Processing of digital three-line imagery using a generalized model for combined point determination

After a brief review of the present state of processing of digital imagery, generated by an optoelectronic three-line camera, the mathematical model used is described in detail. Furthermore, the model is interpreted as a special case of generalized combined point determination which is able to process both image coordinates of frame cameras and linear-array imagery. Then the efficiency of the mathematical model is demonstrated by simulated examples for strip adjustment and block adjustment of three-line imagery. The simulations were performed as free adjustment, with control points and with a given digital terrain model as the only control information. Finally, future tasks for R&D in connection with the use of opto-electronic three-line cameras are mentioned.
