Object Following Robot Using Raspberry Pi and Open CV – Python

Abstract

Object detection and tracking are important and challenging tasks in computer vision applications such as surveillance, vehicle navigation and autonomous robot navigation. Object detection involves locating objects in the frame of a video sequence. There are three key steps in video analysis, detection interesting moving objects, tracking of such objects from each and every frame, and analysis of object tracks to recognize their behavior. This project mainly focuses on Raspberry Pi ARM-11 based processor utilization, image processing. Here the webcam is interfaced to it using the USB ports available on board. Images captured by the webcam are sent to the Raspberry pi board where the processing of the image will be done. After this, the code gets executed and the dc motors are rotated in accordance to the written code and rotate as left, right, forward and backwards depends upon the object movement. It maintains the constant distance between the object and the robot. This robot can be used in both military and commercial applications like in hostage situations which can reduce risk of damage to human life.
