Python and Java API / Build dense cloud for sub-region
« on: September 19, 2023, 01:15:40 AM »
Hi. I'm working with a pair of satellite stereo images which are quite large and I would like to limit the processing (mainly dense cloud building) to a sub-region. Is there a way to do this in Metashape?

General / Coordinate System greyed out in Export Points
« on: August 01, 2023, 06:19:26 PM »
Hi. I've built a dense cloud which I now would like to export but the Coordinate System drop down menu is greyed out and I can't choose the right system. If I leave it as is, it will export an empty las file. Can you help? Thanks

Python and Java API / Create chunk copy
« on: June 16, 2022, 10:15:52 PM »
Hi. I'm having trouble making a copy of the chunk in my project. I'm using the following:
chunk2 = chunk.copy
But when I reopen the project in the GUI, chunk2 is not visible.
Can you help?

Python and Java API / GPS/INS offset parameters
« on: June 10, 2022, 11:12:04 PM »
Hi. Once again, I'm looking to code in Python the parameters of a GUI window, this time the GPS/INS offset parameters of the Camera Calibration window. Does anyone have python code for this? Thank you.

Python and Java API / Reference Settings parameters

Hi. I'm trying to implement in my Python script the various parameters found in the GUI Reference Settings window. Do you have a script example showing this process? Thank you.

Python and Java API / Re-opening project with chunk
« on: June 03, 2022, 06:34:48 PM »
Hi. My workflow is the following:
- python script #1: create project, create chunk, add photos, photo matching and save
- open the project in the GUI and manually add GCP points and save
- python script #2: re-open the project and build the dense cloud
How do I re-open the project with the chunk already created?

Python and Java API / Assign pixel_size and focal_length to imported photos
« on: February 25, 2022, 05:44:15 PM »
Hi. I need to build a point cloud using 5 simultaneous sets of aerial photos (1 nadir view and 4 oblique views) with Python.
I'm stuck at the camera calibration step as I can't manage to assign the pixel_size and focal_length to the imported photos.
Below is the part of the script that should do it but when I run it and open the project in the GUI, the pixel_size and focal_length are blank. What is missing?

Code: [Select]
import Metashape
import os

data = "D:\Data"
project = Metashape.Document(), "project.psx"))
chunk = project.addChunk() = Metashape.CoordinateSystem("EPSG::32616")
views = ["nadir", "oblique1", "oblique2", "oblique3", "oblique4"]
sens = dict()
for view in views:
    sens[view] = chunk.addSensor()
    sens[view].label = view
    sens[view].pixel_size = Metashape.Vector([0.00520, 0.00520])
    if "oblique" in view:
        sens[view].focal_length = 123.0
        sens[view].focal_length = 82.0
photos = [os.path.join(data, f) for f in os.listdir(data) if f.endswith(".tif")]
for camera in chunk.cameras:
    for view in views:
        if view in camera.label:
            camera.sensor = sens[view]
