Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] A layout method for a local map network for unmanned aerial vehicles, as attached figure 1 As shown, the dotted line box indicates that the area is the target plot, and several annunciators 1 are arranged in the target plot. The control terminal 2 takes its own position as the origin, collects the signal sent by the annunciator 1 and calculates the relative space of each annunciator 1 location, and then the location data is stored as a local map; the control terminal 2 communicates with the flight control system of the drone, and relies on the local map to guide the drone to perform flight operations; the control terminal 2 has communication functions and data Processing calculation function, this kind of positioning method can specifically be realized by radio, that is, the control terminal 2 is used as the origin of determining the position, the radio signal s...

The invention discloses an arrangement method of a local area map network for an unmanned aerial vehicle. A plurality of annunciators are arranged in a target plot, the position of a control terminalis taken as an original point, signals sent by the annunciators are collected, relative spatial positions of all the annunciators are calculated, and then the position data is stored as a local area map; the control terminal is in communication connection with a flight control system of the unmanned aerial vehicle, and the local area map is used for guiding the unmanned aerial vehicle to carry outflight operation. The positioning method does not depend on a satellite positioning system such as a GPS, and cost for using a base station and purchasing a mobile base station is saved; and meanwhile, the local area map can overcome the error of the GPS in the altitude height direction, accurate judgment on the terrain in the plot is realized, so that the flight safety and the operation accuracyof the unmanned aerial vehicle are improved.
Description
technical field [0001] The invention relates to a method for arranging a local map network of an unmanned aerial vehicle. Background technique [0002] With the development of science and technology, drones have begun to be used in many fields such as pesticide spraying, forest fire monitoring, and geological exploration. The accuracy of positioning and navigation determines the precision of UAV aerial operations. Because the error of direct GPS navigation is large, the existing UAV navigation usually adopts two methods: network RTK and base station RTK, and uses satellite differential positioning to achieve high positioning accuracy. However, to use network RTK, a corresponding network card is required, which is expensive to use, and the cost of flight operations is high; while using base station RTK uses mobile base stations for auxiliary positioning, and the cost of equipment procurement and use is also high. Therefore, it is necessary to invent a method for arranging a...
