Background technology
Earthworks calculation work refers to compared with original place, calculate the cubic metre of earth and stone for more than designed elevation face needing to excavate
The earthwork backfilled is needed below amount and designed elevation face, and then the cubic metre of earth and stone that place was transported or transported in plan can be extrapolated
Amount.During foundation excavation, the work for transporting or transporting the place cubic metre of earth and stone need to be reduced to greatest extent.
The most important content of earthworks calculation work is to gather the actual elevation in original place, the weight calculated as the cubic metre of earth and stone
Initial data is wanted, the precision of the data directly affects the validity and science of whole balancing work achievement.Conventional method is to adopt
The method of fixed point collection elevation is carried out to construction site with RTK measuring apparatus to obtain initial data, the method is by field division
Into some length of side identical square grid nets, then by Site Design absolute altitude and the natural ground elevation that the measures side of being labeled in respectively
On the angle point of grid, the difference of Site Design absolute altitude and natural ground elevation is the construction height of each angle point.Then count respectively
The excavation and filling earthwork in each region is calculated, finally the earthwork in each grid is added and draws the final excavation and filling cubic metre of earth and stone
Amount.Because construction site area is often larger, survey crew can only choose certain operating room away from measuring, the effect of gathered data
Rate is relatively low, and simultaneously for the construction site of topographical elevation difference big rise and fall, the earthwork error measured can be very big, and measures
Point for impermanency mark, be frequently subjected to artificial disturbance or the earthwork sedimentation and cause measure point data can not repetition measurement checking.
The content of the invention
The technical problem to be solved in the present invention is, the defects of for prior art, there is provided one kind combine oblique photograph,
RTK and BIM technology cubic metre of earth and stone survey calculation method.
The technical solution adopted for the present invention to solve the technical problems is：Construction one kind combines oblique photograph, RTK and BIM

S8 is dug to three-dimensional terrain model, mold filling is intended, and calculates earthwork volume.
In such scheme, the laying principle of photo control point and checkpoint is uniform in target area surrounding in the step S2
Arrangement is respectively no less than the coordinate point identification of three.
Boat is performed in such scheme, in the step S3 take the photograph the flight equipment of operation its flight range be greater than target area
Scope, when the scope of target area exceedes flight equipment single rack time air cover domain, need to ensure between adjacent air cover domain extremely
A rare flight path is overlapping.
The present invention is quick and precisely gathered image to target area place using oblique photograph technology, recycles RTK to set
The standby data to acquisition are corrected, and export accurate cloud data, are generated finally by BIM softwares are imported into after processing
Three-dimensional terrain model, three-dimensional terrain model is dug, mold filling plan, calculate quantities, worked for earthworks calculation.
Implement a kind of combination oblique photograph, the cubic metre of earth and stone survey calculation method of RTK and BIM technology of the present invention, have with
Lower beneficial effect：
1st, the present invention can precisely, it is quick, efficiently accomplish field operation measurement operation, the initial data collected can be imaged by outdoor scene
Cloud data after software output calibration, and reprocessing generation three-dimensional terrain model directly can be identified by BIM softwares；
2nd, the present invention forms a set of foundation from data acquisition to model and, again to the fullpath of quantities calculation, improves native stone
The efficiency that side measures and calculated, makes that the initial data precision of acquisition is higher, and the performance data of calculating is more accurate；
3rd, the process data in the present invention is automatically performed by electronic equipment and software, has evaded artifact interference, is exported
Outcome data there is the characteristics of uniqueness, and data result can be verified, especially cloud data and photo control point and school
Two-way verification can be realized between testing a little.
Brief description of the drawings
Fig. 1 is the schematic diagram of implementation steps of the present invention.
Fig. 2 is the flow chart of the implementation process of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples, and certain following embodiments should not be understood to this
