Abstract
Orienting the photogrammetric imagery by means of existing control entities is one of practical issues which aim to automatically acquire the control information from the database and perform the photo measurements in an attempt to reduce the labor involvement, as well as to promote the working efficiency towards orientation solutions. The author investigates in this study the strategic algorithms where the exterior orientations of the aerial photographic imagery are solved by matching with control patches. The proposed working scheme features itself with the designed platform of the human-machine interface where the measurements of control patches on the imagery can be achieved by through manual, semi-automatic, or fully automatic mode. Furthermore, the disagreements of control patches against the imagery, usually the phenomena of the scene change, are able to be identified and fed back to the system. The experiments show that the positioning quality of oriented imagery performed under the proposed scheme can reach up to sub-pixels and one to two pixels in horizontal and vertical components, respectively, a satisfaction towards orienting the imagery.
