Problems solved by technology

[0002] At present, some colleges and universities have large campuses, or there are multiple adjacent campuses, and the logistics of small items are mostly carried out by special personnel, which has high labor costs and low efficiency.
[0003] Most of the flight routes of UAVs in the prior art are completed through real-time control, and very few parts are carried out through automatic identification. However, for short-distance transportation, real-time control requires a special person to be responsible for the control, and the labor cost is too high. Automatic identification means that the corresponding equipment costs are relatively high, and as far as the current development of automatic identification technology is concerned, to achieve sufficient accuracy, its cost is far from acceptable for general colleges and universities in daily object transportation applications

Embodiment Construction

[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0019] The invention provides a method for planning a flight route of a short-distance transport unmanned aerial vehicle, comprising the following steps:

[0020] ①Read model: read the map with building height data from the map database;

[0021] ② Determining the height: Calculate the average value from the building height data;

[0022] ③Intercept contour surface: In the map data, the calculated average value is taken as the intercept height, and the corresponding plane map is intercepted;

[0023] ④ Curved connection line: For the connection line between the starting point and the end point on the plan, take a point as the bending point at the part where the connection line passes through the building coverage, and use the bending point to bend the connection line so that the connection line does not pass through any building ...

Abstract

The invention provides a method for planning a flight route of a short-distance transportation unmanned aerial vehicle, and the method comprises the following steps: 1, reading a model, to be more specific, reading a map with building height data from a map database; 2, determining a height, to be more specific, calculating the average value of the building height data; 3, intercepting a constant-height surface, to be more specific, intercepting a corresponding plane graph from map data by use of the calculated average value as an interception height; 4, bending a connection line, to be more specific, taking a point on one part, passing through a building cover surface, of the connection line between a starting point and a terminal point as a bending point to bend the connection line and enable the connection line not to pass through any building cover surface; 5, optimizing a path, to be more specific, the height of the obtained connection line is increased by 3 to 10%, two ends of the connection line are connected with the connection line are connected with the starting point and the terminal point, and curve smoothing treatment is performed on the two ends of the connection line; and 6, sending the path. According to the method, the flight path planning problem of the short-distance transportation unmanned aerial vehicle can be effectively solved by a process with an extremely small amount of calculation in a very low cost manner.
