## About This Content
Photogrammetry Toolkit is a set of preprocessing and postprocessing tools
designed to help professional and hobbyist photogrammetry and computer vision
workflows.
## Frame Reduction
A tool for intelligently processing videos and image sequences for
photogrammetry purposes, removing images that are of low quality or too low
parallax to be useful. Also contains functionality to extract videos to image
sequences and to correct lens distortion.
Filtering steps can also be run from command-line.
## Mesh Optimization
The Mesh Optimization tool contains support for importing various mesh
formats, mesh simplification with the optimized Vrifier algorithms and tools
for orientation and reference scaling.
## Spherical Projection Mapping
A tool designed for calibration of 3d mesh to spherical image correspondence.
(360 equirect) This can be used for recovering the approximate original
photography position and orientation, and for projecting the spherical image
back on the original world geometry.

Note that Teatime Photogrammetry Toolkit does not feature actual functional
photogrammetry image bundling or mesh creation software.

This tool is a co-creation project with the Department of Geosciences and
Geography, University of Helsinki, Finland.
