General / Link for installing Photoscan (not Metashape)
« on: May 15, 2021, 01:27:22 AM »
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.


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.


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!

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!


General / Minimum image coverage options
« on: September 19, 2017, 10:29:12 PM »
Hello All,
I am currently trying to reconstruct imagery of Athabasca glacier from a set of historical air photos. Unfortunately there are only seven images and their overlap is certainly sub-optimal. While I know the resolution of the render will be limited, I am still working to make the best model possible. I have gotten the images to align by adjusting the keypoints to 60,000 and the tie points down to 2,000. The problem is that I have two spots that appear to not have enough coverage (See attached image). Interestingly, the two wedges that are missing in the dense cloud are in areas that have three projections and are some of the better imaged parts of the data set. The geometry of the missing wedges suggests to me there is something systemic to my process that is removing data from those places as opposed to there not being coverage.

Any ideas on how to get those wedges of missing data to render?


General / Manually Placed Markers Auto-placement?
« on: August 30, 2017, 04:48:16 PM »
Hi All,
When I manually place markers for scaling my models using non-coded devices like rulers, I noticed that now Agisoft automatically places blue flag markers on all my pictures. I can manually go through and delete them, but is there a way to not have Agisoft automatically place the blue flags or to batch remove them from images not showing the ruler?

Thanks for the help!
