General / Cameras not aligning
« on: April 21, 2020, 06:32:01 AM »
Hi, I have been trying to teach myself Photogrammetry of 3D objects and it's fair to say it's driving me a bit mad!  My attempts have generally been sort of ok, but with quite a few holes and sections that haven't resolved very well.  I'm keeping the camera stationary and rotating the object.  For each different camera view I'm taking a shot without the object to then create a mask with.  I have Apply masks to Tie Points selected when aligning photos.
Suddenly yesterday I developed a new issue where large numbers of photos aren't aligning.  I'm selecting them, resetting alignment and then aligning selected cameras.  I've tried this as a group and individually but it's not working.  I have no idea what I'm doing wrong, especially as this is a new issue that I wasn't having before.
I've attached 2 screenshots.  Any help gratefully appreciated! 

General / Aligning turntable photos using tie points
« on: April 14, 2020, 05:22:43 AM »
Hi, I have a month long demo of Agisoft and am trying to learn now to create 3D models.  I have photographed an object by rotating it 360 degrees with the camera at 4 fixed heights.  For each new camera view, I took a photo of the background without the object so I could align the photos using the 'Apply masks to Tie points' feature.  However when I go to align the photos the 'Apply masks to' drop down menu is greyed out and set to 'none'.  Is this because I'm using a demo version or is there an easy fix?  Thanks.
