General / Error: Can't align cameras
« on: July 14, 2021, 06:13:01 AM »
Hi guys,
I have just installed version 1.73.12473 professional.  Also I have swapped to a new gpu, an rtx 3080ti.  I have tried running a few photo sets through, and each time, during image alignment, Metashape pops up with this error and no aligned cameras....  These datasets were processed in previous versions and before the gpu switch.

Anyone having the same issue from the new version or from a similar gpu?

I have attached the console report as well.  It looks as though everything is fine until it reaches the stage where it is trying to match points using the gpu and it comes up with 0.


Solved: I took a better look at the forums here and learned about the 0 limit not working when aligning photos, My tie points and key points were both set at 0, changing this to a high number fixed this

Hi Photoscan community,

I am hoping to get help in wrapping my head around a problem I am experiencing.
I was given truncated coords for my GCPs, I converted these into standard UTM to assist in pinning the GCPs within Photoscan.

After pinning the targets, instead of importing the truncated target coords back in, I optimized the sparse point surface based on my converted UTM coords...  This is where I am lost.  The optimized surface based off the UTM coords has an average error of 2cm.  When I import the truncated coords back in, the error sits around 30cm...

I screwed up further by going ahead and building the dense point surface before importing the truncated coords and finding out about the error... Worse yet, I have spent a day filtering this Dense point surface that took 2 days to process.

I am assuming that I will need to go back and optimize the sparse point surface based on the truncated coords to correct this then rebuild the dense point surface and then start filtering again.

My question to the community is,  Where does this error come from?  when going back and forth between truncated and non-truncated coords, isn't the model just shifting in x/y space?  the elevations are unchanged between the two coord systems...  Photoscan is telling me that the error is in the elevation values however...  Why is error being introduced in elevation from a simple x/y shift?

If anyone can help me wrap my head around this it would be greatly appreciated.


General / Help with License
« on: February 10, 2017, 04:06:38 AM »
Hi guys, 

I just installed the latest version and typed in my key... However it is saying "wrong host for license"

This is the pro x64 version 1.3 build 3772

I had a previous build of version 1.3 installed for some time but downgraded to an older version due to a bug.  I am thinking this is where my issue is coming from because I did not deactivate the 1.3 license before installing 1.2 again.  I think Photoscan has my license tied to my machine for the previous 1.3 build and I dont know how to deactivate it now to re-activate for the latest build...  Any help would be much appreciated.


Bug Reports / Photoscan changes the Projection when importing GCPs
« on: February 02, 2017, 10:32:16 PM »
HI guys,

I am trying to process a small dataset in NAD83 UTM zone 10N.  Normally this works just fine, however for some reason when I try to import my GCPs, Photoscan is changing the overall projection to NAD83 UTM zone 11N.

I have never experienced this issue before.  I am using version 1.3.0 build 3620.

Initially I though I had just chosen the wrong projection by mistake, unfortunately I have gone through this three times now.

Feature Requests / VR Viewer
« on: December 04, 2016, 02:39:40 PM »
Hi guys,

I have started to import photoscan models into Destinations VR viewer this past week.  It would be great if Photoscan provided a viewer for this type of thing.

It is a fantastic way of showing off aerial surveys.

General / Help with GCP tie-ins after initial survey
« on: August 05, 2016, 05:29:20 PM »
Hello again everyone,

I am working on a survey where some of the GCPs placed on-site had moved just before photos were taken...  I have isolated these erroneous markers and processed the data to not include these GCPs.

However, the resulting DSM is flawed in the areas missing the GCPs as expected and I have been trying to correct this without reflying the site. 

A surveyor has collected a series of points on-site now in areas where no changes to topology have occurred. I want to use these to drive the elevations of the incorrect regions.  My thinking was that I could simply drop these phantom GCP points into my data, go along and tag them to their corresponding photos where photoscan estimates that they should be, and optimize the points. 

It looked as though it was working well, too well in fact, and it is now clear that it did not work at all.  After optimization, Photoscan tells me that there is error in the new points between .2 and 3cm...  but after building a new dense cloud, these points are still stranded in the air and not actually helping to drive the new elevations....  The Resulting DSM is exactly the same as the DSM without these points added.

Any ideas from the gurus out there?


General / Help creating a .prj file for Local Mine Grid
« on: July 28, 2016, 01:24:18 AM »
Hi Guys,

I am having a hard time trying to wrap my head around building this .prj file and getting it to work inside PS Pro.

I have a set of images from my client that I assume they screen capped from MineSite.  I have put a word doc together with all the info contained in the images to make this easier.   I am hoping that someone can help me use this information to put together  a working .prj file that photoscan can read.

Much thanks,



I am using Global Mapper to help me sort this out.  It appears however that the .prj files GM creates are not directly compatible with PS.  I have attached 2 UTM NAD83 10N .prj files, one from PS and one from GM.  It looks like the authority tags are the only difference.   What am I missing here, do I need to find Authority tags to let me create a .prj file for PS?

General / Will Photoscan work well with a ram disk?
« on: November 10, 2015, 04:34:01 AM »
Hi guys,

I am building a new PC to pair with my current xeon rig and have a question regarding ram.

I want to go with an i7 for this build and the max ram it supports is 64gb.  Motherboard supports up to 128gb though.

If I build with 128gb of ram, will Photoscan be able to utilize the additional 64gb if I assign it as a ram disk?  Has anyone tried doing something like this before?

I may try this setup and if it does not work out I can swap the i7 for a quick single xeon to get all the ram working.   

Build looks like this right now:

Intel Core i7 – 5820K Processor

Intel Liquid Cooling

MSI X99A Gaming 7 Motherboard

Thermaltake Core X9 ATX Desktop Case

128GB RAM (Crucial 16GB x 8)

 1200W PSU

Intel 480GB 2.5” SSD

Western Digital 4TB Red HDD

MSI R9 390 Gaming 8GB DDR5 GPU

General / Help Creating a custom .prj file
« on: April 24, 2015, 07:41:04 PM »
Hello everyone,

I come to you today for help with this custom projection I am trying to work out.

I am not the sharpest with these things and I could really use some help.

So far whenever I try altering the NAD83 UTM 10 prj file, I get an error in photoscan that the transformation is not supported.

My clients supply me with GCPs in their custom grid format as per the attached PDF.  I would like to be able to use these coordinates straight inside photoscan and directly output my data in custom projection that my clients want.

I also use Global Mapper, if anyone knows a good workflow for performing these conversions.

Thanks in advance

First time I ever recieved this message while trying to optimize to high accuracy gcps.  Is this something new in this release?

Agisoft Viewer / Agisoft Viewer Camera Track?
« on: February 04, 2015, 08:52:30 AM »
Hi guys,
I see the option to include a camera track in the viewer. is there a how to or any info about this feature?
It would be great to record some kind of flythroughs for larger models.


Bug Reports / Photoscan 1.1 Release 1982 Activation Issue
« on: October 20, 2014, 11:48:00 PM »
Hi guys,

when trying to activate build 1982, it asks for a valid license.  However, once I input my license, the "ok" button is still greyed out and will not let me activate. 

Is this happening to anyone else?


(Edit)   I downloaded the standard version by mistake...  Feeling kind of silly:-
