Concrete condition understands the concrete meaning of above-mentioned term.
As shown in Figure 1, the present invention provides a kind of track clearance intrusion detection method compared based on image,
During train driving, real-time acquisition trajectory traffic image.The rail traffic road conditions image includes tunnel
Cross-sectional image and/or train front track image.
When the train is located at station A, which sends a upper station for train acquisition to the rail of station A to station A
Road traffic image.The upward station station A sends the rail traffic road conditions image that station A is received from the train, and will
Rail traffic road conditions reference picture of the rail traffic road conditions image as next train from a upper station to station A.
Station A sends the rail traffic road conditions reference for the station A to next station station B that station A is stored to current train
Image；The rail traffic road conditions reference picture of the station A to station B of station A storage comes from station B, is sent by previous column vehicle
Station B is given, then station A, i.e. the rail traffic road conditions reference picture that station A is sent to current train are sent to by station B
It is the rail traffic road conditions reference picture of the newest station A to station B stored in the A of station.
Current train is by the rail traffic road conditions reference picture of received station A to station B and the train from station A
The rail traffic road conditions image acquired in real time into the driving process of station B is compared frame by frame, and detection track is with the presence or absence of limit
Boundary's invasion provides operator alert if when having limit invasion danger in discovery image or other are endangered in real time.
When station A is initiating station, the not upward station station A sends rail traffic road conditions image.
When station A is terminus, station A does not send rail traffic road conditions reference picture to train.
In order to reduce the burden of memory, this method has preferred embodiment: when train operation is to station B, when station A is received
After the rail traffic road conditions image of the station A to station B sent to station B, directly formerly stored with image covering station A
The rail traffic road conditions reference picture of station A to station B.
Another preferred embodiment of this method: each station is by the rail traffic at a received upper station to current station
Road conditions image is sent to image processing server, and described image processing server divides the image of same route different moments
Analysis processing, obtains the state variation tendency of each section of route, when as found to have slowly varying potential limit invasion danger in image
It gives a warning.Such as in the present solution, rail traffic road conditions of the station A to the upper station of image processing server transmission to station A
Image, station B send the rail traffic road conditions image of station A to station B to image processing server.
Corresponding Image Acquisition, image comparison, figure are carried out in the same manner described above between other stations, station and station
As transmission.
The application also proposed a kind of embodiment of track clearance invasion detecting device, the track clearance invasion detecting device
Including be installed on train image detecting element, be installed on part or all of station with described image detection unit channel radio
Believe the station image management unit of connection, is communicated to connect between the adjacent station image management unit, further include at image
Server is managed, described image processing server and each station image management unit communicate to connect.
As shown in Fig. 2, described image detection unit includes image capture module, processing module and memory module, image is adopted
Collection module includes camera model and light compensating lamp, and light compensating lamp is that camera model acquires image light filling, and camera model and processing module connect
It connects, described image acquisition module acquisition trajectory traffic image, the memory module stores current station to next station
The rail traffic road conditions image of rail traffic road conditions reference picture and the acquisition of described image acquisition module.
When it is implemented, processing module and memory module can be integrated in an Embedded Image Processing System, this is embedded
Image processing system includes can also integrated image transmission module.
Station image management unit includes another Embedded Image Processing System, wherein the Embedded Image Processing System packet
Include image transmitting, image stores two sub-function modules.
As shown in Figure 1, train gets to the station when A, the processing module of the image detecting element on the train is to wirelessly communicate
Mode from the station image management unit of station A downloading station A to station B rail traffic road conditions reference picture and be stored in
In memory module；A upper station for image capture module acquisition is also uploaded to the rail traffic road conditions image between the A of station to vehicle
It stands in the station image management unit of A.After the station image management unit of station A gets current train upload data, to have
The mode of line or wireless communication transmits it to the station image management unit at previous station, the image data that can also will acquire
It is transmitted to image processing server.
When the train, which sails out of station A, drives towards station B, according to it is set rule shoot vehicle front image, and frame by frame with obtain
The rail traffic road conditions reference picture of the station A to station B taken is compared in real time, as found there is limit invasion danger in image
Or other then pass through alarm unit when endangering and provide operator alert in real time.
When the train gets to the station B, the processing module of the image detecting element on the train is in a manner of wirelessly communicating
Station B is downloaded to the rail traffic road conditions reference picture at next station from the station image management unit of station B and is stored in
It stores up in module；The rail traffic road conditions image between the station A to station B of image capture module acquisition is also uploaded to station B's
In the image management unit of station；The station image management unit of station B is got after current train uploads data, with wired or
The mode of wireless communication transmits it to the station image management unit of station A, and the image data that can also will acquire is transmitted to figure
As processing server.
Other stations, station carry out corresponding Image Acquisition, image comparison, image in the same manner described above with station and pass
It is defeated.
While image processing server obtains the realtime graphic of station image management unit at each station, not to same section
Image data in the same time is analyzed and processed, and obtains the state variation tendency of each section of route, as found there is slow change in image
The potential limit invasion danger changed or other provide warning when endangering.
Method used by image comparison, analysis involved in the application is all made of existing image analysis processing side
Method is no longer described in detail in the application.
