This feature reoptimizes the camera positions and the internal camera parameters. It does not compute more matches between the images, therefore, it is a fast step that improves the accuracy of the project.
It should be used when changes have been applied to the project after step 1. Initial Processing has been completed. Such changes can be:
- Adding GCPs.
- Adding Manual Tie points.
- Adding Check points.
- Changing coordinate systems.
- Disabling images.

Rematch and Optimize
This feature computes more matches between the images (and therefore more Automatic Tie Points) and reoptimizes the internal and external camera parameters. Therefore, it takes more time than the Reoptimize feature.
It is recommend to use it:
- After manually calibrating cameras that were not initially calibrated.
- For difficult projects where few matches were initially found.
- To merge individual projects that do not share common images.
- To optimize the step 1. Initial Processing by re-matching images. For projects with more than 500 images, this option is unselected and disabled in the processing options.
