Hi, I’m Inigator
I Never Get Lost!
2. In the End ,We Tend To
Remember the Beginnings…
Inspiration:
13. To navigate, we need
For each image, we give it exact location
Created a database of all the names of the images and
their locations (so once user get a match, we find
his/her exact location
Navigate user from the detected current location to
destination
16. Train the computer to be smart
Collect images
Extract interest points
Make Inverted file index
(each interest point exist in
which images)
17. Give it an image to match
Extract interest points in the
query image
For each interest point
increase counter of existing
images
Image with the max number
is our first best match
22. Challenges Faced
Different images in terms of illumination, scaling, and
occlusion
Accuracy (Trade off between number of interest points
and speed)
Scaling (mapping)
Set exact location of an image
integration between process of image matching and
navigation
offline vs online files reading (use a server )
23. Future Work
Automatize
Adding images by the users to the server and adding the
nearest node for each image
Adding maps to the server and importing them in the
application
Looking at several possible paths at once
Dynamic map generation
Dynamic image collection
Gps switch mode when outdoors
