1 Camera accuracy setting

A new POS accuracy setting has been added to the aerial triangulation (AT) settings interface. In versions 7.0.8 and earlier, the default X, Y, Z accuracy was 0.1 m. You can now adjust this based on the actual POS accuracy to improve AT accuracy.

Note: The X, Y, Z accuracies can only be set uniformly.

2 Pause Photo Loading feature

A new Pause Photo Loading option is available in the mark points interface. When checking control points, you can disable photo loading to avoid system lag.

3 AT constraints

Usage: For AT results generated from non-georeferenced data (relative orientation), a new Constraints tool is available under the Edit Control Points module. This allows you to add geometric or spatial constraints by linking control points to improve accuracy, correct deviations, or ensure geometric consistency. Create tie points by manually marking the same feature on multiple photos.

Steps:

Mark at least 2 tie points.
Click Add Constraints to open the Constraints interface.

Select the constraint type.

Supported types:

Scale Constraint: Define the distance between two tie points to correct the model scale (e.g., building width, paint mark spacing).

Planar Constraint: Force three tie points to lie on the same plane and align with a chosen coordinate axis plane (e.g., level ground or vertical wall).
