The Cyborg Astrobiologist: Porting from a wearable computer to the Astrobiology Phone-cam

Planetary exploration by autonomous robotic systems cannot be carried out successfully unless significant testing of the underlying computer vision algorithms is performed. In our previous work, we have demonstrated the use of a wearable computer system, the Cyborg Astrobiologist, capable of testing computer-vision algorithms as part of semi-autonomous exploration systems at remote geological and astrobiological field sites (McGuire et al., 2004, 2005). In that work, we showed that the exploration system, which was based upon newly-developed'uncommon maps' and previously-developed'interest maps' (Rae et al., 1999; McGuire et al., 2002), could viably and robustly be utilized during remote field missions to localize interesting geochemical or hydrological features. Our system carries out the navigation process using the lower end of the spectral resolution, making use of three colour imagery to distinguish between regions of unusual colour. Navigation using higher spectral resolution spectrometry, for example, navigation based on mineralogical differences, will yield more interesting results but this is beyond the scope of the current work.
