Puerta de Toledo Photogrammetric Reconstruction

Some months ago, the Ciudad Real city council performed some maintenance and repair works on the Puerta the Toledo gate, one of the most iconic constructions in the city. This medieval construction was built in the 13th century, under the reign of Alfonso X.

During the Christmas break, I had the opportunity of have a walk around it and taking advantage of the solitude of New Year’s day, I took some pictures with my cellphone from the ground.

After processing the images with Agisoft Photoscan and cleaning the dense point cloud by means of CloudCompare,  here you are some results. That was a sunny and clear day and I took the pictures in the afternoon, so there is an important difference between the north face (top left) and the south one (top right). Where are the clouds when one needs them?
