Description
Technical field
The present invention relates to a kind of roadbed, particularly to a kind of roadbed using unmanned plane to measure, belong to road engineering survey
Field.
Background technology
Subgrade cross section measurement is the task that always road survey workload is maximum, before subgrade construction, designing institute
Unit in charge of construction is given at the measurement control point carrying arch, and first unit in charge of construction is controlled encryption a little and translocation, then carries out roadbed
The calculating of cross-sectioning and earth work amount is to check drawing quantities.In the past subgrade cross section measure use level gauge with
Taped measurement method, this method needs turning point in the area that the discrepancy in elevation is big, the slow inefficiency of speed.Trigonometric Leveling by Total Station and seat
Mapping amount and RTK height fitting method improve work efficiency, but this method is all a measuring method, it is impossible to carry out face survey.
The common ground of these methods is that field process amount is the biggest.And Aerial Surveying Technology greatly reduces topographic field process amount, can
To carry out planar survey, but precision is the highest, and height accuracy is lower than plane precision.After three-dimensional laser scanner occurs, planar survey
Precision is improved.This equipment is to utilize laser scanning and ranging, per second measure and record hundreds of thousands cloud data generate
The three-dimensional graph of ground surface, is integrated with laser scanning and ranging, GPS, IMU (Inertial Measurement Unit), CCD digital camera simultaneously
Vehicle-mounted three-dimensional mapping system come into the market, formula three dimension laser scanning surreying can be moved.
Summary of the invention
The present invention provides a kind of roadbed using unmanned plane to measure, by replacing traditional point to survey with three-dimensional laser scanner
Amount is carried out field operation topographic survey, effectively solves that the method for existing measurement roadbed is little without dot density and relatively low the asking of precision
Topic.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of roadbed using unmanned plane to measure of the present invention, including unmanned plane course line track, roadbed expropriation of land line, massif and machine
Carrying portable three-dimensional laser scanner, the two ends of described unmanned plane course line track are equipped with described roadbed expropriation of land line, described massif
Top is provided with described unmanned plane course line track, and the described airborne portable three-dimensional that is arranged over of described unmanned plane course line track swashs
Photoscanner.
As a preferred technical solution of the present invention, described airborne portable three-dimensional laser scanner is installed on unmanned plane
Lower end.
The present invention is reached to provide the benefit that: a kind of roadbed using unmanned plane to measure of the present invention, applied widely, essence
Degree also can reach the required precision that subgrade cross section is measured, and field operation is measured fast, and the process workload of interior industry data is big, can be with field operation
With interior industry integrated measuring, the density of three dimensional point cloud stereomodel point is big, can arbitrarily select transverse section spacing, and landform is multiple
Miscellaneous area can select mono-sectional drawing of 5m or mono-sectional drawing of 1m to improve the precision calculated, and the present invention has aerophotogrammetric field work speed
Spend the feature that fast and interior industry workload is big, use unmanned plane low latitude certainty of measurement to increase.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein
Execute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment
As Figure 1-3, a kind of roadbed using unmanned plane to measure of the present invention, levy including unmanned plane course line track 1, roadbed
Ground wire 2, massif 3, mountain height scale 4 and airborne portable three-dimensional laser scanner 4, the two ends of unmanned plane course line track 1 are equal
Be provided with roadbed expropriation of land line 2, and massif 3 top be provided with unmanned plane course line track 1, and unmanned plane course line track 1 be arranged over machine
Carry portable three-dimensional laser scanner 4.
Airborne portable three-dimensional laser scanner 4 is installed on the lower end of unmanned plane, moves formula scanning, collects data,
Data generate 3D digital three-dimensional model or DEM, DOM, DLG map in computer, and are converted to the dat data form of south cass
Generate numerical map.
Concrete, when the present invention measures roadbed, because the precision that total station instrument coordinate method is measured is higher, can only be a measurement,
Obstructed optionally turning point is more；GPS-RTK is not required to intervisibility to be put, setting height(from bottom) measuring instrument under unmanned plane, measures the height of massif 3
Spending, and unmanned plane during flying maximum height is affected by massif 3, the mainly height anomaly of alpine region, aerophotogrammetric field work is quickly
But precision is the highest, field operation uses airborne portable three-dimensional laser scanner 4 to carry out the collection of ground cloud data, and gathers number
