Panoramic cameras, which seek to combine high resolution and wide swath in one camera, have been used extensively for different photographic interpretation purposes. The main aim of this research has been to use panoramic linear array scanner data for the purpose of photogrammetric measurements. The collinearity equations are extended to accommodate the panoramic linear array sensor. The research also tries to address the problem of integration of different sensors: frame cameras, panoramic sensors and three line scanners with GPS/INS support. The mathematical and physical models are discussed. Moreover, software capable of a combined calibration and integration of different sensors has been developed by an extended bundle adjustment. After a short review of the mathematical model, the computational scheme for an extended bundle adjustment is provided. Finally the results for a series of simulated and real test field data for each of the sensors and an analysis of the accuracy obtained are discussed. Some concluding remarks and ideas for future development are also suggested.
