Python and Java API / Solving an Error with detection object script in agisoft

« on: February 13, 2023, 09:54:49 PM »

I am trying to follow this tutorial for detecting objects: https://agisoft.freshdesk.com/support/solutions/articles/31000162552-automatic-detection-of-objects-on-orthomosaic  , the training and detection are going very well but when I try to make a detection with the created model it gives me the following error in the console:

2023-02-13 09:17:09 Traceback (most recent call last):

Anyone know how to solve this error?

Python and Java API / problem with importPoints()

« on: November 24, 2022, 10:12:05 PM »

When using the importPoints method in a script to import multiple .LAZ files it imports the files one by one but always replacing the previous one leaving only the last one.

How can I avoid this and then combine all the files?
 this is my code...

Code: [Select]


import Metashape

from os import listdir
print('starting...')

path = 'the path'

files = listdir(path)

for i in files:
    print(i,end="\r")

    if i[-4:len(i)] == '.laz':

        print('importando... {}'.format(i), end="\r")
        path2 = path+'/'+i
        Metashape.app.document.chunk.importPoints(path2)
