本发明涉及基于地基光电设备的全自动飞机进近降落过程监视方法,属于飞机领域。该方法包括:开启降落飞机搜索流程,利用地基长焦复合光电探测设备监视机场跑道飞机进近着陆区域,进行旋涡型漫游搜索;利用地基光电探测设备不断采集图像Ik,其中k为视频帧数编号;对Ik进行自适应阈值的边缘特征提取得到边缘特征图Ek;再对Ik进行全局色度提取并求取均值,基于均值确立检测门限得到色度特征图Ck;将Ek与Ck融合得到特征图Fk,对Fk进行形态学滤波并进行连通域分析得到最大似然目标外接矩形;基于外接矩形高、宽度通过图像高、宽度比值归一化,基于归一化后的高、宽度占比调节视场大小;重复上述步骤,开启下一个轮次的程序处理循环。

    The invention relates to a full-automatic aircraft approach landing process monitoring method based on foundation optoelectronic equipment, and belongs to the field of aircrafts. The method comprises the following steps: starting a landing aircraft search process, monitoring an airport runway aircraft approaching a landing area by utilizing foundation long-focus composite photoelectric detection equipment, and carrying out vortex type roaming search; continuously acquiring images Ik by using foundation photoelectric detection equipment, wherein k is a video frame number; carrying out self-adaptive threshold edge feature extraction on the Ik to obtain an edge feature graph Ek; performing global chromaticity extraction on the Ik, calculating a mean value, and determining a detection threshold based on the mean value to obtain a chromaticity feature map Ck; fusing the Ek and the Ck to obtain a feature map Fk, performing morphological filtering on the Fk, and performing connected domain analysis to obtain a maximum likelihood target bounding rectangle; normalizing the ratio of the height to the width of the image based on the height and the width of the bounding rectangle, and adjusting the size of the view field based on the normalized ratio of the height and the width; and repeating the steps, and starting the program processing cycle of the next round.
