Abstract:In order to provide the model point accuracy of ±2 mm, an extra high accuracy industrial control net with four surveying piers with accuracy ±0.1 mm was set up around the model. Tens of orientation marks have been placed on the different parts and measured with accuracy ±0.2 mm from the above-mentioned piers. The main four stereopairs taken with the P31 camera around the model are simultaneously processed on the BC2 analytical plotter. The accuracy of absolute orientation is better than ±0.9 mm. Finally, about 300 sections construction drawings have been directly offered, and the closerange photogrammetric data has been used for the design and construction of the statue.
Keywords:close-range photogrammetry  Kwan-yin Statue  construction drawing  industrial control net  high accuracy
