The record

Purpose: OpenPano is a C++ program for automatic panorama stitching, written from scratch without computer vision libraries.
Stitching methods: It offers cylinder, camera estimation, and translation modes, each with stated image capture or ordering requirements.
Algorithms: The project lists SIFT features, RANSAC-based homography or affine transformation, focal estimation, bundle adjustment, and straightening techniques.
Build: The README gives CMake and make build instructions for Linux, macOS, and WSL, plus a Visual Studio 2015 process for Windows.
Dependencies: Build dependencies include Eigen and FLANN, while libjpeg and CImg are optional image input/output components.
Usage limits: The README recommends manually downscaling images of four megapixels or more to save time.
Image requirements: The project says wide-angle images with heavy distortion do not work well unless camera parameters are used to undistort them.
Memory: The README describes memory consumption as large with the default libc allocator and says LAZY_READ can reduce it with a minor slowdown.
License: The repository includes the MIT License, which grants permission to use, copy, modify, distribute, sublicense, and sell copies subject to its conditions.
Warranty: The MIT license provides the software “AS IS” without warranty.
Windows support: The README cautions that the Windows build process may not work and invites pull requests to improve it.
Development status: The README lists Python bindings and macOS and Windows GitHub Actions among its TODOs.
Price from: Free
