"Bellus3D worked closely with Spreadtrum to define and implement a dual-sensor structured light depth camera module that captures up to 200k 3D points with sub-millimeter depth accuracy. The new reference design contains two NIR sensors and a structured light projector, and offers greater depth resolution than the single-sensor structured light camera design deployed by iPhone X. It enables smartphone manufacturers to use off-the-shelf components to reduce costs and streamlines smartphone manufacturing by relaxing the tight calibration tolerances associated with single-sensor structured light depth camera module designs. In addition, Bellus3D software can automatically recalibrate the depth camera module after a smartphone is accidently dropped, which otherwise may require the product to be returned to the manufacturer for repair."
