[0027] Hereinafter, the present invention will be described in detail through the drawings.
[0028] Such as figure 1 Shown is the flow of the image processing method for the centimeter-level accurate landing of the drone of the present invention.
[0029] Such as figure 2 As shown, there are four rectangles, namely the large rectangle 1, the first small rectangle 21, the second small rectangle 22, the third small rectangle 23, and the two-dimensional code 3. The target recognition pattern is a large large rectangle and three small rectangles. And a single two-dimensional code, the center of the large rectangle, the center of the three small rectangles, and the center of the two-dimensional code overlap; the color of the large rectangle and the small rectangle are different. In the present invention, the large rectangle is red, and the three small rectangles are green. The color of the red rectangle and the green rectangle is not unique, and the RGB difference between the two is ...
