What is Augmented Reality? Indirect view of real world

Augmented by a computer generated graphic, video, image,

object etc

TECHNIQUES: MARKER BASED

MARKER LESS

Inspecting a virtual bunny on top of the user’s

hand from different viewing angles.

WHAT IS A MARKER?

•ANY IMAGE THAT CAN BE DETECTED BY THE

CAMERA

•SHOULD HAVE DISTINCT FEATURES AND

PATTERNS

Why Use Augmented Reality In

Education?

• Simplify concepts

• Enhance learning

• Ease and efficiency

• Less cost

• Can be employed in rural areas

• Make learning fun

• Introduce students to technology

STEP 1 : DIVIDE THE IMAGE IN

REGIONS

STEP 2 : DETECT EDGELS IN THE

REGION

STEP 3 : FIND SEGMENTS IN THE

REGION

STEP 4 : MERGE SEGMENTS INTO

LINES

STEP 5 : EXTEND LINES ALONG

EDGES

STEP 6 : KEEP LINES WITH

CORNERS

STEP 7 : FIND MARKERS

Disadvantages overcome by this

algorithm Speed of detection

Detection of markers having an edge or

corner (partial) occluded.

Performance under changing or not

homogeneous lightning conditions.

Applications

MANUFACTURING

ENTERTAINMENT

MEDICAL

EDUCATION

AERONAUTICAL

DEFENSE

AND MANY MORE
