I've done this before with success using the Photosynth Toolkit (http://www.visual-experiments.com/demos/photosynthtoolkit/), except instead of a drone I was hanging my head out of a small plane taking pictures of the downtown area of a small town. You could also check out Visual SFM (http://ccwu.me/vsfm/); I haven't used it but it seems to be another tool ...
You can use the QuickMap Services plugin to get aerial background maps in QGIS. You have to activate additional sources with Web -> QuickMapServices -> Settings, More services, Get contributed pack. BTW the Openlayers plugin still works for me in QGIS 2.14. You might need to update the plugin to version 1.3.6. Apart from the plugin, many surveying ...
You can add Google Aerial basemap to you QGIS canvas using Google TMS. Save the following as .xml file and load it as a raster in QGIS <GDAL_WMS> <!-- Data is subject to term of use detailed at http://code.google.com/intl/nl/apis/maps/terms.html and http://www.google.com/intl/en_ALL/help/terms_maps.html --> <Service name="TMS"> ...
Whenever you handle large amounts of raster-data it is comfortable to use a raster-catalog. The raster-catalog is an option of the file-geodatabase format. You can create the database via right-clicking on your folder in the catalog-window where you want to have the database, just choose "new" -"file-geodatabase". Then choose "new" - "raster-catalog". The ...
I think the closest available tool is the GRASS tool i.points.auto which aims to automatically generate ground control points to geocode rasters. It is available for GRASS 7.0 so it may also be available in QGIS 2.14. Otherwise you may need to use GRASS GIS 7 which already comes bundled with QGIS 2.14.
I think a way to do this is VisualSFM to do the matching of the photos (the stronger the GPU the better) and creating a dense point cloud and MeshLab to create a textured triangulated model from the point cloud. VisualSFM: http://ccwu.me/vsfm/ http://ptak.felk.cvut.cz/sfmservice/websfm.pl?menu=cmpmvs (cp. especially the 'Technology' site and the paper ...
Something is way off with your dY values. If I understand correctly, your image is just a scan from a paper map, but it is for some reason defined with EPSG: 3857. I would suggest resetting the georeferencer, define the image CRS to be the same as you project (4326 in this case) and the proceed to georeference it again.
A few days after posting this question I finally found the procedure the ESRI rep had mentioned. Here is the link https://www.arcgis.com/home/item.html?id=133a6dc35a5f45d094b73effa68fefcb It is not the best solution but it is available if need be.
