ros_object_analytics

Object Analytics (OA) is ROS wrapper for realtime object detection, localization and tracking. 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 and semantic SLAM. It consumes sensor_msgs::PointClould2 data delivered by RGB-D camera, publishing topics on object detection, object tracking, and object localization in 3D camera coordination system.

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

Object detection offload to GPU, ros_opencl_caffe, with Yolo v2 model and OpenCL Caffe framework
Object detection offload to VPU, ros_intel_movidius_ncs (devel branch), with MobileNet SSD model and Caffe framework

compiling dependencies

ROS packages from ros-kinetic-desktop-full

Other ROS packages

NOTE: OA depends on tracking feature from OpenCV (3.3 preferred, 3.2 minimum). The tracking feature is recently provided by ROS Kinetic package "ros-kinetic-opencv3" (where OpenCV 3.3.1 is integrated). However, if you're using an old version of ROS Kinetic (where OpenCV 3.2 is integrated), tracking feature is not provided. In such case you need self-build tracking from opencv_contrib. It is important to keep opencv_contrib (self-built) and opencv (ROS Kinetic provided) in the same OpenCV version that can be checked from "/opt/ros/kinetic/share/opencv3/package.xml"

Frequently used options
- input_points Specify arg "input_points" for the name of the topic publishing the sensor_msgs::PointCloud2 messages by RGB-D camera. Default is "/camera/depth_registered/points" (topic compliant with ROS OpenNI launch)
- aging_th Specifiy tracking aging threshold, number of frames since last detection to deactivate the tracking. Default is 16.
- probability_th Specify the probability threshold for tracking object. Default is "0.5".
```
roslaunch object_analytics_launch analytics_movidius_ncs.launch aging_th:=30 probability_th:="0.3"
```
