Abstract
A method for automatic determining an accident and giving off alarm based on monitoring video comprises the steps of carrying out full-length seamless monitoring on a highway through a camera distribution network on the highway and uploading the monitored video data to a hard disk video recorder, a background system carrying out primary identification on the monitoring video data uploaded, directly playing the monitoring video data on the monitoring screen of a highway administration if no accident is identified, giving off alarm to remind workers if an accident is identified, and the workers conducting secondary identification on the monitoring video data, for which an alarm is given off. In the method, automatic identification is added by using the background system before manually checking monitoring video, thereby improving highway accident discovery probability and accuracy. Accidents can be reported at the first time, thereby saving manual cost.
Description
Technical field
The present invention relates to a kind of traffic monitoring method, be specifically related to a kind of based on monitor video automatic decision accident and the method reported to the police.
Background technology
Fast development along with national economy, China Expressway mileage is continuously increased, what thus bring is be continuously increased vehicle accident quantity, after having an accident, how to be rapidly performed by processing, relevant administrative department is made that a lot of work, for instance increase photographic head density, increases staff and uninterruptedly real-time video is monitored for 24 hours.
Manually checking of main flow, video at least exists following point:
First being that human eye goes to check that video easily causes fatigue, thus after causing having an accident, monitoring personnel do not have the very first time to find, and easily causing the delay that accident finds, thus missing gold rescue time.Very many followed by highway photographic head quantity, if it is desired to one section of expressway is carried out the words of seamless monitoring, it is necessary to the personnel seeing video be also many especially, this has resulted in the rising of operation cost.
Summary of the invention
It is an object of the invention to: disclose a kind of based on monitor video automatic decision accident and the method reported to the police, it can be ensured that the very first time finds expressway traffic accident, reduces the loss of unnecessary personnel and property.
For solving the problems referred to above, the technical scheme that the present invention takes is: a kind of based on monitor video automatic decision accident and the method reported to the police, it is characterised in that to comprise the steps:
Step one, utilize the photographic head distributed network on highway that highway section carries out omnidistance seamless monitoring, and monitor video data are uploaded to DVR；
Step 2, utilize background system that the monitor video data above transmitted are carried out accident to screen for the first time, if the accident that do not screen out occurs, then directly these monitor video data are thrown on the monitoring screen of Speedway Control Broad；If the accident that screens out occurs, then send warning reminding staff；
The monitor video data sending warning reminding are carried out secondary examination by step 3, staff.
Utilize background system to realize automatically screening during first examination, save manpower and time, improve work efficiency.
Accident that monitor video data are carried out described in step 2 is screened for the first time and is specifically included following steps:
(1) image filtering system is run at background system, video information is cut into image one by one, then each two field picture is processed；
(2) when vehicle occurs in monitoring region, vehicle symbolization is become tetragon, if one of following state occurs, then regard as the accident that screens out and occur；If following state does not occur, then directly these monitor video data are thrown on the monitoring screen of Speedway Control Broad；
Distance between one, two adjacent quadrangular of state is less than 10 pixels, and doubtful is that two cars knock into the back or bump against；
State two, tetragon are not subjected to displacement at runway, for car, doubtful occur that accident or collision are stopped after knocking into the back；
State three, symbolization tetragon beyond normal car body size, doubtful for there is auto-ignition；
(3) it is thrown on the monitoring screen of Speedway Control Broad regarding as the monitor video data that the accident that screens out occurs, and carries out warning reminding staff and carry out secondary examination by generation flickering effect on giant-screen or by the speaker sound that sounds the alarm.
Distance between two adjacent quadrangular is less than 10 pixels, and this critical distance is determined by pixel and the image quality of photographic head, and value here is experiment value.
Image after filtration is screened through artificial secondary after showing, identifies the accident of generation really, reduces person works's amount and degree of accuracy is high.
Beneficial effect: the present invention utilizes background system automatically to discriminate method for distinguishing by adding before artificial checking monitoring video, improves probability and accuracy that expressway traffic accident finds, and accident can be reported by the very first time, saves huge cost of labor.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention；
Fig. 2 screens schematic diagram for the first time；
Wherein, A frame is highway video monitoring regional, and C is one section of highway in video surveillance region, B1, and B2 is two cars on highway.
Detailed description of the invention
A kind of based on monitor video automatic decision accident and the method reported to the police, as it is shown in figure 1, comprise the steps:
Step one, utilize the photographic head distributed network on highway that highway section carries out omnidistance seamless monitoring, and monitor video data are uploaded to DVR；
Step 2, utilize background system that the monitor video data above transmitted are carried out accident to screen for the first time, if the accident that do not screen out occurs, then directly these monitor video data are thrown on the monitoring screen of Speedway Control Broad；If the accident that screens out occurs, then send warning reminding staff；This step
The monitor video data sending warning reminding are carried out secondary examination by step 3, staff.
The first idiographic flow screened is as follows:
(1) image filtering system is run at background system, video information is cut into image one by one, then each two field picture is processed；
(2) as in figure 2 it is shown, when occurring vehicle B1, vehicle B2 and one section of highway C in highway video monitoring regional A, vehicle B1 and vehicle B2 symbolization are become tetragon by program, if one of following state occurs, then regard as the accident that screens out and occur；If following state does not occur, then directly these monitor video data are thrown on the monitoring screen of Speedway Control Broad；
One, two distances between adjacent quadrangular B1 and B2 of state are less than 10 pixels, and doubtful is that two cars knock into the back or bump against；
State two, tetragon B1 or B2 are not subjected to displacement at runway, for car, doubtful occur that accident or collision are stopped after knocking into the back；
State three, symbolization tetragon B1 or B2 beyond normal car body size, doubtful for there is auto-ignition；
(3) it is thrown on the monitoring screen of Speedway Control Broad regarding as the monitor video data that the accident that screens out occurs, and carries out warning reminding staff and carry out secondary examination by generation flickering effect on giant-screen or by the speaker sound that sounds the alarm.
