocate, see https://www.londonstereo.com/.
I have two cheap cameras set on a frame and set just wider than the gap between the average human eye and I take a photo pair by pressing the two shutter buttons as near at the same time as I can. Current processing is simply copying Left/Right images to Left/Right directories then assembling image pairs using Python/OpenCV into paired Sterogram images and view them on a screen using a home made Stereogram viewer made from a pair of cheap +3.5 reading glasses. All good.
One current thought is to process the Left/Right images into an animated GIF but presenting this needs the GIF player to sync to frame rate or at least match it. I've investigated Stereo TV projectors and matching glasses but their frame rate starts up around 90frame/sec and goes up. These use a various syncing method including a sync frame of all white which is then blocked for both eyes.
What I would like to do, and the point of posting here, is present my Left and Right image pairs full screen on alternate frames using a Pi and to view the composite image via/through left and right LCD shutter panels (found some on the Pi Hut site) synchonised to the frame rate from a signal output from a GPIO pin. Yeah, maybe not as simple.
I invite comments/ideas.
