[courtervideo] shares an instructible with us on how to build a mirror rig to take stereoscopic pictures with one camera. We’ve had the thought “couldn’t you just do that with some mirrors?” when looking at a dual camera rig. Well, as we all suspected, you can. There are some advantages here, a single click gives you your 3d image or video without any post processing, and unless you just happen to have an extra camera lying around you can save money there. You do however lose some resolution compared to two separate cameras. This setup could actually add some steps if you were wanting to interlace your images for viewing on a 3d tv.
Who could forget the stereoscopic goodness of a View-Master? [Tuttle] put a modern flair on the classic optical device by adding two 1.5″ LCD screens. The screens replace the film disk of the original, showing slightly different images to produce a 3D effect. No word on a camera rig used to take the original images, but for our money this a great way to make something out of those useless key chain picture frames.
There have been a couple companies that have shown off full-sized 3D displays, but Fujifilm had a couple of products that caught my eye. The first was a stereoscopic camera called the Finepix Real 3D W1 that not only functioned as a 3D Camera, but also featured a glasses-free 3D display on the back. The camera was capable of using the separate cameras in different functions, allowing you to zoom one in, and take a wide angle with the other simultaneously.
They featured a miniature 3D display as well, which was the size of a regular digital photo frame but contained the same technology as the camera screen. As far as getting into hacking a 3D display, this would be a good place to start, though the ~$400 price might be a bit of a put off.
[Pyrofer] sent in his stereoscopic game project and we are just giddy with excitement. He has hacked apart an old TomyTronic 3D handheld viewer and put new guts in. He’s using a PIC micro to push stereoscopic imagery to twin LCDs. He wrote all code from scratch including the 3d library, wii nunchuck driver, and LCD driver. This thing even has bluetooth so he can play multiplayer if he ever makes a second one. The whole unit is kept alive via a lithium polymer battery so you don’t have to worry about any cords other than the wii nunchuck. This thing is awesome, we would love to play with one. You can see a video after the break.

[Gabriel] is making 3D movies using only one camera. This should be impossible because true 3D needs to be stereoscopic, with images from different perspectives for each eye. He’s worked this out by mounting the camera on a CNC gantry and programming it to make two passes along slightly different paths. He’s plotting the camera paths using SketchUp and a plugin that exports paths as CamBam files, automatically adjusting for perspective. The two videos are then merged using Stereo Movie Maker.
We’ve embedded both a 3D video as well as behind-the-scenes filming video after the break but you’ll need the red and blue 3D glasses to view the former. It’s not too much of a stretch to tweak his methods and use this for stopped motion video where one button press takes a frame for each eye. Now, who will be the first to bring us a Star Wars remake filmed in stopped-motion 3D using the original action figures? Continue reading “CNC used to make 3D video using one camera”
