摘要:This paper outlines the results of an analysis of the application of LIDAR technology for orthorectification of QuickBird images without using ground control points for the area of the city of Ottawa in Canada as well as for boreal forest areas in the province of Alberta. Geometrical adjustment of QuickBird images was executed using the RPF multinomial method with the use of RPC and the application of the co-linearity condition method. The effects of adjustment models are described in the paper. In order to evaluate the accuracy of the ortho-photo map generation process,both DCM and DSM obtained from laser scanning data were used. The PCI Ortho Engine environment was used as a tool for ortho-adjustment and the evaluation of accuracy. Errors obtained in the ortho-adjustment process were of the order of 2-3 pixels for municipal areas and 1 pixel for forest areas. The influence of a number of ground control points upon the accuracy of ortho-adjustment process was also investigated. The accuracy of the final satellite ortho-photo map was evaluated by applying GSP surveys. The obtained results show the importance of data coming from different Earth monitoring sources,which are used more and more extensively in a variety of different geometric applications. Since VHRR and LIDAR became operational there has been increasing consumer demand for both elevation models and images. As all data is digital from the beginning,data processing is done relatively quickly and is highly automated (mainly only quality control needs operator support),it was demonstrated in practice that the data from laser scanning may constitute an excellent source of photogrammetrical control for the adjustment of very high resolution satellite images. The spectrum of application for precise elevation data and orthophotomaps is much greater than shown here and includes such applications as power line mapping,precision forest management,and open-pit monitoring.
