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 ReportMenu 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.
