Title: Rolling shutter
Post by: arafat on July 21, 2022, 10:28:53 PM

Metashape 1.8.4 allows regularized and full compensation.

I understand the difference between them, but I do not know how to choose between them,

1- Is Full always better than regularized ?
2- Is there a way (manually/automatically) to detect the need for compensation in images?

Regularized model is suitable for the case when the drone flies without turning the camera, i.e. during the shooting to a new route, the camera does not turn and the drone moves in parallel.
When using a Regularized, only two parameters are optimized for each frame: axis shift XY in the plane of the photo. When using the Full model, 6 parameters are optimized for each frame: shift along the XYZ axes and rotation along the XYZ axes.

Thank you for the explanation. Perfect!
