Bug Reports / Re: Agisoft Photoscan 1.3.1 crashes when dense cloud is building.

« on: May 29, 2017, 06:46:31 AM »

Just throwing in my two cents...

I was using a GeForce 560 and never had problems with Photoscan
I then installed a GeForce 1080ti and after that had problems with building the dense cloud. Right when it was filtering the depth maps the program would crash or Windows would get an error and the computer would reboot. I'm going to try reinstalling my old video card to see if that's the problem... Sucks if the 1080ti has compatibility issues with PhotoScan.

 Yes I have submitted report I believe. Seems like it crashes right when PhotoScan starts filtering depth maps. Here's the last few lines of the log...

 I have still been getting crashes. Mostly from building the dense cloud and sometimes even from aligning photos. I did a clean Windows install and tried again. Dense cloud is still crashing.

Does anyone know what I could do? I have updated Photoscan, drivers and now Windows.

 That's how I understood it too. I wasn't sure though. If I uncheck the video card then would Photoscan utilize it still??

I just tried it anyways while it was processing the dense cloud. I watched the console and it didn't use the GPU at all. Just CPU the whole time...

Not sure how thats supposed to be a viable solution.

There's some problem in CUDA i guess, so at the moment you can sidable the GPU Cuda from the preferences menu.

Ok thanks I'll check this out. What do you mean with "you can sidable"?

General / New Video Card = Photoscan Crashing?

« on: May 12, 2017, 02:43:45 AM »

 I recently bought a GIGABYTE AORUS GeForce GTX 1080 Ti Xtreme Edtion 11GB Video Card - 1721/1607 MHz.
Before I had a Geforce 570, so I was hoping it would help with larger amounts of pictures in Photoscan.

The problem is that Photoscan will unexpectedly crash in the middle of different processes. I started a new project and it crashed while generating the dense cloud. And then I opened an existing project that already had the dense cloud created, but Photoscan crashed when I was classifying the ground points.

In other software, such as Adobe Premiere, it seems to be working fine. So far I'm having too much trouble for the money I put into this video card.

Does anyone have any suggestions?? I did check in 'Preferences' and my video card is selected there.

 Each photo has fairly accurate co-ordinates in the meta-data. And the elevation difference is about 40-60 meters.

I have had this problem before with merging chunks. And I did figure it out. It was a simple solution but I haven't been able to replicate it.

General / Merging Chunks

« on: April 30, 2017, 03:49:26 AM »

 I am having problems with merging chunks.

I have a total of approx. 2000 photos. I broke them down into 4 chunks (so 500 photos each). Everything worked properly, the only problem is that when I tried merging two of the chunks together, one was higher (elevation-wise) than the other.

How do I remedy this? Should I simply merge all chunks together at once? Or one at a time?

General / Problems with Merging Chunks

« on: October 31, 2016, 10:59:23 AM »

 I have four chunks that I've been trying to properly align and merge together. Each chunk is basically a square that consists of approximately 700 images. The first three chunks of images were done about 2 months ahead of time in comparison to the 4th chunk. When I look at the point cloud of all the chunks together I noticed the 4th chunk (the one taken 2 months later) is 'lower' in elevation in comparison to the other three. The result is the orthophoto turning out bad. Some of the areas have doubles (houses, buildings).

Does anyone have an idea of how to merge the point clouds so the elevation is the same?? Is there something wrong with the meta data from the images??

Any help would be appreciated!

General / Ortho Cropping and Post Agisoft?

« on: May 25, 2016, 06:45:34 AM »

 Quick questions...

I was trying to find a way to crop the orthomosaic in Photoscan. I trimmed the sparse and dense cloud but I still get the excess part of the ortho I wanted to clean up. Or do I use different software for that part?

Also, to showcase dense point clouds to be viewed by clients, what software/website is best? Some LAS files I have are about 10GB.

Thanks!

General / Spherical pano WorkFlow problems!

« on: April 03, 2016, 11:16:36 PM »

 I made a half sphere panorama with my UAV. I am trying to stitch the photos together as instructed in the tutorial:

http://www.agisoft.com/pdf/PS_1.1_Tutorial%20%28IL%29%20-%20Spherical%20panoramas%20generation.pdf

I think the problem is when I try and put them into a group and afterwards try to align them. After the process they don't show up at all. The cameras OR the sparse cloud. If I do not group the photos and just run a regular alignment then it works (I see the cameras and the sphere they produced) but I can't 'Export Panorama'.

Does anyone know what I'm doing wrong?? The instructions are really simple and I followed them repeatedly.

Thanks ahead of time!

General / Building Orthomosaic for Forestry

« on: March 29, 2016, 06:50:59 AM »

  I've been working on a few sets of images I've collected at different overlaps and altitudes. I have that part mostly figured out, but when it comes to post processing I wasn't too sure how important building the dense cloud is. Does anyone have some advice on the workflow?? I have imagery from 70% overlap up to 90%. I think 70% is just fine though. I've been building the dense cloud with the highest settings but I'm not sure if it's necessary. I've been told that building texture isn't recommended either and it seems to work without.

Does anyone have some tips?

 Awesome man thanks a lot!! I've heard about QGIS but I haven't played with it yet. You just gave me a lot of good information man I really appreciated it!

After you have your Orthophoto done in Photoscan what do you do with it after?
