ABSTRACT:
An optical scanner for three-dimensional scanning comprises: a support bed; a flat, transparent plate; guide rails under the transparent plate; a carriage slidably attached to the guide rails; and one or more sensors attached to the bed/case or carriage. For three-dimensional imaging, multiple scanned images of the object are obtained, each of which is from light reflecting off the object at a different angle with respect to the path of the carriage. This is done by shining light on the object and appropriately channeling reflected light, from at least two different directions, into the sensor(s). In one embodiment, the carriage has three CCD sensors, one oriented rearwards (with respect to the path of travel of the carriage), one oriented vertically, and one oriented forwards—each effectively “sees” the object from a different orientation. The multiple scanned images can be used for stereoscopic viewing and/or three-dimensional rendering using a computer.
