摘要
中国海监飞机担负着维护海洋权益,保护海洋环境和资源,以及监视海洋自然灾害等诸多职能。在这个飞机上,安装着由中科院上海物理技术研究所研制的一种新型海洋多光谱遥感器(MAMS)。由于海监飞机执法的突发性,靠获得完备信息的传统校正方法很难胜任。本文针对海监飞机执法的这一特点,在仅仅具有GPS——安装在MAMS上的全球定位系统——数据的情况下,进行了几何校正的方法研究。首先,本文利用GPS中的经纬度和海拔高度信息,反演出姿态值,完成初步校正,然后再由飞行航线得到一个修正因子,最后,利用这个修正因子对初步校正的结果进行了修正,取得了比较满意的效果。
China marine surveillance plane undertakes the function of coastal area monitoring for ocean safeguarding, environment and resources protection and national disasters detection, etc. One of the onboard equipments is marine airborne multi-spectrum scanner (MAMS) developed by Shanghai institute of technical physics, CAS. Because the function of the marine surveillance planeis is unexpected, traditional methods of geometric correctionby gaining enough information can not work. In this paper , based on the reason above, a new method of geometric correctiononly using the onboard GPS date is discussed. Firstly, fight attitudes are computed by the latitude, longitude and altitude date, then the rough geometric correction is completed! Secondly, the correctional parameters is calculated according to the flight course; Finally, the rough result is corrected by correctional parameters, which is satisfied.
