Description
The Intel RealSense Depth Module D420 a high quality imaging sub-system that features wide field of view stereo image sensors. When integrated with a RealSense Vision Processor, the D420 module is able to output depth data over USB.
Stereo Vision Depth Technology
The Intel RealSense D400 series depth camera uses stereo vision to calculate depth. The stereo vision implementation consists of a left imager, right imager, and an optional infrared projector. The infrared projector projects non-visible static IR pattern to improve depth accuracy in scenes with low texture. The left and right imagers capture the scene and sends imager data to the depth imaging (vision) processor, which calculates depth values for each pixel in the image by correlating points on the left image to the right image and via shift between a point on the Left image and the Right image. The depth pixel values are processed to generate a depth frame. Subsequent depth frames create a depth video stream.
