Abstract
Described is a method and system for fast three-dimensional imaging using defocusing and feature recognition is disclosed. The method comprises acts of capturing a plurality of defocused images of an object on a sensor, identifying segments of interest in each of the plurality of images using a feature recognition algorithm, and matching the segments with three-dimensional coordinates according to the positions of the images of the segments on the sensor to produce a three-dimensional position of each segment of interest. The disclosed imaging method is 'aware' in that it uses a priori knowledge of a small number of object features to reduce computation time as compared with 'dumb' methods known in the art which exhaustively calculate positions of a large number of marker points.
