Blind Spot Detection Using Ultrasonic Waves

The region behind the car which are invisible to the naked eyes and to the side mirrors are known as Blind Spot. The vehicles present in the blind zone causes greater hindrance to the drivers and may result in accident. The existing blind spot techniques use RADAR technology which is much costlier. In this paper we proposed a technique which uses Ultrasonic waves to detect the vehicles present in the blind zone. This technique is much cheaper and it can produce greater accuracy than the existing methods. The detected vehicles are also displayed near the rear view mirror with the help of a camera and a LCD display device.
