中文说明：
飞机上带有北斗导航或者GPS等定位装置，能够实时确定飞机的空间位置，获得其高度，经纬度等信息；飞机上载有光电吊舱，能够从高空拍摄图像或视频，并且能够通过其自带的传感器实时获得光电吊舱自身的倾斜角度、视场角度等信息；结合飞机所处的空间位置，光电吊舱的倾斜角度、视场角度以及地理信息系统就可以计算出光电吊舱所看到的区域所在的地理位置，并在地理信息系统中显示出其区域；若对图像中的某一局部区域感兴趣，需要确定其地理位置，则可通过鼠标点击这一区域，程序就能主动地计算出目标地点的地域坐标，并映射到地理信息系统中，将其标注出来。
English Description：
The aircraft is equipped with positioning devices such as Beidou navigation or GPS, which can determine the spatial position of the aircraft in real time, obtain its altitude, longitude and latitude and other information; the aircraft is equipped with photoelectric pod, which can take images or videos from high altitude, and obtain the tilt angle, field of view and other information of the photoelectric pod itself in real time through its own sensors; combined with the spatial position of the aircraft If you are interested in a local area in the image and need to determine its geographical location, you can click the area with the mouse, and the program can calculate the target location actively The geographic coordinates of the points are mapped to the geographic information system and marked out.
