Combined Visual and Infra-Red Search

February 3rd, 2010

I came across the following on the New Scientist website today.

Could seeing with heat and light simultaneously improve search and rescue missions? Nathan Rasmussen of Brigham Young University in Provo, Utah, thinks so. He has created a hybrid video system that integrates visible and infrared footage into a single shot. [Read more here...]

It definitely sounds like something that the aerial search community should keep their eye on…

As the article comments;

Tom Jensen, a spokesman for Washington Air Search and Rescue, an organisation that helps coordinate aerial searches, says that being able to see the output of both cameras on the same screen in real-time would be “pretty slick”

Next Year on the Re-Search Website

December 17th, 2009

2010 looks as if it is shaping up to be an extremely busy year for SAR work for me.

The SAR Bookshop will be opening in January with a few titles, and I will be building the number of titles in stock as time goes by. [I think I'm supposed to sell some as well, or something?]

SAR World will be starting up and I want to see that work.

And, of course, I want to continue to build this website after a great start [in my view] in 2009.

When I started out, I was very concerned that I might quickly run out of things to write about so I started a notebook – jotting down any ideas that came to me that I couldn’t write about there and then. Hopefully in 2010 I will get around to writing some more about some of these ideas;

  • Passing your SC Assignment
  • Search Research ideas, topics and projects
  • Searching in the Dark!
  • Mapping for SAR
  • Investigation for Missing Persons Incidents
  • Water Search
  • Aerial Search
  • “Cleared”
  • Health & Safety in Search
  • Post Traumatic Stress in SAR
  • “Patchwork” Search
  • Purposeful Wandering
    [a defence of; can you believe I might need to?]
  • Suicide
  • Dementia
  • Missing Person Behaviour
  • Search Theory

and much, much more.

If I have missed something out, or you want to see me write something earlier in the New Year rather than later – let me know!

How to improve the POD of aerial search for vulnerable missing persons

December 4th, 2009

Several years ago, in a blog long forgotten, I wrote a piece titled something like this one. It was inspired by the search for Fossett, and in particular, the use of volunteers to look through aerial photography and satellite  imagery via the Internet.

It started me thinking about aerial search – often seen and portrayed as this magic bullet  when it comes to missing person search [Understandable when you need to justify the expense!] But aerial search, like ALL search resources, is capable of missing.

For all the high-tech equipment onboard, including the FLIR (forward looking infra-red), it ultimately relies upon a human watching and interpreting the image on the screen.  Humans are fallible.  The image might be visible for a fraction of a second; if the operator is busy at that second, or tired, or for any other reason distracted at that exact point, the misper could be missed.

It happens.

However, unlike foot search, aerial searches tend to be recorded. This offers a second chance to find the misper [a very cost effective chance at that!]

My thought then was how many aerial searches are followed immediately by  a review of the “tapes” of the search?

If not done in-house, it would be possible to create a team of volunteers around the country, trained in reviewing such mission videos. After the aerial search the video could be spliced into sections, made available over the internet and volunteers could review the video [in slow motion!] and possibly pick up on mispers missed during the search.

Foot search teams still out on the ground could then be directed to check these potential hits.

It was just a thought then, and remains just a thought. For now anyway.
