Internet of Things (IoT)
are forced to track all vehicles at many strategic locations to identify or find where the
criminals are. This kind of tracking is possible only if the police personnel are able to see
the driver/passengers who are traveling in a vehicle from outside.
For seamless visual tracking of passengers traveling in a vehicle, the visual light transmission (VLT) and visual light reflectance (VLR) values of the glass windows used in the
vehicle should be at a particular value. All vehicle manufacturers follow certain standards.
But the vehicle owner/user generally buys window tinting films from grey market and
pastes the same on the glass windows which in turn will hamper the visibility, thereby
preventing the law enforcement authorities from having the clear vision of those traveling
in the vehicle. In many cases, the tinting films are such that the passengers traveling inside
the vehicle can clearly see the outside world through the glass window while the outsiders may not be able to see who are all inside the vehicle. To regulate this, law enforcement
authorities in each country/state have prescribed certain threshold values on the VLT/VRT
value to be used after fixing the tinted films on the glass window.
In this chapter, we propose a video-based automatic technique that will not only identify
the vehicle (say, car) but also estimate the VLT percentage. If the VLT level is below the
prescribed limit (say, 35%) then the envisaged system will automatically identify the vehicle number plate. Then the identified vehicle registration number will be searched in the
appropriate database to locate the violator’s contact details. Subsequently, an automatic
message will be transmitted to the concerned person along with the date, time, and place
of violation. Thanks to IoT (Internet of Things), the proposed system not only identifies
the tint level violation but also provides documentary evidence and communicates the
same to the relevant person.
1.2 Literature Survey
“Window tinting” refers to the methods used to block certain levels of light from passing through the glass window of vehicles. Most of the window glasses in the vehicles are
coated or treated in order to filter the harmful ultra-violet (UV) rays entering the vehicle.
The window tinting has various other effects. (1) Dark tinting will reduce driver’s vision,
particularly while driving at night. (2) Tinting windows will distort the vision of aged
people and people with problems with eye sight. (3) If anyone wears polarized sunglasses,
it will produce some visual patterns on the window. (4) Over a period of time, tinting can
even lead to bubbles, peel, or develop cracks that may bring down the value of a vehicle
and it general look. (5) Many vehicles come with window glasses that are engineered in
such a way that in the event of an accident, they will “break away.” At times, the tinting
material will prevent windows from breaking during accidents. This in turn can cause or
even worsen injuries during accidents.
Computing systems are generally introduced wherever speed and accuracy is needed.
A typical computing system works on the principle of input–process–output. In the conventional computing system, the input is keyed in by human beings (as we see in many
reservation counters, banks, etc.) and the software algorithm running at the computing
system processes the inputted data and produces an output. In general, these outputs
are displayed on a display device such as a monitor or printed using a printer. If people
responsible are lethargic or lazy, often the speed and accuracy of the computing system is
lost. However, IoT systems help us to resolve this issue.
