Description
Technical field
The present invention relates to the video detection technology field in lift car, more particularly to elevator to lose the detection technique of junk.
Background technology
It is the thing that many people will undergo daily to take elevator, and thing can be lost in elevator by some people due to carelessness
In, since elevator is public instrument, running at any time, losing junk and be possible to be picked up away by other people, unnecessary wealth is caused for the owner of lost property
Production loss.
Some schemes for the object detection being also related in the prior art in elevator, such as Chinese patent
CN2006800281691, discloses a kind of article detection device of elevator, which has：Image acquisition unit,
Its background image for obtaining the present image photographed by the ministry of photography and being photographed when detection object is not present in monitor area；
Background profile line information extraction unit, it extracts the contour line information of the background image；And object detection unit, its basis
Could be extracted based on the contour line information of the background image from the present image except background image contour line it
Outer contour line, to detect detection object is whether there is in monitor area, the object detection unit is in the predetermined of the present image
At the pixel of coordinate during Extracting contour, according to the contour line information of the background image come judge the coordinate of the pixel whether be
The coordinate of contour line present position in the background image, be determined as be contour line present position in the background image seat
Timestamp, reduces the detection sensitivity of contour line, then the Extracting contour at the pixel.The shortcomings that program, is：The program
Body outline that may be present in background Differential Detection carriage is relied primarily on, further utilizes contour line information analysis carriage
Inside whether it is implicitly present in object.The object that the shortcomings that program is to detect cannot be distinguished by human body or other objects, because
Whether this can not differentiate has something lost junk to be present in elevator.
The content of the invention
In order to overcome the defects of background technology, improve elevator and lose the detection efficiency of junk and efficiency of reporting lost property to the authorities, present invention head
The automatic checkout system that a kind of elevator loses junk is first provided.
For this reason, the technical solution adopted in the present invention is：A kind of elevator loses the automatic checkout system of junk, including video is adopted
Collect unit, human body signal collecting unit, button signal collecting unit, something lost junk analytic unit and alarm logic analysis unit, depending on
Frequency collecting unit is installed on elevator car roof and is used to gather the image information in elevator door position and lift car, human body signal
Collecting unit be installed in lift car be used to gathering in lift car whether the signal of someone, the installation of button signal collecting unit
On push button panel in lift car, for gathering the button trigger signal of push button panel, video acquisition unit and human body letter
Number collecting unit, which is connected to, to be lost junk analytic unit and sends the information collected to junk analytic unit is lost, and loses junk point
Analysis unit has analysed whether something lost junk according to above- mentioned information, and analysis result is sent to alarm logic analysis unit, button letter
Number collecting unit sends button trigger signal to alarm logic analysis unit, and alarm logic analysis unit is according to losing junk analysis
Analysis result and button trigger signal the generation alarm signal of unit are simultaneously sent to administration departments.
Further, video acquisition unit includes the one or more in monitor camera, industrial camera.
Further, human body signal collecting unit includes the one or more in pir sensor, microblogging sensor.
Further, button signal collecting unit includes the control panel with push-button in lift car, button touch screen, Huo Zheyu
The trigger signal harvester that control panel with push-button and button touch screen are connected, for gathering button triggering information, so as to obtain
Take the corresponding floor information of button.
Further, losing junk analytic unit is included in general purpose processing device CPU, ARM, DSP, GPU, FPGA, ASIC
It is one or more.
Further, alerting logic analysis unit is included in general purpose processing device CPU, ARM, DSP, GPU, FPGA, ASIC
One or more.
The invention solves another technical problem be to provide the automatic testing method that a kind of elevator loses junk, this method
Using above-mentioned automatic checkout system, and comprise the following steps：
（1）Human body signal collecting unit collection lift car in whether the signal of someone, and send to lose junk analytic unit；
（2）Full figure information in the door state information and lift car of video acquisition unit collection lift car, and send extremely
Lose junk analytic unit；
（3）Button signal collecting unit gathers button triggering information and the corresponding building in lift car on push button panel in real time
Layer, and send this information to alarm logic analysis unit；
（4）Junk analytic unit is lost according to step（1）And step（2）Middle gathered information judges whether to lose junk；
（5）Lose junk analytic unit and will determine that out that the information with the presence or absence of something lost junk is sent to alarm logic analysis unit；

There is the article more than background image in railway carriage or compartment, losing the output of junk analytic unit has the information for losing junk, if foreground point accounting is little
In threshold value TH2, then illustrate to lose the information that junk analytic unit exports nothing left junk without the article for being more than background image in carriage；
（4.7）Carriage background is updated using the method for mixed Gaussian background modeling.
Further, alerting the specific step that performs of logic analysis unit includes：
（6.1）Alert logic analysis unit and receive the signal for losing junk analytic unit, if nothing left junk, is exited, if
Junk is lost, then is entered in next step；
（6.2）Alarm logic analysis unit record, which receives, loses the floor that the elevator button in junk signal previous minute activated
Information, and will there is something lost junk and the above-mentioned floor information activated to send to administration departments；
（6.3）Alarm logic analysis unit can also extract the video letter that video acquisition unit is shot within above-mentioned previous minute
Breath, with step（6.2）Information together send to administration departments.
The beneficial effects of the invention are as follows：The present invention gathers elevator by the video acquisition unit installed in elevator car roof
Interior panoramic picture, whether the method being combined by image procossing and multiple sensor signals is analyzed in carriage has object to deposit
In combination with button logic and elevator networking technology, property is being notified in time, and property is sent to related owner loses junk letter
Breath, method of the invention improves the accuracy rate for losing junk detection, and the state of someone in lift car is excluded detecting
Beyond scope, unnecessary detection is avoided, saves resource, improve detection efficiency, the present invention is also by elevator button
Corresponding floor detection notice to property so that timely and accurately reaction lose junk may corresponding owner of lost property's information, for the owner of lost property
While giving lost article for change and improve probability, the also work for property is provided convenience and reliability.
