General / Script Import Points - georferenced [R]

« on: February 05, 2021, 12:38:24 PM »

Hi guys,

i have the following problem:

I import via Python script a (unstructured) E57 point cloud.
works fine, however the [R] Tag is not assigned and therefore the data gets messe up when reexport in Potree file.

when i import manually the data gets assigned with the [R] georeference tag.

console says both imports are the same commands.

Does anyone know how to import via script and get the data georeferenced?

Code: [Select]

chunk.importPoints(filepath,crs=chunk.crs,format=Metashape.PointsFormat.PointsFormatE57,calculate_normals=False)
chunk.exportPoints(outputpath,source_data=Metashape.DataSource.DenseCloudData,clip_to_boundary=False, binary=True, save_normals=False,save_colors=True, save_classes=False, save_confidence=False, raster_transform=Metashape.RasterTransformType.RasterTransformNone, colors_rgb_8bit=False, comment='', save_comment=False, format=Metashape.PointsFormat.PointsFormatPotree,crs=chunk.crs)

Hello,

i tried the new import laserscan function by importing a E57 file containing 54 Laserscans, exportet from Leica Register 360 (RTC360 data)

I have a problem when finishing the import:

Warning: disabled 54/54 reference records with zero GPS coordinates

The registration is lost.

General / Depth map generation performance

« on: December 15, 2020, 09:51:29 AM »

Hello,

i'm struggling with the depth map generation performance (v 1.6.5),
currently processing a 10k x 20mp corridor mission, splitted into several chunk.
The cpu workload is around 25% I7 8700K and the GPU Quadro RTX 4000 is around 5%, both with peaks up to higher percentages but only 1/10 of processing time.

why is the depth map generation so slow? i feel like it was faster in previous versions. (very high, mild filtering, no tweaks)

General / Long Aerial survey with Gaps

« on: December 05, 2020, 11:15:51 AM »

So quick question about recommondation from the Agisoft Team,

I have a large aerial survey (40km) with 2-3 gaps inbetween where flying was restricted.

Should i align all at once (which is less effort, no splitting etc)
or can i get same results when aligning all at once, even though they are NOT connected.

Thank you in advance

General / Potree Export Missing Points

« on: December 02, 2020, 10:05:27 AM »

Hello, any help appreciated:

I'm using the current Agisoft Version 1.6.5

When I'm using the Potree Export Function not all Points are exported, the Output seems to be truncated at a lower Z Limit (Points below a given height are missing)

I tried to duplicate the point cloud, compact the point cloud, export classified, export unclassified, using oversized bounding box, reset bounding box etc.. always the same result. Using a subset of the pointcloud works so i guess theres nothing wrong with my HTML/JS:

I found out that the point number given in the compacted Agisoft Chunk and the exported in the cloud.js does not match:
923.506.005 (Agisoft)
867.068.521 (Potree export cloud.js)

any suggestions?

Thank you in advance for the support

General / Change Coordinate Systems without transformation

« on: November 11, 2020, 01:58:04 PM »

So after i processed the project i recognized that i had the EPSG Code wrong.

The projects coordinate system is consistent so it does not affect the output. I can simple asign a new coordinate system using QGIS ACAD etc..

However i would like to change / update the coordinate system of the generated DEM / Orthophoto within Agisoft without applying any coordinate transformation... Any ideas?

Export and reimport would do the trick but i would like to find another way.

Thanks in advance
