Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.It should be appreciated that specific embodiment described herein is only used to explain this practicality
It is new, it is not used to limit the utility model.
Embodiment one
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of dress of the online detection lorry superelevation of noncontact
Put, including：Infrared laser (can hereinafter be represented with M1 with figure), web camera (hereinafter can use M2 with figure
Represent) and image processor (can hereinafter be represented with M3 with figure), the infrared laser and the network shooting unit
Into detection module, the detection module is arranged on the portal frame above track, and each described track top corresponds to installs one
The group detection module (can hereinafter be represented with Mx with figure), the laser of infrared laser transmitting is on the projection surface
Subpoint can be imaged in the web camera, form imaging point, and the perspective plane includes road surface, limit for height face and lorry most
Face high, the corresponding imaging point in highest face on the road surface, limit for height face and lorry is respectively a points, b points and c points, the network shooting
Machine is connected with described image processor data, and described image processor can carry out the contrast of a points, b points and c points position, and according to
Comparing result judge lorry whether superelevation.
Using said structure judge lorry whether the operation principle of superelevation can be as shown in Figure 3.
M1 the subpoint A on road surface, the imaging point a on video camera Sensor target surfaces, near video camera Sensor's
Target surface edge.When the laser projection face of M1 transmittings rises, image space of the laser projection point on video camera Sensor target surfaces
Also can therewith to target surface centre position move, be gradually distance from imaging point a, when perspective plane progressively on move on to limit for height position when, M1 exists
The subpoint B on limit for height position perspective plane, the imaging point b on video camera Sensor target surfaces, if perspective plane is further up, reaches
To ultrahigh wagon height when, M1 the perspective plane of this lorry superelevation position subpoint C, in video camera Sensor targets
Imaging point c, c on face understand setover b a further away from each other.In actual applications, if subpoint setover b, can sentence
It is set to lorry superelevation.
A kind of device of the online detection lorry superelevation of noncontact that the utility model embodiment is provided, it uses the process can
To comprise the following steps：
S1, demarcates subpoint of the laser of each infrared laser transmitting on limit for height face and road surface in the net
Imaging point b, a in network video camera, and the position of the position of each b and a is stored in described image processor；
S2, the video image that web camera described in described image processor real-time reception sends, and to the video figure
As carrying out Treatment Analysis, the laser of each infrared laser transmitting corresponding to the web camera is found in lorry
Highest face subpoint imaging point c；
S3, judge point c position whether the position of point of distance a, and surmounted the position of point b, if it is, thinking lorry
Superelevation, otherwise it is assumed that the non-superelevation of lorry or be not lorry.
Described image processor (M3), can select common industrial control type computer, is connected with multiple M2 by network.In peace
After dress during system debug, the limit for height position that can demarcate each M1 projects into picture point b, and the position of each b is deposited in M3
Storage record.The video image that M3 real-time receptions M2 sends, Treatment Analysis are carried out to image, are found first each corresponding to M2
The subpoint of individual M1 actual imaging position in the picture, then judges whether this position has surmounted the limit for height position for pre-saving again
The image space b of subpoint is put, if surmounted, just just in the vehicle super-high of this lanes, now M3 can be by network for explanation
Given a warning message to other related systems, notify that other systems are further processed.The explanation of above operation principle can be such as Fig. 5
It is shown.
In the present embodiment, after S3, step can also be included：Whether between points a andb to judge the position of point c, and occur
It is mobile, if it is, thinking there are vehicle or other objects to pass through on track.
The attainable function of the above method is：If the vehicle of traveling does not have superelevation, vehicle can also cause M1 when passing through
The change in location of the subpoint of the laser of transmitting imaging point in the picture, can be judged on track according to this change whether
There is vehicle to pass through, this information can be sent to other interconnected systems by M3, can be used as the work(such as vehicle flowrate, bayonet socket video capture
Energy.
Therefore, using the device of the online detection lorry superelevation of noncontact provided in an embodiment of the present invention, can be by sentencing
Whether the position of imaging point of subpoint of the laser of disconnected infrared laser transmitting on lorry highest face in web camera
The laser demarcated is crossed in the position of the imaging point of the subpoint in web camera in limit for height face, has completed what is travelled on road
Vehicle whether there is the detection of superelevation situation, not only efficient and convenient, and completely without manual intervention, safe, efficiency high.
Detect that module includes multiple infrared lasers in a preferred embodiment of the present utility model, described in every group
With a web camera.
In said structure, using multiple M1 and M2, a detection module Mx is constituted, device can be further enhanced
Reliability, such as, in automotive run-off-road, when diatom of delaying unloading is travelled, can also carry out effective reliable detection.
In a preferred embodiment of the present utility model, the multiple described infrared laser in module is detected described in every group
Device is uniformly arranged on the portal frame above the corresponding track.
During practical application, the M1 in Mx be evenly distributed on detection track top, so no matter vehicle traveling where,
Can effective detection.
In the utility model embodiment, as shown in figure 4, face and perspective plane where the laser of infrared laser transmitting
Between angle be acute angle, the angle between the imaging surface of the web camera and the perspective plane is right angle.
In the present embodiment, the angle between face and perspective plane where the laser of the infrared laser transmitting can be with 60 °
~80 °.
The angle between face and perspective plane where the laser of the infrared laser transmitting is smaller, then in different height
On perspective plane, the distance of imaging point of the laser projection point in video camera is bigger, more easily makes a distinction, but if angle mistake
Small, then subpoint will exceed the areas imaging of video camera, be highly 6M~7M in portal frame through measuring and calculating and actual verification, take the photograph
When camera uses 12mm camera lenses, this angle is set to 60 °~80 ° and is advisable.
In a preferred embodiment of the present utility model, the infrared laser uses the laser of point source of light, described
Infrared filter is provided with the camera lens of web camera.
In said structure, M1 makes the projection on the projection surface of the laser of transmitting be in point-like using the laser of point source of light.
Infrared fileter is installed additional before the camera lens of M2, the infrared laser for enabling M1 to launch passes through optical filter.Other are visible
Light can not be by optical filter, so in the imaging of M2, and only M1 subpoints on the projection surface, other iconic elements are very weak,
Easily carry out effectively filtering and recognizing.
