CCTV is installed and operated for various purposes such as crime prevention, surveillance, management and control in order to overcome the limitations of supervision and supervision by manpower. For example, when CCTV is not available, On the other hand, nowadays, it is possible to remotely monitor incidents and accidents that occur in the alleys with a minimum of manpower in a centralized control center through a security camera.

Furthermore, as the recording equipment developed, it became possible to store the moments that the monitor missed for a long time, and also to be able to grasp the problem situation relatively quickly after the problem occurred.

However, as the effectiveness of CCTV has been verified in various sites, the number has increased explosively and now it has been installed and introduced into various places in the premises where facilities exist.

Paradoxically, as the number of CCTVs increases, the efficiency of the supervisor increases simultaneously. As a result, after the awareness of the occurrence of the problem, it becomes a structure that can respond to incidents and accidents based on the recorded images. The problem is that if you can not pinpoint the time and location of the problem when you check the recorded video, the time it takes to acquire the evidence is dramatically increased.

For example, if a passenger of a specific day is selected and checked only by a person other than the worker, it is difficult to confirm all the images from the opening time to the closing time of the entrance of the day.

Even if all the access information is databaseed through the access control device by introducing the security equipment, it is inevitable to check the list of the access times on the day and input the corresponding time into the direct recording device to collate.

Furthermore, when the clock set in the CCTV recorder is out of the clock set in the access control device, the accessing information acquired through the access control device deviates from the image recorded in the recorder.

On the other hand, various computer systems introduced for the management and supervision of the facilities perform functions to record and store important and various events occurring in the facilities as numerical information.

For example, access control devices record access information, and similar record information is applied to the entry and exit and entry and exit management areas within the logistics management system used in distribution centers.

In addition, at the bank's receipt window, the entire process of issuing and storing the slip is recorded through ERP (or MIS). The point-of-sale management system of the retail outlet stores the point of time of sale and the point of time of delivery, The facility management system records monitoring information on facilities such as water supply and sewerage, gas, oil, and ventilator, and factory automation (FA) records information input from various measurement equipment for quality control.

These computerized systems include proprietary information processing methods to manage events, accidents, problems, and quality based on the already quantified records. However, although CCTV is already installed in order to supplement important monitoring and management targets, a tool for integrating them together is not provided.

The reason for this is that the database handled by the computer system described above contains information that requires very high reliability from the viewpoint of the user side, and since the DB processing method has a long experience and know-how of each solution provider, There is a restriction that it can not be disclosed to a specialist in a solution or a video control system or can not be handled by the processing method.

In addition, CCTV solution specialists are also faced with the complaint that designing a DB that meets the purpose of managing individual facilities, which are sufficiently complicated and heavy, for each combination of CCTV and DB, It is physically impossible.

Based on the contents of this specification.

Hereinafter, an event-based image comparison management system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram illustrating a configuration of an event-based image comparison management system according to an embodiment of the present invention.

In the description of the present invention, among the information recorded according to each requirement recorded in various computerized management systems, an event, an accident, and a time when a problem occurs Are collectively referred to as an " event ".

As shown in FIG. 1, the event-based image comparison management system according to the present invention includes a function of transmitting a query to an event DB server to acquire event information to be confirmed as an image in a terminal or a server including the image comparison management module, An event DB server 100 having a function of transmitting the response of the event type, the characteristic, the channel position, and the time information of the event at the event DB server to a terminal or a server including the image comparison management module; A function of listing event information so that only desired event information can be selected from the type, characteristics, channel location, and time information at the time of occurrence of an event received from the event DB server; A function of extracting viewpoint related information and inputting it to the OCX module, a function of requesting and sending a streaming image from the time of occurrence of the event to the end of the event to the digitalized recording device (DVR) A terminal or server 200 including a video comparison management module having a function of reproducing a streaming video received from a DVR; In order to secure event information that occurs in video management, process management, slip management, access control management, and logistics management, a computerized management system is installed at a position to be managed, and event images are taken A CCTV (300) having a function; A function of receiving, recording, and recording an event image photographed from the CCTV; and a function of receiving a streaming image from a terminal or a server including the image comparison management module until the end of the event, A digitalized recording device (DVR) 400 having a DVR firmware; A function of dynamically recording an external IP and a communication port in which the corresponding DVR is located when the digital recording device (DVR) accesses the dynamic address management server through the execution of the DVR firmware from time to time, A dynamic address management server 500 having a function of transmitting and receiving external IP information through the DVR and the communication port; Respectively.

The function of each technical means constituting the event-based image comparison management system of the present invention will be described as follows.

The event DB server 100 has a function of transmitting a query to an event DB server 100 to acquire event information to be confirmed as an image in a terminal or a server 200 including an image comparison management module, And transmits the response of the event type, characteristic, channel position, and time information at the time of occurrence to the terminal or the server 200 including the image comparison management module. Here, the event DB server 100 plays a role corresponding to a DB server of a computerized management system that performs video management, process management, document management, access control, and logistics management.

The terminal 200 including the image comparison management module or the server 200 may store event information in order to select desired event information from the type, characteristics, channel location, and time of occurrence of the event received from the event DB server 100 And a function of extracting information related to a time point of occurrence and an end point of the event selected from the event list and inputting the information to the OCX module 210; And a function of playing back the streaming image received from the DVR 400, which is digitized by the OCX module 210. The OCX module 210 receives the streaming video from the DVR 400,

In addition, the above-mentioned OCX (OLE control extension) means that various computer management systems to which an event-based image comparison management system is to be introduced are classified into a development platform and a program by a variety of factors such as scale, network structure, security policy, The language is very diverse. If there is no universality, the OCX method is selected because commercialization is not possible in accordance with the purpose of the present invention.

Before you can understand the concept of OCX, you need OLE (Object Linking and Embedding), a powerful software integration tool from Microsoft.

It is the link and insertion of an object that literally translates the abbreviation notation, that is, OLE is a convention to make it easy to link or insert data in an application.

OCX is a user control written in OLE, that is, a kind of program module, which can be used on any platform under the Windows operating system.

By introducing the OCX method, a computer management system company specialized in DB management and measurement equipment control can introduce the function without having to research and develop a heterogeneous and deep technology for image control and processing for a long time.

In addition, creating, processing, and processing point-in-time information on various management points defined as event DBs is a task that management solution companies have been continuously doing, and they have finished results. The third solution, which integrates the CCTV system and the computer management system, can be easily completed in a short time by simple insertion of the module of the present invention without complicated coding process. In case of a programming language running in a Windows environment, only the OLE insertion code provided by each language is input without exception, and if the DB processing related functions that have already been used are aligned according to the layout, the project is actually terminated.

Of course, an additional benefit of adopting such a development approach is that a vendor with DB administration responsibility and authority does not have to disclose important sales information, including the DB, to the inventor who has technology specialized only for image, Which makes it difficult to integrate systems.

In addition, in the post-maintenance period, it is possible to commercialize solutions with higher reliability and completeness in terms of minimizing opportunity costs to be devoted to R & D beyond their respective areas, to be.

The CCTV 300 is installed in a location where a computerized management system is managed to secure event information that occurs in video management, process management, document management, access control management, and logistics management, And has a function of shooting an event video.

The DVR 400 receives and records an event image photographed from the CCTV 300 and records and records an event from the terminal or server 200 including the image comparison management module It has a function to request a streaming image from the start point to the end point and to transmit the streaming image, and includes the DVR firmware. When receiving the serial number from the OCX module 210 in the terminal or the server 200 including the video comparison management module, the DVR 400 receives the serial number corresponding to the dynamic address management server 500 It queries the external IP and communication port of the device and transmits time synchronization information and streaming information to the destination address to which the response is received.

When the DVR 400 accesses the dynamic address management server 500 through the execution of the DVR firmware, the dynamic address management server 500 accesses the external IP and a communication port, and a function of transmitting / receiving external IP information through the communication port with the digital recording apparatus (DVR) 400.

Also, if the back-end operation between the OCX module and the DVR firmware is described, the OCX module can be written in the form of a DLL file and can be operated in both front-end and back-end. When the OCX module is inserted as an object in a program with a UI, the video streaming information that is transmitted is visually displayed on the front side of the program, and the front-end is executed so that the user can directly control and visually confirm the OCX module. Back-end refers to the fact that the interface is not exposed but is hidden behind the system.

Normally, since the server exists only for sending and receiving data with the client program, when the OCX module is executed on the server, it transmits the time synchronization information to the DVR in the back-end. , The OCX module should be executed in the back-end at the third server or the terminal, which is a standard of the time recorded in the DB.

When the event DB server, the administrator PC, and the DVR are located on the same network or all use public IP, it is possible to transmit / receive communication port information between the DVR and the dynamic address management server. There is no restriction on the communication of FIG. However, if the DVR is on a different network and is located under a DHCP server or router, the IP of the DVR becomes a private IP, so it can not be connected to the IP network from the external network.

Port Mapping, or Port Fowarding allows you to access the DVR from the outside via a router or a port assigned to a DHCP server. However, when the public IP assigned from the Internet service provider (ISP) to the router or the DHCP server is a dynamic IP, there occurs a problem that the external IP address is changed from time to time.

When the DVR accesses from time to time, the dynamic address management server dynamically records the external IP and the communication port where the DVR is located. In this case, the method of specifying the DVR in the OCX module and the dynamic address management server is the serial number assigned to the device.

When the serial number is called in the OCX module, the OCX module queries the dynamic address management server for the external IP and communication port of the corresponding device, and transmits the synchronization information and the streaming information to the response destination address.

The OCX module 210 in the terminal or the server 200 including the image comparison management module and the DVR firmware in the DVR 400 may be connected to the event DB server 100 or the image comparison management module The OCX module 210 transmits the information to the OCX module 210. The OCX module 210 transmits the information to the DVR firmware and synchronizes the time with the event database server 100 The streaming data is called from the DVR 400 and the OCX module 210 inserted into the existing management program is inserted into the existing management program. A stream image request and playback function for decoding and reproducing the received streaming data into a moving image and a stream image request and playback function for inputting an event point image and an end point image to the capture function of the OCX module 210, A stream image capturing function for converting an MP4 file format so as to be stored in the terminal or the server 200 and a port for securing an external IP and a port number of the DVR 400 when the DVR is located under a separate floating IP network, And performs mapping information receiving function.

In addition, by using an event - based image comparison management system, we can synchronize the time between the digitalized recording device (DVR) and the facility management computer system including the OCX module operated individually, and search, A process of sorting and cataloging recorded events in the CCTV, enlarging a specific channel, and storing an event image of a problem will be described as follows.

First, as a time synchronization process, there are two methods of time synchronization to accurately synchronize the generation time of the event DB with the on-scene recording time of a digital video recorder (DVR) The other method is to set the time of the server or the client computer that is the basis of the recording time of the event DB to be the same as that of the NTP server (Network Time Protocol Server) It is a method of loading and periodically pushing it into a digital recording device (DVR).

In the setting method of the time server, the OCX module provides a function of recording a time server in a firmware for a digitized recording device (DVR). When the address of the time server is inputted once in the function, the firmware basically requests time synchronization to the time server every 60 minutes.

Also, in the method of reading and synchronizing the computer time, when introduced into a solution that does not use a time server in terms of security policy, the database is converted into a database based on the computer time of a specific server or client. In this case, The OCX module has a function of forcibly setting the time value in the firmware for the digitized recording device (DVR), and the OCX module has a function for setting the time value to the location where the corresponding OCX module is installed in the back- If you enter the computer's time, synchronization will be forced.

Secondly, as an event retrieval process, an event-based image comparison management system is used. In FIG. 2, which is a screen of an actual captured image of a client program that has introduced an OCX module in a point- You can.

As shown in FIG. 2, the captured image is an actual captured image of a client program that has introduced an OCX module in a point-of-sale management solution in a retail retail plan plan.

In the three parts of the image, which are divided into the search condition part, the document detail part and the image display part, the search condition part and the document detail part utilize the interface which manages the event which occurs at the point of sale already in the existing point- And the image display unit embeds the OCX module.

The example of the image is to select about 10 problem events out of 5 to 600 events occurring during the entire business by designating a sales date, a payment means, a transaction type, and the like in a search condition part and requesting from the document DB. Information of the first input time (event occurrence point), settlement completion point (event end point) and counter number of the bar code scanner is recorded, and when the document is clicked on the document record, the camera number corresponding to the point- OCX module.

Third, the process of selecting and reproducing images at the event occurrence location is as shown in FIG. 3 in which the channel numbers of the cameras arranged by the counter numbers of the corresponding stores are simplified using an event-based image comparison management system And an event-based image comparison management system using the event-based image comparison management system and the screen shown in FIG. 4, which is an image captured before the document selection, in the front-end of the OCX module 5, which is an image captured after selection of a layout and a document to be rearranged when only the event image displayed on the front-end of the OCX module serving as an image display unit is selected and reproduced.

As shown in FIGS. 3 to 5, in the process of selecting and reproducing an image at an event occurrence position, the captured image is shown in FIG. 3. In FIG. 3, the channel numbers of the cameras arranged according to the counter numbers of the stores are simplified In FIGS. 4 and 5, when the physical channel arrangement and the event image displayed on the front-end of the image display unit, that is, the OCX module, are selected and reproduced, the layout to be rearranged is simplified and captured before and after selecting the slip. Which is the result of comparison between the images.

As described above, the following process is performed for switching from the 16-split screen to the 4-split screen and arranging the selected channels to play back. The first step is to check the counter number in the corresponding event column, Is a process of confirming the camera number given in advance by the counter number, and the third is a process of converting the screen division to 2x2 (for example) Form.SetScreenXY (2, 2); and fourth, 4 camera outputs, 8 camera outputs on channel 2 (example) camera [1] = 4; camera [2] = 8;). The OCX module allows you to freely convert the order of screen division and camera placement.

Fourth, as a process of enlarging a specific channel, when an event image is reproduced using an event-based image comparison management system, it can be seen from the screen of FIG. 6 which is an enlarged captured image after the selection of a document.

As shown in FIG. 6, the OCX module itself can be controlled in the front-end. If an enlarged image is to be displayed when an event image is being reproduced, the corresponding channel can be double-clicked. When the user double-clicks the channel in the upper left corner of the "Select Document After Selecting Document", the result shown in FIG. 6 is displayed. Double clicking the corresponding image again returns to the previous layout.

Fifth, the process of storing the image of the problem event. If the problem event is detected from the event image, it is necessary to remove the cause or to store the evidence separately for the problem resolution. The OCX module has an encoding function that uses the same parameters as the function of calling a streaming video. The video from the time of occurrence to the end of the event is compressed and stored by the MP4 type H.264 codec.

The above-described time synchronization process, the event search process, the process of selecting and reproducing the image of the event occurrence location, the process of enlarging the specific channel, and the process of storing the image of the problem event, System provides easy and fast means to integrate CCTV-event DB integration solution, prevents leakage of confidential information that may occur in heterogeneous system integration process, minimizes opportunity cost by concentrating competence in specialized areas And reliability can be secured.

Therefore, in the event-based image comparison management system of the present invention, from the viewpoint of dramatically shortening unnecessary search time, it is possible to detect changes in items such as monitoring of articles, people, money, facilities, and moving, loss, The time to occur is only a fraction of the time, and if it is possible to specify the characteristics of the problem situation even if it is comprehensive, for example, if it is possible to select only the management object or the event type, unnecessary long CCTV recording video need not be played back for the operating time. In other words, it is possible to respond more quickly and accurately than when CCTV solely manages to solve the problem.

Also, in terms of accurate and intuitive cause identification, there is no intuitive reasoning method as much as visually confirming the situation. If you want to solve the problem with only quantified statistics, you need to use complex and circumstantial estimates Indirectly, the cause can be identified through the family. And the problem that it is difficult to identify by computerized management system is that it provides easier and more reliable control by presenting a means to visually confirm the situation in the process.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is not.

As described above, the event-based image comparison management system of the present invention can be applied not only to a system for managing images but also to a process management system, a document management system, an access control management system, and a logistics management system There is a wide range of fields.
