Robust navigation for mobile robots over long distances requires an accurate method for
tracking the robot position in the environment. Promising techniques for position estimation …

This paper studies the accuracy of position estimation for groups of mobile robots performing
cooperative localization. We consider the case of teams comprised of possibly …

As the main observed illuminant outdoors, the sky is a rich source of information about the
scene. However, it is yet to be fully explored in computer vision because its appearance in …

This paper discusses the basics of design for testability. A short review of testing is given
along with some reasons why one should test. The different techniques of design for …

A key problem in widely distributed camera networks is locating the cameras. This paper
considers three scenarios for camera localization: localizing a camera in an unknown …

Skylight polarization is used for navigation by some birds and insects. Skylight polarization
also has potential for human navigation applications. Its advantages include relative …

The polarization compass is an autonomous, long-endurance compass technique that is
intended for enhancing the environmental suitability of the integrated navigation systems …

This article presents the development of an image-based sun position sensor and the
algorithm for how to aim at the Sun precisely by using image processing. Four-quadrant light …

For celestial measurement, it is difficult to enable a single optical system to image and
measure both stars and the sun due to the vastly different light intensity of targets and the …

This paper introduces an autonomous navigation system suitable for supporting a future
Mars Science Helicopter concept. This mission concept requires low-drift localization to …
