Digital Ad Wall at Traffic Signal By LuminoCoin


While several advances have been made in traffic light technology over the years nothing has really been done to improve the visual warning motorist get from the systems. Most countries use the standard three-light system for their traffic signals. Red means stop, yellow means prepare to stop / caution, and green means go, but the lights are usually six-inches in diameter and do little to catch the attention of motorist who are not focused on the road.

Three-light system replaces a new technology called “Digital Ad Wall” which allows highly visible hologram system. We are assumed to launch this concept at around 2020 in all over the Asian countries. The inspiration for this concept is based on the increasing road accidents in every year. Since traditional traffic lights are overshadowed by large electronic advertising signs, and the focus is lost at these intersections because the lights are less visible.

Future cars will be faster, than today’s machines. Therefore, the transition road to humans will be even more dangerous. So we are designing a new technology called “Digital Ad wall “ instead of the traffic light. This is absolutely a new high-tech development to control the road traffic — a traffic light influencing a driver psychologically and making an optical barrier.

Concept of hologram

A Hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics.

Virtual wall or Digital wall using Hologram

The system is a holographic Virtual wall, forcing the “reckless” drivers to stop at a red light. The principle is based on a laser projector that projects the images of moving pedestrians visible only to the drivers in front of it. In the night-time the hologram will be much brighter. But the pedestrians will see only the red stripes.

We are presenting the new wave of technology that will change how we view things in the new era. It will have tremendous effects on all fields of life including business, education, science, art and healthcare. To understand how a holographic projector works we need to know what a hologram is. Holography is the method we use to record patterns of light. These patterns are reproduced as a three dimensional image called a hologram

Digital advertising using hologram

3D holographic projection is a rapidly growing technology. A holoprojector will use holographic technology to project large-scale, high-resolution images onto a variety of different surfaces, at different focal distances, from a relatively small-scale projection device. So we can show advertisements on this digital walls when the signal is red (stop) along with the seconds reducing.

Digital holography refers to the processing of holograms with a digital sensor array typically a CCD camera or a similar device. Image rendering or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers three-dimensional surface or optical thickness images. Several recording and processing schemes have been developed to assess optical wave characteristics such as amplitude, phase, and polarization state, which make digital holography a very powerful method for metrology applications

Overview of holographic signal processing

A digital hologram includes not only the light intensity but also the depth information of the 3D (dimensional) object. That is, both the whole amplitude and the phase information are necessary to reconstruct the original 3D object, which are included in the interference pattern between the reference light and the object light. Since a digital hologram signal has much different characteristics from general 2D signal, a particular data processing technique is required. In spite, both have the same goal to acquire image information from 3D world and to display it as realistic as possible to human visual system (HVS). Thus, if the techniques based on the 2D-image are modified and some proper techniques for 3D image are added, they can be efficient enough to be applied to digital holograms.

Holography is a technique that enables a light field, which is generally the product of a light source scattered off objects, to be recorded and later reconstructed when the original light field is no longer present, due to the absence of the original objects. Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter like musical instruments or vocal cords, is encoded in such a way that it can be reproduced later, without the presence of the original vibrating matter.

A hologram is a cross between what happens when you take a photograph and what happens when you look at something for real. Like a photograph, a hologram is a permanent record of the light reflected off an object. But a hologram also looks real and three-dimensional and moves as you look around it, just like a real object. That happens because of the unique way in which holograms are made.
