1. ECE 477 Digital Systems Senior Design Project  Spring 2006
Team 9 / Motion Tracking System
Project Overview
Camera module sends pixel data to microcontroller
Microcontroller calculates image difference data and runs through motion detection algorithm
Servo motors aim the laser pointer at the location motion is detected
CMOS image sensor sends pictures to the microcontroller
Microcontroller compares each picture to a reference frame to find new objects
Calibration routine available at start up
Potentiometers vary PWM width to aim servo motors
Values taken from each of 3 objects and used to calculate slope and offset values
Laser pointer mounted on servo motors
System will target the center of the largest object
Laser enabled only when motion detected
Used timer channels to create low frequency pulse waves
Servos responsible for aiming laser at target
LCD screen used to display messages to user
Can control system using push buttons
