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;
    Images information in processing report
  • 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.

Ciao!
