To find the relative position of single UAV images to each
other the component RouteComputer was developed. This
component is based on image data and GPS data provided by
the PAMS software for each UAV image. For visual control for
the operator an image and a video is produced to show the
structure of the block, as well as the whole block structure is
stored for the final matching in the whole block. The
RouteComputer is able to distinguish between a drift caused by
wind or a real change of image strip. This is very important, as
the flight direction change requires the images to be rotated by
180° for a consistent image block.
