I'm Dave Barnes and I'm a professor of space and mathematics in the Department of Computer Science, which is part of the Institute for Mass Physics and Computer Science. We're going back to sort of pre-2003, Arivon in Beagle 2, was primarily with the robotic arm and with the stereo camera system. Post sort of Beagle 2, we got involved with the same sort of colleagues and those colleagues actually lead the panoramic camera instrument for the X and R's mission. Pancam is a multi-special stereo camera system, it also has a high resolution camera. One of my really key research areas is making sure that we can reproduce the natural colours of models. It's like any camera system you need to do what we call a white balance on it so that the colours are correct. Key to that is having a calibration target. This is a lick of prototype and this will actually sit on top of the Rover deck so it can be the flight model of this will go to Mars. Mars has a very high ultraviolet irradiation which does bleach colours. We realise actually that perhaps a way to pursue this was to use effectively stained glass. We all know going into medieval churches etc and looking at sort of stained glass windows. As far as we are able to tell the colours are as good today as they were many hundreds of years ago. I think it has its own passport. It's been out to places like Svalbard, our camera system. It's been to Iceland, it's been out to the Atacalmides, we've even taken to Carac Bay which is sort of 10 minutes away from here. It provides a rich set of images that we capture under different lighting conditions, different terrains that help us actually develop our algorithms. We can also put these cameras actually on our own half scale exomars Rover within our padlam, our planetary and our long terrain laboratory. We have our sort of Mars simulant terrain learning how we're going to operate the Rover in the context of stopping and taking images, spotting science targets and then traversing over to them. You
