Description
Technical field
The present invention relates to a kind of warning device, specially a kind of trafficability warning device based on much information fusion
And its method, belong to the driving ancillary technique field of intelligent driving control.
Background technique
In commercial vehicle field, vehicle often requires to can not be successfully through running section due to limitations such as limit for height, freight weight limits, due to
The carelessness of driver causes the event for damaging building even more commonplace；More there is the driving technology reason for being limited to driver,
The barriers such as bridge opening, portal frame for indefinite height, can not confirm its passability, influence the timeliness of traffic safety and driving
Property.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of trafficabilities based on much information fusion
Warning device is judged, to assist whether driver evaluation can be alerted by the section when that can not pass through section.
To realize the above technical purpose, the technical scheme is that the trafficability report based on much information fusion
Alarm device, which is characterized in that including the camera being arranged on vehicle front windshield glass, the controller being connect with the camera
And the alarm connecting with the controller, the controller are connect with vehicular map, trailer-mounted radar respectively.
Further, the alarm include loudspeaker and warning display interface, the loudspeaker and warning display interface
It is connect with controller.
Further, image processing module is integrated on the camera.
In order to further realize the above technical purpose, the present invention also proposes the trafficability report merged based on much information
Alarm method, which comprises the steps of:
Step 1 works as vehicle in the process of moving, and the camera being placed on vehicle front windshield glass obtains traffic information, through scheming
After processing module processing, controller is sent to after extracting characteristic feature；
Controller described in step 2 downloads vehicular map, obtains the section limit for height, freight weight limit information, in conjunction with vehicle oneself height and
Weight judges whether that the section can be passed through；
If step 3 cannot control alarm equipment alarm by the section, controller；
Camera information judges whether there is barrier to controller described in step 4 based on the received, vehicle-mounted if there is barrier
The dimension information of detections of radar barrier, and it is sent to controller；
Controller described in step 5 passes through the information effective integration of trailer-mounted radar and camera, realizes the size to obstacle target
Accurately measure, thus calculate vehicle can travel region range；
Step 6 judges whether vehicle can pass through in conjunction with vehicle oneself height, weight information；
If step 7 can not by when, controller control alarm equipment alarm.
Further, the traffic information in the step 1 includes road sign information, contains limit for height, freight weight limit information.
Further, the alarm equipment alarm information includes that warning display interface shows early warning language and loudspeaker casting
Early warning.
Compared with prior art, the invention has the following advantages that
1) speed limit, the limit for height information of present invention fusion map, makes up camera in sign board identification process by environmental factor shadow
The defect for ringing accuracy rate decline, improves the alarm accuracy rate of system；
2) present invention is merged by camera and radar (millimetre-wave radar) information, the trafficability judgment method of realization,
Vehicle driving efficiency can be effectively improved, reduction scrapes, hits risk, improves vehicle driving safety.
Detailed description of the invention
Fig. 1 is structural schematic block diagram of the invention.
Appended drawing reference: 1, camera；12, image processing module；2, controller；3, alarm；31, loudspeaker；32, it warns
Display interface；4, vehicular map and 5, trailer-mounted radar.
Specific embodiment
Below with reference to specific drawings and examples, the invention will be further described.
As shown in Fig. 1, the trafficability warning device based on much information fusion in the present embodiment 1, including setting
Camera 1, the controller 2 being connect with the camera 1 on vehicle front windshield glass and the report being connect with the controller 2
Alert device 3, the controller 2 are connect with vehicular map 4, trailer-mounted radar 5 respectively.
The alarm 3 includes loudspeaker 31 and warning display interface 32, the loudspeaker 31 and warning display interface 32
It is connect with controller 2.
Image processing module 12 is integrated on the camera 1.
The trafficability alarm method based on much information fusion of embodiment as above, includes the following steps:
Step 1 works as vehicle in the process of moving, and the camera 1 being placed on vehicle front windshield glass obtains traffic information, through scheming
After handling as processing module 12, controller 2 is sent to after extracting characteristic feature；
The traffic information includes road sign information, contains limit for height, freight weight limit information；
Controller 2 described in step 2 downloads vehicular map 4, the section limit for height, freight weight limit information is obtained, in conjunction with vehicle oneself height
And weight, judge whether that the section can be passed through；
If step 3 cannot be controlled alarm 3 and be alarmed by the section, controller 2；
1 information of camera judges whether there is barrier to controller 2 described in step 4 based on the received, if there is barrier, vehicle
It carries radar 5 and detects the dimension information of barrier, and be sent to controller 2；
Controller 2 described in step 5 passes through the information effective integration of trailer-mounted radar 5 and camera 1, realizes to obstacle target
Size accurately measures, so that calculating vehicle can travel the range in region；
Step 6 judges whether vehicle can pass through in conjunction with vehicle oneself height, weight information；
If step 7 can not by when, controller 2 control alarm 3 alarm；
The model AR0132 of camera 1 in the present embodiment 1, the model SPC5604P of controller 2.
Camera 1 of the invention identifies road sign information, containing limit for height, freight weight limit etc., and with the section in vehicular map 4
Limit for height, freight weight limit information are merged, and issue alarm when being unable to satisfy passability requirement in conjunction with vehicle oneself height and weight
Information；
Camera 1 of the invention carries out identification extraction to obstacle information within the vision, passes through trailer-mounted radar 5 and camera
