General / Camera Alignment Settings

« on: September 09, 2020, 07:36:06 PM »

Hey guys,

I'm still working on my little project of scanning an apple.
I'm jusing a studio light setup and mask the apple.

I already got a decent result with the settings I used during the camera alignment and after this using the "reset camera realignment".
If I wouldn't have used the reset command my pointcloud looks kind of wrong.

So my question is what kind of settings are you using to get the best camera alignment in the first run. Or what would you suggest in my case. Current idea is to scan a lot of veggis and fruits.
Thanks for your help guys.


I attached a screenshot of my settings, the masking of a photo and the result.

General / Camera Alignment

« on: September 02, 2020, 05:50:32 PM »

Hey Guys,

I have a question regarding the camera alignment. Maybe you can help me out.
So I used agisoft two years ago and did some test and they worked quite well. So know I wanted to start scanning objects like fruits.

My first try was to use an apple.
I have a small lightbox and a Canon eos7d with a standard camera kid (18-135mm).
I took some pictures inside the box and masked the apple out in Agisoft.

For some reason the alignment isn't working right.
Is it because i turned the apple around and took another row of shots. But then I dont understand the use of the masks.

Tried different setting for keypoints and tie points.

I attached a Wetransfer link to see some screenshots:

Thanks for any help.

Hey guys,

I read the user manual of Photoscan and cant still figure out what the Tie points in the allginment step are ?

Could someone explain what they are doing, is it just a filtering methode of bad points?


Cheers!!!

Hey guys,

I was wondering how to get better a better resoultion of the texture of my model.

Is it better to shoot more rows of my models and some additional cloes up pictures or does it just rely on the mp of my camera ?


Thanks for your help !

General / Camera alignment at one spot

« on: May 02, 2018, 08:38:49 PM »

Hey guys,


I found some related topics in this forum, but i couldn't find a working solution for my problem.


Okay so, I tried to make some photogrammetry test inside a studio setup.
After that I wanted to use the test inside Photoscan but I ran into an issue with all my pictures except one.

When I align the cameras all cameras appear at one spot, so it looks like agisoft cant figure out where same spots of the model are.

I did a plane background image of all my rows but still the mask isn't the best.
 


with all the other models I hadn't had some stuff on the lazy susan.  so it was plank except for the marks at the corner.


Thanks a lot for help !
