For any following this. Yes - it was a mix up of professional and standard keys purchased at the same time.

I'm on a roll today.

Thanks as always for the help!

Hi Alexey,
It looks like it was the driver: I can make dense clouds now (slowly) on my newer laptop (with all updated drivers), but my antiquated research computer is having trouble updating the driver - throwing all sorts of weird errors. The executive summary here is that the problem is with the computer and not with metashape. I'll keep working at it, but the problem has at least been isolated now.

Thanks for all your help. You are a giant among men.

Hi Alexey,
I believe the drivers are now up to date, but I still got zero resolution on a small test project. The screenshots you asked for are posted below.

Thanks for your thoughts.

Hi Alexey,
Thank you for the suggestion. I am updating drivers right now and will advise as to whether this solution works. If not, I'll upload those  screenshots.

I appreciate the help,
Brian

General / Link for installing Photoscan (not Metashape)

Hi folks,
Is there anywhere I can download the last version of Photoscan before it switched to Metashape? The standard version of metashape has less functionality for the work I do but I mistakenly updated and would like to go back.

Thanks,
Brian

As a follow up. After the dense cloud fails, when I look at the photos with the "show depth map" button pressed, all the photos are black. I'm not sure how this would affect things but I saw the request for this information on another forum post about Zero Resolution.

Hi Cronos,
Thanks for the suggestion. As I understand, the depth maps are not created until after I try to create a dense cloud. Once the dense cloud completes (with zero resolution), I can go back and delete the depth maps, but there are no depth maps present the first time I try to build the dense cloud.

I do appreciate the suggestion. I made a video to show (with a very small sample set) what is happening...

https://appstate.zoom.us/rec/share/9WO3s-H1-8itvoHd1g9htd_LT5RkjFO-1XWWJbOsYH2u0V0s_KqyjYkngpvynKXo.g5C44IoyatpqYx5Q

This same thing happens with much larger image sets (55+ images) so I do not think it is related to not having enough projections.

Thanks,
Brian

Hi Chronos,
Thanks for the note. Are depth images different from depth maps? I have unselected "reuse depth maps" when making the dense cloud but still have the problem. Is there a way to ensure the depth images are deleted?

Thanks for your help,
Brian

General / Zero Resolution coming up on all models
« on: May 14, 2021, 03:26:35 PM »
Hi All,
I used Photoscan for years and recently updated to Metashape. As I started running new models, I've had issues with getting "Zero Resolution" when building my dense clouds.

I've double-checked my bounding box (common problem for this error) and run several models at different photo alignment resolutions, unlimited tie points, different dense cloud qualities, etc and each time I get zero resolution after processing for the dense cloud. Plenty of projections and reasonable errors (see image). This has been the problem on multiple models - all permutations of model-building options. It feels like something changed from photoscan to metashape and I am missing a step.

Any help would be greatly appreciated. Sample project file available but too large to post here.

Thanks,
Brian

Hi Alexy,
Thanks for the response! I will give it a go. Thanks :)

General / Mesh bridging
« on: May 01, 2018, 05:28:44 PM »
Hi All,
I am making a mesh of a plesiosaur scapula and my dense cloud looks solid (Image 1), but when I make the mesh (from the dense cloud, interpolation enabled, 200k faces), it bridges across an area where there should be a gap. (Image 2). I have manually cleared that area of points from the dense cloud and tried running the mesh with several parameters alteredand the bridge keeps forming. I can disable interpolation and get it to disappear, but it really hurts the quality of the rest of the mesh. Is there any way to still use interpolation and not get this bridging?

Thanks for the assistance!
Brian

Hi SAV,
I've been using CloudCompare for... well... comparing the clouds but I didn't realize it had this extensive functionality. It will do exactly what I need it to. Thanks for the response and links!

General / Setting Z in local coordinate system
« on: September 29, 2017, 08:16:41 PM »
Hi Folks,
I am creating DEM's of footprints pressed into volcanic ash. My question is...
Can I artificially set the z value of my model in the local coordinate system?

Essentially, I have several prints I am trying to show comparisons between and my current DEMs have arbitrary min and max values when I draw on contours.

I have already used the bounding box alignment script to get the print properly oriented, but I'd like all my DEM contours to show comparable values (say 0-2cm) instead of one print showing z values of 15-17cm and another -6to-8cm.

My thought was to place a marker at the low point and set the z value to 0, but to create a DEM, you need three points. All prints are scaled.

Thanks for the assist. I love this software!

Brian
