ROS and OpenCv for beginners | Blob Tracking and Ball Chasing with Raspberry Pi

** Visit my brand new portal at https://tiziano-school.thinkific.com/ where you can find this ROS series as a FREE course ** ROS and OpenCV can work together for accomplishing incredible tasks. In this tutorial for beginners we are going to use the Rover's camera for detecting and tracking a blue golf ball. We will develop multiple nodes, each responsible of one particular task: - capturing and streaming the camera - detecting the ball - calculating control actions to track the ball - controlling the rover to follow the ball We will be building up on everything we have learned in the previous tutorials: you can find the complete playlist right here: /watch/vNYCBSp-p42aQRqVIQs0UB9UtGUQWetuLP=tsil&IRk2GWL2K6N2C *** Find the code: https://github.com/tizianofiorenzani/ros_tutorials *** Build and setup the robot: /watch/IhdeRI_IiLiIe *** Simple Ball Tracking example from Pyimagesearch: https://www.pyimagesearch.com/2015/09/14/ball-tracking-with-opencv/ *** imutils library for image processing: https://github.com/jrosebr1/imutils *** Simple blob detect ** Example from Satya Mallick: https://www.learnopencv.com/blob-detection-using-opencv-python-c/ ** Docs on opencv.org: https://docs.opencv.org/3.4/d0/d7a/classcv_1_1SimpleBlobDetector.html ******** STORE https://teespring.com/stores/geekmeup - Raspberry Pi 4 (4 GB RAM): https://amzn.to/36GqwXf - Raspberry Pi 4 (2 GB RAM): https://amzn.to/2Aj7Pg3 - Wide angle camera: https://amzn.to/2Pwc6P7 ******** Find me on Facebook https://www.facebook.com/tizianotutorials ******** Find me on Linkedin https://www.linkedin.com/in/tiziano-fiorenzani/ ******** Find me on Twitter https://twitter.com/TFiorenzani ** Go to my channel: https://goo.gl/BjLGnS ** Check out my latest video: https://goo.gl/ZhcNi4 ** Check out my most popular video: https://goo.gl/5KMJnU #ros #opencv #blobtracking
