This PIX4Dmapper article explains how to access Rematch and Optimize feature and how this process affects the project.

Access: On the Menu bar, click Process > Rematch and Optimize (enabled once step 1. Initial Processing has been completed).
This process computes more matches between the images (and therefore more Automatic Tie Points), and reoptimizes the internal and external camera parameters. It is recommended 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 step 1. Initial Processing by re-matching images. For projects with more than 500 images, this process is unselected and disabled in the processing options.
Note: For large projects (more than 500 images), the Rematch and Optimize feature significantly increases processing time.
Important: Disabled or uncalibrated cameras will not be taken into account. For more information about how to calibrate uncalibrated cameras: How to manually calibrate uncalibrated Cameras in the rayCloud.
Warning:
- Results generated during step 1. Initial Processing are overwritten.
- The Quality Report is deleted. To generate a new Quality Report: Menu Process > Generate Quality Report.
- If step 2. Point Cloud and Mesh and step 3. DSM, Orthomosaic and Index have been processed, their result files will be deleted so these files should be backed up.
