Abstract
The present invention relates to the method that a kind of vector data superposition DSM automatic batch generates threedimensional model, it comprises the following steps：(1) using the profile information of vector data, the positional information of surface buildingses is got, and is shown in three dimension system；(2) by DSM matched algorithms, the corresponding surface buildingses elevation information of vector data is obtained, elevation information is deposited into shp data；(3) texture need to be such as added, by the file of manual configuration data texturing, threedimensional model is quickly generated.This method can rapid batch modeling, business demand can be met again, moreover it is possible to greatly reduce cost.
Description
Technical field
The invention belongs to geographic information system technology field, it is related to a kind of vector data superposition DSM automatic batch generation three
The method of dimension module.
Background technology
Three-dimensional entity model be in the application of all trades and professions it is quite varied, different industries to the demand of threedimensional model not
Together, so the production method of threedimensional model is also diversified.In the prior art, the general threedimensional model that makes generally is used
3DMax is manually modeled, and the model produced is finer, and model has the attribute of singulation；Oblique photograph of new generation post-processes skill
Art can realize the automatic rapid modeling of batch, and model accuracy is high, the cycle is short, model has real three-dimensional coordinate, but model
Singulation is unable to, without entity attribute.
With the development and application of three-dimension GIS technology, all trades and professions are presented explosion type to the demand of three-dimensional entity model and increased
It is long, but different industries is also not near identical to the demand of threedimensional model.In the prior art：
Artificial modeling, is generally generated threedimensional model and is generally manually modeled using 3DMax, the model produced is finer, but
It is time cycle length, human cost height.The field higher to modelling effect requirement is generally used for, such as three-dimensional scenic spot, three-dimensional society
Area, digital venue, digital memorial museum etc..
Oblique photograph post-processing technology of new generation can realize that automatic lot is modeled, and model production precision is high, the cycle is short,
But the winged cost of boat, software cost are higher.It is generally used for the field higher to modal position required precision, such as urban planning,
Traffic, fire-fighting etc..
But for some, model accuracy less demanding fields less demanding to modelling effect, both the above technology is just
Do not apply to, one side cost is too high, on the other hand do not need so high precision, or relatively good effect.
The present invention be badly in need of find one kind can rapid batch modeling, business demand can be met again, moreover it is possible to substantially reduce cost
Method.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art and provide a kind of vector data superposition DSM automatic batch lifes
Into the method for threedimensional model, this method can rapid batch modeling, business demand can be met again, moreover it is possible to greatly reduce cost.
To achieve the above object, the technical solution adopted by the present invention is as follows：
The invention provides the method that a kind of vector data superposition DSM automatic batch generates threedimensional model, it includes following
Step：
(1) using the profile information of vector data, the positional information of surface buildingses is got, and in three dimension system
It is shown；
(2) by DSM matched algorithms, the corresponding surface buildingses elevation information of vector data is obtained, height is believed
Breath is deposited into shp data；
(3) texture need to be such as added, by the file of manual configuration data texturing, threedimensional model is quickly generated.
The method for generating threedimensional model according to above-mentioned vector data superposition DSM automatic batch, comprises the following steps：
(1) vector data superposition DSM data, automatically extracts vector data elevation, and altitude data is deposited into shp data text
In part；
(2) vector data texture is configured, in certain height is interval, data texturing is set；
(3) figure layer title, data path, texture pathway of the modeling of input batch etc., and specify data visualization scope：
(4) Mass production threedimensional model.
Compared with prior art, beneficial effects of the present invention：
The method of batch modeling of the invention, without relying on the modeling tool of specialty, such as 3DMax, StreetFactory,
SkyLine etc., just three-dimensional modeling can be both improved by three-dimensional GIS platform with the substantial amounts of threedimensional model of the generation of rapid batch
Efficiency, the cost of three-dimensional modeling is reduced again.
