Outdoor Visual Localization: A Survey
Abstract
GPS-denied localization for the Soldier is paramount to military mission success. Sensors such as cameras and inertial measurement units are already ubiquitous in the aid of navigation. However, state estimation utilizing such sensors produces drift that currently must be squashed using absolute position measurements from unreliable GPS signals. To mitigate this uncertainty, we consider visual localization to provide an alternative global state estimate without the need for any current infrastructure. In this report, we investigate the current methodologies and capabilities, and review state-of-the-art approaches for visual localization and place recognition.
