A 3D Mounting Rig for two Sony Digital Cameras Prof. John Hart Program in Atmospheric and Oceanic Sciences University of Colorado Boulder, CO 80302 Mar. 1, 2005
Version 2 - no camera clips required. Variable base via sliding left camera in guide slot. Alignment by precision machined back ridge that sits against the base plate of the camera. Separation is about 3.2 to over 5 inches.
Tilt adjust to compensate for inverted angular displacement. Once calibrated, not need to change in the field (unless you drop it or something). Cameras attach via easy to operate thumbscrews. Bracket weight is about 6 ounces. Includes tripod socket (under the LANC controller). The advantages of shooting with an inverted horizontal mount are that you get the closest possible separation with the landscape planform. This orientation is best for projection and a majority of viewers. The disadvantages are that slightly more image processing is required (you must rotate the left image), but this is easy to do in StereoPhotoMaker. The inverted mode accentuates slight lens elevation angle effects (at least in the V1, where the cameras do not point exactly parallel to the base, the pointing is raised slightly). This is well compensated by the tilt adjustment. | ||||||||||||||||||
