Title: Camera calibration
Post by: Abb on April 18, 2019, 07:03:05 AM

Hello all,

I have a question that occupied my thought:

When PS do the calibration, this calibration parameters are fixed for all photos equally or for each photo is different parameters?

Thank you for your reply.

Hello Abb,

By default all cameras in the same calibration group share the same parameters. In the latest version of Metashape it is possible, however, to select, which parameters will be estimated individually for each camera via "photo-invariant parameters" dialog of the Camera Calibration window.

That's great Alexy.

Is the "via "photo-invariant parameters" dialog of the Camera Calibration" operation possible via python as well?

I'd like to solve the camera intrinsics for each camera individually....I realise this will take longer.

Thanks,
Matt

Hello Matt,

You can define the list of photo invariant parameters for the certain sensor using the following code:

Code: [Select]

sensor.photo_params = ['F', 'Cx', 'Cy', 'B1', 'B2', 'K1', 'K2', 'K3', 'K4', 'P1', 'P2', 'P3', 'P4']It is similar to sensor.fixed_params list definition.
