Python and Java API / Question about TriangulateTiePoints

« on: November 29, 2023, 10:10:03 PM »

Can I get an explanation of what TriangulateTiePoints does and where is it in the GUI?, I know it adds tie points.
In a certain project it added 200k of noise tie points

General / building Orthomosaic from point cloud

« on: November 06, 2023, 06:09:11 PM »

As Metashape 2.0.1 supports point cloud based orthomosaic generation, I am failing to build one, here is what I am doing:
1- import point cloud
2- build DEM
3- I try to build orthomosaic but the button is blocked

General / mixed data of frame and fisheye

« on: June 08, 2023, 03:05:51 PM »

I have a Dataset of both frame and fisheye images, What is the correct way of processing this Data ?
I currently create 2 calibration groups, one frame and the second fisheye, no problem with alignment, but when I do optimize cameras I get bad accuracy

Python and Java API / Vertical Datum support

« on: April 09, 2023, 07:05:51 PM »

Hello,

I am familiar with adding the geoid model to the geoid folder steps described in https://agisoft.freshdesk.com/support/solutions/articles/31000148332-how-to-use-height-above-geoid-for-the-coordinate-system
However, I am currently working with the python standalone image 1.8.4 in a docker.

I am familiar with "addGeoid" function but I'd rather have the docker ready to run without activating the geoid model every time I run a new docker. is there a way to add more than one geoid model to the images at once in Dockerfile maybe?Please help.

Thanks in Advance!

General / Export Raster size in GB

« on: March 05, 2023, 05:04:05 PM »

When exporting a raster, is there a way to predict the size of the raster in the GB before exporting it?

I'm trying to decide whether to split the raster into tiles or to keep it in one file based on the size in GB. And I have big files, so I can't afford to export them and check the size and then decide.

Python and Java API / Re: Change region from BBOX to Polygon

« on: September 06, 2022, 05:14:19 PM »

Yes, that's what I do now.
But If the job has X shape then I'm wasting storage and time generating DEM in empty spaces (I'm using extrapolation - no images). I thought it would be better to create generate DEM only inside the boundary instead of BBOX.

General / Change region from BBOX to Polygon

« on: September 06, 2022, 02:30:50 PM »

Hi,

I'm trying to build DEM for a certain region, I drew a polygon around it created a border. However, when Building DEM it builds DEM for the whole BBOX.
Is there a way to build DEM only for the region inside the polygon??

Hi,

What is the best way to get the border points around my point cloud or DEM in XY plane, 
I need those points to create a polygon around the DEM

General / Rolling shutter

« on: July 21, 2022, 10:29:08 PM »

Metashape 1.8.4 allows regularized and full compensation.

I understand the difference between them, but I do not know how to choose between them,

1- Is Full always better than regularized ?
2- Is there a way (manually/automatically) to detect the need for compensation in images?

Python and Java API / Export Raster

« on: May 25, 2022, 08:28:39 AM »

using Metashape 1.8.3
When I use export raster and select tile_width and tile_height they only work if global_profile is False, does the global_profile overwrite the tile_width and tile_height to 256 ?
      

Code: [Select]

chunk.exportRaster(path=os.path.join(work_path,'OrthoTiles.ZIP'),source_data=Metashape.OrthomosaicData,format=Metashape.RasterFormatTMS,image_format=Metashape.ImageFormatPNG,max_zoom_level=23,min_zoom_level=0,global_profile=True,tile_width=512, tile_height=512)
