A kind of retrieval information analysis system

Abstract

The present invention relates to a captured information analysis system. The captured information analysis system includes a host unit and a plurality of image capture units. The host unit pre-stores a first map, which is the map data of the first area, and the captured information is analyzed. The system is used for analyzing a plurality of captured information captured by a plurality of image capture units in the first area. There is a data connection between the host unit and the plurality of image capture units, and the multiple image capture units pass data The connection transmits corresponding multiple captured information to the host unit, each captured information of the multiple captured information includes corresponding position information, direction vector information and viewing angle information, and determines the attention area of ​​each captured information To form a plurality of attention areas, the host unit analyzes and obtains overlapping areas according to the plurality of captured information and the first map, wherein, if the number of overlapping areas in the plurality of attention areas is greater than a preset number, The host unit then outputs the overlapping area.

Description

technical field [0001] The invention relates to an information retrieval analysis system, in particular to an information retrieval analysis system for quickly analyzing the location of hot events. Background technique [0002] When an event occurs and is widely disseminated, the commonly used first attributive of the event is geographical location information, so if the information of possible hot event places is quickly reported, users can intuitively and visually understand the geographical location of the event location, so analyzing geographic location information is crucial to understanding the aforementioned hot events. [0003] However, at present, the acquisition of location information of hotspot events is relatively delayed, and it takes a period of time to spread and ferment to form an impact. In this way, in the early stage of an event, the surrounding people or the government cannot quickly know the occurrence of the event, which may lead to Some hysteresis oc...
