Bug Reports / Crashing on Mac Pro (2013)
« on: May 29, 2021, 03:50:51 AM »
I've been using Metashape for months without any problems.  Up until today I had always been generating my Meshes from the Dense Point cloud.  However, today I decided to try doing it from the Depth Map and using Ultra High quality.  4 out of 5 attempts have resulted in Metashape causing my Mac Pro (2013) to freeze and eventually reboot.  I'm not using a very large data set - everything I've tried has been between 60 and 100 photos.

Since the problem is happening during the Build Depth Map phase, I don't think it has anything to do with building the mesh.  I think it must have something to do with using the Ultra High quality setting.

When the computer reboots it shows me a crash log which usually looks about the same.  I have attached one of them.

General / Optimize Camera Alignment question
« on: May 28, 2021, 10:11:13 PM »
In the Instruction Manual in the Batch chapter it shows "Optimize Alignment" being done after Build Dense Cloud, but this doesn't make sense to me unless I'm missing something.  Shouldn't Optimize Alignment be done immediately after Align Photos and before anything else?

My understanding it the flow should be Align -> Optimize -> Build Dense -> Build Mesh -> Texture -> Export File


General / Key point limit per Mpx
« on: May 28, 2021, 03:39:29 PM »
When I setup a Batch and edit the Align parameters I see an option called "Key point limi per Mpx" which I do not see in the normal Align dialog.  I cannot find any documentation or discussion about what this does.

I assume Mpx means image megapixel?  So, if I have a 20 megapixel image does that mean it'll limit key points to 20,000 and override the 40,000 key point limit I have set? 

General / Alignment preselection speed vs. accuracy
« on: May 28, 2021, 03:12:49 PM »
I'm trying to better understand the consequences of using Generic Preselection and Reference Preselection when aligning photos.  I know that enabling Generic Preselection speeds things up significantly, but will that affect the geometric accuracy of my final 3D mesh in any way?  For the work I'm doing, the accuracy of the final model is critical, so I don't mind having to spend a few extra minutes aligning the cameras, but I'm not clear if it actually matters in the end after the dense point cloud and resulting mesh are generated.



Feature Requests / Auto Image Quality Removal in Batch
« on: May 28, 2021, 02:38:30 PM »
It would be really helpful if the Image Quality feature could be added to a Batch, and if it could be setup to automatically remove any photos below a set quality factor.  Currently, I have to do this manually and then run the rest of my Batch when I'm done, but if it could be automated it would save a lot of time.


Feature Requests / HEIC image format
« on: May 20, 2021, 02:34:31 PM »
I really, really, really wish Metashape would support the HEIC image format.  We are making 3D scans from photos that customers submit to us, and many of them are using newer iPhones and sending us HEIC files.  It's a pain to have to convert them every time.  It would be great if Metashape could read them, even if only on the Mac since it's just 1 line of code to do it.

Feature Requests / Sequential Batch Operations
« on: March 31, 2021, 08:45:57 PM »
I love Metashape, and I only have 1 issue with it:  the batch operations go in parallel instead of sequentially.  Right now if I have, say, 5 Chunks that I want to batch I have to wait for all of them to be completed at the same time instead of having the first one complete while it continues working on the next one.  This prevents me from doing any work until *all* of them have completed.

If Metashape's Batch function had an option to complete one Chunk at time it would help me tremendously!  Right now I have to wait hours for all of the Chunks to complete, but if it went one-by-one I could be working on one project while Metashape continues to work in the background.



Feature Requests / Keyboard shortcuts
« on: March 23, 2021, 04:15:16 PM »
I really wish there were some keyboard shortcuts for the operations that I use most often:

1.  Rename Chunk
2.  Add Files / Folder
3.  Batch Process


General / Metashape on Apple Silicon
« on: February 17, 2021, 07:26:59 PM »
I bought Metashape last week, and I'm blown away at how good it is.  I had been dabbling with Photogrammetry for many years using other resources, but Metashape has been a game changer for me.

I'm currently running it on my old Mac Pro and it is reasonably quick (once I enabled the GPU acceleration).  I'm wondering if there will be an update for Apple Silicon soon as I'm looking to upgrade my Mac sometime later this year.  I'm hoping it'll be even faster on that!
