Description

Technical Field

[0001] The present invention relates to a security surveillance camera system. More specifically, the present invention relates to a security surveillance camera system that uses a security surveillance camera equipped with an AI chip to perform secondary analysis and determination on a detected human image by means of AI.

Background Art

[0002] Security or surveillance cameras (hereinafter abbreviated as "security surveillance cameras") are used in various places. Among such security surveillance cameras, security surveillance cameras with AI functions are sometimes used. That is, a security surveillance camera with an AI function (hereinafter, the security surveillance camera with an AI function is abbreviated as "AI security surveillance camera") is equipped with an AI chip, which enables it to send notifications or the like of captured images or moving images in accordance with specific instructions (Patent Document 1). For example, an AI security surveillance camera installed outdoors detects a person, and a notification of the detection is sent to a smartphone or the like.

[0003] However, AI security surveillance cameras had problems. That is, the problem of false detection. For example, in the case of outdoor AI security surveillance cameras, animals, shadows, light reflections and the like were frequently falsely detected as people. These false positives, when reported, led to unnecessary dispatches, resulting in increased response costs and other problems. In addition, as the frequency of false detections increases, the possibility of delays in responding to truly highly urgent cases increases, which may undermine the very role of AI security surveillance cameras.

[Brief explanation of the drawing]

[Figure 2] A schematic diagram illustrating one aspect of a security surveillance camera system. [Figure 3] A schematic diagram illustrating one aspect of a security surveillance camera system. [Modes for carrying out the invention]

[0009] This document describes the security surveillance camera system of the present invention. The present invention relates to a security surveillance camera system comprising a trained AI chip for detecting people, a security surveillance camera equipped with communication functions, an image information analysis unit that analyzes and determines image information transmitted from the security surveillance camera using AI software, and an information transmission / reception unit that transmits the analysis and determination results of the image information to an information terminal. The security surveillance camera transmits only image information detected as a person by the AI ​​chip to the image information analysis unit, the image information analysis unit further analyzes the image information detected as a person using AI software to determine whether it is a person, and only if the analysis and determination in the image information analysis unit determines that a person has been detected does it transmit the analysis and determination result indicating that a person has been detected to the information terminal. The security surveillance camera system of the present invention can more accurately determine whether an image detected as a person by the security surveillance camera (hereinafter referred to as "person detection image") is a person by performing a secondary analysis using AI software in the information analysis unit. Furthermore, since the information determined to be a person through the secondary analysis (hereinafter referred to as "person determination information") can be received by a pre-configured information terminal, it is possible to reduce the frequency of being bothered by false detections.

[0010] In addition, the security surveillance camera system of the present invention has the following advantages and features. (1) Since security cameras are placed both outdoors and indoors, the communication environment is not always ideal depending on the location. With the configuration of the present invention, a security camera equipped with an AI chip does not need to continuously transmit images to the image information analysis unit, but only transmits human detection images to the image information analysis unit. This makes it possible to minimize the amount of communication from the security camera and reduce the load on the security camera. (2) In the present invention, the AI ​​software used is a commonly used image recognition type AI software (computer vision AI). In this case, the more images (or frames in the case of video) analyzed by the AI ​​software, the higher the usage fee for the AI ​​software. In the present invention, since only images detected as people by the security surveillance camera are transmitted, it is possible to minimize the number of images analyzed by the AI ​​software, which offers significant cost advantages. (3) Since the human detection images are subjected to secondary analysis by AI software, it is possible to determine whether or not a person is present more accurately than the results obtained by the security camera equipped with a trained AI chip alone. In addition, if the analysis results by the AI ​​software are incorrect, it is possible to improve accuracy by notifying the system and allowing it to learn from the error.

[0011] In this invention, the security surveillance camera is not particularly limited as long as it is equipped with an AI chip and communication functions, and various types of security surveillance cameras can be used. For the AI chip of the security surveillance camera, a trained AI chip for performing human detection may be used. In addition, the communication function of the security surveillance camera is not particularly limited as long as communication is possible, and various means can be adopted. Examples of such communication means include wired LAN, WIFI, and SIM cards, which can be used alone or in combination. As the security surveillance camera of the present invention, typically, commonly used security surveillance cameras such as dome cameras, box cameras, bullet cameras, PTZ cameras, and pinhole cameras can be used. These general-purpose security surveillance cameras are usually equipped with a communication function, and higher-grade models may be equipped with a human detection trained AI chip, so a security surveillance camera equipped with a human detection trained AI chip may be used.

[0012] In the present invention, the image information analysis unit plays a role of analyzing and determining whether an image detected as a person by the security surveillance camera (human detection image) is a person or not using AI software. The image information analysis unit is not particularly limited as long as it can perform the analysis and determination by such AI software, and may have various configurations and modes. Further, in the present invention, the information transceiving unit plays a role of receiving the human detection image from the security surveillance camera and transmitting notification information to the information terminal. The information transceiving unit is not particularly limited as long as it fulfills such a role, and may have various modes and configurations. Note that in the present invention, image information is defined to include not only image files but also moving image information such as mpeg that can be conceived as continuous images.

[0013] The image information analysis unit and the information transmitting / receiving unit may be configured as a cloud server. That is, the human-detected image received by the information transmitting / receiving unit is subjected to secondary analysis and determination as to whether it depicts a human by the AI software in the image information analysis unit. The image information analysis unit and the information transmitting / receiving unit are typically configured as a communication information device such as a personal computer, and the human-detected image is secondarily analyzed by the AI software installed on the communication information device. Although the human-detected image is analyzed and determined by the AI software, the actual analysis and determination is performed on the server of the AI software provider. Therefore, the communication information devices constituting the image information analysis unit and the information transmitting / receiving unit do not necessarily need to use high-performance devices, but preferably a desktop or laptop personal computer may be used, and a mobile terminal such as a tablet or a smartphone may be used instead. The AI software that can be used in the present invention is not particularly limited as long as it is AI software capable of analyzing and determining an image as a human, and various types of AI software can be used. Examples of such AI software include ChatGPT (registered trademark).

[0014] In the present invention, it is preferable that the analysis and determination result in the image information analysis unit further includes an image determined to depict a human, a web link to which the image is uploaded, or either or both of these. This enables final visual confirmation by the owner of the information terminal, and has the effect of making it possible to more accurately judge the authenticity of the human determination information and whether it is necessary to take action on the detected human. In the present invention, when the human determination information is a false detection, it is preferable that the information terminal can notify the information transmitting / receiving unit that the detection was a false detection. With such a configuration, the AI software can recognize and learn that the human determination information of the AI software was incorrect, which has the effect of making it possible to improve the accuracy of human determination. In the present invention, it is preferable that the operating time period of the security surveillance camera can be set from an information terminal. This suppresses unnecessary system operation, thereby preventing unnecessary analysis by AI software, and has the effect of reducing the operational burden and economic costs of the system itself.

[0015] The security surveillance camera of the present invention will be explained with reference to the drawings. Figure 1 shows one embodiment of the security surveillance camera of the present invention. The security surveillance camera system 1 of the present invention consists of a dome-type security surveillance camera 2 and a server 3. The server 3 includes an image information analysis unit 31 and an information transmission / reception unit 32 (not shown). The dome-shaped security camera is equipped with a human detection-trained AI chip and communication capabilities. Only when a person is detected, the image (human detection image) is transmitted to the server 3 via the information transmission / reception unit 32. The person detection image received by the information transmission / reception unit 32 is subjected to secondary analysis by AI software installed in the image information analysis unit 31 to determine whether it is truly a person. If it is determined to be a person, the person determination information is notified from the image information analysis unit 31 to the information terminal 4 via the information transmission / reception unit 32. Depending on the settings of the information terminal 4, either the image itself is sent or an image upload link is notified.
