Hi,
I am wondering if it is possible to do some kind of 3D rectification in GRASS GIS based on multiple simultaneously captured photographs from different positions/angles. In other words, assuming one has 3 photographs of an object from 3 different angles. All of the photographs include common reference points with known coordinates (X,Y,Z). How can one extract get/calculate the 3D-coordinates of a point of the object that is visible in all 3 photographs?
Probably this is not a task for GRASS GIS but maybe someone has done something similar before. Any hints are welcome!
Best regards,
Johannes
