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
Plant three-dimensional police geographical information platform and system architecture.
Background technology
Current two-dimentional police geographical information platform is more ripe in the application of each public security department.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 meeting public security department to a certain extent
Daily management mission needs, but two-dimension GIS is the plane information that three-dimensional spatial information is mapped as 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 has limitation in terms of the intuitive that three-dimensional localization and information represent, by
This, the construction demand for three-dimension GIS arises at the historic moment.
In recent years, security department and police unit are increasingly subject to weight to three-dimensional visualization abroad with virtual reality technology
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 business information 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, police on the Data Integration in existing public security two-dimentional system to three-dimensional scenic, by existing two dimension
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.) corresponding analysis and decision support module aspect is provided it need further development and improves.
The original intention that digital city occurs just is intended in virtual digital world really express real world, and
Targetedly demand of specialty analysis is carried out thereon and is applied, play the core decision supporting capability of geographic information data.Therefore, number
The target of word urban development, the necessarily information of carrying objective world as much as possible, the unlimited real simulating reality 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, 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, are the 3-d reproductions with the means realization for emulating to objective world,
Objective world cannot truly be simulated；And each administrative department of 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.
To realize that Police Information strengthened research and integrated management level are improved constantly, 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：Compensate for the limitation of analyze data in the current routine information application system of public security organ, the geographical letter of comprehensive utilization
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 and collaboration disposal ability of each police.
Although such scheme improves the performance of three-dimensional geographic information system to a certain extent, still cannot be from root
Previously described technical problem is solved on this.Particularly three-dimensional scenic is still mainly using artificial modeling, sample texture, sampling
The technological means such as textures, are that the 3-d reproduction to objective world is realized with the means for emulating, it is impossible to truly simulate objective world.Base
Simulated using the city appearance of sampling in the conventional digital urban construction pattern of modeling by hand, it is impossible to really show objective generation
Boundary, while lacking in interior construction spacing and space the expression of things and 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 that becomes more meticulous near the ground, it is impossible to the need for meeting observation application near the ground.
But the streetscape integrated technology near the ground of routine, 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, it is impossible to carried out accurately with outdoor scene threedimensional model space
Spatial match, also cannot be with GIS data source slitless connection.
Additionally, commanding elevation analysis is a great problem of guard's security work.In guard's security work, guard scene, police
Defend residence, the commanding elevation investigation on guard line periphery is always work problem.Traditional working mode is real to scene by people's police
Make an on-the-spot survey, the mode investigated one by one is carried out.People's police detect by an unaided eye, hand-kept, because the factors such as weather condition are restricted, easily
Go wrong, and waste time and energy.
On the other hand, continuing to develop with GIS, its application field is constantly widened, scope constantly expands, technology constantly rises
Level, people's requirement in actual applications to GIS also more and more higher, new demand emerges in an endless stream.Meanwhile, process multi-source heterogeneous number
According to, operate the increasing problem such as cross-platform to be also badly in need of solving in the development of GIS.Data acquisition and renewal are to set up GIS
One significant investment of system, and data are carried out with the important foundation that system is set up after rational classification and coding is then.From
Seen using angle, successful generalized information system be largely dependent upon the synthesis of data and various modules with it is integrated.At present
Geographic information database generally using the data model of Object-and Relation type, i.e., expresses geographical entity with Space Elements object；With
Attribute list expresses the feature of the spatial entities.Traditional code need to be with known atural object factor data to rely on, to discrete point-like number
It is a kind of mode that definition space is bound with known place name address date according to being encoded.Geographic information encoding technology is current
Applied in GIS-Geographic Information System construction extensively, but, both for two-dimensional space coding, and can only map known accurate
Atural object.Traditional code, must be accurate because being tied to specific key element geographical entity, but in concrete operations, it is restricted
In data acquisition and the real-time and accuracy checked, it is difficult to accomplish to improve accurate, just cannot for incomplete information data
Encoded.
