Orbbec ROS SDK

Orbbec ROS SDK is a wrapper for Orbbec SDK that supports ROS Kinetic, Melodic, and Noetic distributions. It enables smooth integration of Orbbec 3D cameras into ROS projects.

Launch Parameters

The following launch parameters are available:

connection_delay: The delay time in milliseconds for reopening the device. Some devices 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.
color_width, color_height, color_fps: The resolution and frame rate of the color stream.
left_ir_width, left_ir_height, left_ir_fps: The resolution and frame rate of the left IR stream.
right_ir_width, right_ir_height, right_ir_fps: The resolution and frame rate of the right 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_left_ir: Enables the left IR camera.
enable_right_ir: Enables the right IR camera.
depth_registration: Enables hardware alignment of the depth frame to the color frame. This field is required when enable_colored_point_cloud is set to true.
log_level for OrbbecSDK controls console log verbosity, with levels none, info, debug, warn, fatal. Logs save in ~/.ros/Log. For file logging, adjust <FileLogLevel> in config/OrbbecSDKConfig_v1.0.xml.
ordered_pc: Whether the point cloud should be organized in an ordered grid (true) or as an unordered set of points (false).
device_preset: The default value is Default. Only the G330 series is supported. For more information, refer to the G330 documentation. Please refer to the table below to set the device_preset value based on your use case. The value should be one of the preset names listed in the table.
enable_decimation_filter: Only the G330 series is supported. This filter effectively reduces the depth scene complexity. The filter runs on kernel sizes [2x2] to [8x8] pixels. The image size is scaled down proportionally in both dimensions to preserve the aspect ratio.
enable_hdr_merge: This filter is used jointly with depth HDR function. By merging consecutive depth images of alternating exposure values, we can over come challenges in acquiring depth values for under-illuminated and over-illuminated objects simultaneously.
sequence_id_filter_id: This filter is used jointly with depth HDR function and outputs only the sequence with specified sequence ID.
enable_threshold_filter: This filter preserves depth values of interest and omits depth values out of scope.
enable_noise_removal_filter: This filter removes speckle noise in clusters and gives rise to a less-filled depth map.
enable_spatial_filter: This filter performs multiple iterations of processing as specified by the magnitude parameter, to enhance the smoothness of depth data. It is also capable of filling small holes in depth maps.
enable_temporal_filter:This filter is intended to improve the depth data persistency by manipulating per-pixel values based on previous frames. The filter performs a single pass on the data, adjusting the depth values while also updating the tracking history.
enable_hole_filling_filter: This filter fills all holes in the depth map using the specified mode.
depth_precision : The depth precision, should be like 1mm format. The default value is 1mm.
enable_laser : Whether to enable the laser. The default value is true.
laser_on_off_mode: Laser on/off alternate mode, 0: off, 1: on-off alternate, 2: off-on alternate. The default value is 0.
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.

IMPORTANT: Please carefully read the instructions regarding software filtering settings at this link. If you are uncertain, do not modify these settings.

Depth work mode switch:

Before starting the camera, depth work mode (depth_work_mode) can be configured for the corresponding xxx.launch 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 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 -->
<arg name="depth_work_mode" default=""/>

rosrun 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.

Available Services for Camera Control

The service names intuitively reflect their purposes. It's crucial to understand that services related to setting or getting parameters—denoted as set_* and get_*—become available only when the respective enable_* parameters are activated. For instance, enabling features such as left infrared (IR) with enable_left_ir, right IR with enable_right_ir, depth sensing with enable_depth, or color processing with enable_color (refer to Launch Parameters) is a prerequisite for their corresponding services to be operational. This configuration ensures that services are accessible only when their specific stream is enabled in the launch file's stream argument.

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.

Use Nodelet

For users who need to use nodelet, please refer to gemini2_nodelet.launch

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.

Error: "Failed to start device: usbEnumerator createUsbDevice failed!"

The current device does not have permission to access the device. Check the PID of the current device:
```
lsusb | grep 2bc5
```
Your output should look like this:
```
Bus 002 Device 007: ID 2bc5:your_pid_here
```
Edit /etc/udev/rules.d/99-obsensor-libusb.rules and add the following line:
```
SUBSYSTEM=="usb", ATTR{idProduct}=="your_pid_here", ATTR{idVendor}=="2bc5", MODE:="0666", OWNER:="root", GROUP:="video", SYMLINK+="your_device_name_here"
```
Replace your_pid_here with the PID of your device and your_device_name_here with the name you want to create for the device (e.g., gemini_camera).

Then restart the udev service:
```
sudo udevadm control --reload-rules && sudo service udev restart && sudo udevadm trigger
```
