Humble-v4.0.8

v4.0.8 for ZED SDK v4.0.8

• The parameter general.sdk_verbose has been moved to debug.sdk_verbose and set to 0 as default.
• Add new parameter general.optional_opencv_calibration_file to use custom OpenCV camera calibrations.
• Add new tutorial to illustrate how to integrate one or more ZED cameras on a robot
• Add 'simulation.sim_enabled' parameter to enable the simulation mode
• Add 'simulation.sim_address' parameter to set the simulation server address
• Add 'simulation.sim_port' parameter to set the simulation server port
• Add /clock subscriber to check the presence of the required message when use_sim_time is true
• Force grab_frame_rate and pub_frame_rate to 60 Hz in simulation
• Force grab_resolution to HD1080 in simulation
• Remove the general.zed_id parameter. Always use general.serial_number to distinguish between different cameras in a multi-camera configuration.
• The multi-camera example has been updated to match the new TF configuration
• The old launch files are now obsolete: 'ros2 launch zed_wrapper <camera_model>.launch.py' is replaced by 'ros2
  launch zed_wrapper zed_camera.launch.py camera_model:=<camera_model>'
• The reference link for positional tracking is no longer 'base_link' but <camera_name>_camera_link.
  This will allow an easier ZED integration in existing robot configuration because the transform base_link -> camera_link
  is no longer published by the ZED ROS2 Wrapper. Thanks to @SteveMacenski for the advice
  • Remove parent and origin parameters from zed_macro.urdf.xacro
  • Remove launch argument cam_pose from zed_camera.launch.py
• Move parameter publish_imu_tf from pos_tracking to sensors to make it available also in "no depth" configurations of the node
• Add new parameter pos_tracking.pos_tracking_mode to exploit the new ZED SDK QUALITY mode for improved odometry and localization
• New Video/Depth processing throttling method by using the grab_compute_capping_fps ZED SDK parameter instead of a dedicated thread
• Advanced parameters to handle Thread scheduling policy and priorities (sudo required):thread_sched_policy,thread_grab_priority,
  thread_sensor_priority,thread_pointcloud_priority
• Add new GNSS calibration parameters: enable_reinitialization, enable_rolling_calibration, enable_translation_uncertainty_target, gnss_vio_reinit_threshold, target_translation_uncertainty, target_yaw_uncertainty
• Add new Plane Detection parameters: pd_max_distance_threshold, pd_normal_similarity_threshold

Note: ROS 2 Foxy support is deprecated although this version still works with Foxy

Foxy-Humble-v4.0.5

v4.0.5 - ZED SDK from v4.0.0 to v4.0.5

• The parameter general.pub_resolution can now take only NATIVE and CUSTOM values. 'NATIVE' to use the same general.grab_resolution - CUSTOM to apply the general.pub_downscale_factor downscale factory to reduce bandwidth in transmission
• Add new parameter general.pub_downscale_factor to be used with the new option CUSTOM for the parameter general.pub_resolution
• ULTRA is the new default value for depth.depth_mode (better performance for odometry and positional tracking)
• Add resolution HD1080 for ZED X
• Fix issue with Body Tracking start/stop by service call. Now Body Tracking can be restarted multiple times
• Fix depth grab performance by removing a not required PNG Write call. Thank you Esteban Zamora @ezamoraa
• Fix bug with general.pub_resolution value, not allowing to select the correct data publish resolution
• Add new launch parameter ros_params_override_path to provide the path to a custom YAML file to override the parameters of the ZED Node without modifying the original files in the zed_wrapper/config folder. Thank you David Lu @MetroRobots

Foxy-Humble-v3.8.2

This is the latest release working with the ZED SDK v3.8.2

Changelog

• Removed annoying build log messages. Only warning regarding unsupported ROS2 distributions will be displayed when required.

• Added a check on timestamp to not publish already published point cloud messages in the point cloud thread

• Added Docker files (docker folder) ready to create Docker images for desktop host devices: Ubuntu 22.04, ROS2 Foxy, ZED SDK v3.8.2.

• Add new LOW value for general.pub_resolution (half the MEDIUM output resolution).

• Fix distortion model (see Issue #128)

• Added diagnostic warning if the frequency of the camera grabbing thread is minor than the selected general.grab_frame_rate value.

• Improved the code for Moving Average calculation for better node diagnostics.

• Temperature diagnostic is now always updated even if sensors.sensors_image_sync is true and no image topics are subscribed.

• Improve Grab thread and Video/Depth publishing thread elaboration time diagnostic.

• Improve thread synchronization when the frequency of the grab SDK function is minor of the expected camera frame rate setting because of a leaking of elaboration power.

• Removed node parameter general.resolution, replaced by general.grab_resolution.

• Added node parameter general.pub_resolution used to reduce node computation and message bandwidth.

  • Available output resolutions: HD2K, HD1080, HD720, MEDIUM, VGA. MEDIUM is an optimized output resolution to maximize throughput and minimize processing costs.

  • Removed the workaround for empty svo_path launch parameter values thanks to TextSubstitution.
  • Modified the "display" launch files in zed-ros2-examples to match the new configuration.
  • Added publish_tf and publish_map_tf launch parameters useful for multi-camera configuretion or external odometry fusion.

• Change LICENSE to Apache 2.0 to match ROS2 license.

• Added zed_id and serial_number launch parameters to open the correct camera in multi-camera configurations.
