Automatic tracking method of dynamic target based on image layer

Abstract

The invention relates to an image layer-based dynamic target automatic tracking method. The method includes: obtaining the numerical value of sonar information from the underwater equipment transducer, obtaining the original image matrix through front-end signal processing; obtaining effective numerical values ​​in the original image matrix, and performing background estimation; performing median filtering on the numerical values ​​of the original image matrix ; Perform dynamic and static binary segmentation on the values ​​obtained after background estimation; match the numerical target features after binary segmentation; perform high-noise elimination from the median-filtered values; match the target data after high-noise elimination with target features The data fusion processing; thereby obtaining the automatic tracking amount and completing the automatic tracking image matrix. The invention has the characteristics of simple algorithm, fast calculation and strong versatility. The invention effectively improves the operation speed and the efficiency and precision of target identification and tracking.

Description

technical field The invention relates to the basic technical field of underwater acoustic engineering, in particular to an image layer-based dynamic target automatic tracking method, which is used for anti-frogman sonar in underwater defense monitoring equipment. Background technique The anti-frogman sonar in the defense monitoring equipment has received widespread attention in the underwater defense of the inner layer of the port and moored ships. In order to ensure the safety of the port and ships, the anti-frogman sonar is used in the port and on the ships. Low-speed and small-scale targets such as UUVs and frogmen attempting to sneak into the port for reconnaissance, raids and destruction are implemented. The anti-frogman sonar developed uses the dynamic target automatic tracking technology based on the image layer. Various anti-frogman sonars have emerged for military vigilance and civil anti-terrorism needs. Anti-frogman sonar, as an active detection sonar for long-t...
