Reprojection error

How can I find the mean reprojection error in the quality report of Pix4D Matic after I finish the AT task.

Hi @jack.zhang you can find the reprojection error for all marked tie points in the Tie points table in the quality report. See an example of the ground control points table in the screenshot below, and the quality report will display a similar table for checkpoints and manual tie points if you have any in your project.
