An electronic still camera comprising a lens, shutter, and exposure control system, a focus and range control circuit, a solid state imaging device incorporating a Charge Couple Device (CCD) through which an image is focused, a digital control unit through which timing and control of an image for el ...
An imaging method and system for 3D modeling of a 3D surface forms a mosaic from multiple uncalibrated 3D images, without relying on camera position data to merge the 3D images. The system forms the 3D model by merging two 3D images to form a mosaiced image, merging the mosaiced image with another 3 ...
An intra-oral imaging system that produces images of a dental surface includes a probe that contains an optical conduit for transmitting light with spatially varying wavelengths for illuminating a dental surface and a camera for receiving light rays reflected from the dental surface. The invention a ...
A three-dimensional imaging method and system illuminates an object to be imaged with a light pattern that is formed from two or more light sub-patterns. The sub-patterns can each encompass the visible light spectrum or can be spatially varying intensity sub-patterns that each correspond to a red, g ...

Positions can be precisely and accurately fixed instantaneously within a three-dimensional workspace. A system of two or more transmitters each continuously sweep the workspace with two fanned laser beams which are preferably about 90 degrees apart on the rotational axis of the transmitter. A receiv ...
A method and system allows conversion of three-dimensional data from a default coordinate frame to an arbitrary user-selected coordinate frame. The method includes obtaining position data in a default coordinate frame and transforming the data into an alternate coordinate frame defined by the user. ...
An improved three-dimensional position detector and measurement system includes one or more transmitters that each transmit planar light beams and a strobe pulse and a receiver that responds to illumination from the beams and the strobe. The receiver in the system includes calibration logic for exec ...
An improved low cost theodolite position measurement system and process which is particularly useful in enabling a single operator to conveniently set up the system and calculate elevation (el) and azimuth (az) angle data. Only a single optical transmitter is positioned within a predetermined worksp ...
A high-speed three-dimensional imaging system and method projects a spatially varying intensity pattern onto an object or scene to be imaged using a laser light source in conjunction with a scanner. The pattern varies in intensity with respect to the projection angle. A pixel intensity ratio is calc ...
