General / What governs possible projections to be exported?

« Last post by 3DWinter on Today at 09:05:22 AM »

Hello,
I cannot understand why I cannot export the file to projected UTM. I can export to Lat Long, Projected Albers, but not UTM. For some reason with a different data set, I can export to UTM. Both data sets were processed with lat-long coordinates.

General / 4DMapper Upload Broken?

« Last post by SP74 on Today at 07:16:09 AM »

Hi,

I have generated an number of 3D Tiled models with Metashape (1.5.0 build 7492), and have attempted to upload them to 4DMapper.  The upload appear to be successful, and the relevant project and 3D Tiles layer was created and no errors were reported.  However the model does not load, there is just a black globe.    I have provided a link to the dataset.

https://app.4dmapper.com/user/share/35bec1539cfb5b6f933a131a1f303c2de7107f6bb347f7ce

I also tried to upload a model from Metashape that I had previously uploaded using Photoscan and I got the same failure to load.  It looks like something has changed/broken with Metashapes 4DMapper upload.

Cheers,

Stu.

General / Split in Chunks script Merge Back option leaves only the re aligned cameras?

« Last post by MitchellT on Today at 03:06:14 AM »

I have a chunk that has 529 Cameras, 414742 tie points, and dense cloud of 128,115,016 points than runs out of memory (32 meg) trying to build the mesh. I tried using the Split in Chunks script, without selecting merge back and exported the 9  chunks of mesh into Zbrush and assembled them there.

As it ran it the first time,  I noticed the seductive merge back button, and tried it several times. It builds the meshes, depth maps and then only returns a merged chunk with with just 529 aligned cameras.

Bug, user error?  (I tried rebuilding dense cloud, auto save and of course build mesh with all the same result)

I will send the log file to support.

General / Generate Ortho image very slow in Metashape

« Last post by Mohammed on Today at 12:41:43 AM »

Hi Agisoft team,

I have a project contain 17500 images photographed in 2014 underwater when i tried to generate ortho image the bar give me 21 hour and increased every 1h h, so i back to my lovely old version V1.1.6 and it only took 6 hour to finish it.

The second issue some times i use V1.1.6 to create Orthophotos underwater because it treat and blend underwater colors (especially high light areas) in a very good way , now after i align photos used Metashap i saved the file in PSZ V1.0 format then build the ortho in the old version the result of the final ortho photo looks like stretched all the images and it looks so bad, i believe its a bug could you please check it?.

Thanks
Mohammed

General / Re: WGS84 UTM36S with EGM2008

Hello Owen!

Have you tried to use Convert option after processing the alignment in WGS84 coordinates and then select the custom coordinate system that can be created by editing WGS 84 / UTM zone 36S system by adding EGM2008 in the Vertical CS field.

Maybe the following instruction would be helpful to you for the custom coordinate system creation:

General / Aligning with Point Based Method

« Last post by eytanmannko on February 21, 2019, 09:40:11 PM »

Hello,

I'm trying to align multiple chunks using the align chunk command, using Point Based alignment.
I've noticed that it will align only two-chunks at a time. Not all chunks.

If I use camera based alignment, I can do multiple chunks at a time...

Anyone knows why is that?

Thanks

Thanks Alexey
I thought, just add 'Tasks.network_distribute = True'

General / Re: more CUDA ERROR - Error: CUDA_ERROR_UNKNOWN (999) at line 128

« Last post by Alexey Pasumansky on February 21, 2019, 08:24:25 PM »

Hello Andy,

It's quite difficult to investigate such issues, as they seem to be related to hardware configurations (from mechanical defect to power supply or over/under-clocking) or drivers. So far we were not able to reproduce anything similar on our test configurations, that include NVIDIA cards of different series.
