大小二维码混合图像地标设计方法与无人机识别地标方法
摘要：
本发明公开了一种大小二维码混合图像地标设计方法与无人机识别地标方法，大小二维码混合图像地标设计方法包括：创建组成地标的大型二维码单元、小型二维码单元，所述大型二维码单元、小型二维码单元均有且仅有一个边角为白色子单元；设定地标尺寸，选择4个所述大型二维码单元、4个小型二维码单元用于构成地标图像；所述大型二维码单元、小型二维码单元以2 X 2矩形阵列方式排布；将所述大型二维码单元的白色子单元均设置于右下方边角；多个尺寸大小二维码配合使用，在更小的地标面积下，可以实现0.5米-5米的识别范围内较为准确的无人机识别定位，采用本方案直接解决了无人机整个着陆过程的定位过程的视觉信息丢失问题和地标过大问题。
摘要（英）：

The invention discloses a large and small two-dimensional code mixed image landmark design method and a UAV landmark identification method. The large and small two-dimensional code mixed image landmark design method comprises the following steps that large and small two-dimensional code units which form a landmark are created, and each of the two-dimensional code unit includes only one corner witha white subunit; the size of the landmark is set, and 4 large two-dimensional code units and 4 small two-dimensional code units are selected to form a landmark image; the large and small two-dimensional code units are arranged in a 2*2 rectangular array manner; and the white subunits of the large two-dimensional code units are arranged in the right lower corner. The large and small two-dimensional codes of different sizes are used cooperatively, so that a UAV can be identified and positioned more accurately in a smaller landmark area within the identification range of 0.5m-5m, and the problems of visual information loss and too large landmark during positioning in the whole UAV landing process can be solved directly.
