【摘要】:光學(xué)遙感衛(wèi)星影像在軌幾何定標(biāo)是確保影像幾何質(zhì)量的必要環(huán)節(jié)。首先介紹了光學(xué)衛(wèi)星在軌幾何定標(biāo)方法的研究現(xiàn)狀;然后,對于當(dāng)前主流的基于地面幾何檢校場的在軌幾何定標(biāo)方法,結(jié)合光學(xué)衛(wèi)星地面分辨率不斷提高的發(fā)展趨勢,闡述了其受限于對參考影像的依賴而存在的問題;最后,論述了無需地面定標(biāo)場的在軌自主幾何定標(biāo)的發(fā)展趨勢,并提出了多種基于多角度交叉約束成像的在軌自主幾何定標(biāo)方法構(gòu)想。
[Abstract]:In-orbit geometric calibration of optical remote sensing satellite images is a necessary step to ensure the geometric quality of images. This paper first introduces the research status of the on-orbit geometric calibration of optical satellites, and then, for the current mainstream geometric calibration methods based on the ground geometric calibration field, combined with the development trend of improving the ground resolution of optical satellites. The problems existing in the dependence on reference images are explained, and the development trend of orbital autonomous geometric calibration without ground calibration field is discussed. Several on-orbit autonomous geometric calibration methods based on multi-angle cross-constraint imaging are proposed.
