Exploring Key Technologies in Autonomous Vehicles
Abstract: This paper dives deep into the technologies used in Autonomous Vehicles. The Global Positioning System (GPS) is a key technology employed by autonomous cars. It is a satellite-based navigation system that determines the exact location of an object. Another technology used by autonomous cars is cameras, which are utilized to detect road signs, identify red lights, and determine lanes on the road, among other functions. Typically, the digital images of the road are presented as unrelated pixels, and this data is structured for better utilization. The algorithm for lane detection interprets this data in four basic steps: preprocessing, feature detection, fitting, and tracking. The other two technologies detailed in this paper are RADAR (Radio Detection and Ranging) and LiDAR (Light Imaging, Detection, and Ranging). RADAR technology uses radio waves to identify objects on the road and is effective in any type of weather conditions. Contrastingly, LiDAR is a laser analyzing device that allows 3D mapping of the surroundings of the vehicle. Unlike RADAR, LiDAR utilizes lasers instead of radio waves.
