摘要：A new photogrammetric load chain has been developed for the ADS40 pushbroom sensor focusing on parallel computation and interactive image processing. It allows image correction and rectification at load time, useful as well for interactive work for the generation of image products. The performance needed to fulfill these goals has only come with the move to multicore general purpose computers and programmable graphics cards. A flexible framework is needed that encourages data parallel design. A programming model called "stream processing" has been the approach taken by many when developing parallel libraries. In this paper we explore the stream processing model and how it applies to an ADS40 work flow. We look at how the model will apply to both general purpose computers and programmable graphics cards
