To perform Automatic Referencing:
• Orient and process all the photographs that have marks that will be referenced. Check the quality of the orientation carefully (by checking Marking Residuals and Point Tightness etc.). The quality of the automatic referencing depends very much on the quality of the photo orientation.
• If only a subset of the project's Marked Points or Silhouette marks are to be referenced (such as in a non-one-sided object) put those points in their own layer.
• Open the Automatic Referencing dialog.
• The dialog will show the counts of the selected items in terms of how many references they currently have.
• Choose which items are to be referenced in section 1.
• For point referencing, decide which settings you want in section 3 (naming and processing status of referenced points).
• Press the Execute Referencing button.
• A progress dialog will appear as the algorithm runs and depends on the number of internal stages, the information in section 4 may update. When the process is complete you will be returned to the dialog and the change in the references will be displayed.
• Depending on the results displayed you may wish to rerun the referencing right away (in which case you press the "Unreference previous references" button, change parameters in section 2 and then press "Execute Referencing" again) or you may wish to study the results outside the dialog.
• Press Close on the dialog.
• Review the results of the referencing by studying the 3D Viewer and the Tables. If the result is not satisfactory you can reopen this dialog and press the "Unreference previous references" button to remove all the references just made. At this stage you may either change the parameters or study the project to see why the referencing might not have worked (inappropriate choice of search distance, poor photo orientation, poor mark placement, etc.).
