General / Re: Experimental Mesh Generation Stuck on "Estimating Best Cut..."

« on: September 01, 2018, 05:48:12 AM »

Thanks for the quick reply!  This is what the log is giving me (everything other than a whole lot of "[GPU] estimating")

Depth reconstruction devices performance:
 - 49%    done by GeForce GTX TITAN X
 - 51%    done by GeForce GTX 1080
Total time: 9947.72 seconds

Dense cloud accumulated in 9962.54 seconds
Building model...
Setting weights for cameras...
Inspecting edges...
Setting weights for visibility rays...
Rays traversed in 4325.8 seconds
Cells number:  363360940
Additional weights calculation...
Constructing graph...
Estimating best cut...

The project is a full 360 degree environment with 430 separate 3000x2000 images which I understand is hefty.  Detail settings were all the highest possible.  Right now it's sitting at 27 hours which is a time I'm okay with, I just don't know if it's going to be 3 more days after this lol.

General / Experimental Mesh Generation Stuck on "Estimating Best Cut..."

« on: August 31, 2018, 08:14:58 PM »

I've been using the experimental mesh generation method to create a mesh after getting repeated index overflow issues with the traditional method, but I'm currently stuck at "Extimating Best Cut..." and it's been there about 18 hours.

Does anyone know if this part of the process happens to be single threaded and CPU based?  Nothing is being used but about half my ram and 4% of my CPU.

General / Re: Best Way to Add More Points to Dense Cloud?

Hi Sav,

Thanks for the response! 

Currently I'm already using the highest quality setting for the dense cloud that I'm able to, unless you can some how specify something higher than the Ultra High preset. 

The workflow I have going on kind of revolves around avoiding mesh building so I'm hoping to stay away from that if at all possible.  I have processing power to spare...  My main concern is time since I'm going through this process with a whole lot of scans.

Cloud Compare is one I've never heard of so I will definitely look into it and see if there's anything it can do that will help

General / Best Way to Add More Points to Dense Cloud?

« on: March 27, 2018, 06:35:15 AM »

I'm trying to get a denser point cloud to work with and I'm wondering how to best go about it.  It's not that i'm trying to get more detail, just that I need more actual points being placed before exporting the point cloud to other software.

Does anyone know how I could do this?  Best way I could think of is just to increase resolution in the source images but that seems wasteful in terms of processing.  Is there anything equal to "Refine Mesh" for dense clouds?  Maybe something like "extrapolate more points from neighbors"?

General / Windows OS Laggy While Building Clouds (Regardless Of Free Resources)

« on: July 04, 2017, 09:11:52 AM »

I've been building some dense clouds with Photoscan Standard and noticed how completely unresponsive Windows is at times, often with the mouse cursor slowing down to like 1 movement per second.  Web videos stop playing, apps freeze and all that other stuff that comes along with process intensive programs...

Not all of my resources are being used though.

I have a video card dedicated to running windows (my display card is a GTX 1060 and I have two 1080s used for rendering and processing).  There are a number of GPU rendering apps that I use in this way and because my display 1060 isn't used for rendering there's nothing slowing down the video processing for Windows.  Everything stays running just the same when I render as when I'm not.

The CPU for Photoscan has it's affinity set to 4 of my 8 cores so my processor load for the cloud building is never above 50%.  I've also set the process priority to below normal without any changes.  There should be enough free CPU overhead that Windows shouldn't be lagging like it is.

Memory wise I have 64GB in this PC and Photoscan is currently only using 5GB, so it's not a memory issue at all.

Does anyone know what might be causing the lag issues?  Currently Photoscan is really the only program I use that does this sort of thing.  I'm very used to multitasking without any problem, sometimes even rendering with CPU based software like Vue while rendering with GPU software like Octane at the same time.  Based on my system performance I really shouldn't be kept from at least watching Youtube while clouds are built.

General / Re: Method For Masking Out Sharp Pixels?

« on: November 16, 2016, 02:28:48 AM »

That was a brilliant idea!  Noise does seem to be a hurdle but the process works well.  This is what I'm doing...

1. Open original image
2. Duplicate layer
3. Apply 0.3 pixel gaussian blur to duplicated layer
4. Set blurred layer to "Difference" blending
5. Copy result to new layer
6. Levels filter on results to increase contrast
7. 4 pixel blur on results to expand area of difference (it comes out speckled this helps make it solid)
8. "Threshold" on results to remove any gradation in mask

I've yet to put them through Photoscan but it's giving me the info I need to work with.  Thanks!

Thank you for the reply!  That sounds exactly like what I need.  Though I'm disappointed to hear that it's only in CC (I currently work with the boxed version of CS6)...  If you or anyone else knows of other ways to "Select Focus Area" that would be great.   Otherwise I'll have to think about finally making the change to Creative Cloud lol

General / Method For Masking Out Sharp Pixels?

« on: November 13, 2016, 07:55:23 PM »

I'm wondering if anyone knows of a way to create a mask based on the sharpness of pixels in photos used for generation, either within Photoscan or through 3rd party applications.  With my scans even at the highest aperture (f22+) I'm having some trouble with depth of field.  Not so much with the 3D model generation but with the texture creation.  Regardless of there being sharp "in focus" information for every part of the model Photoscan tends to also use the blurry "out of focus" parts when putting the textures together.  If there was some way I could tell Photoscan not to use those portions it would be awesome (as far as I know masks can't be used for textures so I'm guess it would be done with image processing).

I came across this thread with the same issues and they suggested a tool used to detect image sharpness, but I'm hoping for a Photoshop method etc that will detect a feature as sharp and map it as white while blurry portions get set to black or transparent.
