Vision based Navigation and Localization

For implementing higher level network task of maintaining connectivity in the deployed sensor network, the mobile node (iRobot Create) must navigate through the indoor environment. Visit tc.umn.edu/~bhat0089 for details.
Using only the laptop camera as a sensor we implemented the navigation and localization system.
Navigation uses vanishing point extracted from the corridor walls and edges.

Is it SLAM?

[vineetvb22]

@FORESTER2011 No. Its performing localization in a known map.

[vineetvb22]

We used the OpenCV C++ API. Edge detection and Hough transform based line detection were part of the algorithm.

[FORESTER2011]

@vineetvb22 so it only found the vanishing points of the video?

Did u use Matlab for this aplication?

[Handonam]

Are you using openCV to do this?

Huh, I was wondering why the hallways looked so familiar. Same university.

[LamotheExperience]

thats so cool.

[AlexHleb1]

Have you used a Hough transform in image analysis?

[JEIhrig]

I don't think a laser is involved, They seem to be using edge detection, focusing on lines that converge. (Lines formed by change in color in the image along walls and floor.)
