Ball Tracking Using OpenCV And ROS

Demo

Steps to Replicate

git clone https://github.com/trunc8/Ball_Tracking_Using_OpenCV_And_ROS.git ball_tracking in the src folder of your catkin_ws (or equivalent ROS workspace).
roscore in Tab 1
rosrun ball_tracking video_publisher.py in Tab 2
rosrun ball_tracking ball_tracker.py in Tab 3

What This Does

video_publisher.py reads video file using OpenCV, converts the frames to ROS Image Message using CvBridge and publishes to topic '/ball_video'
ball_tracker.py subscribes to the ROS Image topic, suitably converts to OpenCV image and performs contour tracking on the ball
