Abstract

Since 1975 lateral-effect photodiodes have been well-known opto-electronic sensors for the measurement of imaged light sources. They provide a simple evaluation of the image coordinates of the centroid of an imaged light source and have excellent dynamic characteristics. Due to the physical principle of these sensors the accuracy of 3D-measurement is greatly influenced by reflections and distortion causing large non-linearities. This paper describes investigations concernig the theoretical and experimental accuracy behaviour of a developed photogrammetric system equipped with lateral-effect photodiodes.
