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.

  • Note that the astra camera uses semaphores for process synchronization. If the camera start fails, the semaphore file may be left in /dev/shm, causing the next start to become stuck. To avoid this, run the following command before launching:
ros2 run orbbec_camera ob_cleanup_shm_node

This will clean up /dev/shm/.

  • To launch the cameras, run the following command:
ros2 launch orbbec_camera multi_camera.launch.py

Use hardware decoder to decode JPEG

rockchip and Amlogic

Depends on rockchip-mpp-dev and rockchip-rga-dev, not all systems have these two packages, the names may be different, please search by yourself. Open CMakeLists.txt and set USE_RK_HW_DECODER to ON.

Nvidia Jetson

Depends on: jetson_multimedia_api,libyuv. Open CMakeLists.txt and set USE_NV_HW_DECODER to ON.

Launch parameters

The following are the launch parameters available:

  • connection_delay: The delay time in milliseconds for reopening the device. Some devices, such as Astra mini, require a longer time to initialize and reopening the device immediately can cause firmware crashes when hot plugging.
  • enable_point_cloud: Enables the point cloud.
  • enable_colored_point_cloud: Enables the RGB point cloud.
  • point_cloud_qos, [color|depth|ir]_qos,``[color|depth|ir]_camera_info_qos: ROS2 Message Quality of Service (QoS) settings. The possible values are SYSTEM_DEFAULT, DEFAULT,PARAMETER_EVENTS, SERVICES_DEFAULT, PARAMETERS, SENSOR_DATA and are case-insensitive. These correspond to rmw_qos_profile_system_default, rmw_qos_profile_default, rmw_qos_profile_parameter_events, rmw_qos_profile_services_default, rmw_qos_profile_parameters, and SENSOR_DATA, respectively.
  • enable_d2c_viewer: Publishes the D2C overlay image (for testing only).
  • device_num: The number of devices. This must be filled in if multiple cameras are required.
  • color_width, color_height, color_fps: The resolution and frame rate of the color stream.
  • ir_width, ir_height, ir_fps: The resolution and frame rate of the IR stream.
  • depth_width, depth_height, depth_fps: The resolution and frame rate of the depth stream.
  • enable_color: Enables the RGB camera.
  • enable_depth: Enables the depth camera.
  • enable_ir: Enables the IR camera.
  • depth_registration: Enables hardware alignment the depth frame to color frame. This field is required when the enable_colored_point_cloud is set to true.
  • usb_port: The USB port of the camera. This is required when multiple cameras are used.
  • enable_accel : Enables the accelerometer.
  • accel_rate: The frequency of the accelerometer, the optional values are 1.5625hz,3.125hz,6.25hz,12.5hz,25hz,50hz, 100hz,200hz,500hz,1khz,2khz,4khz,8khz,16khz,32khz. The specific value depends on the current camera.
  • accel_range : The range of the accelerometer, the optional values are 2g,4g,8g,16g. The specific value depends on the current camera.
  • enable_gyro: Whether to enable the gyroscope.
  • gyro_rate : The frequency of the gyroscope, the optional values are 1.5625hz,3.125hz,6.25hz,12.5hz,25hz,50hz, 100hz,200hz,500hz,1khz,2khz,4khz,8khz,16khz,32khz. The specific value depends on the current camera.
  • gyro_range : The range of the gyroscope, the optional values are 16dps,31dps,62dps,125dps,250dps,500dps,1000dps,2000dps. The specific value depends on the current camera.
  • enumerate_net_device : Whether to enable the function of enumerating network devices. True means enabled, false means disabled. This feature is only supported by Femto Mega and Gemini 2 XL devices. When accessing these devices through the network, the IP address of the device needs to be configured in advance. The enable switch needs to be set to true.
  • depth_filter_config : Configure the loading path for the depth filtering configuration file. By default, the depth filtering configuration file is located in the /config/depthfilter directory,Supported only on Gemini2.

Depth work mode switch

  • 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.

DDS Tuning

The default DDS settings (Galactic) may not be optimal for data transmission. Different DDS settings can have varying performance. In this example, we use CycloneDDS. For more detailed information, please refer to the ROS DDS Tuning。

Frequently Asked Questions

No Picture from Multiple Cameras

  • it's possible that the power supply is insufficient. To avoid this, do not connect all cameras to the same hub and use a powered hub instead.

  • It's also possible that the resolution is too high. To resolve this, try lowering the resolution.

Why are there so many launch files here

  • The reason for the presence of multiple launch files is due to the fact that the default resolutions and image formats of different cameras vary. To make it easier to use, the launch files have been separated for each camera.
