Bug Reports / Re: exportMarkers fails

« on: December 19, 2023, 11:40:18 PM »

Thanks, Alexey. It would be helpful to have an export class argument like the other export* functions, for example Metashape.MarkersFormatXML. I could not tell from the API what are the accepted formats.

Bug Reports / GUI cannot export current frame

Exporting a model from the current frame in the GUI loops over all frames instead. Exporting the point cloud works properly.

Python and Java API / Re: Availability of Tweaks in API?

Thanks, Alexey, this is great! So these are arguments that aren't detailed in the API? Is there a list of them elsewhere?

Python and Java API / Availability of Tweaks in API?

« on: November 30, 2023, 11:53:08 PM »

Are the advanced preferences Tweaks in the GUI also available through the API?

For example,

Code: [Select]

BuildModel/ooc_surface_blow_up
as detailed here.

Also, what seems to have previously been the Tweak for setting the ratio of valid tie points,

Code: [Select]

main/depth_point_threshold

Bug Reports / Re: Ms.Image.fromstring returns error

« on: November 20, 2023, 08:23:47 PM »

Thank you, Alexey.

Installed from whl in a custom conda environment with python 3.10.13. Ubuntu 23.04.

Possibly related to changes introduced in python 3.10.

I will try to downgrade my environment to <3.10.

EDIT: confirmed this operation works correctly on with python 3.7.12.

Bug Reports / Ms.Image.fromstring returns error

« on: November 20, 2023, 05:12:04 AM »

I have a numpy array I would like to import to Ms.Image. This code block has worked fine previously, possibly before upgrading to 2.0.

Code: [Select]

# image.dtype is dtype('uint8')
# image.shape is (800, 1280)
Ms.Image.fromstring(image, image.shape[1], image.shape[0], ' ', datatype='U8')

However, the first line returns the error,

Code: [Select]

SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats
Problem exists in 2.0.2 and 2.0.3.

General / plotting only marker dots?

« on: November 12, 2023, 10:26:28 PM »

I would like to be able to plot markers without the flags or labels, which hide densely placed markers. Is it possible to suppress these elements?

Bug Reports / 2.0.2 build 16404 Export model frame saves all frames

« on: August 06, 2023, 04:47:32 PM »

Expected behavior: Exporting model current frame will save the current frame.

Observed behavior: Exporting model current frame iterates through all frames in the project while saving and overwriting the same target file.

Python and Java API / license key for 1.8.x to 2.0.x upgrade?

« on: June 23, 2023, 05:59:25 PM »

Does a license for the previous version of Metashape pro upgrade to version 2, or is a new license required?

Python and Java API / Re: chunk.detectMarkers fails to find

« on: June 06, 2023, 12:12:47 AM »

Thanks Alexey, when I do this with the API I simply get an empty array in chunk.markers:.

> chunk.detectMarkers(frames=[chunk.frames[0].key])
DetectMarkers: marker type = Circular 12 bit, tolerance = 50

camera0: 2 targets
camera1: 0 targets
camera2: 2 targets
camera3: 2 targets
camera4: 3 targets
camera5: 3 targets

chunk.markers
Out[11]: []:

Thanks!

Unfortunately, chunk.markers still turns up empty.

Python and Java API / Re: chunk.detectMarkers fails to find

« on: June 05, 2023, 04:37:51 AM »

The error was a result of an interaction between chunk.addFrames() and removing frames. As a result, frame 0 of the chunk did not have key 0, and chunk.detectMarkers expects the key, not the frame number (which is not clear in the function help).

Python and Java API / chunk.detectMarkers fails to find

« on: June 05, 2023, 04:22:18 AM »

I am attempting to replicate the marker detection behavior of the GUI. In the GUI, all 12 bit markers are detected.

chunk.detectMarkers() detects all markers.

chunk.detectMarkers(frames=0) [or any other frame] returns nothing.

This is performed on the same doc. What does the GUI operation do that the (python) API does not?

General / u,v marker locations to 3D coordinates

« on: April 20, 2023, 02:37:18 AM »

Given a set u,v of markers in some number of calibrated frame cameras, can we rapidly return the 3D coordinates? I have used Metashape for calibrating, but I want to track marker motions (e.g., motion capture) independently of any constructed surface mesh.
