摘　　要：为了解决无人机的全天候自主着陆，从所设计的合作目标自身的形状特征出发，提出了通过目标轮廓的方向链码快速实现目标的长宽比进而识别出目标的一种新的方法，并通过目标的形状特征确定无人机自主着陆的方向；实验表明，该方法较好地实现了合作目标的快速识别。For salving UAV＇s automatic landing in ＇all weather, a new algorithm using the direction code of the cooperative target＇s contour is brought forward to achieve the target＇s fast recognition based on the target＇s own features. In the algorithm, the cooperative target is recognized by the ratio value of the target＇s direction code of two lengths. On the basis of the target＇s figure, the landing spot and the direction of UAV＇s automatic landing is ascertained. Experiments show that the algorithm better completes the fast recognition of the cooperative target.
