USB2 Support for Intel® RealSense™ Technology

USB 2.0 support for Intel RealSense Depth Cameras

InteL® RealSense™ is pleased to announce USB2 support on Intel® RealSense™ D400 Series cameras. Intel RealSense cameras will now be able to integrate into low power embedded designs like Raspberry Pi*.

This is great news for anyone working with a small budget on lower frame rate and depth sensing projects. This integration allows independent developers, hobbyists, and OEMs to connect Intel RealSense cameras to a USB2 port with reduced bandwidth and camera capabilities, great for developing prototypes with a budget restriction.

Intel RealSense D400 Series depth cameras include:

    • A powerful vision processor, which uses 28 nanometer (nm) process technology and supports up to 5 MIPI Camera Serial Interface 2 lanes to compute real-time depth images and accelerate output
    • A new and advanced stereo depth algorithm for accurate depth perception and long range
    • A set of image sensors that allow devices to capture the disparity between images up to 1280×720 resolution
    • Support for the new cross-platform and open-source Intel RealSense SDK 2.0
    • A dedicated color image signal processor for image adjustments and scaling data
    • An active infrared projector to illuminate objects to enhance the depth data

Developers won’t need a big budget to use the depth sensing cameras but once connected with USB2, camera capabilities are reduced due to lack of bandwidth. When connected via USB2, Intel RealSense cameras can be used at these resolution/frame-rate combinations:

    • Resolution: 1280×720; FPS: 6
    • Resolution: 640×480; FPS: 6, 15, 30
    • Resolution: 480×270; FPS: 6, 15, 30, 60

This integration is great for low-cost prototypes; however, firmware update capabilities are not available over USB2. If a firmware upgrade is required, users will need to use a system that supports USB3.
