ros2_object_analytics

Object Analytics (OA) is ROS2 module for real time object tracking and 3D localization. These packages aim to provide real-time object analyses over RGB-D camera inputs, enabling ROS developer to easily create amazing robotics advanced features, like intelligent collision avoidance, people follow and semantic SLAM. It consumes sensor_msgs::Image and sensor_msgs::PointClould2 data delivered by RGB-D camera, subscribes topic on object detection, publishes topics on object tracking in 2D RGB image and object localization in 3D camera coordination system.

OA keeps integrating with various "state-of-the-art" algorithms.

System Requirements

We support Ubuntu Linux Bionic Beaver 18.04 on 64-bit. We not support Mac OS X and Windows.

Hardware Requirements

Intel NUC (CPU: Intel i7-6700HQ @2.60GHz, Mem:16G)

Dependencies

Install ROS2 desktop packages ros-dashing-desktop

sudo apt-get install ros-dashing-desktop

The ros-dashing-desktop will include below packages.

ament_cmake
std_msgs
sensor_msgs
geometry_msgs
rclcpp
rosidl_default_generators
rosidl_interface_packages
launch
ros2run
class_loader
pcl_conversions

Install ROS2 dependencies

sudo apt-get install ros-dashing-cv-bridge ros-dashing-object-msgs ros-dashing-image-transport

Install OA debian packages

sudo apt-get install ros-dashing-object-analytics-msgs ros-dashing-object-analytics-node ros-dashing-object-analytics-rviz

Notes: debian installed package does not support 2d tracking feature since the dependent opencv3.3 debian package is not available. For full feature, please build opencv3.3 and install object analytics from source.

Install OA from source

Build OpenCV3

OpenCV3 & opencv-contrib 3.3 (OA depends on tracking feature from OpenCV Contrib 3.3. OpenCV 3.3 is not integrated in ROS2 dashing release, need to build and install Opencv3 with contrib from source to apply tracking feature)

# Build and Install OpenCV3 with opencv-contrib
mkdir ${HOME}/opencv
cd ${HOME}/opencv
git clone https://github.com/opencv/opencv.git -b 3.3.0
git clone https://github.com/opencv/opencv_contrib.git -b 3.3.0
mkdir opencv/build -p
cd opencv/build
cmake -DOPENCV_EXTRA_MODULES_PATH=${HOME}/opencv/opencv_contrib/modules \ 
      -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_opencv_cnn_3dobj=OFF ..
make -j8
sudo make install
sudo ldconfig

Install OpenCV3 dependencies

sudo apt-get install liblz4-dev

Build ros2_object_analytics

# get code
cd ~/ros2_ws/src
git clone https://github.com/intel/ros2_object_analytics.git -b devel (devel branch is the latest code with 2D tracking features, while master branch is stable for ros2 released distributions)

# build
cd ~/ros2_ws
source /opt/ros/dashing/setup.bash
colcon build --symlink-install

Run

Customize launcher

Object Analytics Module consumes 2D image/Point cloud/Detection bounding box from outside, so you need config the sources according to your specific condition. We provided a sample launch file "object_analytics_sample.launch.py", you can customize the remapping topics to have your own launcher.

By default, object analytics will launch both tracking and localization features, but either tracking or localization or both can be dropped. Detailed please refer arguments embedded in launch file "object_analytics_sample.launch.py".

Run sample launcher co-work with Realsense and OpenVINO

# Start OA demo to co-work with Realsense and OpenVINO
Step1: launch ROS2 Realsense and OpenVINO
  a) Please refer below links to enable ROS2 realsense and openvino.
     Realsense: https://github.com/intel/ros2_intel_realsense
     OpenVino:  https://github.com/intel/ros2_openvino_toolkit
  b) Make sure below topics works well, or please config the remapping topics in "object_analytics_sample.launch.py":
     1. /camera/color/image_raw
     2. /camera/aligned_depth_to_color/color/points
     3. /ros2_openvino_toolkit/detected_objects

Step2: if ros2_openvino_toolkit got from Robotics_SDK
     ros2 launch object_analytics_node object_analytics_sample.launch.py

Subscribed topics

/object_analytics/rgb (sensor_msgs::msg::Image)

/object_analytics/detected_objects (object_msgs::msg::ObjectsInBoxes)

/object_analytics/pointcloud (sensor_msgs::msg::PointCloud2)

Published topics

/object_analytics/localization (object_analytics_msgs::msg::ObjectsInBoxes3D)

/object_analytics/tracking (object_analytics_msgs::msg::TrackedObjects)

Tools

To ensure the algorithms in OA components to archive best performance in ROS2, we have below tools used to examine design/development performance/accuracy/precision..., more tools are in developing progress and will publish later.

1. tracker_regression

The tools is used to feed tracking node with raw images from datasets within fixed time interval(33ms), also simulate detector send ground truth as detections to tracking node for rectification, then receive tracking results for precision and recall statistics. It support multiple algorithms(dynamic configure to tracking node when start).

* Tools usages

# ros2 run object_analytics_node tracker_regression --options
       options: [-a algorithm] [-p dataset_path] [-t dataset_type] [-n dataset_name] [-h];
       -h : Print this help function.
       -a algorithm_name : Specify the tracking algorithm in the tracker.
          supported algorithms: KCF,TLD,BOOSTING,MEDIAN_FLOW,MIL,GOTURN.
       -p dataset_path : Specify the tracking datasets location.
       -t dataset_type : Specify the dataset type: video,image.
       -n dataset_name : Specify the dataset name

* Example:

Video dataset with tracking algorithm("MEDIAN_FLOW"):
# ros2 run object_analytics_node tracker_regression -p /your/video/datasets/root/path -t video -n dudek -a MEDIAN_FLOW

Image dataset with default algorithm("MEDIAN_FLOW"):
# ros2 run object_analytics_node tracker_regression -p /your/image/datasets/root/path -t image -n Biker -a MEDIAN_FLOW

* Dataset:

Support both video and image dataset, but you may need to translate into below formats.

Video dataset: (Refer to opencv_extra tracking dataset)
