Python and Java API / Correct use of selectMaskedPoints in python

« on: March 02, 2021, 09:16:21 PM »

Hi there,

I want to filter my dense point cloud with some masks (by file).

The entire workflow with adding masks before depth map & dense creation works, but I would like to create the dense cloud first.
As far as I understood, the process is to select points by mask and then export those.


I'm trying to use the method

Code: [Select]

Metashape.DenseCloud.selectMaskedPoints(camera, softness=4)

with camera being

Code: [Select]

camera = chunk.cameras
However, this gets me the following error:

Code: [Select]

TypeError: descriptor 'selectMaskedPoints' requires a 'Metashape.Metashape.DenseCloud' object but received a 'Metashape.Metashape.Camera'

Giving the argument of the dense cloud (object?) (chunk.dense_cloud) obviously returns
TypeError: selectMaskedPoints() missing required argument 'cameras' (pos 1)



Could you give me some pointers into the right direction?

Thanks!

Chris

Python and Java API / Import polygon on camera/image

« on: December 17, 2020, 06:44:20 PM »

Hi all,

I'm looking for an option to add a polygon to an image/camera in picture-pixel-"coordinates". (Not a shape file to the project/ortho)
Is that possible?

I've checked the Python API Documentation and only found the Mask import to a camera, but I believe that masks will work differently than adding a polygon to a picture, and thus to the project (ortho/point cloud).
If there are any pointers how I can deduct a polygon to the point cloud from an imported mask, let me know too.

Thanks a lot!
Just started out with Metashape regarding a research project.

Best,
Chris
