SPATIAL 3D STERIOSCOPIC INTRAORAL CAMERA SYSTEM BACKGROUND

摘要

Spatial 3D stereoscopic video is generated with a dual camera subassembly in a hand held device. The 3D Left-Right Multiplexed Spatial Stereoscopic video stream is wirelessly coupled to a processing system for simultaneous visualization comparison with intraoral cavity digital dental impression 3D CAD formatted files, Cone Beam Panoramic Computed Tomography images, Optical Coherence Tomography planar images and Panoramic X-ray image digital files for Stereoscopic visualization on stereoscopic displays and occluding viewing glasses.

1. A spatial 3D stereoscopic intraoral camera system comprising:
processor; memory; wireless component; dual side-by-side camera CCD subassemblies; the sensor subassemblies each having an optical path through a lens disposed to direct light to a CCD; each lens comprising an optical path through an optical lens or pin hole disposed to direct light on CCD; the duel side-by-side subassemblies each having a CCD imaging chip converging optical paths of subassemblies by tilt, tilt range of between 1° to 5° off the surface mount plane, or shift, shift gap symmetrical with the duel assembly centerline of between 0.5 mm and 5.0 mm, for focus control to achieve the stereoscopic convergence; the CCDs operatively connected and mounted on daughterboard's with a lens focal gap of between 0.01 and 3.0 mm each; each subassembly surrounded by an array of LEDs; each subassembly surface mounted on a motherboard supporting electronic components for processing the CCD image signals and LEDs power and control, and software instructions in the form of device logic stored in memory for enabling the device, under control of the processors to format the signal images for wireless transport to remote processing system for storage and display in 3D Line Sequential Left-Right Multiplexed Spatial Stereoscopic format,whereby spatial 3D intraoral images are converged and captured by the duel subassemblies for processing and display in stereoscopic rendering and viewing.
