I had tried Merge Chunks first, but this failed - as described in my first message.

I don't know why it should do image matching. Each of the two projects have a good mesh. I was hoping that the meshes would just join up, with some way of averaging them where they overlapped.

I expect to complete the orthophoto production on my PC within about 36 hours. Once I've checked those on Monday (NZ time), I will consider cancelling the Cloud processing, which may still be running.

Hi Alexey,

I'm running the align chunks now. It is taking a very long time.
Meanwhile I'm creating orthophotos on each separate chunk in case I don't end up with one good combined project.

General / Agisoft Cloud failure
« on: December 10, 2020, 04:19:26 AM »
So I was merging two chunks on Agisoft Cloud and this is the email I received.

processing failed :(
We are sorry to tell you that an error occurred while processing your project.
Please try again!
https://cloud.agisoft.com

No hints as to what went wrong!
Unfortunately there is no log file accessible that I could see.

When I sync it back to my PC, I see this in the log - perhaps helpful?
Error: Empty pairs list

Hold that thought:
Looks like I missed a step. Have to align chunks before I merge them. Perhaps a warning would have helped?

General / glDrawElements - out of memory
« on: December 08, 2020, 03:58:47 AM »
I created a high quality mesh on Agisoft Cloud.
When I open my project, the files download successfully, but then I get a large number of out of memory errors, such as
renderer_qgl.cpp line 616: glDrawElements(encodePrimitiveType(type), (GLsizei) countElements(type, chunk), encodeFormat(iformat), (GLvoid *) ((char *) indices + offset)) failed: Out of memory

Is this just a display/rendering error/limitation?
Can I still proceed to use the files, or have I lost data?


Thanks
Ross

General / Merging two .psx files
« on: December 07, 2020, 03:49:16 AM »
I see that I can use FILE > APPEND to merge two .psx files.

Can that be done at almost any stage? I'm going to create the two meshes first, as this is memory intensive. Then merge the models. Then create orthophoto tiles after that.

My reason is so there are no image glitches in the overlap area of the two models.
Good idea? No problems likely?

Thanks.

Thanks Alexey.
I have got one third of it processing at the moment. I will consider combining the other two-thirds for the next chunk later tomorrow, and will email my request then.

General / Cloud processing limits
« on: November 29, 2020, 03:56:59 AM »
I have a project with about 116GB of aerial photos. After trying to upload to the Cloud, I discovered there is a 50GB limit. Should I divide them up into about three slightly overlapping areas? I'm only needing orthophoto tiles as final output. Would I just save the mesh from each of the three runs and then continue the process from my underpowered old PC?

General / Minimum percent overlap
« on: September 08, 2020, 01:21:08 AM »
I understand that a 60% or higher overlap is required for aerial photos in a run.
If there are several parallel runs, what is the minimum percent overlap with the adjacent runs?
These will all need to align in Metashape and be processed in one chunk.

Thanks.

I haven't noticed any problem with slightly different focal lengths. A mix of 24, 25, 26mm focal lengths has worked fine for me. It may depend how detailed and precise the result needs to be.

I have used this free software. https://www.microsoft.com/en-us/research/product/computational-photography-applications/image-composite-editor/
It does not use any EXIF or GPS related data, so you won't get an orthographically correct image.

Bug Reports / Photo path not saved correctly
« on: December 30, 2019, 05:51:12 AM »
Something to be aware of. Not sure but this may be a recent bug with Version 1.5.5 build 9097 (64 bit).

I had my photos masked and aligned. I saved the project. When I imported my GCPs, all the photos disappeared.
I am using the Windows 'File History' option, so was able to get a good previous frame.zip file restored. I could then see what happened.
The project was saved on a network PC (UNC path). My photo folder is on my local PC. Metashape had saved the path as if that folder was local.
Search and replaced the photo paths with the UNC folder name. Project now opens correctly.

General / Re: Manual alignment - how?
« on: October 31, 2019, 04:50:49 AM »
Have tried that with 3,4,5, & 6 points selected on one aligned photo and the next (non-aligned) photo. No luck. Perhaps it is because this pair only has about a 40% overlap. I will resort to some single-photo orthorectifications (in another program) to finish this job.

General / Manual alignment - how?
« on: October 29, 2019, 05:04:12 AM »
Could I have a step-by step procedure for manual alignment please?

Most of my (aerial) photos have aligned.
I have placed 3 points on one unaligned photo. Then placed the same points on the next unaligned photo. I select these two photos, reset and align selected photos. Nothing shows in the aligned column. What else do I need to do?

I have used 'Process Lasso Pro' https://bitsum.com/?inproduct to control resource usage of processes. I see there is an option to control 'I/O priority' so perhaps setting that to 'Very Low' would work.
