Python and Java API / Manipulate photo exif data with python
« on: March 06, 2024, 03:21:36 PM »
Hello Alexey and everybody else,

I'd like to manipulate exif data of my photo set. Is this possible via python script?

I'm able to read data in a for loop. But how can I wrtie new data to the .jpg file?

If I do it like this, the data is overwritten in Metashape. But the original file doesn't change...
Code: [Select]
cameras[0].photo.meta["Exif/Make"]="test"

General / FOV in model view & distance to object
« on: August 23, 2023, 10:24:05 AM »
Hello Alexey!

Hope you're doing well!

Would you please explain how  the perspective "FOV" in the model view is calculated?
I'm trying to suggest the distance from a scanned object in a photograph...

For example:
  • if you have a face scan...
  • FOV 70: you can see the ears from the front
  • FOV 30 to 0 : you can't see them

It's the same then stepping back and forth - changing the distance to the object. Hopefully you can help me out!

THANK YOU VERY MUCH!

Hello Alexey,

hopefully it will be a good new year for you!

Can you please tell me the currently best way to fully clear an alignment when duplicating a chunk? Still having problems some times when doing this.
Is it necessary to remove tiepoints, keypoints... or should "tranform=none" do the job?

Thank you very much!

Feature Requests / Re: Edit size of 'Show Cameras' rectangles

Hello Alexey!

Is there anything new to say to my question?
Thank you!

Hello everybody!

Is there a way to set/change the default size of the camera rectangle?
In my case they are always too big.

It would be best to have
  • an option in GUI
  • or tweak
  • or python function
...maybe in the next version?  ;)

By the way ... is there a python code to disable "show cameras"?

Thank you!  :)

Hello Alexey,

for a code that
  • duplicates a chunk for
  • testing several match and
  • alignment parameters
I need your help.

I'm duplicating a chunk to use my photos and masks again in some other chunks to test different parameters. But  I recognized, that the alignment results of my code are worse than using the same parameters in a new chunk (or via GUI), where I load the photos and masks manually.
So what am I doing wrong?

To make it short:   
Code: [Select]
chunk = chunk.copy(keypoints=False)
for camera in chunk.cameras:
                camera.transform = None
chunk.point_cloud.removeKeypoints()
chunk.point_cloud = None
chunk.remove(chunk.markers)
Then I match and align photos (reset matches = True).


Thank you!!!  :)

Dear Alexey,

can you please give me an advice how to solve the task?
How can I "zoom" automatically, so that all the mesh faces are shown?

Thank you!

Python and Java API / Show a picture in PySide2 Qt Gui
« on: August 26, 2021, 07:36:16 AM »
Hello everybody,

can someone please tell me how to show a small picture in a GUI?
I made some GUIs with PySide2 but I don't know how to load a fixed picture to them.

It must have to do with QPixmap ?!

Code: [Select]
from PySide2 import QtCore, QtGui, QtWidgets

class ref_korr_gui(QtWidgets.QDialog):

    def __init__ (self, parent):
        QtWidgets.QDialog.__init__(self, parent)
        doc = Metashape.app.document
        chunk = doc.chunk   
        self.setWindowTitle("Ref.-Korr.")
               
        image_path = "D:\Dropbox\Showreel\16 Markerplatten\Zusatzsoftware\Korrektur.jpg"

        picture = QtGui.QPixmap(image_path)
        self.label = QtWidgets.QLabel()
        self.label.setPixmap(picture)
        self.label.setGeometry(QtCore.QRect(10, 40, picture.width(), picture.height()))
        ...
        layout = QtWidgets.QGridLayout()
        layout.addWidget(self.label,           11,1)
        self.setLayout(layout)
        self.exec()

If I print(picture.width()) it is "0" ... But why?

Yes, that's what I try.
I hope to find a way to find a perfect fit for the pane automatically.

Thank you very much! Works perfectly for me!  ;D

The last challenge is to "zoom" in/out so that the model fits the size of the model pane ("mouse wheel function") (fov=0)

Do you have any idea how solve this?   
I'm searching for a way to find out it a point on my mesh is visible in the model pane or not.

Thanks again

Python and Java API / Metashape.Viepoint not writeable
« on: July 25, 2021, 03:36:29 PM »
Hello Alexey!

After rotating and scaling my model I calculate the middle of my model (vector "c") because I want to set the viewpoint there.
But the console tells me it is not writeable:

Metashape.app.model_view.viewpoint.center = c
2021-07-25 14:29:55 AttributeError: attribute 'center' of 'Metashape.Viewpoint' objects is not writable
2021-07-25 14:29:55 Error: attribute 'center' of 'Metashape.Viewpoint' objects is not writable   


Can you please tell me how to change the viewpoint?
Thank you very much!
