Embodiment Construction
[0033] The present invention is based on the Internet information-based dynamic monitoring method for important ship targets, which includes the automatic discovery of massive spatio-temporal data of ship targets based on Internet information, unified data representation of multi-source ship target information in a big data environment, and deep correlation and correlation of ship targets under the fusion of spatio-temporal data. Dynamic monitoring, multi-source ship target trajectory analysis and detection, fast ship target monitoring method based on perceptual compression theory.
[0034] The first is to use the related technologies of web crawlers to obtain massive spatiotemporal data related to target ships from the Internet (including Web news or social media such as Twitter and Facebook, AIS systems, and remote sensing satellite websites and other information data sources). Excavate the mechanism and metadata management method of automatically discovering relevant distrib...

The invention discloses an internet information-based important vessel target dynamic monitoring method. According to the method, news texts on the internet and target vessel-related information among global massive satellite data are mined, multiple disclosed satellite spatial-temporal data on the internet domestic and abroad is used as a data source, and text, optics, multi-spectrum or hyperspectrum, infrared, SAR, AIS data sources are fully used for mining multi-source heterogeneous information based on big data, so that deep correlation of spatial-temporal data in dynamic monitoring of important vessel target has higher correction rate, early-warning time for important target data is shortened, trace detection of the target vessel is more accurate, and the method provides technological support for additional monitoring methods for important vessel targets on the sea.
Description
technical field [0001] The invention belongs to the relevant field of computer application, specifically, it is a dynamic monitoring method for important ship targets based on Internet information, which can be applied to the fields of sea surface traffic monitoring, ship search and rescue, fishery management and the like. Background technique [0002] The dynamic monitoring of ship targets on the sea surface is a topic that has attracted much attention in the field of remote sensing image processing and analysis. Its core task is to determine whether there are target ships in remote sensing images, and to monitor, classify and accurately locate them. [0003] Automatic Identification System (AIS system for short) is a new auxiliary navigation system based on GPS technology, very high frequency (VHF) technology and self-organizing time division multiple access technology (SOTDMA). , environmental protection and search and rescue functions. According to different platforms, ...
