OrbbecSDK ROS2

stable version

OrbbecSDK_ROS2 is a wrapper for the Orbbec 3D camera that provides seamless integration with the ROS 2 environment. It supports ROS 2 Foxy, Humble, and Jazzy distributions.

With the major update of the new branch v2-main in October 2024, OrbbecSDK_ROS2 is connected to the open source version of OrbbecSDK v2, which will make OrbbecSDK_ROS2 more flexible and extensible. This update in v2-main ensures compatibility with all new Orbbec USB products that comply with the UVC standard. However, OrbbecSDK_ROS2 v2 no longer supports Orbbec's traditional OpenNI protocol devices. We encourage you to check whether your device is supported by OrbbecSDK_ROS2 v2 and use the new version if supported.

Efficient intra-process communication:

Our ROS2 Wrapper node supports zero-copy communications if loaded in the same process as a subscriber node. This can reduce copy times on image/pointcloud topics, especially with big frame resolutions and high FPS.

You will need to launch a component container and launch our node as a component together with other component nodes. Further details on "Composing multiple nodes in a single process" can be found here.

Further details on efficient intra-process communication can be found here.

Example

Manually loading multiple components into the same process

  • Start the component:

    ros2 run rclcpp_components component_container

  • Add the wrapper:

    ros2 component load /ComponentManager orbbec_camera orbbec_camera::OBCameraNodeDriver -e use_intra_process_comms:=true

    Load other component nodes (consumers of the wrapper topics) in the same way.

Using a launch file

ros2 launch orbbec_camera gemini_intra_process_demo_launch.py

Limitations

  • Node components are currently not supported on RCLPY
  • Compressed images using image_transport will be disabled as this isn't supported with intra-process communication

Use V4L2 backend

To enable the V4L2 backend for the Gemini2 series cameras, follow these steps:

  1. The Gemini2 series cameras support the V4L2 backend.
  2. Open the config/OrbbecSDKConfig_v1.0.xml file.
  3. Set the navigation option to LinuxUVCBackend.
  4. Change the backend setting to V4L2.

Note: The V4L2 backend is not enabled by default.

Launch parameters

The following are the launch parameters available:

  • enable_hole_filling_filter: This filter fills all holes in the depth map using the specified mode.
  • retry_on_usb3_detection_failure: If the camera is connected to a USB 2.0 port and is not detected, the system will attempt to reset the camera up to three times. This setting aims to prevent USB 3.0 devices from being incorrectly recognized as USB 2.0. It is recommended to set this parameter to false when using a USB 2.0 connection to avoid unnecessary resets.
  • enable_3d_reconstruction_mode: Enables 3D reconstruction mode. Default is false. When set to true, the camera laser operates in on-off mode, capturing IR images (laser off) for VSLAM localization and depth images (laser on) for point cloud computation.
  • tf_publish_rate: The rate at which the camera publishes dynamic transforms. The default value is 0.0, which means static transforms are published.
  • time_domain: The frame time domain, string type, can be device, global, or system. device means using the hardware timestamp from the camera, system means using the timestamp when the PC received the first packet of data or frame, and global is used for synchronized time across multiple devices, aligning data from different sources to a common time base.
  • enable_sync_host_time: Enables synchronization of the host time with the camera time. The default value is true, if use global time, set to false. Some old devices may not support this feature.
  • config_file_path: The path to the YAML configuration file. The default value is "". If the configuration file is not specified, the default parameters from the launch file will be used. If you want to use a custom configuration file, please refer to gemini_330_series.launch.py. enable_heartbeat enables the heartbeat function, which is set to false by default. If set to true, the camera node will send heartbeat signals to the firmware, and if hardware logging is desired, it should also be set to true.
  • log_level : SDK log level, the default value is info, the optional values are debug, info, warn, error, fatal.
  • enable_color_undistortion: Enables color undistortion, the default value is false. Note that our color cameras exhibit minimal distortion, and typically, undistortion is not necessary.
  • color_brightness: Color brightness.
  • ir_brightness: IR brightness.
  • color_ae_max_exposure: Color auto exposure maximum exposure.
  • ir_ae_max_exposure: IR auto exposure maximum exposure.
  • enable_hardware_reset: This option enables the hardware reset function. By default, it is set to false. If set to true, the camera will reboot upon its first connection.

Depth work mode switch

Orbbec SDK ROS 2 supports the depth work mode switch. The depth work mode switch is supported by Gemini 2, Gemini 2 L, and Femto and Femto Bolt cameras.

  • Before starting the camera, depth work mode (depth_work_mode) can be configured for the corresponding xxx.launch.py file's support.
  • The depth work mode switch is supported by Gemini 2, Gemini 2 L, and Gemini 2 XL cameras.
  • The default depth work mode configuration of xxx.launch.py is the camera's default configuration. If you need to modify it, you can switch to the corresponding mode as needed.
  • The specific camera depth work mode support types can be found in the comments of the depth mode.
# Depth work mode support is as follows:
# Unbinned Dense Default
# Unbinned Sparse Default
# Binned Sparse Default
# Obstacle Avoidance
DeclareLaunchArgument('depth_work_mode', default_value='')
  • View depth work modes:
ros2 run orbbec_camera list_depth_work_mode_node

Configuration of depth NFOV and WFOV modes

For the Femto Mega and Femto Bolt devices, the NFOV and WFOV modes are implemented by configuring the resolution of Depth and IR in the launch file. In launch file, depth_width、depth_height、ir_width、ir_height represents the resolution of the depth and the resolution of the IR. The frame fps and resolution of IR must be consistent with the depth. The correspondence between different modes and resolutions is as follows:

  • NFOV unbinned: 640 x 576.
  • NFOV binned: 320 x 288.
  • WFOV unbinned: 1024 x 1024.
  • WFOV binned: 512 x 512.

All available service for camera control

The name of the following service already expresses its function. However, it should be noted that the corresponding set_[ir|depth|color]* and get[ir|depth|color]* services are only available if you set enable[ir|depth|color] to true in the stream that corresponds to the argument of the launch file.

Network device enumeration

Currently, the network device enumeration function is supported only by the Femto Mega device. When accessing this device over the network, if enumerate_net_device is set to true, the device will be automatically enumerated, eliminating the need to configure the IP address in advance or set the enable switch to true. The specific configuration methods are as follows:

  • enumerate_net_device: enumeration network device automatically, only supported by Femto Mega. if enumerate_net_device set to true, the device will be enumerated automatically,No need to set the net_device_ip and net_device_port parameters.
  • net_device_ip: The IP address of the device.
  • net_device_port: The port number of the device.

Multi-Camera

  • To get the usb_port of the camera, plug in the camera and run the following command in the terminal:
ros2 run orbbec_camera list_devices_node
  • Set the device_num parameter to the number of cameras you have.
  • Go to the OrbbecSDK_ROS2/launch/multi_xxx.launch.py file and change the usb_port.
  • Don't forget to put the include tag inside the group tag. Otherwise, the parameter values of different cameras may become contaminated.
