Solving an Error with detection object script in agisoft

[ro-teodoro]

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?

forget it, everything is cancelled. It takes the crs of the shapes in the project as a reference, it was only necessary to add the training shapes to use them in the detection. thanks all the same.

What did you to do resolve this?

Hello arpit.p,

Can you share the output from the Console pane related to the script run? (you can remove sensible folder paths, if necessary, before posting).

Thanks for the reply!
The following error I am getting while running detections from a saved model. Although detections run on some other projects without any issues.
I am using 1.7 version of detect_objects.py

[Alexey Pasumansky]

Hello arpit.p,

Please check, that coordinate system for shapes is defined, providing that shapes are present in the project.

If it should be the same as for the chunk or orthomosaic, try to define it manually before running the script:

Code: [Select]

Metashape.app.document.chunk.shapes.crs = Metashape.app.document.chunk.crs

Are there any shapes in the project?

[arpit.p]

Actually no. I think that was the issue.
Thanks for the reply.
I made a shape manually and then it works fine.
