Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the field of security technology, and in particular to a wake-up method, device, equipment and readable storage medium for a security camera system. Background Art
[0002] Most current security camera systems are equipped with internal rechargeable batteries to cope with abnormal power outages. In order to extend battery life, the system will enter low-power mode under certain circumstances. In this mode, the system relies on an external PIR (Pyroelectric / Passive InfraRed, passive infrared sensor) to detect the external environment. Once an abnormal temperature object moves tangentially, the camera system will be awakened and enter the video working state.
[0003] Among them, the working principle of PIR detection is that when an external abnormal temperature object (an object with a significant difference in temperature from the ambient temperature) moves tangentially, it will trigger the PIR interrupt signal to be transmitted to the MCU (Microcontroller Unit) to wake up the camera security system.
[0004] However, PIR is greatly affected by the ambient temperature. When the temperature of the target object is close to the ambient temperature, the sensitivity will drop significantly. PIR is more sensitive to radio frequency signals, and external WIFI\BT and other signals will cause strong interference to it, resulting in false triggering. PIR cannot distinguish whether the moving object is a person, other animals or other heat sources.
[0005] In view of this, how to provide a wake-up method, device, equipment and readable storage medium for a security camera system has become a problem that needs to be solved by those skilled in the art. Summary of the invention

[0041] The embodiments of the present invention provide a method, device, equipment and readable storage medium for waking up a security camera system, which has high sensitivity during use, is less affected by other signals, and can improve the efficiency and accuracy of waking up.
[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0043] Please refer to Figure 1 , Figure 1 A schematic flow chart of a method for waking up a security camera system provided by an embodiment of the present invention. The security camera system is provided with an image sensor, and the method comprises:
[0044] S110: When the security camera system enters the low power consumption mode, the image sensor is controlled to collect brightness information and infrared information;
[0045] It should be noted that, in the embodiment of the present invention, when waking up the security camera system, it can be achieved with the help of an image sensor. Specifically, when the security camera system enters a low power consumption mode, the image sensor can be controlled to collect brightness information and infrared information. Specifically, the image sensor can be controlled to enter an event detection and infrared detection mode. In this mode, the image sensor only performs brightness detection and infrared detection, that is, the image sensor collects brightness information and infrared information.
[0046] S120: Analyze the collected brightness information and infrared information, and control the security camera system to exit the low power consumption mode if it is determined that there is a moving target object.
[0047] Specifically, the brightness information and infrared information collected by the image sensor are analyzed to determine whether there is a moving target object, and when it is determined that there is a moving target object, the security camera system is controlled to exit the low power consumption mode.
[0048] When the security camera system is controlled to exit the low power consumption mode, the system power supply can be controlled to resume powering the security camera system, thereby waking up the security camera system to enable it to operate normally.
[0049] Furthermore, the process of analyzing the collected brightness information and infrared information in the above S120, and controlling the security camera system to exit the low power consumption mode when it is determined that there is a moving target object, may specifically include:
[0050] Based on the brightness information, it is determined whether there is a target object. If so, it is determined based on the infrared information whether the target object is moving. If so, the security camera system is controlled to exit the low power consumption mode.
[0051] It is understandable that in the embodiment of the present invention, the brightness information collected by the image sensor can be analyzed first. Specifically, in the actual application process, the image sensor collects brightness dot matrix information in the event detection and infrared detection modes, and specifically can collect multiple frames of brightness change dot matrix information. Specifically, by analyzing the brightness information, it can be determined whether there is a target object within the field of view, wherein the type of the target object can be pre-set, for example, the type of the target object can be a person or an animal, which can be determined according to actual needs. In the case where it is determined that there is a target object through the analysis of the brightness information, it is further determined whether the target object moves based on the infrared information, wherein the infrared information can also be multiple frames of infrared dot matrix information, and by analyzing the infrared information, it can be determined whether the target object moves.
[0052] Furthermore, the brightness information collected by the image sensor is brightness dot matrix information;
[0053] Then, the above process of judging whether a target object currently exists based on brightness information may specifically include:
[0054] Generate contour information based on brightness dot matrix information;
[0055] Matching the contour information with a pre-established biological linear model to obtain a matching result;
[0056] Identify whether the biological type corresponding to the matching result is the target object.
[0057] It is understandable that various biological linear models can be established in advance, each biological linear model corresponds to a biological type, the brightness dot matrix information collected by the image sensor is processed to generate contour information, and then the obtained contour information is matched with each biological linear model to obtain a biological linear model that matches it, that is, a matching result is obtained, and the matching result includes the biological linear model that matches it, and according to the biological type of the biological linear model, it is further determined whether it is the same as the type of the target object, that is, when the type of the target object is human, it is further determined whether the biological type of the biological linear model is human, and if so, it is determined that the target object currently exists.
[0058] Furthermore, the infrared information in the embodiment of the present invention is infrared dot matrix information;
[0059] Then, the above process of determining whether the target object is moving based on infrared information may specifically include:
[0060] Identify the motion state of the target object based on multi-frame infrared dot matrix information;
[0061] It is determined whether the target object is in motion based on the motion state.
[0062] It should be noted that when it is determined that there is a target object currently, the motion state corresponding to the target, such as whether it is moving or still, can be identified by analyzing multiple frames of infrared dot matrix information, and the amplitude and type of motion can also be identified, so as to determine whether the target object is moving. It can be seen that in the embodiment of the present invention, when it is determined that the security camera system enters the low power consumption mode, the image sensor is controlled to collect information and the collected information is analyzed. When it is determined that there is a moving target object currently, it indicates that security monitoring is required at this time, and the security camera system is controlled to exit the low power consumption mode; in the present invention, the information collected by the image sensor is analyzed to determine whether the security camera system needs to be awakened, which has high sensitivity and is less affected by other signals, and can improve the awakening efficiency and accuracy.
[0063] It should also be noted that in actual applications, the security camera system can be composed of an ISP (image signal process) module, an Audio module, a WIFI module, an RF (radio frequency) antenna, an MCU, a sensor system, a power system, an image sensor, a battery and a power adapter. The specific architecture is as follows: Figure 2 As shown. Among them, the ISP module is mainly used to process video signals and audio signals, and transmit audio and video information with the WIFI module through the data bus. The main function of the WIFI module is to combine the RF antenna module with the Internet terminal to send and receive audio and video signals. It can also upload the system status and issue terminal instructions. As the core module of the system, the MCU is used to control and monitor the system status, read and control the operation of the sensor system, and receive interrupts, data and other information transmitted by the sensor. The MCU controls the system power supply to enter different working modes by checking the working status of the monitoring system. The battery and power adapter power the entire system. The two can exist at the same time or separately.
[0064] Specifically, Figure 3 As shown, in the method in the embodiment of the present invention, the MCU is used to monitor the state of the security camera system. The MCU can be used to determine whether the security camera system enters the low power consumption mode, and when the security camera system enters the low power consumption mode, the image sensor is controlled to enter the event detection and infrared detection mode. In this mode, the image sensor only performs brightness detection and infrared detection, collects brightness information and infrared information, and analyzes and processes the brightness information to determine whether there is a target object. When it is determined that there is a target object, the infrared information is further analyzed to determine whether the target object moves. When it is determined that there is movement, the MCU is triggered to wake up. Specifically, the MCU can be used to control the start of the system power supply to provide normal power supply to the security camera system, specifically to restore the power supply to the ISP and other modules, and start the image sensor video monitoring, photo taking and other functions (that is, start the RGB acquisition function and the full pixel acquisition function), so as to wake up the system. During the wake-up process, it is not interfered by external radio frequency signals, and has high resolution and high recognition accuracy.
[0065] Based on the above embodiment, the embodiment of the present invention further provides a wake-up device for a security camera system. The security camera system is provided with an image sensor. Figure 4 , the device comprises:
[0066] The control module 11 is used to control the image sensor to collect brightness information and infrared information when the security camera system enters the low power consumption mode;
[0067] The exit module 12 is used to analyze the collected brightness information and infrared information, and control the security camera system to exit the low power consumption mode when it is determined that there is a moving target object.
[0068] Furthermore, the control module 11 is specifically used to control the image sensor to enter the event detection and infrared detection modes and collect brightness information and infrared information when the security camera system enters the low power consumption mode.
[0069] It should be noted that the wake-up device for the security camera system provided in the embodiment of the present invention has the same beneficial effects as the wake-up method for the security camera system mentioned above, and for the specific introduction to the wake-up method for the security camera system involved in the embodiment of the present invention, please refer to the above embodiment, and this application will not go into details here.
