Description
Technical field
The present invention relates to machine vision and photogrammetric technology field, more particularly to a kind of Tunnel week deformation monitoring system
System and method.
Background technique
With the development and progress of China's economic society, the freeway net in China is increasingly developed and mature.Current
In highway composition, tunnel is an important component part.Especially more mountain topographies such as Sichuan, Yunnan intricately
Area, tunnel construction are homely food, even more will appear a large amount of Super Long Tunnels.However in terms of present Tunnel Engineering monitoring
In, method main or using artificial detection.There are many this artificial detection methods, such as geodesic method, INSAR skill
Art, 3 D laser scanning, GPS technology etc. obtain the deformation in Tunnel week with this.
Since situation is complicated in use in tunnel, the appearance situation of tunnel deformation is difficult to grasp in advance, if tunnel
Deformation occurs but non-monitored personnel grasps, it might therefore cause huge economy and personal casualty loss.It is existing at present
Common monitoring Tunnel week deformation technology mainly carries out deformation monitoring using scanning device and GPS technology.Traditional monitoring
Mode is mainly instrument cost valuableness, can consume a large amount of manpower and material resources, data processing time is longer, degree of intelligence is low, space-time
Poor continuity；Especially in the detection of Super Long Tunnel, specific implementation has very big difficulty.Not for such detection mode
Foot, the machine vision technique occurred in recent years realizes the intelligence to the monitoring of entire tunnel deformation, with traditional Scanning Detction
It compares, the present invention utilizes machine vision technique, is intelligently taken pictures in conjunction with mechanical automation using CCD camera, realizes intelligence comprehensively
Detection, has the characteristics that space-time expending is strong, degree of intelligence is high, precision is high, operability is excellent etc., therefore can be widely used in tunnel
Hole week in transformation safe monitoring and warning.
Summary of the invention
The purpose of the present invention is overcome existing for the week technology for deformation monitoring of existing tunnel hole it is time-consuming and laborious, involve great expense, and
Do not have space-time expending and the intelligentized deficiency of high level, a kind of Tunnel week deformation prison based on machine vision technique is provided
Examining system and method.
The system is mainly held by binocular CCD camera, image capture card, sliding slot, image processing software and database, camera
Platform, input-output unit, remote control terminal composition.It is able to achieve comprehensive monitoring Tunnel week deformation, accurate grasp may deposit
Potential faults, reduce loss.
Technical solution of the present invention is:
In the period for not influencing tunnel normal use, the wave that can cover tunnel requirements detection length is laid in tunnel both sides
Shape wave metal sliding slot, metal sliding slot are mounted on above the tunnel hole Bi Ren, based on not influencing tunnel internal structure normal work
It is required that binocular CCD camera is mounted on metal sliding slot by camera cushion cap.
Tunnel left camera shoots Tunnel week right panel, and tunnel right camera shoots Tunnel week left side picture.It mentions
It is preceding that binocular camera is controlled by remote control terminal according to laying good corresponding index point is calculated, in an index point corresponding position bat
It takes the photograph after completion, camera cushion cap is moved to next index point corresponding position with sliding slot automatically, and if desired shortening time of measuring can
More binocular CCD cameras are set while measuring work.
The image obtained by binocular CCD camera is all stored in USB screen capture card, can be first by image processing software
It is pre-processed with binocular CCD camera itself, removes influence factor that may be present.Binocular in binocular CCD camera is taken the photograph again
As the photo that head is shot, it is passed in image processing system, carries out image analysis, obtain corresponding Tunnel week deformation data.
As further technical solution of the present invention, it is configured with binocular head in the binocular CCD camera, is two telecentricities
Lens, a mesh are common full-color zoom lens, and a mesh is optics Penetrating Fog zoom lens, are judged by mist sense coefficient, are realized
It is quickly converted, Penetrating Fog processing is carried out using Penetrating Fog algorithm to the image frame of shooting.
As further technical solution of the present invention, the pretreatment refers to that binocular CCD camera itself carries narrowband filter
Mating plate, each shooting point correspond to the reflecting sign point of each laying, pass through the filtering of narrow band filter, energy when camera is shot
The interference of background miscellaneous light is enough eliminated, Xiang Zhiliang is adopted in raising.
As further technical solution of the present invention, described image processing system refers to through binocular vision related algorithm,
Tunnel week deformation related data is obtained, is off-line calibration the step of usual algorithm process, binocular correction, binocular ranging and view
Difference figure post-processing, wherein the purpose of off-line calibration is the internal reference for obtaining camera and outer ginseng.Because the binocular CCD camera is using remote
Heart camera lens, on these basic algorithms, we use a kind of new high-precision polar coordinates matching algorithm；Ordinary lens at
As model has a projection centre, there are multiple polar planes to intersect at baseline, telecentric lens imaging model is a parallel projection
Model.Therefore, projection centre at infinity, each polar plane be it is parallel, so polar curve be also it is parallel, straight line and
Polar plane is one-to-one.Characteristics simplified point matching primitives of the telecentricity binocular vision in calibration plate reference planes, because
Polar plane for telecentric system be all it is parallel, the row on polar plane is also parallel to each other with the row of left and right camera lens coordinate plane.Cause
This, after obtaining each row corresponding relationship of left and right camera lens coordinate, if determining a point in left camera lens, the matching in right camera lens
Point must be in a line in right camera lens coordinate system.Using the constraint condition, binocular vision point matching primitives are simplified, are reduced
The interference of other factors；Improve computational accuracy.
As further technical solution of the present invention, the binocular CCD camera is by USB screen capture card and remotely
Image processing software and database in control terminal carry out data connection.
As further technical solution of the present invention, the corrugated metal sliding slot refers to that metal sliding slot is installed with waveform
It on the wall of tunnel or so hole, can be matched with camera cushion cap, realize the multi-angle many areas shooting of binocular CCD camera, greatly
It is big to eliminate monitoring dead angle.
As further technical solution of the invention, what the waveform sliding slot was mounted on tunnel or so hole wall keeps away Ren Dong
Top, and be fixedly connected with tunnel wall, the binocular CCD camera is fixedly connected with sliding slot by camera cushion cap, described specific
Shooting angle can be controlled according to binocular CCD camera position and rotatable camera cushion cap.
For the present invention compared with traditional artificial hand-held detection device method, intelligent measurement can be realized comprehensively by having, and not influence tunnel
Road operation, the advantages such as space-time expending is strong, degree of intelligence is high, precision is high, operability is excellent, therefore can be widely used in tunnel
In hole week transformation safe monitoring and warning.
