Abstract

The invention relates to a multi-information fusion and wireless transmission system based on a GIS platform, which belongs to the technical field of information system, wherein position information of a target is acquired by a GPS or an external big dipper system; the included angle of the target and the due north direction is indicated by an electronic compass; the target is subjected to image pickup by a high-resolution camera; sound information generated by the target is acquired by a sound pick-up; various messages of the acquired target are subjected to fusion processing; an electronic map is edited; proper graphic symbols are marked on the electronic map which is updated in real time; as for various target primitives after fusion processing, a regional situation map is formed by taking regions as a unit; in order to reduce the data quantity, the regional situation map is drawn by an independent map layer and stored in a file format; and the generating time of the situation map is taken as a filename, and the file is transmitted to an information center by wireless technology. The multi-information fusion and wireless transmission system based on the GIS platform can realize teletransmission through a relay, and is suitable to be used in situations such as wild mining, anti-terrorism, patrol, monitoring and reconnaissance.

Description

technical field [0001] The invention relates to a multi-information fusion and wireless transmission system based on a GIS platform, which transmits a regional situation map formed through wireless technology, and belongs to the technical field of information systems. Background technique [0002] In recent years, geographic information system (GIS) has developed rapidly. It is a technical system that uses computers as a means to manage (storage, retrieve, query, display, and analyze) various spatial data and attributes in the real world. None of the existing GIS platforms involves the collection and processing of multivariate information on the target primitives on the electronic map. Contents of the invention [0003] The purpose of the present invention is to provide a multi-element information fusion and wireless transmission system based on the GIS platform. For the existing GIS platform does not involve the collection and processing of the multi-element information o...
