Description
Technical field
The invention belongs to police service Information System configuration technical field, it is related to three-dimensional geographic information platform, more particularly, to one
The Multi-Source Image Data Fusion imaging system of the three-dimensional police geographical information platform of kind.
Background technology
The police geographical information platform of two dimension is more ripe in the application of each public security department at present.Two-dimension GIS is substantially real
The various functions related to police business are showed, such as：It is GIS map display function, map operation function, police map function, aobvious
Show GPS police cars function, map inquiry and positioning function, drawing function etc..Although public security department is met to a certain extent
Daily management mission needs, but two-dimension GIS is that the spatial information of three-dimensional is mapped as to the plane information of two dimension, is inevitably existed
It is excessively abstract in technique of expression, it is difficult to show the information such as humanity, environment, resource；Also lack telepresenc for user, be not inconsistent
Close the actual visual custom of people.Two-dimension GIS in terms of the intuitive that three-dimensional localization and information show there is limitation, by
This, arises at the historic moment for the construction demand of three-dimension GIS.
In recent years, three-dimensional visualization and virtual reality technology abroad security department and police unit increasingly by weight
Depending on the country has also carried out a few thing in this respect, realizes map operation, venue information locating query, security and police
The function of comprehensive displaying of the information of being engaged on electronic three-dimensional map, system is very fast in B/S Client browse maps, higher
Ground meets the actual combat demand of system.At present, the construction of police three-dimensional geographic information platform is still in the starting stage, is keeping magnanimity
Browsing for threedimensional model be smooth, on the Data Integration in existing public security two-dimentional system to three-dimensional scenic, existing two dimension is police
GIS-Geographic Information System be integrated into three-dimensional police geographical information platform and for specific transactions (strictly according to the facts current population's information inquiry,
Police service simulated flight etc.) the corresponding analysis and decision support module aspect of offer need further to develop and raising.
The original intention that digital city occurs just is intended in virtual digital world really express real world, and
Targetedly demand of specialty analysis and application are carried out thereon, play the core decision supporting capability of geographic information data.Therefore, number
The information of the target of word urban development, necessarily carrying objective world as much as possible, unlimited real simulation real world.So
And three-dimension GIS is developed so far, based on its application still is limited to browse with the visual presentation and roaming of city virtual scene.Study carefully
Its reason, it is due to the limitation of conventional digital cybercity construction technology：Conventional digital cybercity construction, mainly using people
Work modeling, sample texture, the technological means of sampling textures, it is the 3-d reproduction with the means realization of emulation to objective world,
Can not real simulation objective world；And each administrative department in the city such as public security, municipal administration, planning, gardens is it is desirable that can be truly anti-
Reflect " full information " city model of city present situation.
Improved constantly to realize that Police Information strengthened research and integrated management are horizontal, improve security administration, police strength deployment,
The GIS-Geographic Information System construction and management of the public business such as security guard, people have carried out long-term exploration, it is proposed that various each
The solution of sample.For example, Chinese patent literature discloses a kind of digital police three-dimensional geographic information system based on cloud storage
[application number：201320055443.1], by portable terminal, road monitoring terminal, security protection monitoring terminal, wireless communication networks,
Retrieval server, geographic information server, police data server composition, portable terminal, road monitoring terminal, security protection monitoring
Terminal connects wireless communication networks, and wireless communication networks connect geographic information server, police data server respectively.Its advantage
It is embodied in：The limitation of analyze data in the current routine information application system of public security organ is compensate for, comprehensively utilizes geographical letter
Spatial analysis functions specific to breath technology and strong Visualization ability, melt police service data message and spatial information
It is integrated.By monitoring distribution situation and real time execution situation of the various police work elements in space, its inner link is analyzed,
Reasonable disposition and scheduling resource, so as to improve the quick response of each police and collaboration disposal ability.
, still can not be from root although such scheme improves the performance of three-dimensional geographic information system to a certain extent
Solves previously described technical problem on this.Particularly three-dimensional scenic is still mainly using artificial modeling, sample texture, sampling
The technological means such as textures, it is to realize 3-d reproduction to objective world with the means of emulation, can not real simulation objective world.Base
City appearance simulation in the conventional digital urban construction pattern modeled by hand using sampling, can not really show objective generation
Boundary, while lack the expression of things in interior construction spacing and space with contacting.Due to the limitation of aeroplane photography, near-earth face
As missing so that outdoor scene three-dimensional is difficult to the model construction near the ground that becomes more meticulous, and can not meet the needs of observation application near the ground.
But conventional streetscape integrated technology near the ground, the mode of streetscape image frame is only switched to from two three-dimensional scenics, it is this
Streetscape image, its spatial relationships do not possess tight Fundamentals of Mathematics, can not be carried out with outdoor scene threedimensional model space accurate
Spatial match, also can not be with GIS data source slitless connection.
The content of the invention
Regarding the issue above, the present invention provides a kind of objective world validity of simulation it is high it is three-dimensional policely
