Dr. Jaewoo Jung published his research work on 3D building modelling methods in the ISPRS Journal (doi.org/10.1016/j.isprsjprs.2019.01.003). This journal suggests an innovative method for automatically updating an existing 3D rooftop model by aligning temporal imagery. This progressive modelling pipeline is developed based on Markov Chain Monte Carlo coupled with simulated annealing. The performance evaluation conducted with the ISPRS benchmark data proves the potential of our progressive modelling approach as an effective tool for updating large-scale city models.
