Structure from motion processing report

The report that can be generated at the end of a photogrammetric processing contains all the steps that the structure from motion software did for you.

It is very useful for controlling the whole process.

You can read in it:

• overlapping information about the images of the dataset;
• number of images processed;
• average shooting distance;
• Medium and effective GSD (Ground Sampling Distance);
• average value of the reprojection error;
  
• tie points (matching points);
• dense point cloud;
• calibration parameters of the cameras;
  
• GCP analysis;
   
• Error estimation based on Check Points;
• Faces of the triangular 3D mesh;
• Resolution of the texture of the orthomosaic;
• DEM resolution;
  
• processing times for each step;
• details of all the settings you used (very useful in case you need to redo the same processing, maybe after some time).

I guess that every structure from motion software allows you to generate a report.
It is usually a pdf file.

It’s not just stuff for an appendix of a technical report!

From this report you can check if everything was fine and, according to your plans, if the results were solid.
