3.
What is Augmented Reality ?
A combination of
a real world scene viewed by a user
And
A virtual scene generated by a
computer that augments the scene with
additional information.

4.
History of Augmented Reality
Sword of Damocles
The first AR device was born in the late 60s.

5.
Application of AR
Education
Medical
Entertainment
Military
Engineering
Manufacturing
Tourism

6.
Popular Example of Augmented Reality
Microsoft HoloLensPokémon Go

Augmented Reality vs Virtual Reality
System augments the
real world scene
User maintains a
sense of presence in
real world
Totally immersive
environment
Visual senses are
under control of
system

9.
How Augmented Reality Works ?
An AR system adds virtual computer-generated objects, audio
and other sense enhancements to a real-world environment in
real time.

10.
Software and algorithms
A key measure of AR systems is how realistically they integrate
augmentations with the real world.
The software must derive real world coordinates,
independent from the camera, from camera images.

11.
Image Registration
Image Registration uses different methods of Computer Vision.
Many computer vision methods of augmented reality are
inherited from Visual Odometry.

12.
Visual Odometry
It Consist of Two Part
The first stage
Detect
interest points

13.
Visual Odometry
It Consist of Two Part
The second stage
Restore
Real world

14.
Key Component of AR App Development
 Targets
 Content
 Texture
 Java Native Interface
 Occlusion
 OpenGL ES

15.
Hardware
 Two Camera for calculation of stereoscopic depth more easily.
 Enough Computational power.
 GPU & CPU Power as one can possible.
 Example:
Phone
Tablet
Eyewear
HMD(Head Mounted Devise)
