Thermal Image Analysis

A tool for analyzing and annotating thermal images.

This repo relies on the thermal_base python package for image decoding and manipulation backend.

Quality check

Features


Main menu

Spot marking, line measurement and area marking

  • Extract the temperature values at marked spots
  • Plot temperature values along the marked line(s)
  • Get min, max and average values of marked regions

Generates a plot for line plots and a table for measurements in the marked regions.


Markings on the image.


Plots and measurements.

ROI scaling

Scale the entire image based on values in the marked region. Use to enhance low contrast areas.


ROI scaling interface.

Change colormap

Change colormap to one of the following options:


Change colormap.

Emissivity scaling

Change reflected apparent temperature and emissivity of marked region.


Emissivity scaling interface.

Save data

Image can be saved with or without markings, plots and values. Custom savefile(.pkl) saves all data and can be used to revive the previous session. New supported save extensions are :

  • CSV : Saves thermal values of a thermal image in Kelvin as a CSV format.
  • TIFF: Saves thermal values of a thermal image in Kelvin as a TIFF format.


Saving process.

Installation

  • Run installation once with pip install -r requirements.txt
  • Install exiftool

Usage

  • Run the program with python main.py
  • Select the original thermal image file or the custom saved .pkl file. (Find some samples in sample_images)
