Detailed description of the invention
In order to deepen the understanding of the present invention, the present invention is further described with embodiment below in conjunction with the accompanying drawings, this enforcement
Example is only used for explaining the present invention, does not constitute protection scope of the present invention and limits.
For current safe driving, driver in drunk driving, fatigue driving, make a phone call, in the case of insobriety
Driving is fraught with risks, and is susceptible to vehicle accident.At present, anti-fatigue-driving technology based on human facial expression recognition has fuzzy
Property, uncertainty, such as patent 201310209728, and can not accurately analyze make a phone call, drunk driving etc. changes phase with facial expression
The dangerous driving behavior that closing property is weak；Safe driving based on steering wheel pressure transducer is set up, such as patent 201410397767, then
Driver's both hands attitudes vibration cannot be detected, thus miss and the driving of long-time fixed pose, doubtful doze behavior are divided
Analysis alarm.
In order to solve above-mentioned technical problem, the present invention provides a kind of hands based on binocular vision to detect equipment, including first
Photographic head, second camera, arithmetic unit and local alarm device, wherein, arithmetic unit Real-time Collection the first photographic head and the
The video image of two photographic head, carries out dangerous driving behavior and comprehensively analyzes, and when finding dangerous driving behavior, is reported by this locality
Alarm device performs local actuation of an alarm；Data recording equipment storage arithmetic unit collection is from the first photographic head and second camera
Real time video image, as the conclusive evidence of dangerous driving behavior, thus reaches accurately to analyze and record various dangerous driving row
For, real-time prompting driver and surrounding vehicles the purpose automatically performing safety measure.
To this end, provide a kind of hands based on binocular vision to detect equipment, as it is shown in figure 1, include the first photographic head 1, second
Regarding of photographic head 2, arithmetic unit 3 and local alarm device 4, arithmetic unit Real-time Collection the first photographic head 1 and second camera 2
Frequently image, carries out dangerous driving behavior and comprehensively analyzes, and when finding dangerous driving behavior, performs basis by local alarm device
Ground actuation of an alarm, wherein, dangerous driving behavior analysis is as in figure 2 it is shown, its step is as follows:
A) image common-denominator target extracts, and such as the S1 of Fig. 2, to the first photographic head 1 and the real time video image of second camera 2, divides
Take steering wheel therein and both hands target indescribably, and the relative position of calculated direction dish and both hands target, angle and distance data；
The premise of this step is the relative position relation of known photographic head and steering wheel, owing to photographic head is fixedly mounted on steering wheel
Front, this relative position relation can described hands detection equipment install time be determined；
The Objective extraction characteristics of image of steering wheel is its shape and color, and the Objective extraction characteristics of image of both hands and arm
Being its shape, profile and motion feature, this motion feature can solve according to image dynamic change characterization；
According to single photographic head, both hands and the steering wheel position relationship on horizontal plane can only be drawn, including the phase of the two
To position, angle and distance data, but cannot definitely learn that both hands are whether in steering wheel plane.
B) two-hand positions relation calculates, such as the S2 of Fig. 2, in conjunction with from the first photographic head 1 and the direction of second camera 2
The relative position of dish and both hands target, angle and distance data, perform data correction and fusion, obtain both hands relative to steering wheel
Exact posture and positional information；
This step can calculate both hands and the vertical height of steering wheel plane and horizontal range, and the real-time attitude of arm, as
In conjunction with the most dynamically analyzing, then can analyze driver and keep the duration of certain vehicle driving posture.According to above-mentioned information, can be
Next step driving behavior analysis provides abundant and sufficiently exact attitude and positional information.
C) driving behavior data analysis, such as the S3 of Fig. 2, according to the both hands exact posture calculated and positional information, analyzes
Drunk driving therein, fatigue driving, make a phone call, the dangerous driving behavior such as insobriety.
Both hands are relative to the attitude of steering wheel and positional information, including both hands and the vertical height of steering wheel plane, level
Distance and the real-time attitude of arm, corresponding to drunk driving, fatigue driving, make a phone call, the different dangerous driving such as insobriety
Behavior, such as: drunk driving there will be significantly abnormal arm action, makes a phone call, there will be one hand and hold up steering wheel, fatigue driving meeting
Occur keeping fixing vehicle driving posture for a long time.
Local actuation of an alarm includes that the sound and light alarm outside Che Nei and car, reduction of speed travel and force to stop.Acousto-optic report in car
Alert prompting driver safety is driven, and car outer sound and light alarm prompting surrounding vehicles is dodged in time.When extremely hazardous driving row occurs
For time, reduction of speed travel even force parking can avoid security incident in time.
A kind of hands based on binocular vision detection equipment also includes data recording equipment 5, and it is used for storing arithmetic unit 3 and adopts
Collection is from the first photographic head 1 and the real time video image of second camera 2, and this is as the conclusive evidence of dangerous driving behavior.
A kind of hands based on binocular vision detection equipment also includes data remote transmitting device 6, arithmetic unit 3 analysis is drawn
Dangerous driving behavior data, and data recording equipment 5 storage vedio data be sent to remote data management center.
What the present invention can reach has the technical effect that
Real-time Collection the first photographic head of the present invention and the video image of second camera, and through image common-denominator target extract, double
Hand position relation calculates, and performs data correction and fusion, obtains both hands relative to the exact posture of steering wheel and positional information, picks
Except the uncertainty in video image identification and fuzzy factors, improve and analyze and the accuracy of hazardous act warning；This
Bright when finding dangerous driving behavior, perform local actuation of an alarm by local alarm device, driver safety can be reminded to drive,
Remind surrounding vehicles to dodge and can automatically perform reduction of speed in time to travel, force the safety measures such as parking；Data recording equipment is real-time
Store by arithmetic unit collection from the first photographic head and the real time video image of second camera, as dangerous driving behavior really
Cut evidence.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto, the ordinary skill people of this area
Member, easily according to above-described embodiment, understands the spirit of the present invention, and makes different amplifications and change, but as long as without departing from this
The spirit of invention, the most within the scope of the present invention.
