Description
Technical field
The invention belongs to 3-D technology field, particularly relate to a kind of modeling method based on integration under very dimensionally Shangdi and system.
Background technology
Statistics shows, in the underground pipeline system damage accident of the U.S., because excavating improper causing more than having three one-tenth.To this, the U.S. establishes GIS platform, and utilizes generalized information system accurately manage and locate, as long as United States citizen dials " 811 " special line, just can tell digger's pipeline details.China's pipe-line construction initial stage is disorderly and unsystematic, later period maintenance no supervision, and road slide fastener occurs again and again.Along with the acceleration of Urbanization in China, pavement excavation also gets more and more.What breakage in installation underground utilities caused cuts off the water, stop the supple of gas or steam, have a power failure and communication disruption Frequent Accidents.According to underground utilities Professional Committee of China Urban Planning Association annual meeting statistics: 2008 ~ 2010, the underground utilities accident of national only media report, just has 5.6 (within 3 years, amounting to 6132) average every day.Wherein the disconnected and construction wrong of excavator just accounts for 62.7%, and the direct economic loss that the pipe network accidents that the whole nation is caused because of construction every year causes reaches 50,000,000,000 yuan, every year due to direct economic loss about 200,000,000,000 yuan that pavement excavation causes.
Also day by day urgent to the demand of underground spatial information as can be seen here.For this reason, State Council have issued " General Office of the State Council is about the instruction strengthening City Buried Pipeline implementation management " with regard to underground utilities implementation management separately." suggestion " explicitly points out " before the end of the year 2015, completing General Survey for Urban Underground Pipeline, and set up IMIS, and work out underground utilities unified plan." visible government constantly promotes underground pipe network attention degree.
Constituent parts is widely used be now two dimensional CAD system to draw the distribution of pipe network, minority employs three-dimensional CAD to express the form of pipe network, and part 3DMAX designs and produces pipe network design sketch.But these methods for designing, all can not embody the three-dimensional geographic coordinate of underground pipe network, are unfavorable for carrying out spatial analysis, attribute query and visualized management.
Current planning and designing method and deficiency
1, classic method can not carry out attribute query and spatial analysis
Constituent parts is widely used be now two dimensional CAD system to draw the distribution of pipe network, minority employs three-dimensional CAD to express the form of pipe network, and part 3DMAX designs and produces pipe network design sketch.But these methods for designing, all can not embody the three-dimensional geographic coordinate of underground pipe network, are unfavorable for carrying out spatial analysis, attribute query and visualized management.
2, build two-dimension GIS system and lack three-dimensional information, be unfavorable for management and analyze
The special pipelines ownership unit of urban establishes synthetical city underground pipeline infosystem and special pipelines infosystem.But these overwhelming majority are all two-dimension GIS systems.Two-dimension GIS just all carries out the simplify processes to equatorial projection to the various geographic object be in three dimensions, cause the loss of the geometric position information on third dimension direction (i.e. vertical direction), space topological information and part of semantic information, intactly can not react objective world.Therefore, geography information expressed by two-dimension GIS be solidify, plane.These works can generate the three-dimensional model of underground utilities and display fast according to the information such as the depth of burying of all kinds of underground utilities, length of pipeline, pipeline specification, can understand the parameters such as the relative position relation of underground pipe network and connectedness in time.The simulating reality that underground spaces all in regional extent and topographic map data generate is observed, roamed, and in observation figure, realizes the inquiry of any spatial entities attribute information.
3, above and below ground integrated modelling is not carried out
But descend three-dimensional information or inadequate only, in pipeline accident, need more and more to go up the process that atural object carries out accident in combination; Need the atural object gone up in combination comprehensively to analyze when construction, thus formulate rational arrangement and method for construction.
4, only pay close attention to three-dimensional atural object on the ground, do not pay close attention to underground pipe network three-dimensional configuration
Have at present and much make electronic three-dimensional map, but distribution and the form of what great majority were paid close attention to is facility on the ground, do not pay close attention to the state of this city operations lifeline of underground pipe network, more do not pay close attention to and how will organically combine with underground coordinate on the ground, cause the problem of pipe network massive losses to reduce surface road repeatedly to excavate.
5, the scanning of laser car costly, is unfavorable for small area modeling on the ground, and can not be used for underground modeling
The widely used laser car scanning of current ground three-dimensional map, the mode of the large batch processing of professional software sets up model on the ground on a large scale.The feature of this mode is that batch is large, soon.But shortcoming is, expense is high.The rent in equipment one Tian Chu street just can reach 50,000 yuan, does not also comprise the disposal cost in later stage.Therefore, for the small space that school, community, manufacturing district, hospital are such, laser car is used to be extremely uneconomic.Further, laser car can not carry out the modeling of underground pipe network.
The whole cost in this integrated virtual campus, works above and below ground, except labour cost, does not almost have expense.Because it is intrinsic that digital camera is laboratory, software is study version (not costing use).Namely 3 skilled student times of one week construction period in integrated virtual campus, above and below ground.Total funds 5000, cost is extremely low.Therefore, to be with a wide range of applications and economic worth.
6, traditional mapping method is wasted time and energy
Set up a Geography Information System on Campus, need to survey and draw whole campus, the time is long, Ren Yuanduo, also needs much to survey and draw specialized equipment in the past.These works adopt and intercept campus remote sensing base map in Bigemap map interceptor, and correct with gps data, and precision reaches 1 meter.Decrease the human and material resources in mapping campus, financial resources and time.
7, GIS software can not set up become more meticulous model and special-shaped model
Because GIS software itself is a geography in formation software, fine and smooth not to the expression of model, particularly special-shaped model.And 3DMAX software can very finely expression model, does not just have geographic coordinate information.Therefore, 3DMAX software and GIS software effectively combine by these works, each the chief, define existing accurate three-dimensional geographic coordinate, express again meticulous model.
Based on above problem, be badly in need of the three-dimensional modeling realizing above and below ground integration, the pipe network of upper and lower all kinds of complex structure, wide variety, substantial amounts can be taken into account, upgrade more in time and supervise data.By spatial analysis and attributive analysis, avoid the conflict etc. of lower facility on the ground in pipe network accidents and process of construction.
