However if you have a large number of images (several hundrets or more than thousand) and control points, PTOptimizer typically needs much time (up to several days) for the optimization of the parameters.
fastPTOptimizer decreases the processing time for large panoramas (a speedup factor of 100 or more can be achieved). ...
