I have successfully implemented the heat map, or false colour map. The quality of the resulting image isn’t fantastic, but it is quite good. I am confident that with proper post processing, such as interpolating, smoothing, etc, I can increase the quality even more.<\/p>\n

I implemented the heatmap by first converting the temperature information to HSV format (Hue, Saturation, and Value). I used the temperature value as the hue, and hardcoded the saturation and value. I then rewrote \u00a0some useful code that I found into processing and used it to convert the HSV value into an RGB value.<\/p>\n

The next goal will be to do some debugging with the Arduino sketch. At the moment I am printing the data out using the serial port, which is slow. This is causing the Lepton to go out of sync, and stop sending data. I need to avoid using the serial port at all until I am finished capturing images.<\/p>\n

I will then implement some post-processing techniques, as well as add the TFT screen and SD card to my project, and build a housing for it.<\/p>\n

The first few images have the colours reversed, red is cold, blue is hot, I corrected that for the rest of the images.<\/p>\n

I have created a github repo for all of my code and resources HERE<\/a>.<\/p>\n
