Bug Reports / Re: Same location UAV images aligned flipped ?

« on: January 31, 2019, 02:43:26 PM »

Hi , Thanks for looking into this.

Where do I see this information  ? Just so I can confirm other photo sets .

Also can I confirm this by looking at the raw dng files ?

To understand , the alltitude information from the DJI Mavic 2 is then not provided in the images ?

Does the script need anything else than access to the original image files ?
https://forum.dji.com/thread-171969-1-1.html?page=2
Sorry for all the questions but really need to understand how to sort this out for my project.

Would it be helpful if I provide you with a sample raw image from the flight ?

If it could be any faulty format provided by DJI ?

Johan

I found this topic and seem to be issues from DJI firmware!

https://forum.dji.com/thread-171969-1-1.html?page=2

Does the provided script help sort theese issues ?

Its only important to get the alignment correct , even if height doesnt match realworld height.

Bug Reports / Re: Same location UAV images aligned flipped ?

Hi , thanks for the reply.

Ok , would it be fine without the images due to size ?

I’ve been doing some more testing with trying to align UAV flights .

The gps info provided for each flight provide the basic layout, but
when aligned together they won’t  line up.

Align them sep work fine , but then align chunks to combine them in the end but
will result in 2 layers pointcloud in different areas of the scan.

Realign all with no reference and reset makes many different weird parts in space.

Do you have any understanding how this could happend?

There is plenty of overlap on the images.

One set is nadir and one set is nadir +30 on the same area.

It is as it’s not trying to align the images visually anymore and the gps info override it in a faulty way.

From no additional info I would expect it to do a regular alignment.

Await your reply how to proceed

Bug Reports / Same location UAV images aligned flipped ?

« on: January 22, 2019, 08:12:09 AM »

When doing 2 UAV captures at diffrent heights agisoft wont align cameras.

The 2 diffrent images series alignes flipped as if diffrent objects.

The images are off the same area but was captured 30 min appart. Same lighting conditions but seem geo referenced data is mirrored or offset somehow.

Any clues what could be wrong and how to make align as one series of images ?

The mesh is now not in chunks to see if the pink texture was related to. Which didnt solve the problem.

Hi , yes the mesh is purly for baking from and needs to be as high as possible for getting best quality normalmaps etc.

Yes Xnormal doesnt have any problem with mesh sizes.


Thanks for looking into this

Hi , sorry for the somewhat late reply but run into the same problem again and have the files needed to show what happends.

Any clues why this turns out so wrong ?

All in all the texture and vertex color look good, but using the default delighting setting (multi color) and no AO makes it faulty.

from the log with lighting removal

and also seem to be alot of this:

Hi Alexi

Thanks for the help with looking into this.

I tried rebaking pointcloud now at highlevel instead of ultra high.

But now the Removelighting got BadAllocation.

I include my log here of the entire history.

Let me know if I can do something diffrently.

Hi

700 images 12Mp
250 Milj Pointcloud UltraHigh

I run into bad allocation using the new meshing method also.

So guess its out of memory.

Would it be possible in future to get cashe to prevent this ?

General / Cant build Mesh ! Help

« on: December 30, 2018, 02:43:51 PM »

Hi

I need to get a mesh from my dense cloud but doesnt seem to work.

Building mesh = bad allocaction
Split in chunks = edges wont lineup
TiledMesh = Turns out lowpoly
New Meshing method = Bad allocation

I really need to keep the detail of the mesh point cloud.

128GB ram

Tried exporting pointcloud but cant figure how to mesh it elsewhere. In Meshlab ex no point
show up using xyz format.

What other options do I have ?

250milj pointcloud so nothing insanly high.

I so wish Agisoft would support cashe , a bit frustrating
to get stuck on this all the time

Any help on how on a worksround much appriciated.

Hi , here are some thoughts on things I know many would like to see in future edition of the Software.

Have Agisoft use Cashe to Balance Memory demand.
For example dedicate a 1TB Nvme Disk for this only

Tiled Building. Have the software split the task into smaller ones.
Have a look how Global Mapper deals with this. This way all smaller tiles meet the demand of the computer.
This way projects can be of 10TB pointcloud but are divided up.
Same goes for export. Export as single file or tiled files depending on how much resolution is needed.
At work I dedicate 1TB cashe for this. Let me know if you need more info regarding this.

But a more automated way of dealing with this is much welcome based on a few presets.
Maybe this can be controlled on the amount of overlapping photos allowed?

What’s your thoughts on this ?

Regards Johan

General / Re: Chunk mesh seems?

« on: December 29, 2018, 03:39:44 PM »

I had time to read trough some forum posts covering same topics.

It seem to me that the solution is to have 10% overlap but when exporting shrink the chunks bounding boxes back to original size, depending on if Agisoft only export what’s inside of bounding box. This would then be as a crop and chunk meshes would then align .

Question 1 : Does export only take what’s inside of bounding box?
Question 2 : is there a Phyton script available for scaling bounding boxes down?

Calculating Mesh now so can’t  do any test at the moment of writing this.

General / Chunk mesh seems?

« on: December 29, 2018, 01:58:54 PM »

Hi , when splitting a scene into diffrent chunks with overlap of 10%
the meshes dont match at the overlap.

What would the prefered workflow be to avoid this?
Shrink the bounding box down 10% before exporting mesh?

Any help on this much appriciated.

Hope not to have to rebake
