The invention mainly solves the problem of how to meet the requirement of aerial hyperspectral imaging exposure time and reduce image motion at the same time. A method for reducing aerial hyperspectral imaging image motion is characterized by comprising the following steps that a, n hyperspectral imagers are longitudinally arranged and installed below an aircraft, n is larger than or equal to 2, and the arrangement direction is parallel to the front-back direction of the aircraft; b, setting the exposure time of the n hyperspectral imagers to be 1/n of a standard value; c, during each aerial photography, the aircraft controls the shooting time of the hyperspectral imagers, shooting is carried out from front to back according to a certain time interval, and it is guaranteed that all the hyperspectral imagers shoot the same ground area. The method has the beneficial effects that the specification parameters of the n hyperspectral imagers are the same, so that the exposure time of the n hyperspectral imagers can be superposed equivalently, the exposure time of a single hyperspectral imager is reduced to 1/n of the current exposure time, the exposure time is obviously reduced, and the image motion is reduced.
本发明主要解决的问题是,如何满足航拍高光谱成像曝光时间同时减少像移。一种减少航拍高光谱成像像移的方法,其特征为,包括如下步骤:a.将n个高光谱成像仪纵向排列并安装在飞行器的下方,所述n≥2,所述排列方向与飞行器的前后方向平行;b.将所述n个高光谱成像仪的曝光时间均设置为标准值的1/n;c.每次航拍时,所述飞行器控制所述高光谱成像仪的拍摄时间,按照一定的时间间隔从前到后先后拍摄,保证各高光谱成像仪拍摄的是同一片地面区域。有益效果是,由于所述n个高光谱成像仪的规格参数相同,因此,其曝光时间相当于是可以叠加的,将单个高光谱成像仪曝光时间减少到目前的1/n,显著减少了曝光时间,减少了像移。
