Camera Location Accuracy

[rongilad]

Hi,

Does the accuracy value constrains the bundle adjustment to refine the camera location within the accuracy value range?

For example:
- Accuracy set to 0.1, will constrain the algorithm to refine the camera locations within 10CM from the initial value.
- Accuracy set to infinity, won't put any constrains for the bundle adjustment.

Correlator3D (another photogrammetry software) apply to this logic, this enable the user to apply 'direct geo-referencing' by limit the DoF.

Hello rongilad,

Camera location accuracy defines the weight of the coordinate values loaded for the cameras to the Reference pane compared to other elements (marker location accuracy, tie points and markers projection accuracy and etc.). It would be applied only for the cameras that are checked on in the Reference pane.

Thanks Alexey.

Is it possible to force the coordinate values to the origin value and use the alignment only for orientation?
I am looking for the optimal processing configuration for direct geo-referencing...

Hello rongilad,

You can use higher accuracy value to increase the weight of the camera locations coordinates, however, if it doesn't fit the measurements accuracy of the coordinate data, the alignment and optimization result may be affected.
