A presentation on Augmented Reality, The basic principles involved and various types of Augmented Reality. Presented on Govt. College of Technology, Coimbatore.
11. 1.Input 2. Marker Detection
Steps involved in marker based augmented reality
Using algorithms like Four corner test,
Size test
ThroughVideo
12. 3. Marker Identification and Rendering
Steps involved in marker based augmented reality
• The detected marker is identified by
matching it with other markers in a database.
• UsingTransformation Matrix 3D objects are aligned perfectly on the marker
14. Steps involved in marker less augmented reality
1.Feature point detection 2.Plane extraction
SLAM – Simultaneous
Localization and Mapping
Harris Corner Detector
15. 3.Tracking and Rendering
• the distance and orientation of the extracted
plane with respect to the camera is calculated
using various algorithms.(Eg: SIFT).This is called
Tracking.
• The 3D object is rendered on the plane using
rendering software.
18. Steps Involved:
• Position of the user is found usingGPS
• Information about position is gathered from the internet
• Gathered information is rendered on the screen using suitable rendering software
