Sentience

Last month I was experimenting with omnidirectional vision, using a christmas decoration as a mirror.

I've set up a microblog site for the Sentience project on floss.pro. It can be found here: http:/

Ok.

Raw images of the calibration dot pattern taken from the forward looking stereo camera on the GROK2

It looks like 2008 could be an exciting year. I'm in the process of building a new mobile robot

I've added a roadmap section to the wiki, with a list of things remaining to be done. Mostly

I've now made the DP-SLAM algorithm multithreaded, so that it scales well across multiple CPU

I've updated the source code licences to GPL version 3. The only part of the software which hasn

I should probably add a section to the Wiki regarding the blob method which I use for stereo

A program which I just found recently which may be useful is IFrIT http://home.fnal.gov/~gnedin/IFRIT

Suppose that two points in a pair of camera images have been found to correspond. Unless the point is

I've gathered more stereo data which can be used to test and debug the system. This time the

Some comments about storing 3D occupancy grids in an efficient way. http://code.google.com/p/

It is usually the case in machine vision that any image (or set of images) taken at a single point in

In the history of occupancy grid mapping there are many examples of robots travelling down corridors.

Some initial examples of the occupancy grid mapping algorithm. This is based upon DP-SLAM, but

I think opengl would be the best choice. It is fully supported everywere, should be quite easy to use

It may turn out that if robots are fitted with multiple stereo cameras that these will all be

The localisation and mapping is something which I'm doing at the moment. At present something

Thanks Bob. Your explanation was so useful. :)
