A Calibrating Method for Projected-Type Auto-Stereoscopic 3 D Display System with DDHOE

A new calibrating method for binocular autostereoscopic display system, which using digitally designed holographic optical element (DDHOE) to diffract projected light to observer, was proposed. In this method, the auto-scanning, auto-capturing, and image process were used to calibrate the DDHOE position to figure out the left eye, right eye, and nonworkable lines in projection image.
