Abstract

The invention provides a low-altitude flight target identification system based on a three-dimensional digital earth. The system comprises a digital earth related unit, an AI processes the related unit and a target related unit, which are mutually connected; A graphic algorithm and a spatial data model analysis algorithm based on a three-dimensional digital earth technology are used; A new artificial intelligence discrimination algorithm is formed, a large number of low-altitude flight targets can be rapidly identified at the same time, and the hazard levels of the large number of targets canbe intelligently predicted in real time according to a preset management strategy, so that the safety supervision capability of the low-altitude security and protection system on low and small slow flight objects is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of low-altitude security, and in particular relates to a low-altitude flight target recognition system and algorithm based on a three-dimensional digital earth. Background technique [0002] In the field of low-altitude security, for the identification of UAVs and similar low-flying targets of UAVs, radio positioning equipment, microwave radar equipment, etc. are usually used for target direction and distance discrimination, and photoelectric imaging equipment is used to assist in target type identification. judge. In the current low-altitude flying object monitoring system, GIS geographic information system is also commonly used to display the position of flying targets and control area monitoring and other management functions. These implementation methods usually can only achieve effective identification and monitoring of a single flight target, and cannot quickly identify a large number of targets at th...
