Hey guys first post. I have been able to get to where I am with searches and a couple questions on the FB group but I decided it's time to join the community as I need a little more help with a few things. Right now it is scaling my current model.
I have a big model I am working on with about 2000 pics. UAV and ground. It required a quite a few control points to get them to tie together and decent alignment but it's looking pretty good now. This is a lot I will be putting a modeled building on and so I want to scale the lot model. I used two control points between two fence posts I measured, defined the distance and ran alignment again but it doesn't change to what it's supposed to be. The defined distance is 5.2 meters. The actual distance before adding the constraint is something like 5.8. Once I add the constraint and run alignment it goes to something like 6.1. If I then change the value from 5.2 to anything else and update the calculated distance increases. So for example I changed the defined distance to 3 meters, updated, and then it said the calculated distance was 6.1 meters. Then I tried 7 meters and it changed to 6.6 meters. After that any value I enter only changes the calculated distance by a couple hundredths of a meter.
I opened a small project I have been working on with a couple hundred photos, arbitrarily selected a couple of control points, added a defined distance, ran align again and the new component reported the calculated distance the same as the defined distance. Why isn't it doing this in my bigger model?
