Prioritizing Seafloor Mapping for Washington’s Pacific Coast

Prioritizing Seafloor Mapping for Washington’s Pacific Coast

Remote sensing systems are critical tools used for characterizing the geological and ecological composition of the seafloor. However, creating comprehensive and detailed maps of ocean and coastal environments has been hindered by the high cost of operating ship- and aircraft-based sensors. While a number of groups (e.g., academic research, government resource management, and private sector) are...

Sensor-Assisted Video Mosaicing for Seafloor Mapping

This paper discusses a proposed processing technique for combining video imagery with auxiliary sensor information. The latter greatly simplifies image processing by reducing complexity of the transformation model. The mosaics produced by this technique are adequate for many applications, in particular habitat mapping. The algorithm is demonstrated through simulations and hardware configuration...

Area Based Processing and Visualization for Efficient Seafloor Mapping

In recent years there have been remarkable advances in sonar technology, positioning capabilities, and computer processing power that have revolutionized the way we image the seafloor. The massive amounts of data produced by these systems present many challenges but also offer tremendous opportunities in terms of visualization and analysis. These systems produce massive amounts of data that mus...

Seafloor video mapping: modeling, algorithms, apparatus

This paper discusses technique used for construction of highresolution image mosaic from a video sequence and the synchronously logged camera attitude information. It allows one to infer geometric characteristics of the imaged terrain and hence improve mosaic quality and reduce computational burden. The technique is demonstrated using numerical modeling and is applied to video data collected on...
