Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme of the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, all other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belong to the scope that the present invention protects.
The object of the invention; Be to provide a kind of crossing traffic early warning system; Can be in the crossing, people's cars such as turning and corner are crowded or sight line not Jia Chu detect whether the distance in workshop is safe range; And sending a car or the pedestrian produces alarm when getting in the fence coverage, to driver and pedestrian caution is provided.
Please refer to the 1st figure, it is the framework calcspar according to the crossing traffic early warning system of one embodiment of the invention.The crossing traffic early warning system 100 of one embodiment of the invention can be installed in road corner, turning or crossing etc. and locate, and includes: image acquiring unit 110, arithmetic element 120 and caution unit 130.
Crossing traffic early warning system 100 comprises at least one image acquiring unit 110, and image acquiring unit 110 can comprise Charged Coupled Device (CCD), complementary metal oxide layer semiconductor (CMOS) or network camera (IP Camera) one of them or its combination in any; Image acquiring unit 110 also can be a concealed camera.In the present embodiment; Image acquiring unit 110 is done single or multidirectional shooting with video-corder in places such as road corners; Obtain the image in the guarded region, and produce signal of video signal 111 (signal of video signal 111 can be digital image signal or analog image signal), the signal of video signal 111 that will obtain continuously again sends connected arithmetic element 120 to; Wherein, image acquiring unit 110 can also include other unit between the two with arithmetic element 120.Guarded region can comprise road junction, L shaped road corner, T shape road corner or circular arc road bend one of them or its combination in any.
The information of vehicles that arithmetic element 120 is detected comprises car speed for example (according to calculating through the time that distance spent between two preset fixed points), vehicle direct of travel (calculating institute through 2 vector) or vehicle kenel (according to image size, characteristic and profile), and the vehicle kenel for example comprises visible vehicle class on the present road such as bicycle, locomotive, minibus, medium truck, large truck, rig; And the pedestrian information that arithmetic element 120 is detected comprises pedestrian's speed for example (according to calculating through the time that distance spent between two preset fixed points), pedestrian's direct of travel (calculate through 2 vector) or pedestrian's kenel (according to image size, characteristic, action and profile); And that pedestrian's kenel comprises is for example single, 5 people with interior or 10 people with different number crowds such as interior; Or the pedestrian of slow in action inconvenience, or pupil of short and small stature etc.
For example; Setting through guarded region internal trigger line; Or according to the car speed or the pedestrian's speed that get in the guarded region; Arithmetic element 120 also can calculate the distance and the time of vehicles or pedestrians to road junction, L shaped road corner, T shape road corner or circular arc road bend, so that send clearly caution ahead of time.
In case arithmetic element 120 has detected vehicle in guarded region after analyzing, simultaneously further with reference to car speed, vehicle direct of travel and vehicle kenel, and produce control signal 121, and transmit control signal 121 and give connected caution unit 130; Or arithmetic element 120 has detected the pedestrian in guarded region after analyzing; Simultaneously further with reference to pedestrian's speed, pedestrian's direct of travel and pedestrian's kenel; And generation control signal 121; And transmit control signal 121 and give connected caution unit 130, wherein, arithmetic element 120 and caution unit 130 can also include other unit between the two.
In one embodiment of the invention, according to predefined segmentation condition, drive caution unit 130 by control signal 121 and send caution 131, when for example being positioned at beyond the guarded region when sending a car, caution unit 130 does not produce caution 131; Come in the guarded region when sending a car; Caution unit 130 produces sound caution; And when vehicle during more near guarded region core positions such as road junction, L shaped road corner, T shape road corner or circular arc road bends, the caution sound that caution unit 130 produces is rapid more.Or vehicle is when at a high speed getting in the guarded region, and captions will show " send a car at a high speed, please step up vigilance, still have 220 meters apart from the crossing, arrive the crossing in 5 seconds ", and the voice broadcast service of arranging in pairs or groups simultaneously, with prompting pedestrian and vehicle drive.Or arithmetic element 120 has detected the vehicle reverse driving when entering in the guarded region, will flash.Maybe ought detect the vehicle kenel is that the big truck of tonnage enters in the guarded region; And during more near crossing, turning or corner, the frequency that the voice of " truck is approaching, please step up vigilance " send will be high more; Along with truck breaks away from guarded region gradually, the audible frequency of voice also will be by height gradually to not having.Or arithmetic element 120 has detected pokesy pedestrian or crowd when entering in the guarded region; The LED film titler will show " pedestrian is crossed the crossing; still have 10 meters apart from the corner; 0.27 kilometer of speed per hour, estimates that arrive at the corner still had 10 times in second, and vehicle please slow down " and collocation caution flashlamp bright lamp that glimmers.
According to another embodiment of the present invention, above-mentioned crossing traffic early warning system 100 also comprises storage element 140, is connected with arithmetic element 120, and wherein, storage element 140 and arithmetic element 120 can also include other unit between the two.Storage element 140 is in order to store signal of video signal 111; Further; Storage element 140 can only store the signal of video signal 111 when finding to have people or car to occur after process arithmetic element 120 is analyzed; Can reach the benefit of saving the storage area, and have access to incident image at that time after supplying to get into an accident, investigate thoroughly traffic accident responsibility with reduction site of the accident situation.
According to still another embodiment of the invention, above-mentioned crossing traffic early warning system 100 also comprises light auxiliary unit 150, is connected in image acquiring unit 110; Light auxiliary unit 150 is carried out obtaining of image with auxiliary image acquiring unit 110, particularly under the environment condition of poor in order to luminous; For example during night; The image quality that image acquiring unit 110 is taken can decline to a great extent, and the bad system that will let of discrimination power can't judge correct result, and this moment, light auxiliary unit 150 was promptly in order to overcome the atrocious weather situation; Increase discrimination power, system can correctly be judged.
The 2nd figure is the synoptic diagram according to the crossing traffic early warning system of the part unit that is arranged at L shaped road of one embodiment of the invention.Shown in the 2nd figure; In the corner of L shaped road 200, be provided with image acquiring unit 210, in order to obtain the image in the guarded region 220 (comprising L shaped road corner); When vehicle 240 by left; Or pedestrian 260 is by right-hand and enter in the guarded region 220, and detected information of vehicles 250 (comprising car speed, vehicle direct of travel and vehicle kenel) or pedestrian information 270 is when (comprising pedestrian's speed, pedestrian's direct of travel and pedestrian's kenel), and caution unit 230 will send caution; For example show captions and sound indication " please note left send a car fast ", or " please noting right-hand pedestrian ".
