An autonomous vehicle or self-driving car is an automobile that has the ability to navigate without any human intervention. The continuing advancement of technology has made autonomous vehicles a reality, and the development of “ machine vision ” has been a fundamental component to this reality. The driverless vehicle utilizes several systems to function; a GPS unit, an inertial navigation system, a range of sensors including laser rangefinders, a radar, and video equipment/technology. Before the vehicle makes any navigation decisions, it must initially build a map of its environment and accurately localize itself within that map. The most commonly used sensor for building that said map, are laser rangefinders and cameras. A laser rangefinder uses swaths of laser beams to scan the environment, and then calculates the distance of nearby objects by measuring the time it takes for the laser to travel to the object and back. The vehicle then filters the collected data from each sensor and creates a comprehensive map, which can then be used for path planning. Moreover, for the vehicle to know where it is located in relation to other objects in the map, it must use its GPS unit, inertial navigation unit and again its sensors to precisely localize itself as well as build three dimensional images of its environment. Afterward, the vehicle determines the most optimal path to take, and the control system can now maneuver the vehicles steering, brakes, and acceleration. This process of localization, mapping, obstacle avoidance and path planning is a continuing cycle until the vehicle reaches the desired destination.
