Hello, I am a student studying Land Surveying and I am currently doing a project about close-range photogrammetry by using ContextCapture. I am doing an indoor surveying in a house. Since separate models are generated from one house and they are going to be merged after reconstruction, may I know should I create control points for them for geo-referencing? Also, since I am using .obj file for this project, is it possible to export the local coordinate system of the model if I use control points? Thank you very much!
For modelling house it is better to stay in local coordinates. You can create so called fake GCPs so it stays in some arbitrary local coordinate system but aligned to axis.
