I found that some photos cause problems, so what i tried to do is to align 20% of the Object/model let say the first 200m of your road and after alignment is good I add more photos and do align again until I found where is the problem. (probably some photos with an angle or lack of overlap)
I’m coming from the 3D scanning industry and what could be a nice feature in RC it’s if after alignment there could be separate groups of point cloud that had a problem of alignment and we could decide if we need them or not and then register them.
Currently that way of work that you will receive the biggest model or a broken(with distortion) model that consist of different parts that not aligned well - it very frustrating to start all over again - the best to put it in separate models and then with cloudcompare i could merge them.
What I mean is: many times you have some photos that couldn’t align especially if you combine pictures from the Drone and from the SLR (From the ground) - what happening in the background that there are a few Segments (Groups of Tiles Points) and the software doesn’t really know how to align between 2 different sets of photos. (I’m talking about the automatic process with GCP)
The Solution in the 3D scanning industry is doing it Manually or Semi-Automatically - register that Group of clouds and receive the full model.
I can explain better if the developers would like to improve that alignment of different sets…
