Import orthomosaic and produce accuracy report based on GCPs

I would like to know if it’s possible to bring an already finished ortho into Pix4D and then generate a horizontal accuracy report based on a set of GCPs.


Hi Mark,

You cannot import in Pix4Dmapper an orthomosaic which was processed externally. In order to georeference an orthomosaic based on GCPs, you need to process the project from scratch (step 1, 2 and 3) and use GCPs as recommended in our article: 

One workaround would be to use QGIS (download link here: for importing the orthomosaic and georeferencing with GCPs.
