Abstract
The invention provides an image monitoring and alarm method comprising the following steps that a camera is connected with a monitoring host, a standing object is monitored, the camera captures the initial image of the standing object to act as an original reference image to be saved when monitoring starts, and the monitoring host loads the original reference image; the camera captures a real-time image of the standing object after starting of monitoring and the real-time image is compared with the original reference image after image gray processing, and the monitoring host emits an alarm prompt if the comparison result meets the definition; and the real-time image is saved if the comparison result of the real-time image and the original reference image does not meet the definition and monitoring is continued. The method of computer vision is adopted, and image gray processing is performed on the image sequences photographed and recorded by the camera and comparison is performed almost without artificial interference so that movement of the image can be recognized, and timely alarming can be performed through computer software.
Description
Technical field
The invention provides a kind of picture control alarm method, for the object stood being realized monitoring automatically, reporting to the police, belong to
In electronic security field.
Background technology
Along with the quickening of safe city pace of construction, safety-protection system construction be extend to work as by the key departments at country's initial stage
The every field such as the public place of the present, heavy construction, finance, traffic, community.The video monitoring system of application is sudden and violent now
The problem exposed also gets more and more, and most important of which is exactly a little that existing monitoring system cannot identify different automatically
Object, it is impossible to the automatically abnormal conditions in monitored picture, and can by the fastest and optimal in the way of automatically send alarm and carry
For useful information.
The problem existed for existing monitoring system, the concept of Intelligent Recognition is proposed out.Intelligent recognition monitoring system one
Aspect is to be analyzed mass data by area of computer aided, by compression storage, recognition of face, intelligent retrieval and net
The technology such as network transmission have been dissolved in video monitoring product, make the quality of video monitoring to be greatly improved；The opposing party
Face Intelligent Recognition secondary computer can be arranged automatically by user, unconcerned for user information is directly filtered out, and is only prison
The key message that control person is provided with, on the basis of this, intelligent recognition monitoring system can more efficiently assist safety
Personnel process crisis, and reduce wrong report to greatest extent and fail to report phenomenon.
Summary of the invention
The invention provides a kind of picture control alarm method, image, by controlling video camera, is carried out periodically by the method
Collection, and by Digital Image Processing, picture is carried out the sequence of operations such as conversion process, with real time imaging with former
Beginning reference picture contrasts, if finding, the real time imaging gathered is different with original reference image, is issued by reporting to the police,
To reach effectively to prevent from standing the purpose that object is stolen.
Realizing the technical scheme that above-mentioned purpose of the present invention used is:
A kind of picture control alarm method, comprises the following steps: (1), by high speed infrared monopod video camera and monitoring host computer
Connecting, be monitored standing object, when monitoring starts, high speed infrared monopod video camera captures the initial graph standing object
Picture is as original reference image and preserves, and monitoring host computer is loaded into original reference image, processes original reference image,
Improve image quality, make the display effect of image become apparent from；
(2), after monitoring starts, high speed infrared monopod video camera captures real time imaging to standing object, and carries out image ash
Degree contrasts with original reference image, if comparing result meets following condition: real time imaging and original reference image after processing
Pixel is subtracted each other poor absolute value and is more than 20, then monitoring host computer sends alarm；
(3) in monitoring host computer, it is provided with interval holding time t, if the contrast knot of real time imaging and original reference image
Fruit is unsatisfactory for following condition: real time imaging and original reference image pixel are subtracted each other poor absolute value and be more than 20, sentence the most further
The time interval of the real time imaging of twice crawl before and after Duan, if time interval is more than or equal to interval holding time t, then supervises
Control main frame to after the real time imaging that once captures preserve, and continue monitoring；If time interval is less than the interval holding time
T, then the real time imaging once captured after deleting does not preserves, and then proceedes to monitoring.
Compared with prior art, the invention have the advantages that the method that the present invention uses computer vision, hardly
In the case of wanting human intervention, by the image sequence of video camera recording being carried out the gray proces of image and contrasting,
Thus identify image either with or without being moved, and warning can be provided in time by computer software.
Accompanying drawing explanation
The schematic flow sheet of the picture control alarm method that Fig. 1 provides for the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention done detailed specific description, but protection scope of the present invention is not limited to
In following example.
Using the historical relic in museum as monitored object in the present embodiment, the technical scheme of the application is further retouched
State.Owing to the historical relic in museum is the most all placed on changeless position, unauthorized position mobile visible is illegal
Larceny.
Method provided in the present embodiment as it is shown in figure 1, by infrared integrated camera and high speed infrared monopod video camera with
Monitoring host computer connects, and is monitored Cultural relics in museum, opens by C++ and VFW (Video on monitoring host computer
Window) the picture control warning system software developed, clicks on and starts monitoring, and video camera captures original reference image also
Preserving, monitoring host computer is loaded into original reference image, original reference image is carried out gray proces, improves image quality, make image
Display effect become apparent from.
After monitoring starts, high speed infrared monopod video camera captures real time imaging to standing object, and carries out gradation of image process
Contrasting with original reference image afterwards, if comparing result meets definition, (real time imaging and original reference image pixel subtract each other difference
Absolute value more than 20) then the computer software in monitoring host computer send alarm.
If real time imaging is unsatisfactory for defined above with the comparing result of original reference image, then judge whether to reach setting
Interval holding time t, is provided with interval holding time t in monitoring host computer in advance, and this interval holding time, t can will grab
The real time imaging taken is saved in appointment position, if reaching to be spaced the holding time, then preserving image, continuing monitoring；If
It is not reaching to be spaced the holding time, then deletes image, continue monitoring.
Claims (1)
1. a picture control alarm method, it is characterised in that comprise the following steps: (1), by high speed infrared The Cloud Terrace image
Machine is connected with monitoring host computer, is monitored standing object, and when monitoring starts, high speed infrared monopod video camera captures and stands
The initial pictures of object is as original reference image and preserves, and monitoring host computer is loaded into original reference image, to original reference figure
As processing, improve image quality, make the display effect of image become apparent from；
(2), after monitoring starts, high speed infrared monopod video camera captures real time imaging to standing object, and carries out image ash
Degree contrasts with original reference image, if comparing result meets following condition: real time imaging and original reference image after processing
