How to obtain coordinates from Autotags? - PIX4Dcatch

In PIX4Dcatch, the Autotag feature provides a fast and precise way to extract coordinates from automatically detected tie points. This workflow enables accurate measurement of multiple points within a project with minimal manual effort.

Instructions on obtaining Autotag coordinates:

  1. Evenly distributed Autotags across the project area.

         

        2. Activate the Tag Detection feature. 

            Access the capture screen, select the Tool icontools menu at the bottom right. Select the Tag Detection iconautotag icon. Enable the Detect Autotags feature.
