Embodiment 1

[0113] Taking the image taken by the photoelectric reconnaissance payload of the UAV as an example, first, based on the pruned and compressed lightweight target detection model, the data processing of the reconnaissance payload is realized in the airborne artificial intelligence chip, and the real-time detection of multiple types of targets is completed. , to obtain the target category and position information; then, according to the flight parameters of the drone and the photoelectric load parameters to locate the target, obtain the latitude and longitude of the target, and the drone will frame and forward the acquired target location and category information; After receiving the target information, other UAVs decide whether to conduct cooperative reconnaissance. If cooperative reconnaissance is required, other UAVs fly to the target area to conduct reconnaissance again, obtain the target information from the perspective of the UAV and forward it; finally, quote the comprehensi...

Abstract

The invention provides an unmanned aerial vehicle cluster cooperative reconnaissance method and system under the condition of limited communication bandwidth, relates to the technical field of target reconnaissance, and can solve the problems of limited communication bandwidth, large target detection delay and low precision in unmanned aerial vehicle cluster reconnaissance. The method comprises the following steps: S1, a first unmanned aerial vehicle collects a target picture and analyzes the target picture on an airborne end to obtain target information under a stand-alone view angle and share the target information in a cluster; the collected target information is sent to the comprehensive judgment module while the pictures are continuously collected; s2, other unmanned aerial vehicles respectively judge whether cooperative investigation is carried out or not, if cooperative investigation is carried out, picture collection is carried out on a target according to the received target information, airborne end analysis is carried out, target information under respective view angles is obtained, and meanwhile the obtained target information is sent to a comprehensive judgment module; and S3, the comprehensive judgment module analyzes the received target information to obtain a final investigation result. The technical scheme provided by the invention is suitable for a target investigation process.

Description

technical field [0001] The invention relates to the technical field of target reconnaissance, in particular to a method and system for collaborative reconnaissance of drone clusters under the condition of limited communication bandwidth. Background technique [0002] In the application of UAV reconnaissance, due to problems such as lack of target information and easy occlusion of the target in the process of stand-alone reconnaissance, the target cannot be searched quickly. Therefore, the cluster cooperative reconnaissance search can detect the target position faster information for quick search and rescue. At the same time, the communication bandwidth of the reconnaissance equipment will be limited to a certain extent. Automatic target recognition technology based on UAV cluster cooperative reconnaissance and edge hardware acceleration will become a research hotspot in the field of UAV multi-machine cooperative reconnaissance search and rescue. [0003] In the multi-aircr...
