Description
Technical field
The present invention relates to security field more particularly to a kind of security systems based on image procossing.
Background technique
With the rapid development of economic level and science and technology, the security precautions of people are also higher and higher.In order to right
Pay various economic criminal offenses, protect the life of the people and the safety of property, using high-tech means prevention and
It prevents crime and has become the common recognition in security personnel field.
However, the limitation of habitually in the past traditional video monitoring and alarm network system by state-of-art at that time, TV
Monitoring system can only be monitored although network alarm network can be carried out longer-distance warning message transmission at the scene mostly,
The disadvantages of but there is easy wrong report, the warning message of transmission is simple, is unable to transmitting video image, can not timely and accurately understand
The situation of the site of the accident, alert event confirmation is difficult, and system effectiveness is lower, security personnel can be made to lose vigilance over time, produced
The thought of raw paralysis absent-mindedness.
Remote image transmission traditional in the past, is generally transmitted using special optical cable or microwave, is easy by landform
With the limitation of route, and cost is high, and general user is difficult to receive, and therefore, is not easy to promote and apply.
In addition, legacy system is after an event occurs, just to send someone to take video-tape to scene, the warp of event generation is thumbed
It crosses, but when being usually that incident is more, can not know scene during incident the last period, and the image of video-tape is generally not clear enough
It is clear.
Summary of the invention
To solve the above-mentioned problems, it cracks alarm platform, can be closed in car owner the present invention provides a kind of automotive window
Engine and after locking to four car doors, the position of active detecting vehicle window and the gap of vehicle window, particular, it is important that window
During body target identification, target area and nontarget area are obtained by the way of to image analysis edge line to be identified,
After the subsequent recognition failures of target area, feed back to adjust acquisition of the images to be recognized to target area, and recycle and identified
Journey is until identifying successfully.
More specifically, the present invention at least has the important inventive point in following a few places:
(1) target area and nontarget area are obtained by the way of to image analysis edge line to be identified, it is more crucial
, after the subsequent recognition failures of target area, feed back to adjust acquisition of the images to be recognized to target area, and recycle knowledge
For other process until identifying successfully, the target identification mode of this circulation feedback reduces the operational data amount and meter of identification
Calculate complexity；
(2) different features is distributed based on both form region and non-form region lightness to identify forms target,
Improve the accuracy of identification of forms target；
(3) the texture variations amplitude of pre-acquisition image is analyzed, by the built-in skin texture detection unit of camera to be based on obtaining
The texture variations amplitude adjustment camera obtained finally shoots the real-time resolution of image, thus guaranteeing subsequent image treatment effect
While, reduce unnecessary image operation and energy loss；
(4) on the basis of accurate forms detect, the situation of cracking of vehicle window is detected, in the unmanned situation of automobile
Under, symmetry slot situation carries out and alarm.
According to an aspect of the present invention, it provides a kind of automotive window to crack alarm platform, the platform includes:
The front end of automobile is arranged in car door detection device, connect respectively with four Car's door controlling devices of automobile, the car door
Detection device is used to receive the current state of each car door, and the car door detection device is also used to determining that four car doors are all pass
When closed state, lock signal on car door is issued, otherwise, the non-lock signal of car door is issued and is simultaneously emitted by unlocked door position；
The front end of automobile is arranged in engine condition analytical equipment, connect with the engine of automobile, the engine condition
Analytical equipment is for detecting whether engine is in flameout state, accordingly to issue misfire detection signal or operation detection signal；
Starting device is imaged, is connect respectively with the engine condition analytical equipment and the car door detection device, it is described
It images starting device to be used in lock signal on receiving the misfire detection signal and the car door, controls interior camera
Structure enters screening-mode, otherwise, controls interior photographic unit and exits screening-mode；
Interior photographic unit is arranged in automotive interior, for automobile indoor setting image to be shot and exported to automobile indoor setting,
The car photographic unit is built-in with pre-acquired unit, skin texture detection unit and resolution adjustment unit；
Window frame detection device, is arranged in the instrument board of automobile, connect with the interior photographic unit, described for receiving
Automobile indoor setting image carries out edge detection to the content in the automobile indoor setting image, to obtain in the automobile indoor setting image
Multiple edge lines, the multiple edge line includes multiple horizontal edge lines, multiple vertical edge lines and multiple other types sides
Edge line takes the horizontal edge line of the horizontal edge line of the top and bottom in the multiple horizontal edge line, takes multiple vertical
The vertical edge line of the vertical edge line of the leftmost side and the rightmost side in edge line obtains rectangle subgraph based on above-mentioned four edges edge line
