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 1
As seen from Figure 1, the implementation process of the present invention includes field operation and interior industry two aspects of work.Field process includes roadbed
Setting-out, unmanned plane position, shoot, transmit image and make a return voyage；The work of interior industry includes image procossing and computational analysis.
First, roadbed setting-out.As in figure 2 it is shown, a point of selected known elevation is as zero, i.e. first stake position
Point, sets a stake site (available total powerstation is accurately positioned) along the direction that highway extends every 20 m, and each site is inserted
Enter root length degree 0.5 m, diameter 1 cm circular timber as labelling.The sum in stake site is by the total length of this section of roadbed certainly
Fixed.
Secondly, unmanned plane location and shooting.Unmanned plane installs varifocal high-definition camera, connects GPS system, passes through in advance
The coordinate in program input target stake site, allows unmanned plane fly to, at top 50 m in this site, shoot roadbed.
3rd, transmission image also makes a return voyage.Real-time the passing back of image unmanned plane photographed by special-purpose software and network
In the computer of Office Area, unmanned plane is then allowed to make a return voyage and pack up.
4th, image procossing.After the staff of Office Area receives the image that unmanned plane photographs, image is carried out black
Whitening processing (filters out tone and saturation infromation, only retain monochrome information), denoising, sharpens edge so that hold according to image
Easily it is further analyzed.
Finally, computational analysis.The image processed is analyzed, owing to stake site spacing in roadbed determines that,
Corresponding width of subgrade accurately can calculate according to geological information, by the width of subgrade of different elevation different locations comprehensively one
Rise, it is possible to draw subgrade cross section figure, it is judged that whether subgrade construction reaches standard.Image procossing and computational analysis, Ke Yiyong
MATLAB software programming Automatic Program realizes.
When the application present invention carries out subgrade cross section measurement, roadbed often fills or cuts out one layer it is necessary to carry out once unmanned
Machine is taken photo by plane, and records corresponding width of subgrade and the elevation in stake site, coordinate information, in order to after subgrade construction is complete accurately
Calculate the area of section of roadbed.Relative to traditional measuring method, field personnel only needs skilled operation unmanned plane,
Avoid substantial amounts of traditional instrument to measure and the climbing of deathtrap, improve work efficiency and safety.
This kind subgrade cross section based on unmanned plane measuring method, can measure width and the transverse section chi of roadbed efficiently
Very little, raising certainty of measurement, and the workload of in-site measurement can be effectively reduced relative to traditional measurement method, improve and measure
The safety of personnel.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
