Description

[Technical field]

[0001] This relates to a surveillance system in which multiple cameras are installed within one store. [Background technology]

[0002] Conventionally, there are surveillance systems in which multiple cameras are installed. For example, a digital recording device capable of recording video data from multiple surveillance cameras and displaying each video data in a split screen on a monitor has been disclosed (see Patent Document 1). This digital recording device includes a screen display association unit that associates and sets display position information for each split screen with surveillance camera information corresponding to each split screen based on the video data and display setting information stored in a non-volatile memory; a click information collecting unit that generates click image temporary information for identifying the clicked image based on click information when any video data is clicked and selected from among the multiple video data displayed in a divided manner based on the display setting information, and on the display position information and the surveillance camera information set in the screen display associating unit; and an image selection starting means for determining split screen layout information and camera display size information for an image to be click-selected.

[0003] The temporary click image information is composed of click sequence information and surveillance camera information, and the split screen layout information and camera display size information determined by the image selection starting means are combined with the click sequence information and surveillance camera information and written into a volatile memory as display setting information, and the click-selected image data is split and displayed on the monitor based on the display setting information written into the volatile memory.

[0004] In this conventional digital recording device, the decoder 2 decodes a video signal S1 (for example, a signal in the NTSC format) output from a plurality of surveillance cameras to generate a video signal S2 (for example, a signal in the ITU-R The capture mechanism (capture board 3) converts the video signal S2 into video data S3 in a given image format.

[0005] [Patent Document 1] Patent No. 05920702 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] However, it has been difficult to reliably perform simultaneous monitoring using a monitor and multiple cameras within a single store using a simple and inexpensive system configuration and to efficiently improve vandalism prevention and crime prevention.

[0007] That is, when multiple cameras are installed in a store, the viewing area of ​​each camera is usually divided and each camera is set to monitor a different area. However, when each camera is set in a different area like this, the only way to link the data between the cameras is to rely on time synchronization, so it is necessary to use cameras with unified and precise time adjustment and a terminal for adjusting the synchronization of each data. Simply arranging simple cameras does not meet the conditions for such system functions, and there are limitations on the installation and operating costs of a security system that can be built in one store.

[0008] Furthermore, in stores where back-of-store surveillance is not possible, such as when there is no back-of-store space to install surveillance monitors or when it is not possible to assign back-of-store surveillance staff, the monitors are installed inside the store, which means that the monitored content is exposed inside the store, and crime prevention can be compromised by tampering such as changing the monitor's position or obstructing visibility of the monitor.

[0009] Therefore, the objective of the present invention is to provide an in-store surveillance system that can reliably perform simultaneous monitoring using monitors and multiple cameras within a store with a relatively simple and inexpensive system configuration, and can efficiently improve vandalism prevention and crime prevention. [Means for solving the problem]

[0010] In order to solve the above problems, the following measures have been taken. Note that the numbers or combinations of numbers and letters written after each term described below are reference symbols for the convenience of referring to the drawings shown as examples, and do not themselves limit the concept or form.

[0011] [1] The in-store surveillance system of the present invention comprises: One monitor (1D) with a 3 or more element arm-type fixture mounting structure; A plurality of cameras (21C, 22C, ...) each having a clip-type fixing structure; A monitoring system comprising a monitor with a microphone and a data processing unit for processing audio data and image data of a camera with a microphone, each of which is installed in a plurality of positions or a plurality of directional ranges on at least one fixed fixture in a store, In the data processing unit, the data acquired by the multiple microphone-equipped cameras (21C, 22C) is composed of a data set including at least image, sound, and time data; The data acquired by the microphone-equipped monitor is a data set including at least sound and time data, In the data processing unit, a plurality of data (e.g., at least one of sound and time) included in the acquired data are linked as auxiliary data to the parent data of the one microphone-equipped monitor based on a common element of each of the data, The monitor with microphone is characterized in that it can simultaneously display the data acquired by each camera with microphone, which has been linked by the data processing unit, within the same display range as the data acquired by the monitor with microphone.

[0012] The above means fixes a monitor with a microphone and at least one camera with a microphone to at least one fixed fixture in the store, and makes it possible to acquire a data set including at least sound and time from each acquired data. The acquired data is then linked with common elements of multiple data including sound and time, thereby improving the maintenance of the security surveillance state. In particular, by providing the monitor with a microphone with an arm-type fixture fixing structure with three or more elements, the viewing angle of the monitor can be adjusted to any value regardless of the fixed position to the fixed fixture FP, and the distance, angle, or positional relationship from the camera with a microphone can be adjusted to any value.

[0013] In addition, the monitor camera simultaneously displays the linked related data in a row (Fig. 4 or Fig. 5b). Even if an abnormality occurs, such as the fixed position being changed or the acquisition of each data being blocked by tampering, the abnormality can be easily detected by the disturbance of the row display.

[0014] [2] In the in-store surveillance system, One monitor with microphone (1D) equipped with a 3 or more element arm-type fixture structure, A plurality of cameras with microphones (21C, 22C, ...) equipped with a clip-type fixing structure; A monitoring system comprising a monitor with a microphone and a data processing unit for processing audio data and image data of a camera with a microphone, each of which is installed at a plurality of positions or in a plurality of directional ranges within a store, The data processing unit processes the data acquired by the multiple microphone-equipped cameras (21C, 22C) as auxiliary data to the parent data of the one microphone-equipped monitor, based on common elements of the video or audio data of each data, The monitor with microphone is characterized in that the data acquired by each camera with microphone, which has been linked by a data processing unit, can be displayed side by side within the same display range as the associated acquired data of the monitor with microphone.

[0015] The above is a process of linking a camera with a microphone (Fig. 1) with a monitor with a microphone. For example, in Fig. 4, image data from one camera with a microphone 21C closest to the monitor is displayed as parent data in the F: front display frame, and image data from another camera with a microphone 22C is displayed side by side as accessory data in the B: back display frame. The parent data is displayed in the specified display frame, and the camera of the accessory data can be switched and selected for display.

[0016] [3] The data processing unit identifies continuous or intermittent sound data variability of each sound data, detects common elements in the sound data variability between the monitor and each camera, links the ancillary data based on these common elements, and stores or displays combined data that combines the parent data and the ancillary data.

[0017] The above is a process of linking related data together (Fig. 4 or Fig. 5b) based on common elements of sound data. In other words, frequency fluctuations in sound data acquired by a monitor should appear as common fluctuations accompanied by a certain degree of attenuation even in sound data acquired by a camera in the same store. Based on the premise that the cameras are installed in close proximity within one store and on the common principle of the above-mentioned variability, data is linked by sound data. The above means eliminates synchronization errors due to time settings and camera data processing time.

[0018] [4] At least one of the plurality of cameras acquires image data including any one of different data formats, such as PAL, NTSC, and 720P / Nor infrared; The data processing unit is characterized in that, by using an add-in processing structure built into the expansion space, the video data of the different data formats are integrated (coded) as video data of the same image type as the video data of the monitor, and all video data are stored and processed as data linked to the audio data of the monitor.

[0019] The above is a process for linking different types of video data together (Fig. 4 or Fig. 5b). For example, even when different display formats such as PAL, NTSC, and 720P / Nor infrared are adopted for each camera and different types of cameras are used in combination, synchronization can be easily performed by using the linking by sound data as a standard in [3] above. In the embodiment, the data are classified (by position and type) and are controlled for synchronization. Priority is given to linking elements in the following order: common elements of sound data > common elements of image data > common elements of time data.

[0020] In this embodiment, each data is divided into video data IM, audio data SO, identification information ID, and attachment information ATT, and all video data is stored as a group of still image data linked to the monitor's video data. The audio data at the time of acquisition is synchronized as an audio data structure specified by a reference time, and the related data with a synchronization tag attached is stored in a state that can be linked to the monitor's parent data.

[0021] [5] The data processing unit is characterized in that if it cannot detect a common element between the data or if an operational error occurs, it combines the integrated data as abnormal data and displays an alert on the monitor.

[0022] The above will alert you to a matching error (Figure 5a).

[0023] [6] The fixture fixing structure is characterized in that the hinge angle of hinges 11AH, 11BH is fastened and fixed or the adjustable connection length is fixed circumferentially between clamping fixing part 1J to fixture FP and monitor mounting plate 1PT via three elements, first arm part 11A, first arm part 11B, and adjustment arm part.Furthermore, it is characterized in that a switch is energized to the lock mechanism in the connected state to detect the release or loosening of the connection.

[0024] The above specifies the mounting structure and theft prevention mounting status sensor (Figs. 2 and 3). Effect of the Invention

[0025] The above-mentioned means makes it possible to provide an in-store surveillance system that can reliably perform simultaneous surveillance using a monitor and multiple cameras within a store using a relatively simple and inexpensive system configuration, thereby efficiently improving vandalism prevention and crime prevention.

[0027] <System configuration> The present invention is a surveillance system in which each component is installed in multiple positions or multiple directional ranges within one store, and includes one monitor (1D) equipped with an arm-type fixture fixing structure with three or more elements; A plurality of cameras (21C, 22C, ...) each having a clip-type fixing structure; It is composed of a monitor with a microphone and a data processing unit that processes audio data and image data from a camera with a microphone.

[0028] <System Overview> System configurations consisting of separate or auxiliary components: The in-store surveillance system of the present invention comprises an arm-mounted monitor with microphone 1D and multiple clip-mounted cameras with microphones 21, 22, ..., each of which continuously or intermittently acquires audio data 21SO, 22SO... by its own microphone, simultaneously with image data 21IM, 22IM, ... acquired by the camera.

[0029] Furthermore, the monitor 1D with microphone also continuously or intermittently acquires the audio data 1SO acquired by its own microphone, and displays the image data acquired by any one or more cameras on the monitor 1D.

[0030] The monitors and cameras of the in-store surveillance system of the present invention are fixed to multiple locations on a fixed fixture FP within a store using an arm fixing structure or a clip-type fixing structure, as shown in FIG. 3 or FIG.

[0031] As the fixing structure, the arm of the monitor with microphone and the clip of the camera with microphone each comprise a fixing structure including a movable part for fixing to a fixed part such as a fixture in a store or a wall, floor, or ceiling in a room, and an anti-theft attachment is additionally attached to each movable part. Also, at least one camera clip of the multiple cameras with microphones comprises a monitor-attached clip structure 21J that can be attached to and fixed on the monitor with microphone 1D, and as shown in Figures 2 and 3, a configuration can be adopted in which a camera with microphone 21C is attached to the side end of the display frame of the monitor with microphone 1D.

[0032] <Overview of each processing section> During camera monitoring operation, each camera periodically acquires data sets 21DS,dd22DS,23DS,... consisting of a data group of acquired image data 21M (or 22M, 23M,...) acquired continuously or intermittently at set unit time intervals, a data group of acquired voice data 21SO (or 22SO, 23SO,...) acquired continuously or intermittently at set unit time intervals, and an identifier ID of each camera individually set, and mounting status data ATT consisting of mounting time and / or mounting position data (Fig. 1). Of these, the acquired image data and acquired voice data are processed in association with each other according to the time of data acquisition.

[0033] In addition, the acquired image data and acquired audio data are compressed by differential processing into a data group consisting of multiple consecutive data for each set time, and the oldest data included in the data group is automatically deleted as new data is acquired, and the data group is updated as time passes.

[0034] Each time the data set 21DS, 22DS,... of each camera is compressed, it is sent by wire or wirelessly to a memory unit of a data processing unit provided in a separate processing terminal. In Fig. 1, it is automatically sent to a memory unit attached to the monitor, and is processed as display data by a data processing unit built into or attached to the monitor.

[0035] In addition, when a camera is directly attached to the end of the monitor as in Figure 2 or Figure 3, the data set captured by the camera attached to the monitor is stored in memory as data set 12RDS for data processing on the monitor, in a memory structure separate from the data sets captured by other cameras (Figure 1).

[0036] The data acquired by the multiple microphone-equipped cameras (21C, 22C, ...) is linked by a data processing unit attached to the monitor as ancillary data to the parent data of the single microphone-equipped monitor, based on the commonality of one or more elements of each data, such as image, sound, and time.

[0037] The monitor with microphone is characterized in that the data acquired by each camera with microphone, which has been linked by a data processing unit, can be displayed side by side within the same display range as the data acquired by the monitor with microphone, which is linked to the data.

[0038] (Camera with microphone (Figure 1)) One monitor with microphone (1D) equipped with a 3 or more element arm-type fixture structure, A plurality of cameras with microphones (21C, 22C, ...) equipped with a clip-type fixing structure; The components, which are comprised of a monitor with a microphone, a data processing unit for processing audio data and image data from a camera with a microphone, are installed in a plurality of positions or a plurality of directivity ranges within the store.

[0039] The one monitor with microphone continuously stores a group of acquired image data attached to the monitor or closest to the monitor as parent image data 1IM as a data set of parent data, and also continuously stores a group of sound data acquired by the monitor's microphone as parent sound data 1SO. Furthermore, the individual ID of the monitor is stored in advance, and after the monitor is installed and fixed in the store, the installation status information ATT of the monitor is stored and stored in an accessible memory structure of the data processing unit as the monitor's parent data set 12RDS.

[0040] In addition, the data acquired by the multiple microphone-equipped cameras (21C, 22C) is transmitted as each data set to a data processing unit built into the monitor at regular time intervals and is overwritten and saved in the memory unit built into the monitor. At this time, based on the commonality of data fluctuations between the sound data in the data set of the parent data or the compressed data consisting of the sound data and image data, the data set of each camera is linked as auxiliary data to the parent data of the one microphone-equipped monitor.

[0041] For example, the characteristics of identifiable peak sound (high-pitched or loud sound) data and the peak sound data one or two frames before and after it contained in the continuous image data or sound data of each data group are picked up and used as common elements. When an identifiable sound occurs in a store, such as an object falling, a customer entering or leaving, an in-store announcement, or a security alarm sound, this sound data and the sound data before and after it are linked based on the data characteristics and fluctuation amount of the data set including the data.

[0042] The monitor with microphone is also characterized in that the data acquired by each camera with microphone, which has been linked by a data processing unit, can be displayed side by side within the same display range as the data acquired by the monitor with microphone, which is linked to the data.

[0043] For example, in Fig. 4, image data from one camera with microphone 21C closest to the monitor is displayed as parent data in a front display frame F, and image data from another camera with microphone 22C is displayed in parallel as accessory data in a back display frame B. The parent data is displayed in the specified display frame, and the camera of the accessory data can be switched and selected for display.

[0044] Also, for example, in FIG. 5, the display section 12F of the front data 12ID on the left side of the display section plays and displays continuous image data of one data set from a specified camera with a microphone, which is one of the child data, and which is installed in a position separate from the monitor, and the display section 12F of the back data 12ID on the right side of the display section plays and displays continuous image data of the camera with a microphone attached to the monitor, which is the parent data, after synchronous processing.

[0045] (Linking related data using sound data (Figure 4 or Figure 5b)) The data processing unit identifies continuous or intermittent sound data variability of each sound data, detects common elements in the sound data variability between the monitor and each camera, links the ancillary data based on these common elements, and stores or displays combined data that combines the parent data and the ancillary data.

[0046] Frequency fluctuations in sound data acquired by monitors should appear as common fluctuations accompanied by a certain degree of attenuation in sound data acquired by cameras in the same store. Based on the premise that the monitors are installed in close proximity within a single store and on the common principle of variability, data is linked by sound data.

[0047] This eliminates misalignment due to time settings and camera data processing time. For example, even if multiple display formats such as PAL, NTSC, and 720P / Nor infrared are used in combination with multiple image data formats, the synchronization process becomes easier by using the linking based on this sound data.

[0048] In the embodiment, the elements are classified (by position and type) and controlled for synchronization. The elements are prioritized in the following order: common element of sound data > common element of image data > common element of time data.

[0049] (Linking different video data (Fig. 4 or Fig. 5b)) At least one of the multiple cameras acquires video data including any of different data formats such as PAL, NTSC, or 720P / Nor infrared, The data processing unit is characterized in that it integrates (codes) the video data of the different data formats as video data of the same image type by using an add-in processing structure built into the expansion space.

[0050] For example, Fig. 8(a) shows the screen when the setting button CIB is selected on the screen for switching and setting the camera's image data format, and Fig. 8(b) shows the dialogue screen when selecting one of the camera's image data formats from the selection dialogue of 720P, 1080P, 720N, and 1080N. Apart from the process of linking parent data and child data in the data processing unit, the data format of the acquired data in each camera is set individually, and the add-in processing of the processed data format is performed when displaying the data on the monitor screen, replacing the display processing.

[0051] (Linking error alert (Figure 5a)) The data processing unit is characterized in that if it cannot detect a common element between the data or if an operational error occurs, it combines the integrated data as abnormal data and displays an alert on the monitor.

[0052] In this embodiment, each data has a data structure of video data IM, audio data SO, identification information ID, and attachment information ATT.

[0053] (Installation structure for fixtures / anti-theft (Fig. 2, 3)) The fixture fixing structure is characterized in that the hinge angle of hinges 11AH, 11BH or the adjustable connection length is fastened and fixed or circumferentially fixed between the clamping fixing part 1J to the fixture FP and the monitor mounting plate 1PT via three elements, namely, first arm part 11A, first arm part 11B, and adjustable arm part.

[0054] As shown in Figures 1 to 4, the fixture fixing structure for a monitor with a microphone is composed of a clamping fixing part 1J to the fixture FP and a monitor mounting plate 1PT, and is configured to fasten and fix the hinge angle of hinges 11AH, 11BH or to fix the adjustable connection length around the periphery via three elements: first arm part 11A, first arm part 11B, and adjustable arm part.

[0055] A predetermined angle is fixed between the first arm portion 11A and the second arm portion 11B by the hinge 11AH, and the arm length and the protruding angle of the spherical hinge 11DH are fixed between the second arm portion 11B and the adjust arm portion 11C by setting the insertion amount of the second arm portion 11B into the cylindrical elastic circumferential attachment part of the adjust arm portion and the circumferential attachment of the elastic circumferential attachment part, and by tightening the handle 11CH that adjusts the circumferential attachment force of the elastic circumferential attachment part. The spherical hinge 11DH incorporates a ball with an axle in the spherical cap, and the axle of the ball with an axle protruding from the cap groove can be set in any direction.

[0056] A fixed plate 1PT is connected to the tip of the spherical hinge 11DH with a ball hinge. These hinge arms are fastened and fixed to a pillar FP or a table FP1 of a store fixture by a fastening joint 1J via a base hinge 11JH as shown in Figure 3 or Figure 4. In order to store the arm orientation and hinge angle in the connected state as shown in Figures 3 and 4 as the attached state, an oval hole is provided in each arm, and a gyro sensor 11R is attached to this oval hole. Also, a switch is energized in the locking mechanism.

[0057] As a result, the arm angle and the inclination of the arm surface in the installed state are stored, and the angle of the hinge adjustment handle adjusted with the dial is stored, and is converted into data and stored as attachment information data ATT. This attachment information data ATT is stored by setting data in the installed state, and is transmitted at each presentation interval while being included in the data sets 21DS, 22DS, ... of each camera. Also, by setting data again, it is possible to detect differences from the previous data memory.

[0058] <System processing operations> Operation 1: Audio synchronization and classification: The audio data from the monitor and camera are classified (by location and type) and synchronized, and integrated data / video is output in a form that corresponds to each classification of type and location. Operation 2: If an abnormality is detected according to the conditions, an alert signal will be output and output as sound or light from the camera or monitor.

[0059] FIG. 5a shows an example of a full screen display with two-split display as an example of a playback screen of data in memory that has been subjected to the linking process. The entire display screen is divided into two, left and right, and images captured by each camera are displayed in real time on the display screens of the front display section 12F and the rear display section 12B. The home button HB is always displayed on the right edge of the rear display section 12B, and the zoom adjustment button for the angle of view is always displayed above it. During alert, images captured by the two set cameras can be displayed in real time with this two-split display.

[0060] FIG. 5b shows an example of a playback screen of data in the memory that has been subjected to the linking process. By going back to a past time displayed in the time display section 14T on the left side of the screen and selecting the playback button 14L or the back or forward button 141 on the bottom left of the screen, the animation icon 14S indicating the action playback moves with a predetermined animation action, and is played back in the display section 12 from the center to the right of the screen. In FIG. 5b, the display section 12 has a left and right split display screen of a front display section 12F and a back display section 12B, and the motive data is displayed on these split display screens. If there is only audio data, the display section is not displayed, and only the animation icon 14S on the left side moves.

[0061] In addition, at the bottom of the display unit 12, a selection button AI for the sound data AID of the monitor with microphone, which is the parent data, and selection buttons 121, 122, 123, and 124 for the image-accompanying sound data 1ID, 2ID, 3ID, and 4ID of the four child data of the first to fourth cameras with microphones, which are displayed side by side, are horizontally separated and displayed. By a selection setting operation, it is selected which continuous image is to be played back as a video on the front display unit 12F and the back display unit 12B, respectively, and the continuous image data is displayed in a state of audio synchronization.

[0062] <Summary of the invention including examples> The present invention is characterized by the separate installation of multiple cameras linked to one monitor within a single store.

[0063] A monitor with a microphone and cameras 21, 22 (23, 24) are fixed to a fixture in the store and are configured separately (by position, type, etc.) to perform an identification process. Another feature of this system is the arrangement of integrated display methods, switching methods, and monitoring methods that utilize two camera images.

[0064] For example, when displaying the cashier's area including the cashier's hands and a wider area of ​​the store including this area in a synchronized manner, the recording time is adjusted based on the monitor's audio data as a synchronization setting.

[0065] Another feature of this system is that it combines multiple cameras of different types (methods, angles of view, functions) and processes them synchronously.

[0066] Furthermore, the camera 2 can be replaced with a version with a different function and combined. For example, even if an infrared camera (night vision camera), a camera with a motion sensor (automatic start recording), and a panoramic (wide-angle) camera are combined, they are saved as a group as a continuous data set of still data, and a linking tag to the parent data is attached and saved. This makes it easy to link different types of image data.

[0067] It is also characterized by its ability to switch to other video formats (wide-angle: PAL format, NTSC format, 720P / Nor infrared display format) / expand processing methods by combining combination processing units, data integration of multiple formats, and compressed display.

[0068] Furthermore, the present invention is characterized in that the power supply state is managed and controlled when different power supply methods are combined.

[0069] For example, a store's surveillance and crime prevention monitoring system can be equipped with a combination of a general-purpose tablet, mini camera, arm, clip, and processing unit, allowing for expandable processing and display functions.

[0070] The present invention is not limited to the configurations of the above-described embodiments, and various combinations, substitutions, and extraction of parts of the configurations are possible. [Explanation of symbols]
