Investigate Point Cloud gethering Systems

[victorkaminskiy]

Examine Kinect possibilities. Compare solutions provided by Microsoft and Asus. Consider alternative approaches such as Stereo Camera

[DmitryZakharov]

The main pitfall of the approach is that the Kinect and I believe Asus too are very vulnerable to direct day Light. There is a very strong interference with the natural IR. Here is the example of outdoor capabilities: http://www.youtube.com/watch?v=rI6CU9aRDIo As far as I remember the competition takes place outdoor. this is the first observation, further investigation is in progress.

Let's take a look at this: http://blog.martinperis.com/2012/01/3d-reconstruction-with-opencv-and-point.html Maybe it's better solution than Kinect

http://pointclouds.org/about/ - interesting library

[DmitryZakharov]

that's exactly the lib with which we could create the corridor model.

[DmitryZakharov]

Already working on the direction of using a stereo camera.

[DmitryZakharov]

Here is an example of what can be done by two simple webcams. the result is rather bad. However, it has been done with little light. I think it may perform better if there is more light. What I don't want to do is building a solution and trying to make it work. We will waste our time on it and won't have time to work on the core problem. We need to look for a decently working solution.

http://www.cvlibs.net/datasets/kitti/ Samples of Stereo Vision. Probably with a "good" set of wide-angle cams we may have an acceptable result at the end. Further investigation required.

Will also spend some time on this, as a part of my task with downward camera. I think it will be really cool if will be able to use only cameras for navigation.

I think this can be useful: https://code.google.com/p/opencvstereovision/

yeah, I saw it yesterday, the result didn't impress me at all....
