Analysis method of unmanned aerial vehicle detection range

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 unmanned aerial vehicle terrain detection, in particular to a detection range analysis method of an unmanned aerial vehicle. Background technique [0002] With the rapid development of UAV (Unmanned aerial vehicle) technology, drones are playing an increasingly important role in military and civilian fields, such as aerial search and rescue, terrain analysis, aerial photography, traffic guidance, etc. Due to the characteristics of remote control command, high flying altitude and fast flying speed of UAV, its actual flight effect is difficult to be directly visualized and observed by human eyes or other means. In order to better display the various data of the UAV during the mission, it is often used to display its detection data in a graphical way. The coverage map visually describes the detection data of the sensor on the hotspot area, mainly including the area traversed during the mission, the residenc...
