alignment results changes
Answered
Hello fantastic results from the software but my issue is the alignment results for the cameras change--either one half or the other half of cameras tend to align. In Agisoft the cameras aligned and a full model was generated, but in RC the results are misaligned or missing but the model is shockingly more detailed and noise free.
Is there a setting I should experiment with in RC to improve results or is AGI just more forgiving when it comes to quality of photos it chooses to use?

Hi Alex
For the alignment we set the alignment algorithm a bit strict. but it is perfect for understanding what is not properly captured. so if RC does not manage to align the model, then inspect it and try to find out why ( not systematic capturing of images, not proper overlap, low image count, too high angles among cameras )
If this happens, we recommend you to acquire additional images or use control points to get it together -
It's possible to import bundle out scenes + undistorted images. If you can export that from Photoscan then you should be able to import them.
We are using a different camera lens distortion model from the one used defined in "bundle.out". We are taking just a camera rotation, a translation and a focal length. It is assumed that all input images are undistorted. -
thank you for the replies. i inspected the camera positions on AGI to what was aligned in CR and it is clear it has to do with lack of overlap for the photoset i was using. the one side that was covered well shows up and the other side that is a bit haphazard misses alignment which explains things a bit better.

Hi Götz
to importing BUNDLE.OUT
export it from agi as project_name.out + undistorted images there
in RC use the LOAD dialogue and set the bundle.out format for loading
you need to use JPGs for the images, any other format causes issues
the main problem here is you need that ALL images are aligned, if they are not, you will get into issues
to export from RC
ALIGNMENT ribbon / REGISTRATION tool and set the bundle.out format
use the JPG as the export format of images -
I'm trying to import the bundle out (.out) file exported from agisoft along with the jpeg images but I get this error. Can anyone help me what I'm doing wrong?-

It is possible to export bundle.out only for sparse point cloud + camera poses. This can be done using WORKFLOW\Export\Registration and select "bundler" format in "save as type" combo box.
Thanks martinb.
Only sparse cloud?
Hmm...
Suppose I could do that and also export the mesh.
I assume it will keep the orientation (coordinates) when I import both in another application?
I will try it soon and get back to you... -

on export of undistorted images use this {filenum}.{fileext}
in the FILENAME TEMPLATE
I have 481 images, all aligned in photoscan. I tried the {filenum}.{fileext} and it creates files starting from 0.jpeg down to 481.jpg but now when I try to open the .out file in RC it asks for the original file name of the images which was DSC_xxx.jpg and I get a load window to select one by one all of the 481 images :D
any other more simple way to solve this? -
Hi George
You are doing something not correctly :D
so step by step
1. first export cameras in BUNDLE.OUT from agisoft
2. UNDISTORT the images but change "{filename}" to "{filenum}", otherwise it will not work !!
run RC
OPEN the project
select the BUNDLE format to be read
and get it done...
if you get stuck somewhere, let me know... -

I tried again, I'm following your steps exactly but the problem is that RC asks for the DSC_001.jpg, DSC_002.jpg... file naming and not 0.jpg, 1.jpg etc. that agisoft created using the new {filenum} command. I can point RC to load each file one by one but this is not a good option :lol: maybe I should rename the original image files from the camera , import and align them again from photoscan to have the correct file naming RC asking , unfortunately it takes time to do the process again, its not lighing fast like RC :) -
Hi George
when you do it the right way, it is just like loading a project and you do not even need to set the file location...
try the last thing - place the BUNDLE file next to the undistorted images and try to open them in RC.
If you have TeamViewer installed, we can take a look at it in the morning... -

finally this was the trick! I moved the .out file inside the folder with the imgs and RC loaded all of them! :D
thank you!! -
Götz Echtenacher wrote:Hi George,
Just out of curiosity, why don't you align them all in RC?
It's probably quicker than moving the images to another folder... :lol:
good point :) but I'm doing this because in this specific project the RC could not align all the images , even after some tweaking from the settings while photoscan could align all of them. -
Hi George
can you PM me at muzeumhb@gmail.com with some screenshots of the problematic alignment ? -
