Abstract
Mobile phones with cameras enable us to take photos of any objects at any
time. The question arises whether this new device of communication can play
a role in obtaining geometric data and what accuracy demands can still be
satisfied by this device.
Our series of experiments essentially involve taking photos of a
geometrically defined area and examining the degree of likelyhood of the
photogrammetric solution to the known geometry. This study was extended to
various cameras, the number of points with known co-ordinates, the number of
shots, and the object distance which has a decisive impact on picture scale.
Furthermore, we compared the accuracy values of the results yielded by the
processing of images taken by mobile phones with cameras and by other
cameras.
Numerical results are disclosed in a tabular format and the conclusions to
be drawn from the numbers are summarized
