Photogrammetry

Posted on 1st July 2019

Wikipedia explains photogrammetry as 'the use of photography in surveying and mapping to ascertain measurements between objects'.

At Nexus Photography we use photogrammetry to construct 360° images from real-world objects or buildings. These images are then able to be viewed online and rotated through every angle, an ideal solution for roof inspections to determine missing or damaged tiles or loose and damaged chimney stacks. Traditionally inspections like these would have required scaffolding which is time consuming and costly.

Aerial platforms are used for buildings, lakes or large outdoor areas. For small sculptures or structures, ground based photography can be gathered using DSLR cameras coupled with GPS EXIF data.

A point cloud is generated from these photographs using software from which a mesh is constructed.

Texture and material information from the photographs is then mapped to the mesh and a final 360° object is created.

If you'd like to find out more about photogrammetry or discuss with us your requirements or how we can help then please feel free to get in touch. You can contact us by filling out the form HERE.
