Photogrammetry Demo

Using Photogrammetry To Create 3-D As-built CAD Models

Site mobilisation: High resolution calibrated digital camera Reflectorless total station Self adhesive survey targets 2 man team

A control network is placed in prominent locations This enables the total station to be moved anywhere within the scope The working position is then calculated by the total station Targets for the local photogrammetry survey can now be placed

Pairs of overlapping photographs are taken.

This process is repeated for the entire scope of work.
