3D video with consumer cameras


While perusing our photos from the Hooptyrides, Inc. tour you may have noticed [Eric Kurland]‘s two handed stereoscopy rig. It’s constructed from two consumer grade Sony DV cameras. The problem with using two separate cameras to make stereo images or video is that a lack of clock sync will make objects appear out of their true position because of differences in framerate. To solve this problem Damir Vran?i? developed the 3D LANC Master. It reads the crystal frequency from one of the cameras and writes to the ram of the other camera using Sony’s LANC protocol. This constant monitoring keeps the clocks within +/- 3ms. The control box also has buttons to power on, zoom, and record in sync. The 3D LANC Master plans are completely open source and work with a large number of Sony cameras. We have more photos of Eric’s rig after the break.
