Abstract

The invention discloses a low-altitude target tracking information fusion method and system based on a multi-source detector. The method comprises the steps of enabling each detection station device to detect and measure the distance of an obtained image of a target appearing in a view field; obtaining position information of a target relative to each detection station device and feature information of the target; each detection station device uploads detected target position information and target feature information to an information fusion system, and the information fusion system determines a target geocentric coordinate system coordinate according to the target position information uploaded by each detection station device; fusion matching of time data and space data is carried out onthe target position information and the feature information uploaded by each detection station device; and the state information of the target is detected according to the fusion matching result. Themeasurement target information of the active detection station and the passive detection station is fused to realize advantage complementation, and the target accurate position information and the target type are obtained through information fusion calculation.

Description

technical field [0001] The invention relates to the technical field of target imaging information fusion, in particular to a multi-source detector-based low-altitude target tracking information fusion method and system. Background technique [0002] In recent years, drones have been appearing in people's sights. In addition to being widely used in the military, UAVs are also rapidly expanding in the civilian market. Civilian drones are not only widely used in aerial photography, but also in fields such as agriculture, forestry and plant protection, security law enforcement, environmental protection research, mineral resource exploration, disaster emergency rescue, oil pipeline inspection, border defense, and maritime patrol. According to incomplete statistics, there are hundreds of thousands of consumer-grade drones in China at present, showing a doubling growth trend every year. The rapid popularity of drones is bringing unprecedented challenges to the security work of var...
