## Introduction
The **OrbbecSDK ROS2 Wrapper** provides seamless integration of Orbbec cameras with the ROS 2 ecosystem.
It supports ROS2 **Foxy**, **Humble**, and **Jazzy** distributions.
- Default branch: **v2-main**
- For legacy **OpenNI** devices: use the **main** branch
- For users in China: use the [Gitee repository](https://gitee.com/orbbecdeveloper/OrbbecSDK_ROS2)
## branch selection
Here is the device support list of main branch (v1.x) and v2-main branch (v2.x):

**Note**: If you do not find your device, please contact our FAE or sales representative for help.
**Definition**:
1. Recommended for new designs: we will provide full supports with new features, bug fix and performance optimization;
2. Full maintenance: we will provide bug fix support;
3. Limited maintenance: we will provide critical bug fix support;
4. Not supported: we will not support specific device in this version;
5. To be supported: we will add support in the near future.
**Migration Guide**
If you need to migrate existing projects from the main (v1.x) branch to the v2-main (v2.x) branch, please refer to the official [migration guide](https://orbbec.github.io/OrbbecSDK_ROS2/en/source/7_developer_guide/migration_guide.html)
## Installation Instructions
**Environment configuration**
Install ROS 2 according to the official guide:
* [ROS 2 installation (Ubuntu)](https://docs.ros.org/en/humble/Installation/Ubuntu-Install-Debians.html)
Install dependencies:
```bash
sudo apt install libgflags-dev nlohmann-json3-dev \
ros-$ROS_DISTRO-image-transport ros-${ROS_DISTRO}-image-transport-plugins ros-${ROS_DISTRO}-compressed-image-transport \
ros-$ROS_DISTRO-image-publisher ros-$ROS_DISTRO-camera-info-manager \
ros-$ROS_DISTRO-diagnostic-updater ros-$ROS_DISTRO-diagnostic-msgs ros-$ROS_DISTRO-statistics-msgs ros-$ROS_DISTRO-xacro \
ros-$ROS_DISTRO-backward-ros libdw-dev libssl-dev
```
Enable ROS 2 auto-completion:
```bash
eval "$(register-python-argcomplete3 ros2)"
eval "$(register-python-argcomplete3 colcon)"
```
**Linux Binary Package Installation**
Check available packages:
```bash
sudo apt update
apt list | grep orbbec
```
Install OrbbecSDK ROS2 package:
```bash
sudo apt install ros-humble-orbbec-camera ros-humble-orbbec-description
```
After installation, you can use it directly without compilation.
**Build from Source**
Create a `colcon` workspace:
```bash
mkdir -p ~/ros2_ws/src
```
Clone source and checkout `v2-main` branch:
```bash
cd ~/ros2_ws/src
git clone https://github.com/orbbec/OrbbecSDK_ROS2.git
cd OrbbecSDK_ROS2
git checkout v2-main
```
Build:
```bash
cd ~/ros2_ws
colcon build --event-handlers console_direct+ --cmake-args -DCMAKE_BUILD_TYPE=Release
```
## Registration Script (Required)
To allow the Orbbec cameras to be recognized correctly on Linux, install the udev rules.
**Binary Installation**
```bash
sudo cp /opt/ros/$ROS_DISTRO/share/orbbec_camera/udev/99-obsensor-libusb.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && sudo udevadm trigger
```
**Build from Source**
```bash
cd ~/ros2_ws/src/OrbbecSDK_ROS2/orbbec_camera/scripts
sudo bash install_udev_rules.sh
sudo udevadm control --reload-rules && sudo udevadm trigger
```
This step is **mandatory** for Linux users.
`Notes:` If this script is not executed, open the device will fail due to permission issues. You need to run the sample with sudo (administrator privileges).
## Getting start
Launch camera node
- On terminal 1
```bash
source ~/ros2_ws/install/setup.bash
ros2 run orbbec_camera list_devices_node # Check if the camera is connected
ros2 launch orbbec_camera gemini_330_series.launch.py # Or other launch file, see below table
```
- On terminal 2
```bash
source ~/ros2_ws/install/setup.bash
rviz2
```
Select the topic you want to display
- List topics / services/ parameters ( On terminal 3)
```bash
ros2 topic list
ros2 service list
ros2 param list
```
- Echo a topic
```bash
ros2 topic echo /camera/depth/camera_info
```
- Call a service
```bash
ros2 service call /camera/get_sdk_version orbbec_camera_msgs/srv/GetString '{}'
```
For more usage details, please refer to the official [OrbbecSDK ROS2 documentation](https://orbbec.github.io/OrbbecSDK_ROS2/en/source/4_application_guide/application_guide.html)
## Supported Devices

All launch files are essentially similar, with the primary difference being the default values of the parameters set
for different models within the same series. Differences in USB standards, such as USB 2.0 versus USB 3.0, may require adjustments to these parameters. If you encounter a startup failure, please carefully review the specification manual. Pay special attention to the resolution settings in the launch file, as well as other parameters, to ensure compatibility and optimal performance.
