Bug Reports / Re: Classify ground points lasts very long

« on: July 12, 2019, 01:27:15 PM »

Sorry for mistake, you are right: dense cloud has 3 200 000 000 points, tie points - 3 900 000

Parameters: 10 deg, max distance 0.3m, cell size 30m. Dense cloud points are located in the area of ~20km2. It is a road that is 35 km long and the buffer is 550 m width.



Update: it took 30 hours to perform a classification in a project with dense cloud 1 300 000 000 points, 10km2, parameters as above.

Bug Reports / Classify ground points lasts very long

« on: July 12, 2019, 08:52:54 AM »

Hello

I noticed, that ground point classification is taking now much more time than it used to. About 6 months ago classification was less time consuming than dense cloud generation. Later I noticed that both consume the same amount of time.

Now I have a project with dense cloud that contains about 3 900 000 colorized points, 8800 cameras  (42 MPix). It took 8h to generate depth maps and another 11 hours for dense cloud generation. Unfortunately, after the upgrade to version 1.5.3. the ground point classification after 10 hours shows me, that it needs 2 days 13 hours more to complete the task. I split the project into smaller parts (ca. 1 500 000 points), but there is no difference in time estimation.  Earlier it was not a problem to work with so big projects.

What could cause such situation? Before I upgraded to 1.5.3. I was not able to generate dense cloud (what has never happened before) due to "Image size mismatch error."

Looking forward to hearing from you.

General / Estimating Camera locations never ends

« on: May 24, 2019, 02:21:27 PM »

Hello

I am aligning 4000 cameras in one chunk and an issue happens: everytime when the alignment reaches "Estimating Camera locations" the process bar stops at some stage, the "time left" slowly goes down to 0 and then dissaperas. After that nothing happens [printscreen in attachement].  When I clikc "pause" or "cancel" buttons grey out and stay like that for ever.
Before that, I aligned 4500 cameras in same project in another chunk with no problem.

Alignment options are 40 000/ 4 000, earlier I tried with 30 000/3 000 - same result.

I attach a log
Thank you for quick answer.

Feature Requests / Re: Export multiple Ortho/DEM sections

« on: March 14, 2019, 12:14:20 PM »

Hello Alexey

Maybe I misunderstand what an attribute is. I checked in QGIS - the attribute is called "Name". There is also a label visible in Agisoft. I attach three pics.
No matter if I change in script "NAME" to "Name", it still exports ortho and dem as "Unknown". Does it work on your PC with provided data?

DEM is exported as RGB and tfw file appeard - thanks!

I have just cheked the script. Here what I noticed:
1. Despite the label marked as "Name" attribute, the name of the created file is still "unknown".
2. When choosing DEM as RGB export the script does not work.
3. Could you add a .tfw file creation when orthophoto export?
In the link I am to send you in a private message You can find the project I test the script on.

Looking forward to getting an answer

Alexey
Have you already worked with the script? I am really looking forward to trying it.
In addition, would it be possible to add a compression choice? If not - please set the default for JPEG 85.
Thnak you!

Hello

I checked the script and I have some requests for update:

1. Ortho export should create also a .tfw file (so far it's just a geotiff)
2. DEM should be exported as either Geotiff RGB or XYZ file (so far its just a rgb geotiff and black and white geotiff)
3. The name of every file should be ortho_label and dem_label (so far I have problems to upload an attribute to kml and read a value from it)

Thank you for help, looking forward to getting the script.

Best regards!

Yes, labels would be also good.

One more thing - when I simply export DEM i get it as .tif, not .xyz. Could you change it?

Thank you again for support!

Hello

Some clients require DEM as .xyz pointcloud file, some GeoTIFF with false colours. Resolution of DEM and ORTHO mostly differs from each other, so I would be pleased to have a choice (it is usually 5cm for ortho, JPEG 85 compression, no alpha channel; and 25 cm for DEM)

I also have problem with proper file naming. I changed the attribute name in script, however it still names files as unknown. In attachement you can find an example of shapefile.

Thank you for your help!

Hello Alexey

I am very sorry for a delay in replying. I found free time to check the script. It works fine, although  one improvement would be also good - script asks for resolution of ortho and dem, script exports dem as xyz or colour pallete.
In case of ortho I also wonder if there is a way to resign from alpha channel.

I am new in python scripting, so some of my questions might have an obvious answer. Looking forward to hearing it from you!
Best regards

Feature Requests / Export multiple Ortho/DEM sections

« on: January 21, 2019, 07:10:37 PM »

Hello!

My company works very often with huge projects (both private and public sector) where I prepare DEM and Ortho for big investments like highways, quarries etc. As I result I am expected to provide a lot of maps' sections which are usually used for projecting process. Currenty I am working on 100km of highway where as a result I will prepare around 400 sections of maps 1:2000 - ortho and DEM just for investment preparation. To do it I need to set a outer boundary separately for every section, check the export options, name it properly (ortho_6_142_25_03, dem..., etc.) and eventually save. It can take up to 2 days of work.

It is not a problem to prepare a shape with name as an attribute. It would be perfect if I just selected multiple boundaries, then used option like: "export multiple", "name after attribute..." and after few minutes/hours I would have all sections automaticly exported. Have you already taken into consideration such feature?

In attachement you can find the example of investment, where I need to export every section separately.

Thank you in advance for reply!

General / Re: Out of memory (2) at line 179 after upgrading to Metashape

« on: December 22, 2018, 12:12:07 AM »

Hello Alexey,

I downloaded driver from official site and installed it. However, the problem still appears.
In addition, it is not a problem to generate for example a dense cloud, dem or ortomosaic in other projects I alligned before the upgrade. The problem appears only with alignment. In attachement you can find another log (alignment after driver update).

I use Windows 10 Home.

General / Out of memory (2) at line 179 after upgrading to Metashape

« on: December 21, 2018, 10:47:15 AM »

Hello

I have a problem with my Agisoft (error: "out of memory (2) at line 179") after upgrading to version Metashape 1.5.0.
Before the upgrade I processed usually 4000-7000 or even more photos in single chunk without any problem. After upgrading to Metashape it turned out that during the alignment of ~2500 photos described error appears. I downgraded back to Agisoft 1.4.4. but it did not solve the issue. In attachement you can find two logs - one is from Metashape where I try to allign around 4500 photos, the other is from downgraded 1.4.4 where I got error during aligment of ~2500 photos.

I am really looking froward to getting an advice as the problem seriously decresed my effectiveness.

Thank you in advance.

General / Re: Exporting DEM after color palette change

« on: December 18, 2018, 11:48:22 AM »

I have already downgraded back to Agisoft 1.4.4. 64x. Unfotunately, the error still appears: Out of memory (2) at line 179 - every time the same no matter which project I allign. I wanted to align cameras on high (key point: 40 000, tie point: 4 000). The number of cameras: 2482.

If you could work out the problem here, I will retun to Metashape and check it again. Thanks.

There is an issue with new Metashape. With previous Agisoft 1.4.4 for 64x Windows it was not a problem for my PC to handle 5000 cameras alignment. Now I recieve "out of memory" error when I try to align 2500. Have you already got some feedback about it? How can I cope with that?
