FeverDetector

Detect people who have fevers with FLIR Lepton + PureThermal Smart I/O Module on Linux or Mac

Hardware requirements

FLIR Lepton 2.5 or 3.5
PureThermal 1/2/Mini
A USB cord with appropriate length

Linux Platforms

PC/NB running with Debian/Ubuntu distributions.
Raspbian (tested) on Raspberry Pi 3 model B+ or above.

NOTE Linux (< 4.0) + V4L (and OpenCV)

Linux Kernel versions less than 4.0 don't match the UVC format UVC_GUID_FORMAT_BGR3 with V4L2_PIX_FMT_BGR24. Applications that use libv4l and depend on the BGR24 format (such as the VideoCapture module of OpenCV) will not be able to use this format. Instead, they will use software scaling to convert RGB565 into RGB24/BRG24, at a loss in color resolution and with expense to CPU.

MacOS

If you are using Mac, make sure that homebrew is installed.

Quick Start

Clone this respository by git clone https://github.com/MakeHub-tw/FeverDetector.git
Execute setup_linux.sh to set up libraries and dependencies, or setup_macos.sh if you are using a Mac.
Execute setup_python.sh to build the execution environment. Or optionally, you can setup your own virtualenv first.
Go to src folder, and launch the application by python3 FeverDetector.py or ./FeverDetector.py
Click Start IR Camera Feed to process the camera stream.
