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.

Note

Make sure you are running a newer version of Jetpack (4.6.1 or later). A fresh install is highly recommended.

Using the camera on Jetson Nano/Xavier NX

Follow each of the steps by running their respective command shown below.

Step 1. Pull the repository.

git clone https://github.com/ArduCAM/Arducam_tof_camera.git

Step 2. Change the directory to Arducam_tof_camera/jetson

cd Arducam_tof_camera/jetson

Step 3. *Installation (Driver, Dependencies, SDK, OpenCV)*

./Install_dependecies_jetson.sh

When you see the reboot prompt, enter y.

Step 4. compile & run

./compile.sh

Once it’s successfully compiled, live previews of the camera will automatically pop up.

Instructions for Safe Use

To properly use the Arudcam ToF Camera, kindly note:

  • Before connecting, you should always power the Jetson Nano/Xavier NX off and remove the power supply first.
  • Make sure the cable on the camera board is locked in place.
  • Make sure the cable is correctly inserted in the Jetson Nano/Xavier NX board’s MIPI CSI-2 connector.
  • Avoid high temperatures.
  • Avoid water, moisture, or conductive surfaces while in operation.
  • Avoid folding, or straining the flex cable.
  • Avoid cross-threading with tripods.
  • Gently push/pull the connector to avoid damaging the printed circuit board.
  • Avoid moving or handling the printed circuit board excessively while it’s in operation.
  • Handle by the edges to avoid damage from electrostatic discharge.
  • Where the camera board is stored should be cool and as dry as possible.
  • Sudden temperature/humidity changes can cause dampness in the lens and affect the image/video quality.
