xpano

Xpano is a tool for panorama stitching with focus on simplicity and ease of use, major features include:

• Auto detection of groups of images that can be stitched into panoramas
• Preview + zoom + pan of the computed panoramas
• Crop mode, boundary auto fill, selectable projection types
• Projection adjustments: pitch, yaw and roll
• Export of full resolution panoramas including exif metadata

Built with

The app uses the excellent OpenCV library for image manipulation and its stitching module for computing the panoramas.

Other dependencies include imgui, SDL, spdlog, Catch2, nativefiledialog-extended, alpaca, thread-pool, expected, Exiv2, multiblend, SIMDe and the Google Noto fonts.

Demo

Check out the demo on YouTube. This is how the app looks after importing a directory of 200 images.

Installation

Install directly from Flathub or the Microsoft Store:

Get additional packages:

• Windows and MacOS executables from GitHub
• Ubuntu packages from my Launchpad PPA
