General / Re: Orthomosaic deformation of images
« on: February 28, 2018, 11:54:12 AM »
Hi Alexey,

could you give me a quick answer to my question please?
This is something we need to solve.
It seems that the whole image looks like the residual plot of the lense.

Can I somehow just use a 6 parameter transformation onto a flat plane?

Thanks for the reply. They are pretty good aligned using GCP's with an accuracy of 3 mm  GSD.
Even when they are missaligned the images would be projected using 6 parameter transformation. This usually never adjusts parts of the image in different directions.
Is it possible that the rolling shutter compensation has something todo with this?
The images itself look straight though.

General / Orthomosaic deformation of images

Dear Team,

when I want to generate an orthomosiac sometimes I'm using the Mesh generated from the Dense Cloud but sometimes I'm also using just a flat plane (a big plane importet from a different software with only 2 big faces). This helps me to project the images on to a flat plane.

Now my problem is that the images projected onto a flat plane are somehow bended.
See image below:

Why do they bend? Can I somehow prevent that effect? I only want to have the effect of radial distortion in it. it seems that there are more effects.

EDIT: It doesn't matter which image I choose using "replace image" via the selection. They are all bended

I'm using just a big flat plane to project all the image onto it.
The problem is that this kind of workflow never used to be an issue before.
The next facade for example doesn't give me those projections

Hey Alexey,

i have a problem with updating orthomosaic.
In picutre 1 (see attachement) I have a wrong image. I switched it using "assign images" (image 2 in attachement) and then I updated the mosaic. After that It looks exaclty like picture number 1.
Why doesn't it keep the image I assigned?

EDIT: hole filling is disabled and no backface culling
I even masked the background (sky)

That seems to be it!!
Thanks Alexey!

General / Orthophoto with direction of marker on DEM
« on: February 01, 2018, 07:34:37 PM »
Hey guys,

I just created a DEM using 3 markers. Now I would like to project the images onto the DEM using the same markers. I dont want to use the Mesh because its a facade and the DEM will give me better results than the free mesh.
The problem is that I can't choose DEM when I open the Orthophoto promt and select the projection plane to markers.
Why is that and are we able to use it in the future?

General / Mirrored Orthophoto of ceiling
« on: December 11, 2017, 04:03:43 PM »
Dear Team,

I have a specific problem I would like to solve.
I took pictures of a ceiling and we used a laserscanner to scan the whole roof.
After meshing the scan we were able to project the images onto the laserscaned mesh.

We used GCPs and now comes the tricky part. Is it somehow possible to project the images onto the mesh so that when you look from the top onto the roof, you will get to see a mirrored version of the roof?

We would like to combine the orthophoto with some aditional measurements but the customer wants the orthophoto from above but mirrored.

Any ideas?

Hey Alexey!
thank you for the quick support! It works with the new release!
Keep up the good work and have a great day!

hey I just send you a link with the data via mail

« on: November 27, 2017, 05:49:45 PM »

i can't export the points from my chunk.
I duplicated my chunk to calculate a different part more precicely and now I'm not able to export the points from thank chunk. all other chunks are fine but this one chunk which has only a high calculation instead of the middle wont export.
I tried any format. Always: Invalid data type

Hey dear team,

I need to know where you put the "gradual selection" in the pre-release 1.4.0?
Thank you ;-)

Hey Alexey,

yes I had somehow. I deleted them and now I'm able to export them!
Thank you!!
