Detailed Description
As shown in fig. 1-7, see fig. 1, 2, 3, and 7, includes
The system comprises at least three image acquisition devices, a first image acquisition device and a second image acquisition device, wherein the at least three image acquisition devices are respectively used for acquiring first video data of at least three image acquisition areas;
the display screen is used for intensively displaying at least three first video data acquired by at least three image acquisition devices;
the variable acquisition module is used for acquiring the video image frame of each first video data within a second time threshold and outputting a first variable according to the video image frames within the adjacent second time threshold; a first database for storing a first variable threshold;
a first processor for comparing a magnitude of a first variable to a first variable threshold,
if the first variable of all the first video data in the adjacent second time threshold is smaller than the first variable threshold, all the first video data display modes are converted into an initial state and output as a monitoring picture to a display screen;
wherein a display area of each first video data of the initial state is the same;
if the first variable of the first video data in at least one adjacent second time threshold is not smaller than the first variable threshold, converting the first video data corresponding to the first variable not smaller than the first variable threshold into primary video data, converting the mode that the primary video data is amplified and displayed and other first video data are not displayed into a first state, and outputting the first state as a monitoring picture to the display screen.
According to the invention, the first processor is used for comparing the first variable in each first video data with the first variable threshold value, and improving the proportion of the video picture of the first video data with larger variation amplitude in the monitoring picture, so that a monitoring person is reminded that the variation of the first video data is larger, and the problem possibly occurs in the image acquisition area corresponding to the first video data, thereby helping the monitoring person to increase the attention to the area or make a countermeasure in time, not only greatly reducing the labor intensity of the monitoring person, automatically recommending the monitoring image with larger variation, and more effectively improving the monitoring efficiency and accuracy.
Wherein the first variable may be: y is the sum of R, G, B values for each pixel of x video image frames in the first video data within a first second time threshold1Y, and the R, G, B value for each pixel of the x video image frames in the first video data within a second time threshold2In comparison, the first variable may be Y2-Y1Wherein the first second time threshold is adjacent to the second time threshold.
The invention sets Y in the first video data1、Y2To convert the image picture variation into the form of comparable data, and addThe processing speed of the processor is increased, the operation time and hardware requirements of the processor are reduced, and the purposes of reducing cost investment and improving reliability are achieved.
For example, the second time threshold is 3 seconds, and the first video data outputs video at 60 frames per second. Then, the first video data displays video at 1080 p. The R, G, B value of each pixel can be respectively an integer between 0 and 255, wherein the R value of the pixel of the first and second time thresholds is 235, the G value is 24, and the B value is 18. The R value of the pixel of the second time threshold is 205, the G value is 50, and the B value is 36. Y of a first and a second time threshold1Can be as follows: 1920*1080*60*(235+24+18). Y of a second time threshold2Can be as follows: 1920*1080*60*(205+50+36).
It should be noted that the present invention defines R, G, B values of each pixel as being the same for the sake of example, in the actual calculation, R, G, B values of each pixel of each frame may be different, which should be calculated separately, and the results of the separate calculations are added together to obtain Y1、Y2。
The first variable may be an image transformation percentage, such as a change in the number of pixel blocks, within a second time threshold by using existing video comparison software or image comparison software, so as to determine whether the first variable is greater than a first variable threshold, which is not described herein in the prior art.
Wherein, the centralized display can be that a plurality of video image contents are displayed on the same screen in the form of N grids. The above-mentioned N palace check can be: the video image content is displayed in 1/N area of the screen with equal area, and of course, the video image data with N equal areas or different areas may be displayed simultaneously on the same horizontal line.
The invention is suitable for the problem of arrangement caused by a large number of or a small number of monitoring pictures by setting a centralized display mode, thereby reducing the sight movement of monitoring personnel to the maximum extent and lightening the labor intensity of the monitoring personnel.
Wherein the first variable threshold may be: 102～1012Preferably 105。
According to the invention, the first variable threshold value is set, so that the numerical value of the first variable can be timely triggered when the fluctuation is large, and monitoring personnel can be timely reminded of paying attention to the picture when the picture is changed.
As shown in fig. 2, wherein the display area of the first video data of the primary video data is enlarged and displayed at least 3 times as large as the display area of the first video data in the initial state.
According to the method and the device, the amplification display of the primary video data is at least 3 times, so that monitoring personnel can be helped to distinguish the primary video data more intuitively and clearly and follow-up continuous attention is facilitated.
As shown in fig. 3, if there are a plurality of the primary video data, the plurality of the primary video data are uniformly arranged, and after the plurality of the primary video data are amplified, the lengths and widths of the plurality of the primary video data in the monitoring picture are reduced by the same number of the primary video data.
According to the invention, after the plurality of the primary video data are amplified, the lengths and the widths of the plurality of the primary video data in the monitoring picture are reduced by the same multiple of the number of the primary video data, so that all the primary video data are reasonably arranged and monitored in the monitoring picture, and further, all the primary video data are ensured to be monitored by monitoring personnel.
For example: when no suspicious person goes in and out, the display screen displays images of 20 image acquisition areas in the same size as an initial state, when a suspicious person appears in the No. 18 image acquisition area, the first processor detects that a first variable of first video data of the No. 18 image acquisition area is larger than a first variable threshold value, the monitoring information image of the No. 18 image acquisition area is amplified, and a first state which is not displayed in other image acquisition areas is output to the display as a monitoring picture, and the monitoring person finds that the No. 18 image acquisition area has the suspicious person to inform local security personnel to go to the area and sends back the drunk suspicious person to the area.
Wherein the at least three image acquisition regions do not have overlapping locations. In other words, the three image capturing devices may be three video surveillance cameras, and three image capturing regions that the three video surveillance cameras can capture do not have coinciding positions.
According to the invention, the at least three image acquisition areas are arranged without repeated covering positions, so that the monitoring camera shooting pictures are ensured not to be repeated, and further more regions can be monitored.
By way of further explanation of the invention, include
All of the first video data contains at least 9 meshes;
a second variable acquisition module for acquiring a second video image frame of the first video data within each second time threshold of each grid and outputting a second variable according to the second video image frames within adjacent second time thresholds of the same grid; the grids with the second variable exceeding the second variable threshold are changed grids, the first variable is the number of changed grids, and the first variable threshold is the number of first grids. According to the invention, through dividing the grids, monitoring personnel can conveniently and accurately observe changed pictures, valuable pictures with large change amplitude are screened for presentation, pictures with small change amplitude are filtered, and the situation of large problems is avoided.
Wherein the second variable of a single grid may be: y is the sum of R, G, B values for each pixel of x video image frames within a single grid in the first video data within a first second time threshold3Y, and the R, G, B value for each pixel of the x video image frames within the single grid in the first video data within the second temporal threshold4In comparison, the first variable may be Y4-Y3Wherein the first second time threshold is adjacent to the second time threshold.
The invention is provided with Y3And Y4So as to convert the picture change in a single grid into a form of comparable data, and further achieve the purpose ofAnd rapidly judging whether the grid is changed.
The number of the first grids is 1-3, and 1 is preferred;
according to the invention, the number of the first grids is set, so that an observation mechanism is triggered when grid change exists, and the identification sensitivity of the system is improved.
Wherein the second variable threshold may be 101～1011Preferably 104。
According to the invention, the second variable threshold is set, so that the change condition of the image picture can be reflected more sensitively under the condition that the grid is not divided.
In other words, if the second variable of one grid is greater than the second variable threshold, the number of grids is changed by + 1.
The invention can judge whether the video monitoring picture has the change of the details more accurately by setting and recording the number of the change grids. The number of meshes of each first video data is preferably 9.
According to the invention, the number of the grids of the first video data is set to be preferably 9, so that the condition of monitoring pictures can be more intuitively reflected, the situation that slight changes are not captured due to overlarge grid division is avoided, and the situation that the reaction is too sensitive due to the change of a single grid is also avoided.
For example: the first video data contains 9 meshes, the second time threshold is 3 seconds, and the first video data outputs video at 60 frames per second. Then the video is displayed at 720p within the grid in the first video data. The R, G, B value of each pixel can be respectively an integer between 0 and 255, wherein the R value of the pixel of the first and second time thresholds is 205, the G value is 36, and the B value is 88. The R value of the pixel of the second time threshold is 151, the G value is 42, and the B value is 19. Y of a first and a second time threshold1Can be as follows: 1920*720*60*(205+36+88). Y of a second time threshold2Can be as follows: 1920*720*60*(151+42+19).
In the step of "all the first video data contain at least 9 grids", the 9 grids may be arranged in the display area corresponding to the first video data in the form of 9 grids, so as to divide the display area of the first video data into 9 complete and average parts.
For further explanation of the present invention, reference is made to FIGS. 1, 2, 4 and 7, which also include
And the second processor is used for converting the first positions of the image acquisition devices of the first video data corresponding to the first-level video data into original positions, converting the first video data corresponding to at least two image acquisition devices closest to the original positions into second-level video data, converting the arrangement modes of amplified display of the first-level video data, amplified display of the second-level image data, display around the first-level video data and non-display of other first video data into a second state, and outputting the second state as a monitoring picture to the display screen.
The first position of the image acquisition device confirmed according to the first video data corresponding to the first-level video data is converted into the original position through the second processor, the occupation ratio of the video pictures of the first-level image data and the second-level image data in the monitoring picture is improved, monitoring personnel are reminded that the change of the first video data is large, the problem possibly occurs in the image acquisition area corresponding to the first video data, according to a plurality of monitoring videos with the nearest original positions, the understanding of the monitoring personnel on the area and the conditions of the area nearby the area is enhanced, the situation that the monitoring images scattered in different areas of the monitoring picture close to the original positions need to be newly searched after the images of the first-level video data disappear is effectively prevented, the monitoring traceability is further improved, and the target loss is avoided.
For example: when no suspicious person enters or exits, the display screen displays images of 20 image acquisition areas with the same size as an initial state, when a suspicious person appears in the No. 18 image acquisition area, the first processor detects that a first variable of first video data of the No. 18 image acquisition area is larger than a first variable threshold value, the monitoring information images of the No. 18 image acquisition area are amplified and concentrated, the monitoring images of the No. 16, No. 17 and No. 19 image acquisition areas near the No. 18 image acquisition area are distributed around the monitoring image of the No. 18 image acquisition area, the monitoring information images of other areas are in a second state of unchanged size and are output to a display, and the monitoring person finds that the suspicious person near the No. 18 image acquisition area notifies local security personnel to go to the No. 18 image acquisition area, when the security personnel drive to the image acquisition area No. 18 but the suspicious personnel are not in the image acquisition area, the monitoring personnel find that the suspicious personnel are in the image acquisition area No. 16 through the secondary video data and inform the security personnel, and finally the security personnel drive to the image acquisition area No. 16 to send the suspicious personnel who are drunk and wandering back to the home.
The secondary video data comprises all first video data near the origin positions corresponding to all the primary video data.
According to the invention, the secondary video data comprises all the first video data near the original point position corresponding to all the primary video data, so that observation is achieved to the maximum extent.
Wherein, the magnification display of the secondary video data is at least 1.5 times, and the magnification is smaller than that of the primary video data.
According to the invention, the amplification display of the secondary video data is at least 1.5 times, and the amplification factor is smaller than that of the primary video data, so that monitoring personnel can pay attention to the condition of the primary video data preferentially.
For further explanation of the present invention, reference is made to FIGS. 1, 4 and 7, which also include
The timing module is used for measuring first time after receiving a timing instruction and zeroing the first time after receiving a zeroing instruction;
a third database for storing a first time threshold;
the third processor is used for judging whether all first variables in the monitoring picture have first video data larger than a first variable threshold value, and if not, outputting a timing instruction to the timing module; if yes, outputting a zeroing instruction to a timing module, judging whether a first variable of the primary picture is larger than a first variable threshold value, and if so, outputting the monitoring picture with the arrangement mode in a second state to the display screen; if the first-level video data is not larger than the second-level video data, converting the second-level video data or the first video data with the first variable larger than the first variable threshold into the first-level video data, amplifying and displaying the first-level video data, amplifying a plurality of second-level image data, displaying the amplified second-level image data around the first-level video data, and outputting the amplified second-level image data to the display screen in a third state in a configuration mode that other first video data are not displayed;
and the fourth processor is used for judging whether the first time is greater than a first time threshold value, outputting all monitoring pictures with the same arrangement mode of the first video data display mode as an initial state to a display screen if the first time is greater than the first time threshold value, and otherwise, not acting.
The method comprises the steps that whether first video data with a first variable larger than a first variable threshold value exists in a monitoring picture is judged through a third processor, if not, it is indicated that no object moves or does not exist in the monitoring picture, the current monitoring picture is kept continuously, and a timing instruction is sent to a timing module; if the first time is smaller than a first time threshold value, first video data with a certain first variable larger than a first variable threshold value exists in the monitoring picture, the third processor sends a zero clearing instruction to the timing module, the first time is cleared, whether the first variable of the primary video data is larger than the first variable threshold value or not is judged, if yes, the monitoring picture with the arrangement mode in a second state is output to the display screen, and then monitoring personnel continue to pay attention to the current situation; if not, the attention necessity of the current primary video data is not high, the primary video data is converted into secondary video data, the secondary video data or the first video data with the first variable larger than the first variable threshold is converted into the primary video data, and the third state is output as a monitoring picture to the display screen, so that the situation that monitoring video which is really changed is continuously attended by monitoring personnel is assisted and reminded, and the mastering capacity of the monitoring personnel on the monitoring picture which is changed in real time is improved.
For example: when no suspicious person enters or exits, the display screen displays images of 20 image acquisition areas with the same size as an initial state, when a suspicious person appears in the No. 18 image acquisition area, the first processor detects that a first variable of first video data of the No. 18 image acquisition area is larger than a first variable threshold value, the monitoring information images of the No. 18 image acquisition area are amplified and concentrated, the monitoring images of the No. 16, No. 17 and No. 19 image acquisition areas near the No. 18 image acquisition area are distributed around the monitoring image of the No. 18 image acquisition area, the monitoring information images of other areas are in a second state of unchanged size and are output to a display, and the monitoring person finds that the suspicious person near the No. 18 image acquisition area notifies local security personnel to go to the No. 18 image acquisition area, when the security personnel drive to the room, but the suspicious personnel are not in the No. 18 image acquisition area, the first variables of the primary video data, the secondary video data and the first video data are unchanged, after 60s, the fourth processor outputs the monitoring picture in the initial state to the display screen, and the monitoring personnel inform the security personnel community that no abnormal condition exists temporarily and the security personnel return to the duty room.
After receiving a zero-returning instruction, returning the first time to zero and timing from zero; and after receiving the timing instruction, starting timing or continuing timing.
The invention enables the timer to return to zero after detecting the change of the picture through the arrangement, ensures that the picture does not return to the initial state, and starts and continues timing after receiving the timing instruction when the picture does not change for a long time, thereby avoiding staying in useless pictures for a long time.
The first time threshold is 10-300 s, and preferably 60 s.
According to the invention, the range and the optimization of the first time threshold are set, so that the monitoring personnel can be helped to return to the overview state under the condition that the video content is not obviously changed, and the monitoring personnel can be prevented from paying attention to the monitoring picture without obvious change for a long time.
The step of determining whether all the first variables in the monitored picture have first video data greater than a first variable threshold includes determining whether all the first variables in the monitored picture have first video data greater than a first variable threshold.
According to the invention, the contents of the primary video data, the secondary video data and the first video data are compared in a front-back sequence, so that the video data with the most observation value is observed preferentially, and the monitoring efficiency is maximized.
