[0014] FIG. 1 shows a configuration diagram of a CCTV event statistics device according to one embodiment.

[0015] Referring to FIG. 1, a CCTV event statistics device (100) according to one embodiment may include an input device (110), a display device (120), a communication module (130), a memory (140), and a processor (150). In one embodiment, some components of the CCTV event statistics device (100) may be omitted, or additional components may be included. Additionally, some of the components of the CCTV event statistics device (100) may be combined to form a single entity, while performing the same functions as the components prior to combination. Furthermore, the CCTV event statistics device (100) may be composed of multiple devices. For example, the CCTV event statistics device (100) may be composed of a control center terminal and a server device.

[0016] The input device (110) can receive user input using the CCTV event statistics device (100). The input device (110) may include at least one input detection circuit, for example, a button, a touchscreen, or a microphone.

[0017] The display device (120) can visually output at least one data of a symbol, a number, or a character under the control of the processor (150). The display device (120) may include, for example, at least one display device among a liquid crystal display, an OLED, and a touchscreen display.

[0018] The communication module (130) can support the establishment of a communication channel or a wireless communication channel between the CCTV event statistics device (100) and other devices (e.g., a plurality of CCTV terminals (19)), and the performance of communication through the established communication channel. The communication channel may include, for example, at least one communication channel among LAN, FTTH, xDSL, Wibro, Wireless LAN, Wi-Fi, Bluetooth, Zigbee, WFD (Wi-Fi Direct), UWB (Ultrawideband), Infrared Data Association (IrDA), BLE (Bluetooth Low Energy), NFC (Near Field Communication), 3G, 4G, or 5G.

[0019] The memory (140) may include various forms of volatile or non-volatile memory. For example, the memory (140) may include ROM (read only memory) and RAM (random access memory). In one embodiment, the memory (140) may be located inside or outside the processor (150), and the memory (140) may be connected to the processor (150) through various known means. The memory (140) may store various data used by at least one component of the CCTV event statistics device (100) (e.g., the processor (150)). The data may include, for example, input data or output data for software and related commands. For example, the memory (140) may store at least one instruction and data for providing CCTV event statistics services.

[0020] The processor (150) can control at least one other component (e.g., a hardware or software component) of the CCTV event statistics device (100) and can perform various data processing or operations. The processor (150) may include, for example, at least one of a central processing unit (CPU), a graphics processing unit (GPU), a microprocessor, an application processor, an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA), and may have multiple cores.

[0021] According to one embodiment, the processor (150) may provide a user interface for setting at least one of a display channel, a display event, or a display time through a display device (120). The user may set or change at least one of a display channel, a display event, or a frequency display method through the user interface and an input device (110).

[0022] The above events may be multiple events related to at least one of an incident, accident, disaster, or calamity. The above events may include, for example, at least one type of safety accident event among an explosion, collapse, fall, collision, intrusion, fire, or flooding.

[0023] The above expression time may include a statistical period and a statistical period. The above statistical period may be a designated time interval such as one hour, time zone, day, week, or month. The above statistical period may be a period to be statistically processed (a period to be configured as a graph). The above expression channel is a CCTV channel to be configured as a three-dimensional graph among a plurality of CCTV channels, and may be set, for example, at the CCTV terminal unit (e.g., individual CCTV channel unit regardless of group) or at the group unit (e.g., CCTV channel belonging to the first group). The above frequency expression method may set whether to express the occurrence frequency in the form of a frequency value for each time zone, a total cumulative value, an absolute value, or a relative value. The above relative value may be calculated, for example, as the ratio (e.g., percentage) of the occurrence frequency of the remaining events compared to the occurrence frequency of a reference event. The above reference event may be set through an input device (110).

[0024] According to one embodiment, the processor (150) can receive multiple CCTV videos in real time from multiple CCTV terminals (19) using a communication module (130). The processor (150) can analyze the multiple CCTV videos to determine whether multiple types of events have occurred. For example, the processor (150) can analyze the multiple CCTV videos to determine that three types of events—explosion, collapse, and collision—occurred a total of 19 times (2 times, 10 times, and 7 times, respectively) from 1:00 AM to 2:00 PM on November 1, 2024, on the first CCTV channel (ch1).

[0025] According to one embodiment, when the processor (150) detects the occurrence of an event in a CCTV video, it can store event analysis data including information on the type of the detected event, information on the channel of occurrence, and information on the time of occurrence in the memory (140).

[0026] According to one embodiment, when the processor (150) obtains a user’s statistical information request through the input device (110), it can check the currently designated expression channel, expression event, expression time, and frequency expression method. The designated expression channel, expression event, expression time, and frequency expression method may be set by the user through the input device (110) or may be set by default in the CCTV event statistics device (100).

[0027] The processor (150) can obtain event analysis data for a statistical period from the memory (140) and, based on the event analysis data, calculate the frequency of occurrence of expression events by CCTV channel that occurred in the expression channel in statistical cycle units.

[0028] According to one embodiment, the processor (150) can construct a three-dimensional graph of the frequency of occurrence of a representation event by CCTV channel in statistical cycle units. For example, the processor (150) can construct a three-dimensional graph with time on the x-axis, channel type on the y-axis, and frequency of occurrence on the z-axis. In this case, the processor (150) can construct a three-dimensional bar graph with the frequency of event occurrence as the height.

[0029] According to one embodiment, the processor (150) can display the configured three-dimensional graph through the display device (120).

[0030] According to one embodiment, the processor (150) can obtain a change-designation input for a representation event through an input device (110) after outputting a three-dimensional graph. The processor (150) can check the change-designated (changed) representation event and calculate the frequency of occurrence per CCTV channel for the changed event in statistical cycle units based on event analysis data. The processor (150) can configure a three-dimensional graph based on the frequency of occurrence per CCTV channel for the changed event in statistical cycle units. For example, while the processor (150) is calculating the frequency of occurrence per CCTV channel for an 'explosion' event in one-hour units and displaying it as a three-dimensional graph, it can check for a user input that changes the representation event to a 'collision' event. In this case, the processor (150) can recalculate the frequency of occurrence per CCTV channel for the changed 'collision' event in statistical cycle units based on event analysis data and configure and display a three-dimensional graph based on the recalculation result.

[0031] According to one embodiment, the processor (150) can obtain a reassignment input of the statistical period through the input device (110). The processor (150) can check the changed statistical period and recalculate the frequency of occurrence of the event by CCTV channel in the changed statistical period unit based on event analysis data. The processor (150) can construct a three-dimensional graph of the frequency of occurrence of the event by CCTV channel in the changed statistical period. For example, while the processor (150) is displaying the frequency of occurrence of the event by CCTV channel in the hourly unit as a three-dimensional graph, it can check for a user input that changes the statistical period to a daily unit. The processor (150) can recalculate the frequency of occurrence of the event by CCTV channel in the daily unit based on event analysis data and construct and display a three-dimensional graph based on the recalculation result.

[0032] According to one embodiment, the processor (150) may obtain a reassignment input of the frequency expression method through the input device (110). The processor (150) may check the changed frequency expression method and, based on event analysis data, recalculate the frequency of occurrence per CCTV channel using the changed frequency expression method and construct a three-dimensional graph based on the recalculation result. For example, while the processor (150) is displaying the frequency of occurrence per CCTV channel for each statistical period as a three-dimensional graph, it may check a user input that changes the frequency expression method to a relative value relative to a reference CCTV channel through the input device (110). The processor (150) may check the reference CCTV channel set according to the user input, calculate the ratio (e.g., percentage) of the relative event occurrence frequency relative to the reference CCTV channel based on event analysis data, and construct and display a three-dimensional graph based on the recalculation result. Similarly, the user may set a reference event or a reference point in time through the input device (110). The processor (150) can calculate the frequency of events per CCTV channel relative to a reference event or reference point in time, and can configure and display the relative values ​​of time, CCTV channel, and event frequency as a three-dimensional graph.

[0033] According to one embodiment, the processor (150) may continue to configure and display a three-dimensional graph until it obtains a request to terminate the application through the input device (110).

[0034] According to various embodiments, the processor (150) can control the communication module (130) to selectively receive CCTV images from individual CCTV channels or CCTV channels of a group (e.g., a first or second group) selected among a plurality of CCTV channels. For example, the processor (150) can provide the communication module (130) with a communication address (e.g., an IP address) of a first group or a second group that is set or changed, or set as default, through the input device (110), and can selectively receive CCTV images from the CCTV channels of the group according to the provided communication address.

[0035] According to various embodiments, the processor (150) provides a user interface capable of setting one of a plurality of graph forms, and can configure the three-dimensional graph in the default or through the user interface the set graph form. The setting of the graph form may include, for example, at least one of graph color mapping by representation target (e.g., representation color by channel / event) or changing the axis of the representation target (e.g., x-axis → y-axis).

[0036] According to various embodiments, the processor (150) may not include a function for analyzing CCTV images from CCTV channels. In this case, the processor (150) may acquire event analysis data that has been analyzed and stored by another intelligent video analysis device and perform the statistical processing and three-dimensional graph construction described above based on the acquired event analysis data.

[0037] In this way, a CCTV event statistics device (100) according to one embodiment can provide event analysis data to a control center operator in the form of a three-dimensional graph, based on a designated statistical period, expression event, expression target CCTV channel, and frequency expression method for CCTV images analyzed in real time.

[0038] Furthermore, the CCTV event statistics device (100) according to one embodiment provides a three-dimensional graph that allows event analysis data to be easily understood, thereby supporting the operator to intuitively identify and decide on events to intensively monitor or control by CCTV, which reduces the operator's fatigue and increases control efficiency.

[0039] FIG. 2 is an example diagram of a user interface for displaying CCTV video analysis results according to one embodiment.

[0040] Referring to FIG. 2, the CCTV event statistics device (100) can display a three-dimensional graph with time on the x-axis, channel type on the y-axis, and occurrence frequency on the z-axis through a user interface.

[0041] The CCTV event statistics device (100) can display a display event change menu (210), a display channel change menu (220), a display time change menu (230), and a frequency display method change menu (240) through a user interface. The CCTV event statistics device (100) can change the display event, display channel, display time, or frequency display method according to the menu settings by the user among the menus (210, 220, 230, 240).

[0042] The CCTV event statistics device (100) may additionally provide previous and subsequent time movement buttons (251, 252). If the statistical cycle is short compared to the statistical period (display time) and the 3D graph exceeds one page of the user interface, the CCTV event statistics device (100) may selectively provide a 3D graph of the previous time and a 3D graph of the subsequent time depending on the selection of one of the previous and subsequent time movement buttons (251, 252).

[0051] In operation 450, the CCTV event statistics device (100) can monitor whether user input is received.

[0052] In operation 450, when it is confirmed that user input has been received, the CCTV event statistics device (100) can recalculate the frequency of event occurrence per CCTV channel according to the user-inputted change setting among the expression channel, expression event, expression time, or frequency expression method in operation 460.

[0053] In operation 470, the CCTV event statistics device (100) can configure and display the frequency of events per CCTV channel in a recalculated statistical cycle unit as a three-dimensional graph.
