INFRARED CHARTING STUDY.
Abstract
The report presents the results of a study directed toward the determination of the feasibility of charting from infrared line-scan imagery. The major areas investigated within the study are: (1) Geometry of single-strip and stereo line-scan imagery, (2) instrumental-analytic relative and absolute orientation, (3) the analytical stereoplotter, (4) flight parameters, (5) equipment and imaging process factors. It is geometrically feasible to extract spatial coordinate data from idealized stereo line-scan imagery. Practical feasibility depends on the output accuracy requirements and the degree to which the idealized imagery geometry can be realized. Fore-and-aft stereo is superior to parallel-pass stereo for charting purposes. Knowledge of and control of flight parameters and scanner orientation during imagery collection are essential--the tolerances being much smaller than those for conventional photograaphic charting missions. Equipment modifications and calibration will enhance the output accuracy. Completion of the geometric formulations, programming, testing, analysis of errors, and design of equipment modifications are areas requiring further study. (Author)
