As shown in figure 1, a kind of landform threedimensional model generation method of the present invention, including：
Step 1：Gather the different angle image of landform to be reconnoitred；
In the step 1, at the identical height of distance landform to be reconnoitred, respectively from landform to be reconnoitred it is left and right,
Forward and backward and this five angles of normal position gather the image of landform to be reconnoitred.
In specific implementation, can be used unmanned plane by 5 sensors being carried on same flying platform simultaneously from it is left,
This right, forward and backward and normal position five angle acquisition images, obtain the information of ground object more complete and accurate.
Step 2：All images of acquisition are converted into corresponding cloud data；
In the step 2, all images of acquisition are separately input into Autodesk ReCap softwares, utilized
All images are converted to corresponding cloud data by the PHOTO TO 3D functions of AutodeskReCap softwares.
Wherein, Autodesk ReCap softwares are an independent application programs, and it can make by quoting multiple indexes
Scanning file (RCS) create cloud projection file (RCP).The software default is installed with AutoCAD 2014.
It can be started by Windows start menus or from Autodesk ReCap desktop icons.Autodesk can be used
Scanning file data conversion into point cloud format, can be checked and edited in other products by ReCap.Autodesk ReCap
Handle large-scale data set, enable you to polymerize scanning file, and it is cleared up, classified, spatial classification, compression, survey
Amount and visualization.
Cloud data is the direct sampled point for the body surface for being sampled to obtain to space object by spatial digitizer,
It is that the geometric attribute of body surface is most really recorded.The project main research be using unmanned plane oblique photograph technology as
Basis, change the limitation that conventional aerial survey can only use single camera from vertical angle shooting atural object in present situation is reconnoitred, lead to
Cross on same flying platform and carry more sensors, while image is gathered from the different angle such as vertical, side view and front-and rear-view, obtain
Take as-is data.So as to substantially reduce the economic cost and time cost of three-dimensional modeling data collection.
Step 3：Judge the wrong point in cloud data and bad point and be modified；
In specific implementation, in the step 3, judging the process of the wrong point in cloud data and bad point includes：
Cloud data is inputted into AutoCAD Civil 3D, generate corresponding surface, and mark out corresponding surface etc.
High line；
According to the density of cloud data, the contour of corresponding interval is set；
Whole topographic contour equispaced is compareed, it is relative herein if the density of contour is far smaller than equispaced
Wrong point and bad point be present in the cloud data answered；
If contour moves towards the irregular fluctuation of appearance, herein there is wrong point and bad point in corresponding cloud data.
Wherein, AutoCAD Civil 3D are a graphics softwares, there is provided unique styling mechanism, Shi Ge enterprises
Tissue can be with self-defining CAD and design standard, it is intended to towards Civil Engineering Design and the BIM of documentation
(BIM) solution.

Ensure the authenticity and accuracy of present situation.Point cloud model is directed into Three-dimensional Design Software, on the basis of real scene model
The establishment of the threedimensional model based on BIM technology is completed, accurately checks influence of the project to periphery region, and to possible in project
The problem of generation, is evaded in time.
Step 4：Designed a model using 3 d modeling software Revit to create, and it is whole with the progress of revised cloud data
Conjunction is handled, BIM model of the output with dimensional topography.
Wherein, Revit is the title of a set of groupware of autodesk, inc..The Revit groupwares are for architecture information
Model (BIM) structure, building designers' design can be helped, built and maintenance quality is more preferable, efficiency is higher building.
BIM can help architect to reduce mistake and waste, and improve profit and CSAT with this, and then create and can hold
The higher careful design of continuous property.BIM can optimize team collaboration, its support Architect And Engineer, contractor, build personnel with
Owner becomes apparent from, reliably links up design idea.
BIM supports the building that architect is better anticipated before construction after being completed, and makes them in nowadays increasingly complicated business
Retained its competitive edge in industry environment.Autodesk Revit Architecture softwares aim at BIM (BIM) and structure
Build.BIM is the integrated flow of structure based on from design, construction to the coordination of operation, reliable project information.By adopting
With BIM, building constructor can design and draw innovation item in whole flow process using consistent information, and can also lead to
Cross and accurately realize the visualization of architectural appearance to support preferably to link up, simulation actual performance so as to allow project parties understand into
Originally, duration and environment influence.
