Embodiment
[0039] The present invention will be further described in detail below in conjunction with the drawings.
[0040] A global navigation assistance method based on UAV shooting and semantic segmentation, such as figure 1 As shown, the package sets the target flight area of the UAV, and uses the Dubins trajectory planning algorithm to plan the flight cruise trajectory;
[0041] The drone shoots the target flight area according to the set flight cruise trajectory. The drone shoots the ground at an angle perpendicular to the ground, and evenly selects a series of points in the straight flight path in the cruise trajectory as GPS position calibration points. Used for subsequent position correction;
[0042] After the drone returns home, upload the information in the memory card it carries to the server to obtain the drone shooting data. According to the GPS point information and time stamp information carried by each photo in the shooting data, the photos can be known The position corre...
