DESIGN AND IMPLEMENT THE OBJECT-TRACKING VEHICLE

Abstract

This article researches the application of image processing to identify the object and then, determine the location of the object. This article also applies the Proportional Integral Derivative (PID) controller to adjust the speed of the vehicle’s engine according to a preset value to precisely track the desired object. The image processing part will apply computer vision to detect the object on Kit Raspberry Pi 3. Based on the input video, the Kit Raspberry Pi 3 will calculate necessary parameters for Kit Arduino through UART (Universal Asynchronous Receiver/Transmitter) communication standard. Then, the Kit Arduino will output PWM (Pulse Width Modulation) pulses from the PID controller to control motors for the vehicle to track the object when the object is moving in real time. The results in this article expose that the vehicle tracks the object with high accuracy.
