Abstract
The invention provides a video monitoring method and a video monitoring device, which belong to the field of network communication. The method comprises the following steps that: a sensor node acquires an initial image by using a low-pixel image capturing device and uploads the initial image to a server for saving; the sensor node continues acquiring a new image by using the low-pixel image capturing device, grays the new image and the initial image, and then compares the pixel variance between the two images; if the pixel variance between the two images is greater than a preset threshold, the sensor node uploads the new image to the server; the server compares the new image with the initial image; and if the server judges that an object moves according to a comparison result, the server triggers the high-pixel image capturing device of the sensor node to acquire image and stores the image acquired by the high-pixel image capturing device. The method and the device have the advantages of small data transmission amount and little loss.

Embodiment
The specific embodiment of the invention provides a kind of method of video monitoring, and this method comprises as shown in Figure 1:
S11, sensor node adopt low pixel camera equipment to gather initialisation image, and this initialisation image is uploaded to the server preservation;
Linking of above-mentioned picture pick-up device and sensor node can the selection standard interface, for example: SPI, I2C, UART, Intel Quick Capture etc.; Certainly high-pixel camera equipment also can adopt above-mentioned standard interface, and the image of above-mentioned collection preferentially selects to adopt the JPEG coding.
Optionally, the sensor node adopts low pixel camera equipment to gather initialisation image and is specifically as follows: low pixel camera equipment is gathered many images, from many images of gathering, select one as initialisation image by the keeper, can certainly adopt other mode to determine initialisation image, first image that for example will hang down the collection of pixel camera equipment is as initialisation image.
S12, sensor node continue to adopt the low new image of pixel camera equipment collection, and with compared pixels variance behind new image and the initial pictures gray processing, as the pixel variance of two images greater than setting threshold, then with new image uploading to server;
S13, server compare new image and initial pictures, when judging according to comparative result that there are objects moving, trigger the high-pixel camera equipment images acquired of sensor node, and store the image that this high-pixel camera equipment is gathered.
The above-mentioned method that judges whether that relatively there are objects moving can adopt advanced algorithm, and more whether there are objects moving, and advanced algorithm is specifically as follows: adopt the image abnormity characteristic detection method, realize that server compares new images and initialized image once more.
For example, when a certain scene of camera head monitor, there is a people to swarm into according to colorimetric detection, because people's skin tone value and conventional environment have clearly different,
Then by the following method,
Method one at the RGB scope of skin color, is compared to the RGB information of image block, when surpassing empirical value, thinks that then the finder swarms into.
Method two, the rgb signal of two width of cloth images is transformed into YUV signal, extracts colourity and color difference components UV information and compares, and when surpassing empirical value, then detects the people and swarms into.
This patent adopts this image abnormity characteristic detection method, and above-mentioned two kinds of methods are instantiation, and the image abnormity feature detection algorithm of patent is not limited to this two kinds of methods, and the needs basis type of image is in actual applications regulated threshold value or replacing method.
Optionally, said method can also comprise:
S14, server apparatus send alarm to the keeper.
The method of above-mentioned realization S14 can for: server sends the mail of alarm or the information of alarm by the internet to the keeper; Can certainly be other alarm mode, send the multimedia message that has above-mentioned new images as the mobile phone to the keeper, can also have other mode to send alarm certainly, the present invention does not limit to the practical ways of this alarm.
Optionally, the communication mode of the sensor node and server can adopt the mode of radio communication, and concrete realization can be referring to the associated description among the IEEE802.15.4.After adopting communication, the locomotivity of sensor node increases, and has made things convenient for the layout of sensor node, and has not also worried occurring cable fault.
Optionally, the scene setting that the sensor node can be monitored as required is a plurality of, the keeper also can carry out corresponding setting to sensor node voluntarily, closure sensor node for example, the threshold value of pixel variance is set, directly open or close high element sensor node, the keeper realizes that the mode of above-mentioned setting can adopt remote mode, for example come Control Server to finish aforesaid operations by the internet, can certainly adopt other mode, for example directly come Control Server to finish aforesaid operations by the mode of SMS, certainly the keeper also can revise above-mentioned setting by the mode that this locality is provided with, and the present invention does not limit to the concrete mode of revising above-mentioned setting.
Only just starting high-pixel camera equipment under the situation of finding movement of objects and carrying out work of method provided by the invention reduced the video data volume, and volume of transmitted data is little, and power loss is also less.By facts have proved, the image of the monitoring scene under most of situation all is identical, so adopt above-mentioned method for supervising, can guarantee the quality monitored can reduce the video data volume again, reduces data quantity transmitted, reduces power loss.
The invention provides a kind of device of video monitoring, this device comprises as shown in Figure 2: sensor node 21 and server 22;
Optionally, server 22 also is used for sending alarm to the keeper.
Optionally, sensor node 21 adopts the mode of radio communication to be connected with server 22.
Optionally, the sensor node 21 is a plurality of (Fig. 2 does not draw).
Optionally, above-mentioned picture pick-up device is selected SPI for use with being connected of sensor node, I2C, UART or Intel Quick Capture interface.
The device that present embodiment provides only just starts high-pixel camera equipment and carries out work under the situation of finding movement of objects, reduced the video data volume, and volume of transmitted data is little, and power loss is also less.By facts have proved, the image of the monitoring scene under most of situation all is identical, so adopt above-mentioned method for supervising, can guarantee the quality monitored can reduce the video data volume again, reduces data quantity transmitted, reduces power loss.
