General / Re: Link for installing Photoscan (not Metashape)
« on: Today at 04:22:37 PM »
Hello Brian,

It might be that you own both Standard and Professional edition license keys, but have accidentally confused them. The license key for Professional edition of PhotoScan would fit also Metashape Professional.

As for the Standard edition of Metashape, I can't remember any features that have been removed from it with any recent major version updates.

Hello PROBERT1968,

In the version 1.7.3 (currently available as pre-release) there's a Detach Markers command in the shape context menu.

If the script gives you empty labels for some markers, they are likely related to the shapes.

Hello AndrejH,

Metashape is using 7-parameter Helmert transformation in geocentric domain.

Please refer to pages 108-109 of the following document:

Hello Leon,

As a post processing step you could overlay the high and low quality DEMs (latter put as a bottom layer) in order to cover the gaps.

Feature Requests / Re: LAND XML format
« on: May 13, 2021, 05:33:53 PM »
That is quite an old request, but in 1.7.3 version LandXML export format for mesh has been added. If anyone is still using this format, we would be glad to hear the feedback (note that for huge models, exported file will be also quite big).

Pre-release can be checked here:

Hello Leon,

Do you get smaller number of holes in the resulting point cloud or DEM, if you use lower quality depth maps for the reconstruction?

Hello DaveB,

It's suggested to disable "save alpha channel" option when exporting orthomosaic to Q-GIS.
Also you can switch to black color for background option that can be used for transparency in Q-GIS later.

Hello PROBERT1968,

You can run this script for bov10_34 and see, which unpinned markers are listed and which coordinates do they have.

Please also check, if you have any shapes with attached markers (enable View Shapes in Photo view mode) - maybe they are related to the blued flags that you observe.

General / Re: Import Laser Scans
« on: May 12, 2021, 06:12:29 PM »
Hello ugo,

The problem seems to be related to the indirect order definition used in the file, instead of row/column index provided for each point.

At the moment such data representation is not supported (most likely, the support will not be included to the 1.7.3 update), so the solution at this point is to re-process the original scans in the native scanner application (providing that there's an option to use direct point indexing) or to re-save/convert E57 files in some point cloud utility that will add the direct indexing.

Hello Maciek,

Via Tools Menu -> Camera Calibration dialog -> Fixed parameters dialog you can select which calibration coefficients shouldn't be adjusted, so if their initial value is "zero", they will not be adjusted, if fixed.

Hello PollyT,

If the coordinate information and scale bar input is correct in the Reference pane, please press Update button on the Reference pane toolbar to apply this information. Then DEM should be re-built.

You may also need to consider building mesh using Arbitrary mode from the depth maps, as it seems you have generated it in Height Field mode and have quite a lot of unexpected "spikes" on the model.

General / Re: Metashape crashing intermittently during saves

Hello jrp,

Thank you for letting us know, we'll see, if anything can be done on our side on this matter.

Hello PROBERT1968,

If you execute the following code while at least one camera is selected, it will print out the console the information about the markers which have projections on the selected images and their pinned/unpinned status:

Code: [Select]
import Metashape
chunk = Metashape.app.document.chunk
for camera in chunk.cameras:
if not camera.selected:
continue
for marker in chunk.markers:
if camera in marker.projections.keys():
coord = marker.projections[camera].coord
pinned = marker.projections[camera].pinned
valid = marker.projections[camera].valid
if pinned:
pinned = "pinned (green flag)"
else:
pinned = "unpinned (blue flag)"
if not valid:
valid = "blocked/"
else:
valid =""
output = "{:s}\t{:s}\t{:.3f}\t{:.3f}\t{:s}{:s}\n".format(camera.label, marker.label, coord.x, coord.y, valid, pinned)
print(output)
print("script finished")

Hello Amaury,

Can you please submit the crash report and add this thread number (#13369) to the comments field , so that we could identify it.

Please also specify, which glibc version is installed on your system?

Python and Java API / Re: Build Texture Without Cameras
« on: May 12, 2021, 05:03:28 PM »
Hello seikamoomoo,

If the polygonal model contains the vertex color information, then you should use the following lines to build the texture (including UV layout) from the vertex colors:

Code: [Select]
chunk.buildUV()
chunk.buildTexture(blending_mode = Metashape.BlendingMode.MosaicBlending, texture_size = 4096, texture_type = Metashape.Model.TextureType.DiffuseMap, source_model = chunk.model, transfer_texture = False)
