A generalized imaging system geometric model has been incorporated into the Center for Imaging Science Digital Imaging and Remote Sensing Image Generation (DIRSIG) software system. The camera model is capable of simulating the geometric characteristics of frame cameras, line scanners and pushbroom scanners. The user of the model has the ability to define both the sensor internal orientation as well as provide time varying external orientation parameters. The model has been successfully validated through the use of both diagnostic simulated scenes as well as quantitative comparisons between actual imagery and simulated imagery.
