Automatic beams detection used for LiFi car-2-car communication

The car-2-car communication feature is a must for the next generation of cars. Such a functionality will increase the road safety by enhancing the drivers awareness about road conditions and eventual obstacles. It can also be used to inform the cars coming from behind about risky situations in order to trigger early avoidance actions (e.g. breaking). The paper proposes an alternate solution to the WIFI technology which is the most studied for this purpose. The proposed solution is based on Light Fidelity (LiFi) and analyse the feasibility of such a system, from image processing point of view during automatic beams detection. The solution consists of two parts: the information sender, which is the car’s LED beams, and the information receiver which is an onboard camera running a special software. This solution has the advantage of using already available car’s hardware with small adaption, and only integrate the new software.
