The invention discloses a method for extracting the height of a vertical ground object on an aerial area array CCD remote sensing image, and a strict imaging geometrical relationship model of the aerial area array CCD remote sensing image is applied. The vertex image coordinates and the bottom point image coordinates of the upright ground object are calculated according to the coordinate transformation coefficient and the projection proportionality coefficient which are calculated according to the attitude of the aircraft to obtain the height of the upright ground object, other features of the upright ground object do not need to be extracted, and data of two images do not need to be adopted either. Therefore, the method can simplify the process of extracting the height information of various upright ground objects on the aerial area array CCD remote sensing image. 本发明公开了一种航空面阵CCD遥感图像上直立地物高度的提取方法，应用了航空面阵CCD遥感图像的严密成像几何关系模型，通过根据飞机的姿态计算得到的坐标变换系数和投影比例系数对直立地物的顶点图像坐标和底点图像坐标进行计算得到直立地物的高度，无需提取直立地物的其它特征，也不需要采用两幅图像数据，因
