Image based localisation and autonomous image assessment for a Martian aerobot

There is currently a strong demand for a range of intelligent vehicles to assist in solar system exploration and to pave the way for possible human missions. Balloon based planetary Aerobots offer a unique platform for carrying out remote science and can be used for a variety of applications such as high resolution imaging and rover guidance. However short to medium term missions of this type will be constrained in terms of power, communications, data storage and processing capability. To be of use, they must be able to localise and manage image data in an autonomous and intelligent manner, including prioritisation of images based on pre-defined science goals. This paper outlines a proposed scheme for a demonstrator testbed which will help provide and develop such a capability.
