Still working on the Sentience stereo vision project. I'm still making refinements and improvements, mainly on increasing the accuracy of the depth maps. I'm really quite pleased with some of the recent changes. Although there is still quite a lot of "noise" in the depth images detection of objects or people seems very reliable even under poor artificial lighting conditions.

I'm trying to get the depth maps as accurate as they can possibly be, so that the quality of occupancy grids produced from the maps will have a similar or even better level of accuracy. There's nothing particularly special about the webcams which I'm using. There is no special frame capture synchronisation or colour correction, but I can still get reasonable results. This should mean that a sophisticated three dimensional perception system can be built using very cheap "off the shelf" hardware.
