摘要：In recent years, digital aerial frame cameras got more and more attention in photogrammetry. A good example is the UltraCamX, which was introduced by Vexcel Imaging in Graz/Austria in 2006. This camera is able of taking a large sequence, multi-spectral (PAN, R/G/B/NIR), high resolution (132 mega pixel) images with high radiometric resolution. Aerial projects of the dimension of 3,000 multi-spectral images require over 1,2 tera byte disk storage and include over 480,000 mega pixel image data.One can imagine that handling this vast amount of images is getting a problem in the office. After each step of processing, the operator requires an in- depth quality control to ensure that all processed data fulfil the required quality expectations. At best, this is done not on an image- by-image manner, but should be done within the whole image block. This paper presents a new methodology for working with large blocks of high resolution aerial images produced by the UltraCamX. Our approach eases the handling of this large amount of data by using cutting edge technologies. In addition, we present an aerial triangulation application which is based on this visualization technique for fast image interaction
