Introduction

The concept of AR lies in blending together the real objects around us with virtual or imaginary ones that can be added dynamically to the world. Augmented Reality is picking up the heat nowadays. What if you could place a digital version of a scaled car right in front of you? AR or Augmented Reality is a live view of a physical world whose elements are enhanced by computer-generated information. There are some fundamental technologies that allow applications to understand the real world. Let's get familiar with some of them:

Motion Tracking

This allows the system to understand and track its position relative to the real world. The things which are near to our eyes look bigger in size compared to the things which are far away from our eyes. By exploiting the motion tracking and calculating the distance between the user and any point in space, the system can decide what should be the size of any imaginary object at that point in space.

Environmental Understanding

Environmental understanding simply means understanding the real-world environment by detecting feature points and flat surfaces. Using proper environmental understanding, one can place the virtual object in the real surrounding in order to analyze different aspects. It defines the boundaries, which are then later used to analyze the environment.

Light Metering

In the physical world, every object has a different amount of shining and has shadows of different lengths and shapes based on the light source's direction and intensity of the light near that object.AR application can utilize this light information to calculate the size and the direction of the shadow for any object at any point in space.

Surface Detection

Surface detection is one of the applications of AR. Surface detection lets learners place a 3D model of any object onto a tabletop or floor surface in front of them. They can then do whatever they want to do with objects like move, rotate, etc.

Benefits of surface detection

The major advantage of surface detection is that it places a real-sized digital model in front of learners. The parts of the object are developed all up to scale, which better prepares the learners to encounter the real object. Apart from this, learners can learn from anywhere just by placing the digital object in the surrounding.AR plane detection provides a unique learning experience.

ARCore

ARCore is a software development kit developed by Google for augmented reality applications to be built. It provides higher-level APIs for the application to interact with the real world. It works on the principles discussed below.

  • Motion trackingthis lets the phone understand and track its position relative to the real world. ARCore uses concurrent odometry and mapping to track the movement of the user in the real world.
     

Image Source

  • Environmental understandingallows the phone to detect the location and size of flat horizontal surfaces. It provides the boundaries of the plane by detecting the edges in the camera images.
  • Light meteringallows the phone to estimate the environment's current lighting conditions accurately. And finally, using this parameter to provide shadow and shine to the digital object to improve realism.

Applications of Surface Detection AR

Gaming and Entertainment

If you want to build a full-fledged 3D game with your own concept in the real world, then Augmented Reality's surface detection technology allows you to do so by analyzing various aspects of the game more precisely and with more advanced technologies.

Advertising

Product demonstration or product processing techniques displayed in the customer's environment is the best way to advertise a product and increase its sales.Good example is automotive industry.They are using AR to demonstrate their product with more customer engagement.

Fast Learning

In this era,everything is moving fast.You have to learn fast in order to implement fast.With AR surface detection, one can easily and fastly learn by placing the virtual object into the surroundings and then analyzing it.

Frequently Asked Questions

What is AR and what is its future?

AR is a live view of a real world whose elements are enhanced by computer-generated information. Tech giants believe that the next decade will be of AR and VR.

What is AR surface detection?

AR surface detection places a digital 3D model on a real-world flat surface, like a tabletop or floor. It has many applications in the gaming industry, in the advertising industry, and many more.

How can we start learning from surface detection?

Learners can learn anything by just placing anywhere the digital object into the surrounding. This will help them analyze the model very clearly and in a practical way.
