Python and Java API / Chunk AlignCameras in 1.6

« on: February 28, 2020, 12:52:07 PM »

We are updating our python script to 1.6 using the change log to tell us what has been renamed (no deprecation warnings...) at the bottom of this resource: https://www.agisoft.com/pdf/metashape_python_api_1_6_1.pdf

Maybe I am blind, but I cannot see anywhere in the change log that mentions a new parameter 'reset_alignment' to Chunk.alignCameras. To make matters worse, this new parameter defaults to a value that changes the result of the function rather than a value which would keep the result consistent with 1.5.

Python and Java API / Camera orientation

« on: November 07, 2019, 05:38:32 PM »

I am trying to get the direction vector of my cameras in what I think is the internal coordinate system, to go on to detect cameras that aligned facing upwards. Here is my current attempt:

Code: [Select]

for camera in chunk.cameras:
    if camera.transform and camera.selected:
        print(camera.transform.mulv(Metashape.Vector([0,0,1])).normalized())

I would expect the result in my screenshot to have a large -Z component, and low X and Y components since this camera is pointing straight down. However, it has quite significant X and Y components. I suspect I'm missing something obvious here, but any help would be appreciated.
