摘要：Nowadays, Open Skies uses mainly whiskbroom type thermal scanners, which provide images in the 3-5μm and 8-12μm ranges. This way of acquiring images introduces commonly known geometrical errors. They result from the .philosophy" of the scanner performance and from the flight parameters. Determination of geometrical errors sources is particularly important for certifying scanners mounted on aircraft. The paper presents a method of determining geometrical errors impacting the quality of images by means of application of calibration targets deployed in the scanned region. The developed method enables to determine both the flight parameters and scanner performance parameters using the acquired images of the target. Computer software developed according to the method enables to determine the basic characteristics of the test flights and hence to eliminate flights that do not comply guidelines
