General / Re: I want to export baked normal map texture as 16 bit PNG.

« on: June 06, 2024, 11:27:25 AM »

Dear Amal,

Please try to use the following commands:
import Metashape
chunk = Metashape.app.document.chunk
image = chunk.model.textures[1].image()
image = image.convert("RGBA","U16")
image.save('//..../u16_dm2.png')

General / Re: Incremental images alignement not working

« on: April 26, 2024, 11:24:10 AM »

Dear djyoung,

During the incremental alignment, the chunk.transform changes, so you can observe a slight shift in the original tie point cloud. If you want to leave the first part unchanged, then as a workaround we can offer the following workflow:
- In one chunk, perform alignment for the data that you would like not to change.
- After that, duplicate it (select Duplicate... command from the Chunk context menu on the Workspace pane).
- Add the part you want to align to the duplicated chunk and perform the alignment.
- After that, using Python, you can apply the transformation matrix from the first chunk to the second. To do this, open the Console pane (select View > Console) and run the following command:
Metashape.app.document.chunks[1].transform.matrix = Metashape.app.document.chunks[0].transform.matrix

Feature Requests / Re: pointcloud intensity import and export

« on: March 14, 2024, 11:58:13 AM »

Dear Remco,

Metashape 2.x displays the Intensity for a point cloud. Since point clouds may have a very different range of intensity, the values for your point cloud may be too small, so it is displayed in black. In this case, for the convenience of display, we can suggest using the - Set Brightness tool (select Tools > Set Brightness).

But we want to note that if there are images in the project, then the tool will be applied to them as well. We will think about how to improve this tool so that it is convenient to adjust the values for display.

For now, we can offer the workflow described above. We hope it will suit you.

General / Re: 3D Pipe Modelling

« on: March 14, 2024, 11:49:33 AM »

Dear Sandy006,

The problem is related to the texture of the object. The object is quite glossy and reflects a lot of light. Therefore, unfortunately, you observe irregularities in the geometry.

If it is possible spread some talc powder (or anything similar) over it to change it from glittering to the dull surface. Also in some case we can offer use Smooth Mesh tool (select Tools > Mesh > Smooth Mesh). The Smooth tool allows you to make the model smoother and remove irregularities on the surface.

Dear Kalanka,

We apologize for the inconvenience. Thank you for the bug report.

We fixed the problem.  The changes will be included in the next version of Metashape.

General / Re: Import coordinates for laserscans

« on: January 24, 2024, 12:00:02 PM »

Dear Dieter,

1) Unfortunately, there is no such possibility now. But we can offer our script like workaround. You need to open a project with alignment (where you removed lock transform and the external orientation for laser scans was changed). After that, run the script. After running the script, there will be a dialog box where you need to select the source file with the laser scan. As a result, the script will shift the result of your alignment to this laser scan.

2) Yes, the key points of both types are optimized together.

3)We can suggest using the Measure Profile tool for horizontal surfaces (you can find information about this tool in our article -  https://agisoft.freshdesk.com/a/solutions/articles/31000170365) . You can also use markers (specify the markers on two clouds and check the error in the Reference pane). Unfortunately, other methods are not currently implemented in Metashape.

Dear Dieter,

Thank you for your test and your feedback.  Please clarify if we understood correctly that many matches were found between the images and the laser scans, but they were not aligned?

If yes, do you have the opportunity to send us your project and the images that you used in the project to analyze the problem on our side? Please send the data to support@agisoft.com.

General / Re: Export confidence as a texture map?

« on: December 29, 2023, 04:17:18 PM »

Dear J.K.,

Thank you for your feedback.

You can use the scripts from Github that you have linked to. The vertices of the model will be colored according to the parameters you need. And after that, you can start building a texture and simply use the desired model as the source data (a model with altitude coloring and a model with overlay coloring). This way you will create the texture you need. I've added texture building commands to the scripts.

You are welcome, have a nice day!

General / Re: Export confidence as a texture map?

« on: December 27, 2023, 01:59:23 PM »

Good afternoon,

We can suggest testing our script as a workaround (recommend testing the script on a small project). 

The script colors the vertices by confidence, and then bake texture. Also please note that the model is built from depth maps and with vertex colors.

Select Tools > Run script... and choose the script. After that select Scripts > Texture Model with Confidence.

Feature Requests / Re: Orthomosaic creation advanced cylindrical projection with axis

« on: October 25, 2023, 01:44:21 PM »

Dear noodlez,

We modified the script. Now a shape is taken from the layer with the name - base (or Base, or BASE).
Left-to-right shape parameter - it is necessary to remove the checkbox when the shape is drawn from right to left.
Use hard normals parameter - for sharp corners (for example, for buildings), for smooth curves it is necessary to disable (in your case it is better to disable).

Python and Java API / Re: Running Metashape within Docker using python wrapper finishes with segfault

« on: October 23, 2023, 12:44:08 PM »

Dear Beda,

Thank you for the information.

On the headless server we were able to reproduce the problem. We are investigating the problem.

But for now we can only offer the following workarounds:

1. Use:
metashape-pro/metashape -platform offscreen -r general_workflow.py data output
 
2. Or check the success of the script execution through a self-written exif code. For example, save a text file at the end of the script "finished.txt " with the text "ok". And at the beginning of the script, delete it if there is one.

Hello,

We have published a pre-release version of Metashape 2.1: https://www.agisoft.com/forum/index.php?topic=15894.0

There is a minor improvement in mesh generation algorithm that reduces banding in some cases.

Bug Reports / Re: 2.0.2 Standard: Displacement maps not exporting

« on: July 27, 2023, 12:39:06 PM »

Dear taran,

You can check the displacement map in the UV Mapping dialog window (select Tools > Mesh > View Mesh UV ), the texture is actually not completely black.

Displacement map records offsets in the scale of the model coordinates, if the model coordinates are small, then some programs can display Displacement map almost black (or almost white if the coordinates are large). This is done so that users have the opportunity to use real offsets, and not selected "by eye".

We can offer you to export the texture in *.tiff format (since *.jpg doesn't support 32-bit floating point) and use this texture file if necessary in a third-party texture editing program.
