Mosaic Based Navigation for Autonomous Underwater Vehicles

We propose an approach for vision-based navigation of underwater robots that relies on the use video mosaics of the sea bottom as environmental representations for navigation. We present a methodology for building high quality video mosaics of the sea bottom, in a fully automatic manner, that ensures global spatial coherency. During navigation, a set of efficient visual routines are used for th...

Precision Navigation and Control for Autonomous Underwater Vehicles

Navigating Autonomous Underwater Vehicles

Autonomous Underwater Vehicles (AUVs) are powerful tools for exploring, investigating and managing our ocean resources. As the capabilities of these platforms continue to expand and they continue to mature as operational assets, navigation remains a fundamental technological component. This chapter presents a road map for the vehicle designer to aid in integrating the latest navigation methods ...

Autonomous Underwater Vehicles

Navigation is one of the most critical factors in determining the operational suitability of any unmanned vehicle for its designated environment. In fully autonomous vehicles, due to the lack of a human operator to perform the navigation task, there is a fundamental requirement to incorporate estimation techniques that can provide the desired information necessary for navigation. Such informati...

Application of robust, high-accuracy positioning for autonomous ground vehicles

In this paper we review the need for robust, high-accuracy positioning for path guidance in the presence of large structures (such as buildings and trees) and for the integration of sensor data. Such capability is necessary in many applications that require precision over vast areas of operation. We find that unless integrated tightly, combined INS/GPS systems diverge significantly when line of...
