The invention mainly solves the problem of how to ensure that the image is matched with each point on the ground when a plurality of hyperspectral imagers are involved in the hyperspectral imaging method for the aircraft. A hyperspectral imaging method for aerial photography is characterized by comprising the following steps that a, m hyperspectral imagers are arranged in a row and installed under an aircraft, m is larger than or equal to 2, and the hyperspectral imagers are responsible for imaging of different wave bands; and b, the straight line where the m hyperspectral imagers are located is perpendicular to the course of the aircraft, the distance between the m hyperspectral imagers is fixed, the m hyperspectral imagers shoot at the same time during aerial photography every time, and the ground area shot by the m hyperspectral imagers has a certain total offset. The method has the beneficial effects that after aerial photography imaging, the total offset on the images shot by the hyperspectral imagers is deleted, and the remaining crossed parts of the images correspond to the same ground area.
本发明主要解决的问题是,用于飞行器的高光谱成像方法涉及多个高光谱成像仪时,如何保证其成像与地面上的各个点是匹配的。一种用于航拍的高光谱成像方法,其特征为,包括如下步骤:a.将m个高光谱成像仪排成一列并安装在飞行器下,其中m≥2,所述各高光谱成像仪分别负责对不同的波段成像;b.所述m个高光谱成像仪所在直线与飞行器的航向垂直,所述m个高光谱成像仪之间的距离是一定的,每次航拍时,所述m个高光谱成像仪同时拍摄,所述m个高光谱成像仪拍摄的地面区域有一定的总偏移量。有益效果是,航拍成像后,删除各高光谱成像仪拍摄的图像上的所述总偏移量,剩下各图像均相交叉的部分,其对应的即是同一片地面区域。
