Description
Technical field
The present invention relates to the detection technique field of track traffic, and in particular to one kind visualization Metro Clearance Detection.
Background technology
In urban track traffic industry, the development of Metro Clearance detection technique is increasingly ripe, by substantial amounts of development test,
A variety of Metro Clearance detection devices are developed.From operation principle, contact type measurement and non-contact measurement, just can be divided into
Take formula measurement and vehicle load measurement.Detected for the section of subway long distance tunnel, generally using vehicle load measurement, and it is portable
Measurement is used only for the additional survey of some indivedual sections.
At home, a kind of home-built equipment of generally use in subway construction, according to facilities clearance size, makes a frame and consolidates
Due on flat car, drawn using diesel locomotive.When frame passes through, it is believed that without generation of transfiniting；And when frame by
To when hitting, wiping extension, there is object fouling of clearance gauge.Such a mode can only adapt to a kind of gauge requirement, when gauge changes, need
Replace frame.The price of a usual frame is about at 10,000 yuan or so.
On the basis of such scheme, have by designing telescoping mechanism to adapt to the Extensible framework of different gauge requirements.
The mechanism adjusts the position of frame edge in subregion design swing arm mechanism, and is determined by portable measuring device
Position.But on whole subway line, limit changes are more, adjustment every time is required for the more time, and measurement efficiency is not high.And
And the size of frame is confirmed that error is larger by portable measuring device.In traveling, vibration is also possible to cause frame
The displacement at frame edge, causes the error of measurement.But such a frame is lower relative to aforementioned schemes cost, and applicability is also stronger.
Above two scheme has all detected whether object fouling of clearance gauge using frame movement, but the specific orientation to transfinite needs
Want operating personnel to estimate to judge.Some slightly invade the object of limit, or the object invaded at the same time probably manually observe when
Wait and omit, it is necessary to which repeatedly investigation just can confirm that whether there is the object for invading limit.
Chinese patent CN201210395978.3 constitutes a subway with dynamic compensation using 8 groups of area array cameras and limits
Boundary's measuring system, is installed on railcar.System that employs 8 supporting laser light sources, the means of image procossing are utilized
Subway tunnel profile is extracted, is spliced to form complete tunnel contour.The complete equipment also uses velocity sensor and electronics
Tag Radio Frequency instrument is positioned, and realizes that information is corresponding with mileage.But the complete equipment cost is high, and there is no separate carrier, need
It is installed on vehicle, can not uses in the construction process.
Chinese patent CN201310547187.2 provides a kind of detection method of tunnel cross-section.The equipment has 7 groups at a high speed
Camera, every camera coordinate 2 lasers, 2 complete tunnel cross-sections can be formed on tunnel cross-section, utilize image procossing
Mode extract the position of optic strip, actual tunnel cross-section coordinate is calculated by system calibrating technology, realizes tunnel cross-section detection
Function.However, the complete equipment does not have speed measuring device, without compensation, it is necessary to realize dynamic detection by mobile vehicle yet.
Chinese patent CN201610532113.5 has built a set of tunnel clearance using several laser range finders and host computer
Device for dynamically detecting.The device by detect tunnel face every bit to the distance of orbit centre and realize railway tunnel section into
Picture.It draws tunnel cross-section by establishing virtual coordinate system.In addition, the complete equipment is compensated without dynamic, measured in dynamic
Shi Huiyou large errors.
In conclusion a kind of a visualization Metro Clearance Detection of design, cost of manufacture is cheap, no blind-spot detection,
Detection is accurate, can also effectively be captured while Metro Clearance information is measured and invade limit object, to facilitate testing staff to identify and apply
Worker person rectifies and improves, and becomes skilled artisan's technical problem urgently to be resolved hurrily.

Laser radar two of the present invention, it is back-to-back, horizontal；6, camera, with 8mm camera lenses, each 57.8 ° of field-of-view angle；
Region between actually detected two rail of compensation device.
The position of laser radar and compensation device can obtain it afterwards with rail level center according to actual conditions adjusting position
For coordinate (x1, y1), (x2, y2), (x3, y3), (x4, the y4) of origin.
Left half laser radar the data obtained is drawn according to (x1, y1), and right half laser radar the data obtained is painted according to (x2, y2)
System.The Metro Clearance of the actual circle drawn, is with (x1, y1), on the basis of the center (x0, y0) of (x2, y2).
The general value of distance that (x0, y0) arrives (x3, y3) and (x4, y4) respectively is considered constant.That is, laser thunder
The triangle formed up to center and two laser radars is constant.
The angle of compensation device and rail level is adjusted definite according to actual conditions.May thereby determine that (x3, y3) with
The value of (x4, y4), and then can determine (x0, y0).In this way, compared to directly in static state, obtain (x0, y0) reach one it is dynamic
The effect of state compensation.Rotation can be compensated, is vibrated.Ideally compensation and the triangle of radar center are constant, and actual
In can still change, thus compensation is reached more preferably effect as close to radar center；By above-mentioned compensation,

Mileage information measured by velocity sensor is together deposited and is shown on a display screen, work in industrial control computer
After industry control computer obtains gauge information, compared with the standard gauge information of the corresponding mileage information of prior typing, comparison is adopted
With ray method, x-axis is done once, and y-axis is done once.So obtain invading the coordinate (x5, y5) of point of accumulation and standard gauge crosspoint.
In view of having blind area close to camera, therefore 6 cameras can not obtain 360 ° of the visual field, but camera fields of view is only
Need to cover bounds on rail level.Each camera has the corresponding coverage that gets a clear view, when (x5, y5) is fallen into
During its scope, reference numeral is exported, using trigger, camera is taken pictures, then two cameras are taken pictures at the same time for overlapping region.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit the protection model of the present invention
Enclose, as long as the present invention body design thought and that mentally makes have no the change of essential meaning or polishing, it is solved
Technical problem it is still consistent with the present invention, should be included in protection scope of the present invention within.
