UAVs and Hyperspectral Imaging Unite

One of the things we’re seeing at Headwall is the proliferation of airborne applications. Multispectral suffers a bit with respect to hyperspectral (a handful of bands versus hundreds), which is why hyperspectral is winning the day.

Headwall's Field-of-View Calculator

When it comes to hyperspectral imaging, it isn’t always about the hardware. Before users even get to the stage of specifying a sensor instrument, they need to ask a few questions:

History Made, History Seen with Hyperspectral Imaging

As the market for hyperspectral sensing technology moves forward and advances, Headwall’s Application Engineering team has been able to gather a rare view into the past through the hyperspectral scanning of some of the most important historical artifacts and papers in the United States. For the first time ever, hyperspectral VNIR and SWIR imaging was conducted on key historical documents from the US Civil War period.

Hyperspectral Sensors for UAV Applications

The scientific research community is beginning to understand and embrace hyperspectral imaging as a useful tool for a few primary reasons. First, sensors are more affordable than ever. Originally conceived as multi-million-dollar ISR platforms for defense applications, hyperspectral imagers have been successfully ‘commercialized’ over the past few years. Scientists typically embracing RGB or multispectral technology before can now acquire hyperspectral sensors at affordable price points.

Headwall Remote Sensing Capabilities Seen “Down Under”

This past week, Headwall remote sensing team finished a productive week Down Under at the International Geoscience and Remote Sensing Symposium (IGARSS) in Melbourne, Australia.  The conference, organized by the IEEE, comprises a ‘Who’s Who’ across the global remote sensing community. But curiously absent were representatives from the United States, probably reflecting the topic du jour: sequestration. Imagine holding a geo-spatial and remote sensing conference and no one from NASA was able to attend?

Hyperspectral and Remote Sensing the focus at EARSeL!

Headwall's exhibition schedule kicks into high gear this month. First up is our appearance at the 8th Imaging Spectrometry Workshop, sponsored by The European Association of Remote Sensing Laboratories (EARSeL). This event gives visitors the opportunity to understand how hyperspectral imaging can be a valuable scientific tool for the research community. Precision agriculture, mining & minerals, petroleum pipeline surveillance, and disaster mitigation are just a few application areas and more are uncovered all the time as the technology becomes more affordable and easier to use.

Resource Exploration Using Hyperspectral Imaging

Headwall utilizes hyperspectral sensing technology as an essential industrial inspection platform and has made this technology increasingly valuable across a wider spectrum of commercial applications and most notably in the oil & gas industry.  Companies in the petro-chemical industry focus much of their financial capital and effort on efficient pipeline distribution, refinery operations, and environmental monitoring.  Not only for exploration, but also to keep to keep their refining and distribution infrastructure safe.

Hyperspectral Imaging - Next Generation Machine Vision Platform for Food Safety and Quality

Bosoon Park, author of this blog entry, works as an Agricultural Engineer on behalf of the USDA in Georgia. He has done extensive research on hyperspectral and Raman imaging as it applies to food inspection and agriculture. Author of numerous published papers on the subject, Bosoon will be co-presenting a discussion on hyperspectral imaging at the annual conference of the American Society of Agricultural and Biological Engineers to be held in Dallas July 30 through August 2.
