GPS-SUPPORTED DETERMINATION OF INTERIOR ORIENTATION ELEMENTS OF AERIAL CAMERA Yuan Xiuxiao School of Remote Seneing and Informatics Wuhan Technical University of Surveying and Mapping 39 Luoyu Road, Wuhan, 430070, P.R. of China Commission |, Working Group 3 KEY WORDS: Accuracy, GPS, Method, Aerial Camera, GPS-supported Single-image Resection, GPS- supported Bundle Adjustment. ABSTRACT It is common knowledge that we can solve the elements of interior orientation X,,y,,f of aerial camera in collinearity equation with enough ground control points. However, in the case of vertical photography, the solution of the normal equation may be faced with singularities because x,,y,,f and Xs, Y.,Z. offset each other. Therefore, the conventional aerotriangulation solves only the elements of exterior orientation q,o,x, Xs, Y s,Zs of photograph, whereas the elements of interior orientation x;,y,,f of aerial camera are often determined in the laboratory. As the laboratory methods can not take into full account the actual conditions in aerophotography, large deviations often occur. This paper raises two kinds of GPS-supported determination methods for the elements of interior orientation of aerial camera for the first time. The basic formula are derived form GPS-supported single-image resection in space and GPS-supported bundle block adjustment. A set of actual determination results obtained by camera Wild RC-20 with GPS data from the test field in Taiyuan are given and discussed. The test has confirmed that the two presented methods are correct in theory and efficient in practice. If several pictures with carrier phase measurements are taken over a high precision test field before and after an air photographic mission, the elements of interior orientation of aerial camera can be determined by using GPS- supported single-image resection in space. The determination method of interior orientation elements in GPS-supported bundle block adjustment does not pose any major problem for photogrammetric adjustment but can efficiently correct the systematic errors caused by the high dynamic aerophotography. To summarize the investigations in this paper can obtain that the dynamic determination methods for the elements of interior orientation will eventually replace the conventional photogrammetric operation method where the camera calibration is independent of photo orientation, and revolutionary changes will take place in the conventional aerotriangulation which had lasted 60 years and more. coordinate system.
