Photogrammetric image rectification

Rectify photos with the help of photogrammetry. So you get a completely level view of one side of a building for example. So you can take the result for measurements of this building. You can export the result as picture or as DXF file. If you take a photo of a rectangle what you get is a trapezoid. The program will rectify the trapezoid so that it will be a rectangle again and the scale of the original object will be restored.
