AutoGR Bridge

A QGIS plugin that connects AutoGR-Toolkit to QGIS for automatic image georeferencing.

Select a reference raster (or a canvas snapshot), add your dataset images, choose a feature descriptor, and click Run. AutoGR-SIFT launches automatically, and when processing finishes the georeferenced results are imported back into your QGIS project.

You can find the latest version, you can visit the official QGIS Plugin page or directly from your QGIS.
