Augmented reality
- 4. On the other handVirtual reality provides full immersion. It does not “augment” reality.
- 9. Things needed to create Augmented reality:
1. Smartphone
2. Augmented Reality app
- 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
