Achieving heat vision in OpenCV [closed]

Question

I am doing a project and my professor said "try to use heat vision as well". I am doing the whole project in OpenCV, and no way of dropping it.

I have no idea about how to do heat vision. I got only $50-$70 to spend for any device because rest is spent for other devices I am using.

So my question is, how to do heat vision? I am now identifying human using OpenCV with the help of videos captured by a normal webcam but heat vision also suggested by professor. Is there any way of doing heat vision in OpenCV? What kind of cjeap device do I need? Device should have a C# or C++ api as well.

Answer 1

Is your prof referring to using infra red combined with vision? In that case, all you need to do is remove the IR filter from your camera. Without this filter, infra red radiation goes through to the sensor and is clearly visible in the image. You can refer to this article for a start. I'm sure it's easier on a webcam :)
