英文摘要 | Pushbroom-style imaging systems are widely used in the high-resolution optical remote sensing. This style will lead to streaking and banding, because of inter-detector sensitivity differences, factors related to image formation. There are many traditional methods that are used to eliminate pixel-to-pixel uniformities, such as on-orbit calibration device, "Flat field" calibration and imaging statistical method with lots of images. This paper proposes an improved side-slither maneuver based on moment matching for on-orbit calibration of high-resolution satellite imagery. The disadvantage of the side-slither method is that the images captured with the sensor in a 90 degrees orbit configuration must include uniformity sites such as desert and snow/ice regions. The improved method does not have the requirement that the content of the images for calibration must be uniformity sites. With a linear normalization model, a relative gain can be calculated using the moment matching method to adjust the side-slither maneuver. The approach is characterized by its reliability which is based on the purely statistical analysis of images without any sites constraint. And some indicators are used to assess the normalization residuals after the relative radiometric correction. It is noted that the accurate geometric registration of the successive line of sight projection is necessary and the total amount of pixels should be high enough to achieve a good precision. |
