A method for analyzing the detection range of unmanned aerial vehicles

Abstract

The invention discloses an analysis method of an unmanned aerial vehicle detection range. The analysis method comprises the following steps: S1: dividing a target region into grids, and calculating the area of a three-dimensional terrain corresponding to each grid; S2: constructing a virtual camera view frustum, carrying out intersection calculation on the virtual camera view frustum and the three-dimensional terrain through GPU (Graphics Processing Unit) automatic cutting, calculating the detection range of an unmanned aerial vehicle wave beam, obtaining a practical region area detected by the one-time wave beam scanning of the unmanned aerial vehicle, and meanwhile, recording the irradiation duration and distance of all grids in a boundary line; and S3: in a whole detection process, carrying out statistics on the practical region area detected by each-time scanning wave, and the irradiation duration and distance of all grids in the boundary line, and carrying out coloring on the grids according to the irradiation area, duration and distance of the grids. By use of the analysis method of an unmanned aerial vehicle detection range, the detected terrain is preprocessed, the detection range can be quickly calculated through hardware cutting, detection information is displayed through a color temperature map, an amount of information is large, and an effect is visual.

Description

Technical field [0001] The invention relates to the technical field of drone terrain detection, in particular to a method for analyzing the detection range of the drone. Background technique [0002] With the rapid development of UAV (Unmanned aerial vehicle) technology, UAVs are playing an increasingly important role in military and civilian fields, such as aviation search and rescue, terrain analysis, high-altitude photography, and traffic diversion. Due to the remote control command, high flight altitude, and fast flight speed of UAV, its actual flight effect is difficult to be directly visualized by human eyes or other means. In order to better display the various data of the drone in the process of executing the mission, the detection data is often displayed in a graphical way. The coverage map visually describes the sensor's detection data of the hot spot area, which mainly includes the area traversed during the mission, the residence time of each sensor area, and the vert...
