Multiple target tracking for intelligent headlights control

=======================================

Automatic light Dim Dip controller for Highways(NH)

           

Accidents in city areas during night times can be caused by over brightness of the vehicles.  So the Light’s brightness should be controlled (low beam) in the city areas. We have proposed an idea to change the beam automatically in the city areas.        

         

A good visibility of the road ahead is a major issue for safe nighttime driving. However, high beams are sparsely used because drivers are afraid of dazzling others. Thus, the intelligent automatic control of vehicles' headlight is of great relevance. It requires the detection of oncoming and preceding vehicles up to such a distance that only camera based approaches are reliable. At nighttime, detecting vehicles using a camera requires to identify their head or tail lights. The main challenge of this approach is to distinguish these lights from reflections due to infrastructure elements. In this paper we confront such a challenge by using a novel image sensor also suitable for other driver assistance applications. Different appearance features obtained from that sensor are used as input to a novel classifier---based module which, for each detected target, yields a degree of resemblance to a vehicle light. This resemblance is integrated in time using a novel temporal coherence analysis which allows to react in one single frame for targets that are clear vehicle lights, or in only a few frames for those whose type is more difficult to discern.

            Since this is a project, we used 5 Infrared Emitter and Detectors to determine the Car’s location.  When the Rays emitted by the source is obstructed by a obstacle (in our case, car has moved to next location), the change in signal from the IR Detector is fed to a microcontroller to indicate the change in location.  Once the change is identified the microcontroller checks whether the car has crossed the boundry, it turns on a relay for headlight glowing
