Abstract

A uav-based system equiped with a non-metric camera for low altitude photogrammetric applications was introduced in this paper. The system is very inexpensive since it utilizes readily available unmanned airplane and common non-metric digital cameras. Aim of the paper is to give solutions to problems derived from the image processing. In the first step,the camera parameters of inner orientation and geometric distortions were solved by means of self-calibrating bundle adjustment with own developed software and the non-metric camera was evaluated. The second part concerntrates on the aerial triangulation process to deal with high redundant images acquired with the uav-based system. Finally, the utility of the system for photogrammetric applications was demonstrated with a test flight in China.
