Image Processing Based Human Pursuing Robot

Abstract

This paper is about a robot which is made to follow a human being through computer vision. The system looks for a barcode in the video frame and when found, it is bounded into a rectangle and the center coordinates of the rectangle are found out. These coordinates are compared with the center of the image and on the basis of the horizontal position of barcode the commands are given to the robot, to move left, right or forward. This Robot for image processing uses OpenCV library and programming with python. The processor board used for the robot is Raspberry pi for image processing and Arduino is used to driving motors. An ultrasonic sensor is used to calculate the distance between the robot and the human being.
