Parliament survey and 3D modeling

We created two versions of the 3D model of the building, the first one can be seen above. A small model was made by processing 750 distant photos. This could show the georefenced model of the building with up-to 10 cm precision. The second complete set consisted of 10000 pictures. 


This is a 5-step process, the hardest of which is the stitching of the images and finding their place in space. The program recognizes typical patterns and pairs images to put them into space.

Dense mesh

Here we get the model's quality and details.

Creating the mesh/surface

We create a surface from millions of points - 77 million to be exact - using small triangles. 


We apply textures to the model's surfaces from perpendicular shots of the building.



The fully-detailed model consists of 1 billion polygons, so we only showcase a few examples here.

Northeast tabernacle

Every part of the model can be precisely measured - depending on the detailing - all the way to 1cm precision.

Roof model


Our technique can be adapted to survey indoor environments or to create segments.
