Method and device for determining collision risk of unmanned aerial vehicle

[0063] Embodiment 1: Determine whether the target UAV has a collision risk according to the target stereo code composed of the target geographic code and the altitude code.

[0064] see Figure 5 , Figure 5 It is a schematic diagram of target stereo encoding in the embodiment of this application. That is to say, in the flying airspace, the target UAV is located in Figure 5 The spatial region corresponding to the target stereo code wtmk4rbp001110 is shown.

[0065] see image 3 , image 3 It is a flow chart of determining whether the target UAV has a collision risk according to the target stereo code composed of the target geographic code and the altitude code provided by the embodiment of the present application. Such as image 3 As shown, the embodiment of the present application provides a target stereo code composed of a target geographic code and an altitude code to determine whether the target UAV has a collision risk, including the following steps:

[0066] S10311.

[0072] Embodiment 2: According to the geographic code of the target, it is determined whether the target UAV has a collision risk.

[0073] see Figure 4 , Figure 4 It is a flow chart of determining whether a target UAV has a collision risk according to the target geocode provided by the embodiment of the present application. Such as Figure 4 As shown, the determination of whether the target UAV has a collision risk according to the target geocoding provided by the embodiment of the present application includes the following steps:

[0074] S10321. Obtain geocodes adjacent to the target geocode.

[0075] Wherein, the geocodes adjacent to the target geocode refer to the geocodes of the grids adjacent to the grid corresponding to the target geocode.

[0076] The adjacent geocoding in the embodiment of the present application refers to creating a nine-square grid with the target geocode as the center, and the remaining eight geocodes of the nine-square grid except the central
