Description
Technical field
A kind of drink-driving behavior the present invention relates to field of traffic control more particularly to highway based on video analysis
Method for early warning.
Background technique
" People's Republic of China Road Traffic Safety Law " Article 22 the regulation, " spirit for national regulatory of drinking, take
Perhaps narcotics perhaps has the disease for interfering safe driving motor vehicle or defatigation to influence safe driving to drug, no
Obtain operating motor vehicles."
In fact drinking drive motor vehicle illegal incidents are commonplace, and drunk driving does not only result in vehicle, cargo and the life of driver and passenger
Life and property loss also cause road, bridge, tunnel, house etc. to build and build upper attached all kinds of management equipments, mark
The damage of label.Highway is different from urban road, because of its closure and the needs continuously driven, halfway without law enforcement people
Member carries out drunk driving behavioral value, and the personnel that cause much to drink cherish idea of leaving things to chance, drives into highway after drinking.And highway
Because car speed is fast, vehicle amount is big, traffic accident consequence occurs usually than more serious.Traffic accident would generally be to entire road
Traffic produce and seriously affect, road can not be restored in the short time, and be easy to cause second accident.
Freeway management at this stage is mainly that monitoring center monitor is managed by video, because of video equipment number
Measure more, the work of monitor is laid particular emphasis on to dispatch deal after the accident, lacks effectively observation to vehicle drive behavior.It can
To say that existing control of traffic and road means have management blind area for drinking drive behavior, it can not find that in time driving behavior is different
Normal vehicle, can not predict driving behavior exception vehicle i.e. by bring harm, can not drink to highway has been swarmed into
Driver carries out any management.Traffic accident vehicle can be just only arrested after accident generation, behaviour post-processing of going forward side by side.It is this
Processing means can not safeguard road traffic order, it is difficult to retrieve property caused by drunk driving vehicle and human loss.
Summary of the invention
A kind of drink-driving behavior method for early warning the object of the present invention is to provide highway based on video analysis is realized
Road order is safeguarded in discovery, early warning, guidance to highway drunk driving vehicle is swarmed into the maximum extent, ensures that the people are raw
Order property and with freeway infrastructure equipment safety.
To achieve the goals above, the technical scheme is that
A kind of drink-driving behavior method for early warning of the highway based on video analysis, which comprises the following steps:
Step S1) trajectory computation step, shoot by way of vehicle, the driving path of vehicle is obtained, to vehicle in origin and destination path
On driving behavior carry out irrelevance signature analysis, determine vehicle whether there is drink-driving, if so, carry out step S2, if
It is no, then return step S1；
Step S2) path monitoring step, the driving path of doubtful drink-driving vehicle is monitored, generates the driving information of the vehicle simultaneously
Alarm；
Step S3) drunk driving judgment step, doubtful alarm signal is received, the vehicle drive information is received, calls vehicle running path
Upper subsequent video camera persistently shoots the vehicle, is confirmed again according to the irrelevance signature analysis in step S1, is mentioned after confirmation
Artificial analysis, the manual confirmation vehicle whether drunk driving, if so, carrying out step S4；If it is not, then stopping tracking the vehicle, return
It is back to step S1；
Step S4) monitoring tracking step, scheduling high-speed highway law enfrocement official and road administration inspection inspection personnel supervise the vehicle
Control；
Step S5) rale violation warnings step, it alerts the vehicle and stops drunk driving behavior, sails out of highway into service area or nearby,
And other drivers provide warning information near the vehicle；
Step S6) information storing step, the driving information of the vehicle is individually stored.
Further, the trajectory computation step following steps:
Step S101) background image is selected from sequence of video images, background model is established by ViBe algorithm；
Step S102) it is directed to each vehicle for entering shooting area, it is adjacent in sequence of video images by frame differential method
Two frames make calculus of differences, and previous frame image is pk-1 (x, y), and current frame image is pk (x, y)；
Step S103) it judges whether there is vehicle and drives into detection zone, if so, jump procedure S104；If it is not, then jump procedure
S102；
Step S104) calculate present frame and background frames poor FD (x, y), complete target is extracted from image；Calculate preceding 1 frame
With the poor FG (x, y) of background frames, the variable quantity of target is obtained；
Step S105) intersection of asking FD (x, y) Yu FG (x, y), obtain the coarse moving region image of moving target；
Step S106) through mathematical morphological operation, moving region is closed, is continuous, is complete, removes the noise in background；
Step S107) judge whether vehicle sails out of shooting area, if so, jump procedure S108；If it is not, then return step
S105；
Step S108) for each vehicle into shooting area, it calculates inlet point position and leaves a position straight line path；
Step S109) it calculates separately in each frame image, the irrelevance between a straight line is left in vehicle location and entrance；
Step S110) judge whether appearance position positive deviation and negative bias reach three times vehicle from number simultaneously, if so, the vehicle
For doubtful drink-driving vehicle；If it is not, then the vehicle is not drink-driving vehicle.
Further, the driving information includes the short-sighted frequency of vehicle behavior and vehicle closeup photograph.
The present invention has the advantages that
1) vehicle driving behavior is judged using frame differential method to vehicle driving trace, the algorithm is without parsing picture in its entirety, only
Difference between analysis picture, automatically analyzes the driving behavior of vehicle on highway driver, and analysis process is reliable rapidly；
2) it is freeway management person's early warning dangerous driving behavior vehicle, realizes the fine-grained management to vehicle on highway, mention
High Operation and Management of Expressway is horizontal；
3) dangerous driving behavior vehicle is intervened in time, other drivers of the early warning vehicle periphery avoid highway traffic accident
With great life and property loss.
