The HDRI Calibration Tool was designed to automate the process of merging multiple LDR images together and generating an HDR image. It is not a standalone app, and is meant to be used alongside the app Radiance. This is an entirely free,open-sourced application developed by a small group of computer science students.
To read more about the process of generating an HDR image from LDR image input, see the research paper by Clotilde Pierson here.
If you have any difficulty using the application, please check out our github Wiki for more information.
Additionally, the GitHub Wiki includes OS-specific information regarding installation, troubleshooting, and setting up a development environment to make changes to the app.
A step-by-step guide on using the app is also on the wiki, with a formatting guide for the calibration and response function files.
It also includes information about the development of this project including libraries used, more info about the radiance_pipeline submodule, using Figma to prototype and test design on users, and documentation for functions in some of the files.
Prerequisite: HDRGen, Radiance.
This app has been tested on Windows 10. For Windows users, unzip the code, and in the root directory, run the executable "HDRICalibrationTool.exe". Please do not remove this file from this directory, else it will not run. Feel free to make a shortcut of the executable and move that to a more accessible location.
Note that you will need an SSH key set up in Github to get the submodule. You may also need to install qt6-base or qt6 from your package manager software.
$ git clone https://github.com/XiangyuLijoey/HDRICalibrationTool.git
$ cd HDRICalibrationTool
$ git submodule update --init --recursive --remote
$ pip3 install -r requirements.txt
$ python3 main.pySee the wiki
For example input LDR images, camera lens settings, calibration files, response function files, and output HDR images, see the \examples directory in the root directory.
