Embodiment Construction
[0034] The present invention will be described in detail below by means of the accompanying drawings.
[0035] Such as figure 1 As shown, it is a flow chart of the flight control method for the precise landing of the drone of the present invention.
[0036] Step 1: Make target recognition graphics and place them at the target landing point; figure 2As shown, the target recognition pattern is composed of a large rectangle 1 and three small rectangles, which are respectively the first small rectangle 21, the second small rectangle 22 and the third small rectangle 23, and a single two-dimensional code 3, so The center of the large rectangle, the center of the three small rectangles, and the center of the two-dimensional code coincide; the colors of the large rectangle and the small rectangle are different, and the RGB difference between the two is large.
[0037] Among the present invention, the color of the large rectangle is selected red, and the color of the small rectangle...
