[0013] An intelligent camera follow-up monitoring alarm method comprises the following steps:

[0014] S1, the outer shell of the video surveillance alarm is set to a closed shell in the shape of an animal, a person or a cartoon character's head, and the camera module of the video surveillance alarm is arranged on the outer shell at the nose shape position, a processor CPU, a power supply, a wired defense zone, a GSM module, a radio frequency module, an antenna, an audible and visual alarm module, a wireless module and a display module are arranged in the video surveillance alarm, the display module is designed to be two liquid crystal display screens adapted to the eyes of the outer shell and arranged at the eye shape of the outer shell, the wired defense zone is connected to the CPU input end to send the detection information of the wired defense zone to the CPU, the CPU is respectively connected to the GSM module, the radio frequency module and the wireless module for communication, the GSM module and the radio frequency module send the alarm information to the user's smart phone through the antenna, the power supply is connected to the CPU power supply end, the camera module is connected and controlled by the CPU, and the CPU output end is respectively connected to the audible and visual alarm module and the display module;

[0015] S2, the camera module of the video surveillance alarm of step S1 is turned on for video surveillance in real time, and the image data of the surveillance area is collected and stored. The camera module sends the collected image data to the CPU for processing in real time. The CPU uses the difference frame method to determine whether a dynamic event occurs. First, the adjacent frame images are differentiated: the pixel values ​​at the same position of the adjacent frames are differentiated, and the pixel points corresponding to the moving part of the object in the image are found and performed on the image storing the difference result, and then binarization is performed: through threshold segmentation, the pixel points with obvious pixel value changes are extracted, and each row, The effective pixel points of the column are accumulated, that is, a two-dimensional array is used to record the pixel points and the corresponding index records; the effective pixel points of the two-dimensional array after binarization are sorted and filtered out: through the first step of statistics, we sort the accumulated numbers, and remove 20% of the data at the front and back ends after sorting according to the normal distribution law; average coordinates: after sorting and filtering, the remaining data index values ​​are accumulated and averaged to obtain the centroid coordinates of the effective pixel points. The calculation method of the centroid coordinate position is equivalent to finding the center of the rectangular area where 80% of the coordinates X distribution and 80% of the coordinates Y distribution are located. When the centroid coordinates change, it is determined that a dynamic event has occurred;

[0016] S3. After the dynamic event change is determined in step S2, the center of gravity coordinates of the effective pixel points are generated to follow the change, and the warning information generated by the comparison images before and after the center of gravity coordinates change is transmitted to the user alarm host for alarm. At the same time, on the two eye-shaped LCD screens of the video monitoring alarm, the information on whether the center of gravity coordinate position changes is followed and displayed in different forms on the two eye-shaped LCD screens.

The image data of the monitored area is first collected and stored on the CPU; the image data is post-processed, and the difference frame method combined with the center of gravity coordinate algorithm is used to determine whether a dynamic intrusion event has occurred; after the judgment, the warning information generated by the before and after comparison images of the center of gravity coordinate change is transmitted to the user for alarm, and the event information of the target area is collected and detected in real time by the monitoring camera and CPU image processing, so as to achieve the function of remote and real-time warning. The monitoring and warning process is convenient, intelligent and efficient, which effectively prevents the occurrence of emergencies such as home theft and fire; through further settings, that is, in the front The card slot and snap-fit ​​connection between the shell and the back shell further improve the stability of the shell connection. By combining the three-stage headphone plug and the three-stage headphone socket on the power supply circuit and connecting with the rotating seat 360°, the power output of the power supply circuit is transmitted to the upper surface of the rotating seat through the three-stage headphone plug and the three-stage headphone socket. The powered module is then arranged on the rotating seat, so that the camera and other powered components can be freely rotated 360° without affecting the power supply connection. The long wire connection is wirelessly set for power supply, and the information received through the image processing of the CPU is displayed on the LCD screen to follow the setting of different shapes of images for intuitive expression, such as the battery plus lightning mark combined with the image to indicate the charging status The red background mark with an underline in the middle and the battery combined with an image indicates that the battery of the power source is low and needs to be charged, etc. That is, the two eye-shaped LCD screens of the video surveillance alarm dynamically follow and display the corresponding states in different shapes of images on the two eye-shaped LCD screens according to the arming and disarming actions, AC power failure, and power information of the video surveillance alarm in real time. The video surveillance alarm's own various states are automatically followed and displayed on the two eye-shaped LCD screens. The changes in facial expressions are further followed to further enhance the concealment of the video surveillance alarm, making it easier for criminals to think that it is an irrelevant object such as a toy, further effectively improving the security function, and can be widely promoted and applied.

[0031] An intelligent camera follow-up monitoring alarm method comprises the following steps:

[0032] S1. The outer shell of the video surveillance alarm is set to be a closed shell in the shape of an animal, a person or a cartoon character's head, and the camera module of the video surveillance alarm is arranged on the outer shell at the nose shape position, and the display module of the video surveillance alarm is designed to be two eyeball-shaped liquid crystal display screens and arranged at the eye shape of the outer shell;

The camera module of the video surveillance alarm of step S1 is turned on for video surveillance in real time, and the image data of the surveillance area is collected and stored, the image data is processed, and the difference frame method is used to determine whether a dynamic event occurs. First, adjacent frames are differentiated: the pixel values ​​at the same position of adjacent frames are differentiated, and the pixel points corresponding to the moving part of the object in the image are found and performed on the image storing the difference result, and then binarization is performed: the pixel points with obvious pixel value changes are extracted through threshold segmentation, and the valid pixel points of each row and column on the binary image are accumulated with two-dimensional coordinates X and Y on the binary image, that is, a two-dimensional array is used to accumulate and record the pixel points and the corresponding index records; the valid pixel points of the two-dimensional array after binarization are sorted and filtered out: through the statistics of the first step, we sort the accumulated numbers, and remove 20% of the data at the front and back ends after sorting according to the normal distribution law; refer to Figure 6 , there is a two-dimensional array of the index and occurrence count of the 10 pixels on the X axis, the left side is the theoretical data, and the right side is the recorded data,

[0067] Average coordinates: After sorting and filtering, the remaining data index values ​​are accumulated and averaged to obtain the centroid coordinates of the effective pixel points. The calculation method of the centroid coordinate position is equivalent to finding the center of the rectangular area where 80% of the coordinates X distribution and 80% of the coordinates Y distribution are located; average them after the above filtering,

[0068] That is, the centroid of pixel distribution on the X-axis => (B[n][0]) / 6 = 4.8, so the actual effective pixel centroid coordinate 4.8 is calculated to be basically close to the centroid coordinate 5 of the theoretical motion focus, thus realizing the calculation of the effective pixel centroid coordinate;

[0069] S3, after the dynamic event change is determined in step S2, the centroid coordinates of the effective pixel points are generated to follow the change, and the warning information generated by the before and after comparison images of the centroid coordinates are transmitted to the user alarm host for alarm, reference Figure 7 , Figure 8 and Fig. 9 At the same time, on the two eye-shaped LCD screens of the video surveillance alarm, according to the information on whether the center of gravity coordinate position changes, the eyeball images of different forms are followed and displayed on the two eye-shaped LCD screens, that is, the CPU is set to draw the pupil and iris color on the LCD screen in combination with multiple highlight modes to output the status of the video surveillance alarm host in different eye images, and at the same time, the power detection circuit and the voltage detection circuit are set to detect the power and AC power supply status of the video surveillance alarm in real time. In the step S3, the two eye-shaped LCD screens of the video surveillance alarm also dynamically follow and display the corresponding status with different shapes of images on the two eye-shaped LCD screens according to the multiple states of the video surveillance alarm, such that the multiple different states of the video surveillance alarm itself are automatically followed and displayed on the two eye-shaped LCD screens. , such as arming and disarming, AC power failure, and low battery fault information animated images follow the display, and in the event of an alarm, the eyes will flash red and follow the display, similar to the animal behavior display. At the same time, the CPU can also edit and draw that when there is no human movement, the two eyes will blink once at a fixed time (such as 5 seconds). When the AC power is not supplied and the battery is low, the eyes will appear tired. When there is no alarm, if someone moves repeatedly for a period of time (such as 5 minutes), the eyes will appear in a contemptuous style. The image will follow the display, realizing the display of multiple animal eye simulation expressions to conceal the monitoring of the video surveillance alarm. The image displayed on the LCD screen follows the different states and operating states of the video surveillance alarm, and the different images are more vividly displayed according to the different states and operating states of the video surveillance alarm. The monitoring camera function of the device of the present invention is hidden by simulating animal eye expressions more effectively, achieving a better and more concealed security monitoring effect.

[0070] The present invention divides the shell body into three parts, namely, a front shell, a rear shell and a bottom shell, which are nested and detachably matched, so that the shell of the intelligent camera alarm can be quickly assembled by snapping and matching the arc convex edge with the groove edge. The overall assembly does not require screws or other locking methods. The structure is simple and reasonable, the production efficiency is improved, and the use and disassembly are convenient. The shape of the entire shell body is set to the head shape of an animal or a person, and a camera lens mounting port is provided on the front shell at the nose shape position. The lens of the camera module is arranged on the camera lens mounting port of the front shell. Two eyeball-shaped liquid crystal display screens of the display module are arranged on the front shell at the eye position to display the camera position of the camera module. This is significantly different from the shape of the existing intelligent camera alarm. Criminals are not easy to find, avoiding criminals from destroying in advance, and effectively improving security reliability. The image data of the monitored area is first collected and stored on the CPU; the image data is post-processed, and the difference frame method combined with the center of gravity coordinate algorithm is used to determine whether a dynamic intrusion event occurs; after the judgment, the warning information generated by the before and after comparison images of the center of gravity coordinate change is transmitted to the user for alarm, and the event information of the target area is collected and detected in real time by the monitoring camera and CPU image processing, so as to achieve the function of remote and real-time warning. The monitoring and warning process is convenient, intelligent and efficient, which effectively prevents the occurrence of emergencies such as home theft and fire; through further settings, that is, setting a card between the front shell and the back shell The groove and buckle matching connection further improves the stability of the shell connection. By combining the three-stage headphone plug and the three-stage headphone socket on the power supply circuit and connecting with the rotating seat 360°, the power output of the power supply circuit is transmitted to the upper surface of the rotating seat through the three-stage headphone plug and the three-stage headphone socket. Then, the powered module is arranged on the rotating seat, which can facilitate the camera and other powered components to rotate 360° freely without affecting the power supply connection. The long wire connection power supply is wirelessly set, and the information received through the image processing of the CPU is displayed on the LCD screen to follow the setting of different shapes of images for intuitive expression, such as the battery plus lightning mark combined with the image to indicate the charging state, the battery inside The red background logo with an underline combined with an image indicates that the battery of the power source is low and needs to be charged, etc., that is, the two eye-shaped LCD screens of the video surveillance alarm dynamically follow and display the corresponding states in real time according to the video surveillance alarm's arming and disarming actions, AC power failure, and power information on the two eye-shaped LCD screens with images of different shapes. The video surveillance alarm's own various states are automatically followed and displayed on the two eye-shaped LCD screens. The changes in facial expressions are further followed to further enhance the concealment of the video surveillance alarm, making it easier for criminals to think it is an irrelevant object such as a toy, further effectively improving the security function, and can be widely promoted and applied.
