CHAPTER 1 INTRODUCTION 1.1 Micro Air Vehicles (MAVs) Micro Air Vehicles (MAVs) are a class of Unmanned Air Vehicles (UAVs), significantly smaller than typical UAVs. UAVs are aircrafts without human pilot aboard. These are controlled either automatically by on board computers or through remote control by a pilot on the ground [3]. The modern aircrafts can be as small as 20 centimeters. The design features and the configurations of MAVs are different from that of normal aircrafts. The speeds of MAVs are very low and the size is less than 30 cm in length, width or height. With the development and comfort of electronics, smaller aircrafts, which can perform various tasks that were previously performed by manned aircrafts or larger UAVs, have been possible. Commercially off shelf components like motor, propeller, ESC, servo motor, battery, autopilot, data modem, camera (Payload), video Transmitter are tested and trained for performance and is then integrated with MAVs for autonomous flight operations as shown in Figure 1.1 [4]. Fig 1.1: Block diagram of MAV integration 1.2 Motivation In today’s world, MAVs equipped with digital cameras are increasing in number for real time applications. MAVs are widely used because of its small size, low weight, low cost and flexibility in design. The main purposes of MAVs are to provide video surveillance during military exercisers, firefighting, and weather monitoring, policing and border control [5]. However the video obtained by
