Fig. 2 is the structure frame-type schematic diagram of one embodiment of the present invention.
Embodiment
The present invention will be further described with reference to the accompanying drawings.
With reference to Fig. 1, a kind of Smart Home method for supervising based on motion detection, comprises the following steps:
(1) CCTV camera monitoring of a recorded programme region monitor video and by transmission of video to processor;
(2) while recording, processor adopts Three image difference to detect the moving object that guarded region occurs and background objects to the monitor video recorded;
(3) processor judges the moving object sentencing guarded region, judges whether it reaches the extraction threshold value pre-set;
(4) if moving object does not reach extraction threshold value in step (3), then processor repeats step (2) to the video of follow-up recording, if moving object reaches extraction threshold value in step (3), then processor extracts moving target automatically;
(5) after step (4) extracts moving target, target information to guard monitor Shi Gei community, community guard and alarm, is transferred on the terminal equipment of householder by processor control watch-dog by picture transmission simultaneously.
In above-mentioned steps (4), processor adopts the mode of mixed Gauss model background to extract moving target.
The terminal equipment of householder is computer in above-mentioned steps (5), target information in the mode of monitored picture by network and/or Bluetooth transmission to householder.
In above-mentioned steps (5), the terminal equipment of householder is mobile phone, and target information passes through 3G/2G Internet Transmission to householder in the mode of note.
Composition graphs 2, adopt an Intelligent home monitoring system for method described in claim 1, its technical scheme is, native system comprises CCTV camera, processor, Surveillance center and personal terminal, wherein, processor is connected with CCTV camera, Surveillance center and personal terminal respectively.
Above-mentioned processor is also connected with holder and communicator.Holder stores video information, checks and transfers after convenient, communicator in the mode of wire/wireless by video information transmission to remote terminal, even make, Surveillance center is distant also can receive information.
Described communicator is 2G/3G communicator.Adopt 2G/3G as information transmission mode, technology maturation, can carry out transmitting with 2G short message mode also to adopt 3G information to transmit, select wide, be easy to connecting wireless network.
In the present embodiment, motion detection and GPRS are combined, adopt new process core, utilize the portability of embedded system, in endorse cutting, feature that application is strong, camera collection video flowing is started by cgi script, start image that the dominant frequency DSP higher than ARM core check collection to take exercises detections, whether someone invades in detection, and passes to cell monitoring center by ethernet controller by network simultaneously.If someone invades, on the one hand the picture of Surveillance center is switched to this user family, be used for community guard and alarm, start bluetooth on the other hand, by bluetooth and Web server, the image collected is passed to PC in family, start GPRS SMS alarm function simultaneously, send short messages and notify user, user by PC in browser access family, thus can reach the effect of monitoring.
In the course of the work, detection moving target is the prerequisite to the subsequent treatment such as target classification and identification to the present embodiment, and its performance directly affects the validity of supervisory control system, is the key components of intelligent video monitoring system.The present invention adopts a kind of moving object detection algorithmic method mixed Gauss model and Three image difference combined.First the method goes out region of variation by Three image difference fast detecting, and utilize Three image difference high and automatically can remove the advantage that background appears district to the detection sensitivity of moving target, solve large and slow moving object detection weak effect and the problem of " shadow " occurring foreground object in testing result, then add up by the testing result of statistical method to Three image difference, judge whether present frame reaches extraction threshold value, the need of the Objective extraction it being carried out to mixed Gauss model background method, greatly reduce the amount of calculation of algorithm, be conducive to the real-time process of algorithm.Three image difference utilizes adjacent 3 two field pictures between two after difference, then does binary conversion treatment and obtain image d1, d2, finally image d1, d2 done mutually and computing, thus draw the region of variation in image.
In Three image difference, the selection of threshold value is extremely important, determines the sensitivity of detection.The sensitivity of certainly different application requirements is different.Because in difference result image, the change of foreground area grey scale pixel value meets non-gaussian distribution greatly, and grey scale pixel value change is little but affected by noisely meet Gaussian Profile in background area, must criterion be met for Gaussian data, therefore in the present invention, adopt criterion setting threshold thresholding.
In Smart Home monitor procedure, the scene major part in monitoring household is in static constant, and the region of variation therefore utilizing three frame methods to detect is caused by scene Self-variation mostly.Continue to carry out the object matching of mixed Gauss model to image in the non-existent situation of this moving target and to extract be unnecessary, only can increase the computational burden of system, affect real-time.When having moving object invasion, the number of pixels of moving in video image is more.Therefore, utilize this characteristic to add up the number of pixels of moving in bianry image, when only having motion pixel to be greater than threshold value, just think and have moving object to exist, just it is carried out to next step process.
The above; for better case study on implementation of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure change, all still belong in the protection range of technical solution of the present invention.
