General / Re: Bad Texture after removing and regenerating texture

« on: February 19, 2020, 04:15:16 PM »

Updated drivers and regenerated the texture and it's fine now.

Not really sure what caused this at all, but happened to a number of different models. I'll let you know if it happens again.

Thanks Alexey,

Source images are DNG, the first texture that gets created is perfect. It only seems to happen when I right click and "remove texture" from the model, and then generate it again.

Oddly, the GPU didn't seem to get utilised for the texture building, even though it is a GTX 1060 with driver version 432 (I am now updating it to version 442). I noticed high CPU usage, but no major GPU usage. I'll retry when this driver is updated.

General / Bad Texture after removing and regenerating texture

« on: February 19, 2020, 03:05:35 PM »

I have a number of models decimated to different face counts. When I remove a texture from one of these models and recreate it, frequently the text appears badly calculated, as shown in the screenshot below. The object is a bone, you can see the correct texture colour in some spots. The white lines are the edges of the texture segments in the UV map and should not be visible either.

I am removing the UVs before regenerating the textures, although I have moved from 4 x 4096 tiles to 1 x 8192 tiles.

Using version 1.6.1

General / Re: V 1.6.0 - Dense cloud generation time longer, increased noise

« on: February 02, 2020, 06:41:34 AM »

Any information on what is creating the noise?

I'm getting similar surface noise in 1.6.1 compared to earlier versions (1.4)

General / Low number of depth maps produced resulting in missing surface

« on: December 18, 2019, 02:11:44 AM »

I have some scans I am reprocessing in version 1.5/1.6

When these were processed previously, I was getting 334 depth maps produced for 334 images (1.3). In 1.6 I am getting just 240 depth maps produced for the same set of photos, and this is leaving huge holes across my model. This happens whether I just do a "Depth Maps" mesh, or create a dense cloud for the model.

My parameters are Ultra-High, High, Mild with Interpolation turned on. All 334 of my images are aligned (Highest, no pairing, adaptive fitting).

I understand that some images are not used for depth mapping, but I would not expect the system to ignore images for which there is no overlap.

Edit: I ran a test without removing points using "Gradual Selection" in the sparse cloud phase and it seems to have generated Depth Maps for 325/334 images.
What are the criteria for whether Depth Maps are calculated from an image or not; so I can still optimise my alignment but don't remove so many points that the image is ignored?

Select by point is not working how I would expect it to.

Build 9397.

I create the sparse could and see that I have sections which are mis-aligned.
I select some points and press "Filter photos by point". I correctly get a dozen cameras. I reset them and re-align. All OK.

I then see some other points that are not right and select those and follow the same procedure.  In the "details" list of the photos I get a list of several cameras. However, if I Ctr-A them or even select them individually and do "Reset alignment", I am told it's going to reset far more cameras - in fact, I believe the set of cameras to be aligned each time is the summation of previous selections and it is not being reset when a new "filter by point" is done.

...

I've had the same bug that has been in every version since 1.3? The problem is that the left hand list of photos retains the previous selection when you use the filter or even just select a range of photos in the "Photos" window.

I work around it by looking for a photo from the filtered list in the left hand list, manually clicking on it in the left hand list, and then performing the mouse drag selection in the filtered list. This always gets the correct photos for realignment.

Note: I did re-report this bug recently so it may be you have a slightly different issue.

Feature Requests / Re: option to not reset view after processing step.

« on: November 13, 2019, 11:40:52 AM »

This would be really great. I am manually aligning 200-300 photos 2 at a time and focus on an area so I can see what changed. I have to refocus the view after each alignment.

It would be great if it didn't reset after "Optimize Cameras", too.

Bug Reports / Selecting photos in Photos windows doesn't always select them in Workspace

« on: November 12, 2019, 12:57:33 PM »

This bug has been there forever, but it's driving me nuts because I have had to process around 10,000 photos in the last month or two.

When you select some photos in the bottom tabbed "Photos" window, the same photos are not always selected in the "Workspace" window. This means that if you filter some photos and select them and right click and select "Reset Camera Alignment", it's not the photos that you have selected that become reset - it's some other photos in the "Workspace" windows that are selected and reset.

If this could be fixed, it would be save me a lot of my coins going into the swear jar...

Cheers

General / Re: Import Mask - smallest area to mask

Any advice here?

General / Import Mask - smallest area to mask

« on: August 29, 2019, 11:17:55 AM »

I use masks heavily against a green-screen background. When I import the mask, I just import a single coloured image and let Metashape automatically mask my image.

I've noticed that small areas of "Green screen" do not get flagged as masks, though. Imagine a cup with a handle on a turntable. The gap in between the handle and the cup will get masked if the cup is perpendicular to the camera, but as the cup rotates and the empty area in between the handle and the cup gets smaller, there is a point where the software will no longer apply the mask even though a good deal of green-screen is still visible.

Is this a setting somewhere that I can adjust?

General / Re: Low Resource Usage in new setup

« on: February 12, 2019, 01:20:28 PM »

Thanks Dave,

I actually posted the wrong screenshot - I meant to post the one which had the Compute objects shown.

What I just realised when I went to recreate it, is that there is also a CUDA object now. I think it must have been added when I updated the drivers. Originally my performance monitor layout had the various compute objects, and the total GPU chart showed close to 100% usage. When I ran the next model, it must have updated something as the total GPU monitor object is now at 4% and the Compute charts show no activity.

However the CUDA chart is jumping from about 50-90% while processing. I think this must have been a driver change that has changed the chart object display.

Thanks for pointing me in the right direction.

General / Low Resource Usage in new setup

« on: February 12, 2019, 09:43:00 AM »

I have had to partially rebuild a computer, specs are basically: Intel I7 8th Gen 4.2Ghz, 48GB DDR 4, nVidia GTX 1060 6G.

I processed one set of images, and the alignment stage was nice and quick, however I recently went to process a second set (375 x 24MP JPEG) and the alignment stage seems to have slowed. I opened resource monitor and also nVidia monitor, and the GPU is barely being used - sitting at 4%. CPU and RAM usage are also low - in fact the system doesn't appear to being fully utilised at all.

Anything else I can check?

General / Re: Agisoft PhotoScan 1.3.0 pre-release

« on: February 07, 2017, 12:52:20 PM »

Latest version of 1.3 seems to be working well for me. Just one thing I reported before that is really annoying.

When using the "Gradual Selection" tool in this version, you need to click on the model window once after gradual selection and before pressing delete. If you left a selection tool on, this deselects the "gradual selection".

Previous versions returned focus to the model window after the gradual selection dialog is closed. I run gradual selection sometimes 15 times on each model - if you could make this work again I would be very happy.

Thank you.

Feature Requests / Export Units to PDF

« on: February 07, 2017, 12:48:50 PM »

Is it at all possible to add the exporting on units in PDF format?

Units are in metres in Photoscan but when exported to PDF they are in "model units" and I have to edit the PDF to change model units to metres.

Thank you.

lunar - are your GPUs still ticked under preferences now that it is working?
