Thanks John - The theory is that if we can detect kids overheating in the areas in front of stages we can get them medical help before it's too late. Severe overheating is a symptom of overdose for many of the drugs that are being taken at music festivals these days. This is not a law enforcement tool, but a health and safety tool.

I have firsthand knowledge of this application, but for different reasons.
I live in a region with high outdoor summer temperatures, and sports and heatstroke are common.
A local university has assembled a monitoring station that checks body temps of football players as a station in one of the running drills. It is essentially a booth that players must run through to be read.
They experimented with several camera locations, but found the only way of getting meaningful readings was to get very close to the players. It does work, though. Anyone with a high temp gets kicked to a cooling pool immediately.
Perhaps one of the thermal experts has a better answer, but I do not think you'll get the data granularity needed from an overview camera. I think it needs to be close to the subjects.
I think the only way it would work is if you had a close up thermal imager. Even then I think you would need a before and after picture to make a conclusion. The problem with Ectassy and Music is that people like to dance. This will throw off many of the existing thermal cameras on the market in my opinion.
Update - Like Brian said, you would probably have to go into a booth for a closeup scan. If you had to do that, you might as well just take their temperature.
Creat an iPhone app that takes their temperature and monitors it at these fests. Kind of humerous, but these things are becoming reality fast.
Another issue is what is the baseline? Everyone at a festival will be already warmer and excited just from the music alone. The body produces heat just by being excited.
The Discovery channel did a story on how much heat our body's produce from certian types of excitment. (sexual, visual, sound)
They got it already for drunks...
Great thread John...opens up new possibilities for the proliferation of the low cost uncooled microbolometer with thermography software.
"Severe overheating is a symptom of overdose for many of the drugs that are being taken at music festivals these days."
I'm not sure this is accurate. Severe overheating is a symptom of continuous activity (dancing;raving) without adequate cooling - not overdosing. And I've only heard this phenomenon associated with 'X' - never any other recreational use drug.
This link from DEA.org states: MDMA produces little or no hyperthermic response in humans at all doses tested (up to 2.0 mg/kg) under laboratory conditions (no change  or increases of less than half a degree C  were typical.)
Can you share some of the other 'many' drugs where severe overheating is a result of consuming them (while raving or not)?
Like many of the previous posters, I don't see a practical use of thermal cameras to combat this long-known issue. Deaths from MDMA-related use peaked in 2002 - primarily due to information campaigns and education programs targeted at the primary consumers (ravers).
Trust me on this one... I am involved in a lot of music festivals. We have lots of kids making their way to medical with symptoms of OD. The ones that are transported to hospital are typically severly over-heated. All that I have to go on is my on-the-ground experience at these shows.
If you think that there has been a decrease of the use of MDMA or any of the other multitude of synthetic drugs that are confiscated daily at these events, you are misinformed. These are not just 'ravers' coming to these events... this has gone main stream and when the 'non ravers' want to have the 'whole' experience at an EDM show, a lot of them will try something for the first time and have horrible reactions.
I have a practicle application... just don't know if there is a tool for this job.
This is far feteched. Everyone wears a BLE thermal patch on them that transmits the body tempature of them every 5-15 mins? or give them high tech wrist bands that do the same via RFID or WiFi. Then you would know no matter where they are on the grounds.
Anyone else have any direct experience using thermal to monitor / detect health issues with people? Let's focus back on that.
There is a rich history of FLIR thermal cameras being used to assess and measure human face temperatures in order to detect fevers associated with SARS and other illnesses. Ports of entry are the typical locations, and many of our readers who have travelled throughout Asia might be familiar with FLIR or other thermal cameras installed in the immigration halls at various airports. Travelers typically pass through a test station one at a time, pausing in front of a camera just long enough to have their temperature measured by a non-contact radiometric thermal camera. This application is well established and at least one paper indicates a high level of accuracy as judged by the results of secondary screening. Additional work in the veterinary medicine has demonstrated the ability to detect fevers in a wide range of animals.
The concert or music festival environment described by the poster is much less controlled than the immigration line. However, our collective experience says that thermal imaging will still be viable even in a crowded scene as long the camera can view the subjects with enough resolution to accurately image the face and perhaps other exposed skin. It is easy to imagine a camera positioned to view the faces of the crowd at the front of the stage and being able to identify those that have higher skin temperatures. Color palettes or isotherms with temperature ranges of interest would greatly ease the assessment process. I am not qualified to speak about the physiological processes and symptoms of overheating, but let me add that not only can you visualize relative differences in subject temperatures, you can also detect the presence or lack or perspiration. I mention this because it is my understanding that those suffering from heat stroke stop perspiring.
Sounds like a great application that should be pursued.
