The purpose of the project was to create a mosaicked orthophoto and 3D model from orthorectified images in order to measure objects in three directions.
The overall workflow started from measuring Ground Control Points, that were ordered in a way with 60 and 30% of overlaps in lengthways and crossways. Then, internal and external orientation were done for camera parameters calibration and adjustment of image coordinate and ground coordinate systems. Further aerial triangulation was performed for a creation of tie points and further point clouds. Additionaly, from orthorectified images an orthophoto was created. Lastly, 3D features were collected in Stereo Analyst.
