Description
Technical field
The present invention relates to monitoring camera-shooting technical field, more particularly to a kind of automatically cleaning monitoring camera.
Background technology
Monitoring camera is a kind of relatively common monitoring device, and it can clearly record the thing occurred in monitoring range
Part, once occurring accident can be used as most direct strong evidence.Monitoring camera is mostly installed out of doors, throughout the year by environment
Influence is easy to make the impurity of the influence image-capturing resolutions such as the protective cover contamination dust on the outside of camera lens, has had a strong impact on monitoring effect
Really.All it is by manual cleaning, that is, to allow cleanup crew station in the cage of large-scale crane at present to clear up the dust on protective cover
Interior, crane slings cage and cleanup crew is sent to progress scouring cleaning near monitoring camera, again connects cage after the completion of cleaning
People puts down together.In order to ensure the safety of cleanup crew, it is necessary to assure cage can not be swung in the air, otherwise hidden in the presence of safety
Suffer from, and cleaning work requires also higher to weather condition.This manner of cleaning up is wasted time and energy, inefficiency, and uneasy
Entirely.
The content of the invention
(1) technical problem solved
In order to solve the above problems, the invention provides a kind of automatically cleaning monitoring camera, pass through what camera was shot
Image carries out self-inspection, judges whether to need to clean protective cover, to substitute traditional manual cleaning mode.
(2) technical scheme
A kind of automatically cleaning monitoring camera, including protective cover and camera body, the camera body include camera
Sensor, microprocessor and memory, the camera body also include image selftest module, motor and water injector,
Described image selftest module is interconnected with the camera sensing device, the described image selftest module output connection microprocessor
Device, the microprocessor is connected with the motor, and the motor controls the water injector to enter the protective cover
Row cleaning.
Further, described image selftest module receives the image that the camera sensing device is shot, and every image is given birth to
Into " fingerprint " character string and it is compared, its step is as follows：
A1, pre-stored initial pictures, initial described " fingerprint " character string of generation；
B1, acquisition contrast images, " fingerprint " character string described in generation contrast；
C1, initial " fingerprint " character string of comparison and " fingerprint " character string described in contrast, obtain variance data digit.
Further, described " fingerprint " character string is cryptographic Hash, and implementation step is as follows：
A1, minification：By the size of image down to 8*8,64 pixels altogether；
B1, simplified color：By the image after diminution, switch to 64 grades of gray scales；
C1, calculating average value：Calculate the average gray of all 64 pixels；
D1, compared pixels gray scale：By the gray scale of each pixel, it is compared with average value, more than or equal to average value
1 is designated as, 0 is designated as less than average value；
E1, calculating cryptographic Hash：By the comparative result of previous step, combine, constitute the integer of one 64.
Further, the water injector is located on the outside of the protective cover.
(3) beneficial effect
The invention provides a kind of automatically cleaning monitoring camera, self-inspection is carried out by the image shot to camera, judged
Whether need to clean protective cover, efficiently solve due to the inconvenient problem of maintenance that monitoring camera installation site is caused, protect
The cleaning outside monitoring camera is demonstrate,proved, so as to improve monitoring effect, whole process also saves manual cleaning without manual intervention
Cost.
Brief description of the drawings
Fig. 1 is a kind of fundamental diagram of automatically cleaning monitoring camera involved in the present invention.
Fig. 2 is a kind of image self-inspection flow chart of automatically cleaning monitoring camera involved in the present invention.
Fig. 3 is a kind of " fingerprint " character string implementation process figure of automatically cleaning monitoring camera involved in the present invention.
Embodiment
Embodiment involved in the present invention is described in further details below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of automatically cleaning monitoring camera, including protective cover and camera body, camera body includes
Camera sensing device, microprocessor and memory, camera body also include image selftest module, motor and water spray dress
Put, image selftest module and camera sensing device are interconnected, image selftest module output connecting microprocessor, microprocessor with
Motor is connected, and motor control water injector is cleaned to protective cover.
Water injector is located on the outside of protective cover.
Image selftest module receives the image that camera sensing device is shot, and " fingerprint " character string is generated to every image
And be compared, its step is as shown in Figure 2：
A1, pre-stored initial pictures, initial " fingerprint " character string of generation；
B1, acquisition contrast images, generation contrast " fingerprint " character string；
C1, initial " fingerprint " character string of comparison and contrast " fingerprint " character string, obtain variance data digit.
" fingerprint " character string is cryptographic Hash, and implementation step is as shown in Figure 3：
A1, minification：By the size of image down to 8*8,64 pixels altogether；
The effect of this step is the details for removing image, only retains the essential information such as structure or light and shade, abandons different sizes
Or the image difference that ratio etc. is brought.
B1, simplified color：By the image after diminution, switch to 64 grades of gray scales；
I.e. all pixels point only has 64 kinds of colors altogether.
C1, calculating average value：Calculate the average gray of all 64 pixels；
D1, compared pixels gray scale：By the gray scale of each pixel, it is compared with average value, more than or equal to average value
1 is designated as, 0 is designated as less than average value；
E1, calculating cryptographic Hash：By the comparative result of previous step, combine, constitute the integer of one 64.
Here it is " fingerprint " of this image, the order of combination is unimportant, as long as ensureing all images all using same
Order is just.
After obtaining fingerprint, it is possible to contrast different images, look at how many position is different in 64.In theory
On, this equates " Hamming distance " (Hamming distance, in information theory, the Hamming distance between two isometric character strings
From the number for the kinds of characters for being two character string correspondence positions).If the data bits differed is no more than 5, just explanation two
Open image；If greater than 10, it is two different images just to illustrate this.
When impurity is more on the protective cover of monitoring camera, contrast " fingerprint " character string that image selftest module is obtained with
Initially " fingerprint " character string compares, the data bits differed must be more than 10, image selftest module by comparative result send to
Microprocessor, microprocessor sends control command and cleaned to motor driving water injector to protective cover.
The invention provides a kind of automatically cleaning monitoring camera, self-inspection is carried out by the image shot to camera, judged
Whether need to clean protective cover, efficiently solve due to the inconvenient problem of maintenance that monitoring camera installation site is caused, protect
The cleaning outside monitoring camera is demonstrate,proved, so as to improve monitoring effect, whole process also saves manual cleaning without manual intervention
Cost.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the structure of the present invention
Think and scope is defined.On the premise of design concept of the present invention is not departed from, technology of this area ordinary person to the present invention
The all variations and modifications that scheme is made, all should drop into protection scope of the present invention, claimed technology contents of the invention,
All record in detail in the claims.
