HJ-1-A/B optical satellite image geometric correction

Small satellite constellation of environment and disaster’s monitoring and predicting (shorted for HJ-1) is not a mapping satellite, and its parameters of attitude and orbit cannot satisfy the requirement of geometric correction using strict imaging model. On the other hand, due to the 12000 CCD detectors and large overlay of multispectral payload named CCD carried by HJ-1 satellite, the error ...

Automatic Precise Geometric Correction for Hj-ccd Imagery

Since HuanJing(HJ)-satellite has been sent successfully in September 6, 2008, in china, productions of precise geometric correction are imminently needed. Moreover, the demand for rapid processing of remote sensing data for disaster is increasing. Aiming at the characteristics of HJ-CCD imagery, a precise geometric correction technology workflow has been designed, which is a very meaningful wor...

Case study of atmospheric correction on CCD data of HJ-1 satellite based on 6S model

In this study, atmospheric radiative transfer model 6S was used to simulate the radioactive transfer process in the surface-atmosphere-sensor. An algorithm based on the look-up table (LUT) founded by 6S model was used to correct(HJ-1)CCD image pixel by pixel. Then, the effect of atmospheric correction on CCD data of HJ-1 satellite was analyzed in terms of the spectral curves and evaluated again...

A model-based approach for geometric correction of optical satellite images

Sammendrag/Abstract: In this report, we describe a method for geometric correction of satellite images generalizing a method developed for NOAA AVHRR images. The method is based on modeling the imaging process, including satellite orbital modeling. We also present an approach for automatic detection of ground control points based on matching of a near-infrared band with watermasks. The methods ...

Geometric distortion correction in image watermarking

In this paper we report a novel method to estimate the scaling factor of a previously scaled watermarked image and the angle by which the image has been rotated. Scaling and rotation performed on a watermarked image, as part of the attacks the image may undergo, can very easily confuse the decoder unless it rescales and/or rotates the image back to its original size/orientation, i.e., recover t...
