The growing world of themal imaging…

The image is a thermal picture of me taken with aFlir Camera. It shows a heat map of my face. Yesterday I was watching the news, and one of the things I have talked about for the past three years was demonstrated by the police in Northern Virginia. A man wandered away from an Alzheimers Unit. Worrisome, and sadly happens on occasion, but once wandering away, the person may not be able to find their way back. The hard part of this particular story comes next. The retirement facility where the person lived, is near a state park with lots of open lands and dusk was falling. By the time the frantic staff got ahold of 011, it was dark, and they were unable to find the person.

Missing people at night can be doubly bad. So the police used technology to solve the problem. By loading a FLIR heat camera module into a drone, they have the capability of seeing warmth at night. The human body is more ware than plant life. They were able in less than an hour to see, find and return the lost patient to the facility. As drones gain longer and longer flight time, they will be able to be used on many more search and rescue missions. Today you can drone with the Fair modules (night vision), Sonar, 4k camera and Lidar (a form of mapping radar).  The limit on larger drones of flight time is somewhat problematic, but you can use computers to design a search grid that allows you to cover much more ground with a drone that you ever could with people.

There are many more uses for thermal images by the way. One of the easy ones is simply walking around your house and seeing in the winter where cold air (blue) is leaking into your house. Or in the summer where hot air is leaking into your house (red). Simply pointing the thermal camera gets you the images of what you are looking at and the current temperature. You can also get laser thermometers that allow you o stand away from an object and determine its temperature as well. Like, when your car is overheating, you really shouldn’t touch the radiator cap. Yes, the rule of thumb is to check the radiator fluid level, but that cap is hot. Using a laser thermometer you can find out just how hot, before you burn yourself!

    • There is and there isn’t. So the thermal imaging systems use a len’s designed to capture IR. Facial Recognition can use any camera including IR, but it is more an AI or ML driven pattern matching system.
