Description
Technical field
The present invention relates to a kind of train detection systems, specifically, relate to a kind of safe train operation monitoring system.
Background technology
Train is a kind of trip mode that people's trip most often selects, and in order to ensure the smooth trip of train, train is being transported
It needs to monitor the track in front of train in real time during row, judges whether there is the early summer of foreign body intrusion.Existing train operation inspection
Examining system is mostly ground detection or train detection, and the front track information that detection device single in this way causes train to obtain is not smart enough
Really.
In order to solve the problems, such as present on, people are seeking a kind of ideal technical solution always.
Invention content
The purpose of the present invention is in view of the deficiencies of the prior art, system is monitored so as to provide a kind of safe train operation.
To achieve these goals, the technical solution adopted in the present invention is：A kind of safe train operation monitors system, packet

Based on above-mentioned, second video acquisition module is wide-angle camera.
The present invention has prominent substantive distinguishing features and significant progress compared with the prior art, and specifically, the present invention is logical
It crosses and combines ground detection and train detection, expand the visual field of safe train operation detection, reduce because blind area is led
Train operation is caused the generation of accident phenomenon occur；In addition thermal camera and visible light camera are combined, improves figure
As the unicity of acquisition, the adaptability of safe train operation detection is improved.
Description of the drawings
Fig. 1 is the principle of the present invention block diagram.
Specific embodiment
Below by specific embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of safe train operation monitoring system, including on-vehicle host, Vehicular video acquisition module and ground
Plane video acquisition module, the on-vehicle host connect respectively with the Vehicular video acquisition module and the ground video acquisition module
It connects.
The Vehicular video acquisition module is divided into the first video acquisition module and the second video acquisition module, wherein, it is described
First video acquisition module is arranged on the top of train head, and the image for acquiring the running environment in front of train in real time with high visual angle is believed
Breath；Second video acquisition module is arranged on train bottom, for acquiring the running environment in front of train in real time with low vision
Image information.
Preferably, first video acquisition module is standard focal length video camera, and second video acquisition module is wide
Angle video camera, the area of visual field of the standard focal length camera are the region in front of train, the field of vision of the wide angle cameras
Domain is the region in front of train, and includes the area of visual field of the standard focal length camera.Due to the standard focal length camera
The high resolution of captured picture and the area of visual field of the wide angle cameras is wider, therefore by first video acquisition module
Image and the image of second video acquisition module acquisition merged, the field of view range formed is wide and clarity
It is high.
The ground video acquisition module is set along train operation orbit distribution, for acquiring in real time by train operation track
Image information.
Preferably, first video acquisition module, the second video acquisition module are visible light camera, and the ground regards
Frequency acquisition module is thermal camera；When illumination visibility is preferable, using based on train video acquisition module, ground video adopts
Collect the pattern supplemented by module, the picture of the ground video acquisition module acquisition is mainly used as video source modeling processing；When illumination energy
When degree of opinion is poor, automatically switch to based on ground video acquisition module, the pattern supplemented by train video acquisition module, the train
The picture of video acquisition module acquisition is mainly used as video source modeling processing；Mode in this way may insure safe train operation
Monitoring system obtains running environment in front of clear complete train in real time.
The on-vehicle host includes image co-registration module, picture recognition module and control module, described image Fusion Module
The image of first video acquisition module, second video acquisition module and the ground video acquisition module acquisition is believed
Breath is merged, and generates train operation environment complete image；Described image identification module judges that the train operation environment is complete
With the presence or absence of abnormal object in image, and extract the profile of the abnormal object；The control module is according to the abnormal object
Profile judge abnormal object profile height or it is wide whether be more than default abnormal object high or wide threshold value, when beyond when, then
The control module judges that the abnormal object can influence train operation and alarm.
Described image Fusion Module is by first video acquisition module, second video acquisition module and the ground
The method of image information fusion of video acquisition module acquisition is：
Multi-resolution decomposition is carried out, then carry out multi-direction point in each resolution ratio figure layer to source images based on contourlet transform method
Solution, then carries out color notation conversion space, L α β is gone to from RGB, pair can in the characteristic for the triple channel independence for combining L α β color spaces
See that light and infrared light are merged.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific embodiment of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover in the claimed technical solution range of the present invention.
