Hardware Overview​

Gemini Series Quickstart Guide​

  • Connect the Orbbec Camera ① Assemble the tripod head with the tripod, and then secure the camera onto the assembled tripod, as illustrated in Step 1 below.

    ② Use the USB-C to USB-A cable to connect the camera’s Type-C port, as shown in Step 2 below.

    ③ Connect the USB-A connector to the host using the same USB-C to USB-A cable, as shown in Step 3 below.

  • Get Orbbec Viewer

Select and download the corresponding Orbbec Viewer based on your system and version.

  • Launch Orbbec Viewer
  1. After starting the Orbbec Viewer, please make sure that the tool recognizes the 3D camera, as indicated by the following image. 【Remark】If the camera is not recognized, please check to ensure that the camera and the host are properly connected. You can try disconnecting and then reconnecting the USB cable. If it still isn’t recognized, consider replacing the USB cable or verifying whether the host computer’s power supply meets the required specifications.
  1. Toggle the ‘Depth’ button at the top of the tool to start and preview the depth stream.
  1. Toggle the ‘Color‘ button at the top of the tool to start and preview the color stream. The color stream and depth stream will be displayed side by side.
  1. Toggle the ‘IR Left’ and ‘IR Right’ buttons at the top of the tool to strat and preview the IR stream.
  1. Toggle the ‘IMU’ button at the top of the tool to start and preview the IMU stream.
  1. Toggle the button on the top of each window to show the metadata information.
  1. Toggle the ‘PointCloud‘ button at the top of the tool to start and preview the 3D point cloud
  1. Toggle the ‘Display’ button under the ‘Image View’ menu on the left to start and preview the D2C (depth to color registration) stream. The 3D point cloud and the D2C stream will be displayed side by side.

Getting Start on reComputer​

Step 1. Download and install the Orbbec SDK for ARM64 architecture:

# Download Orbbec SDK
wget https://github.com/orbbec/OrbbecSDK_v2/releases/download/v2.4.11/OrbbecSDK_v2.4.11_202508040936_058db73_linux_aarch64.zip

# Unzip the SDK
unzip OrbbecSDK_v2.4.11_202508040936_058db73_linux_aarch64.zip

Step 2. Build examples and test:

# Install udev rules
cd OrbbecSDK_v2.4.11_202508040936_058db73_linux_aarch64/shared/
sudo chmod +x ./install_udev_rules.sh
sudo ./install_udev_rules.sh
sudo udevadm control --reload-rules && sudo udevadm trigger
# Build examples and setup
cd ..
./build_examples.sh
./setup.sh
