A Time of Flight camera module featuring a MIPI-CSI 2 connection and offering up to 4-meter measuring range with sub-2cm precision, designed and optimized exclusively for Raspberry Pi & Nvidia Jetson boards.

Quick sum-up about the camera:

  • Real-time point cloud and depth map.
  • Resolution: 240×180@30fps on RPI4/CM4
  • Up to 4M measuring distance
  • Onboard 940nm laser for both indoor & outdoor uses, no external light source needed.
  • V4L2-based video kernel device
  • C/C++/Python SDK for userland depth map output and example source code
  • ROS ready.
  • 38 x 38mm board size

How ToF Works

ToF stands for “Time of Flight”. A ToF Camera emits modulated lights (CW method) and uses the time it takes for the said lights to be reflected back to measure the distance/depth info of any given object/scene, and you can obtain depth data (X,Y & Z coordinate position) in every pixel. Light travel is calculated with d=C/2f, where C is the speed of light and f is the modulation frequency.
