Hello tweezlednutball,

Thanks for reporting.

It will be fixed in the next 1.4 update.

Hello!

You're welcome, looking forward to the next update!

Bug Reports / Import Cameras XML broken in 1.4.0 build 5310

Cannot import cameras in latest beta.  Works just fine in 1.3.4 build 5067.

Feature Requests / Re: Generating Dense Point Cloud - OpenCL Acceleration?

« on: October 24, 2017, 12:56:51 AM »

Currently GPU can be utilized for image matching (first step of Align Photos stage - includes feature points detection, pre-selection and image matching itself) and depth maps reconstruction (first step of Dense Cloud Stage).

Version 1.4 is using GPU for Mesh Refinement operation and during the new Build Mesh method (also for depth maps reconstruction step).

Other processing steps are performed on CPU only.

Yes I understand.  What I mean is it possible to make the second step of Dense Cloud GPU accelerated?  This step has become by far the largest compute time of all regardless If the most high end CPU's are used.

Feature Requests / Generating Dense Point Cloud - OpenCL Acceleration?

« on: October 13, 2017, 05:22:25 PM »

Hello everyone.  As we all know the generating dense point cloud step is now the longest step regardless if you have 2X Xeons with much ram.  I was wondering if this step is possible to also run on GPU's?  Thanks!

General / Re: Cost of airborne LiDAR ?

ive scanned most of the major cities in the world using photoscan 

"Scan" implies an active active sensing method, which is not an accurate term for photography. You computed a statistics based pixel matching model for those cities, you did not scan them.

Whatever you want to call it, if you know what you are doing the results can be amazing and guaranteed to be far less expensive.

There seems to be a bug when importing cameras from xml, setting the key and tie points always ignores the settings and defaults to 0,0.

Feature Requests / 16 bit EXR image support Standard Edition

« on: November 19, 2013, 04:23:02 AM »

Seems a bit silly to have 16 bit tiffs supported but not EXR's.  I would prefer to use EXR because I can embed an alpha channel and the compression is much more efficient than anything when it comes to alpha channel and solid colors.  (when scanning objects im creating masks in nuke and also filling the masked areas black.  I was testing file sizes and my EXR's were roughly 10 times smaller file size with same bit depth.

Thanks keep it up!

Its been like this for as long as I can remember.  I also posted about it some time ago.  Not sure if it causes any performance decrease...

General / Re: How to overcome RAM Limitation

I have mentioned this in the feature request area where the bounding box could be subdivided and each piece process separately and then combined at the end.

Feature Requests / Re: Reducing memory load for high/ultra quality settings

« on: August 11, 2013, 07:55:36 AM »

What we are doing is manually creating separate chunks and creating a mesh for smaller areas of the entire mesh, then combining meshes afterwards.  Its slow annoying and clunky but it works.

There could be an option for creating blocks inside the bounding box to mesh separately and combine at the end batch style.  Would probably be a lot easier to program rather than adding new API's and changing the meshing algorithm.  I also noticed that OpenCL 2.0 has support for depth maps now so maybe we could see some implementation of GPU acceleration for meshing?

Bug Reports / OpenCL not all VRAM detected

« on: March 06, 2013, 11:57:22 AM »

Hello.  I am running the latest pre-release Version 0.9.1 build 1640 (64 bit).  In the OpenCL options it lists my 2 Radeon 7970 GHz Edition's as only having 2048MB of memory when they do in fact have 3GB.  I also have another machine with a reference 7970 which also displays 2048MB.  I can imagine this would make sense on an nVidia card which may have a split 256/128 bit bus, but the Radeon's have a full 384bit bus.  It might also make sense why I am only getting 75% GPU utilization.  Could this be an issue with the OpenCL drivers?  I am using OpenCL drivers 12.4, when I have time I will try with 12.8 and report back.

I guess it was a false alarm.  I restarted my computer and now I am getting activity on my graphics card. 

Maybe you should incorporate a restart after the installer completes?  Thanks so much for the help.

Feature Requests / Re: high frequency noise reduction

« on: July 20, 2012, 12:27:06 PM »

having more photos/points would create less noise.  Also, we use Neat Video Noise Reduction tool if our photos are noisy which may produce noise in your mesh.  from there we use photoshop batch mode to reinject any EXIF data back into the images.

Tried batch mode.  Not working either.
