Abstract
A real-time structured light depth extraction system includes a projector for projecting structured light patterns onto an object of interest. A camera positioned off-axis from the projector samples light reflected from the object synchronously with the projection of structured light patterns and outputs digital signals indicative of the reflected light. An image processor/controller receives the digital signals from the camera and processes the digital signals to extract depth information of the object in real time.
