Acquiring and using three-dimensional information in a document scanning system

摘要: Systems and methods for acquiring using three-dimensional imaging data to improve the process of scanning bound documents are disclosed. The system includes a camera capturing an image such as books, second gathering regarding first camera's field view. Signal processing logic analyzes gathered by uses it determine whether view was obstructed. If is determined that obstructed, then remedial action can be taken, removing obstruction, recapturing image, and/or flagging further processing. may include laser range finder, ultrasonic device utilizes auto-focus finding technology, binocular array, trinocular array.
