**Discorpy** is an open-source Python package for camera calibration and distortion
correction with sub-pixel accuracy. It calculates parameters of correction models
using a grid pattern image. The package mainly implements methods published in
[Optics Express](https://doi.org/10.1364/OE.23.032859). It provides methods in
a full pipeline of data processing. From version 1.4, perspective distortion
correction was added to the package.

Major updates
=============
- 25/02/2021: the package name was changed from Vounwarp to Discorpy. The old-name
package is still available at https://github.com/nghia-vo/vounwarp
and installable using conda-forge channel: https://anaconda.org/conda-forge/vounwarp
- 21/11/2021: Version 1.4 was released with new features: perspective distortion
correction, pre-processing methods for line-pattern images and chessboard images.
Features
========
- Pre-processing methods for: extracting reference-points from a dot-pattern image,
line-pattern image, and chessboard (checkerboard) image; grouping these points line-by-line.
- Processing methods for calculating the optical center, coefficients of polynomial
models for correcting radial distortion, and parameters of a model for correcting
perspective distortion.
- Post-processing methods for: unwarping lines of points, images, or slices of
a 3D dataset; and evaluating the accuracy of the correction results.
- Some methods may be useful for other applications:
* Correct non-uniform background of an image.
* Select binary objects in a certain range of values.
* Unwarp slices of a 3D dataset.
- Summarized by an AI chatbot: "It is a Python library for camera distortion
correction that is designed to be easy to use and accessible to both computer
vision experts and novice users. The library provides a simple API for
correcting lens distortion in images, and it is based on the popular NumPy
library for numerical computing. Discorpy also has good documentation and
examples to help users get started with the library".

Demonstrations
==============
- https://discorpy.readthedocs.io/en/latest/usage.html#demonstrations
- Apply to a visible dot-target collected at [Beamline I12](https://www.diamond.ac.uk/Instruments/Imaging-and-Microscopy/I12/Detectors-at-I12.html),
Diamond Light Source, UK:
- Apply to an X-ray dot-target collected at [Beamline I13](https://www.diamond.ac.uk/Instruments/Imaging-and-Microscopy/I13/Diamond-Manchester_Imaging_Branchline/Facilities_and_equipment_Imaging.html),
Diamond Light Source, UK:
- Improvement of a tomographic reconstructed image after distortion correction.
+ Before the correction:
+ After the correction:
- Apply to a hazard camera of the [Mars Perseverance Rover](https://mars.nasa.gov/mars2020/multimedia/raw-images/).
Details of how to estimate distortion coefficients of that camera without using
a calibration target are shown [here](https://github.com/DiamondLightSource/discorpy/blob/master/examples/Perseverance_distortion_correction/Distortion_correction_for_Perseverance_camera.md).
