Description

Technical Field

[0001] The present invention relates to the technical field of information processing, and more specifically to a security monitoring information processing system. Background Art

[0002] Security monitoring is increasingly widely used in schools, factories, or enterprises and institutions. Through audio and video acquisition and transmission technology, security monitoring can collect static or dynamic images of the monitoring site and identify the sounds of the on-site environment, effectively enhancing the security of its application scenarios. Existing security monitoring systems usually have surveillance cameras in multiple directions, which can simultaneously monitor dynamic images from different perspectives in the on-site environment. By cooperating with Analog High Definition (AHD) technology, the clarity of the monitoring field of view of security monitoring can be effectively extended, thereby increasing the distance within the monitoring field of view.

[0003] However, the information processing system of existing security monitoring cannot adaptively call the AHD module according to the shooting angles of cameras at different positions on the security monitoring. For scenes close to the camera (within 10 meters), even without using the AHD module to process images, clear shooting effects can be obtained within the depth of field of the camera itself. Since the existing security monitoring information processing system uses the AHD module to perform high-definition processing on images during each image acquisition process, the computing power resources of the security monitoring information processing system are consumed relatively large. Especially when AHD modules are simultaneously called by cameras in multiple different directions, it is difficult to meet the requirements of long-distance image processing, resulting in serious overheating of the security monitoring housing and then causing video image jamming. Summary of the Invention

[0004] The purpose of the present invention is to provide a security monitoring information processing system to solve the problems mentioned above.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A security monitoring information processing system, including a central processing unit, a first video transmission module, a second video transmission module, a camera group, an angle sensor group, and a comparison module. The central processing unit is used to execute program instructions and perform arithmetic and logical operations on the received data using an algorithm program. The first video transmission module is used to output a standard video image signal, and the first video transmission module is connected to the first pin of the central processing unit. The second video transmission module is used to output a high-definition video image signal, and the second video transmission module is connected to the second pin of the central processing unit.

[0007] The camera group is used to collect video images of the monitoring site and send the collected video image information to the central processing unit in the form of data. The camera group is connected to the third pin of the central processing unit.

[0008] The angle sensor group is used to collect the shooting angle information between the camera group and the horizontal direction, and send the shooting angle information to the central processor. The angle sensor group is connected to the fourth pin of the central processor.

[0009] The comparison module is used to compare the received shooting angle information with a preset angle value to generate a comparison result signal, and send the comparison result to the central processor. The central processor calls the first video transmission module or the second video transmission module to output a video image signal according to the comparison result signal. The comparison module is connected to the fifth pin of the central processor.

[0010] As a further solution of the present invention: The algorithm program is stored on the algorithm module. The algorithm module is connected to the input pin of the central processor. The algorithm module includes a target detection algorithm unit, a target tracking algorithm unit, a face recognition algorithm unit, a behavior recognition algorithm unit, and a pose estimation algorithm unit.

[0011] The target detection algorithm unit is used to automatically detect and locate target objects in the surveillance video, such as people, vehicles, or animals. The algorithms included in the target detection algorithm unit are YOLO algorithm and / or SSD algorithm and / or Faster R-CNN algorithm. The target detection algorithm unit is based on the convolutional neural network CNN framework, with the advantages of high accuracy and real-time performance.

[0012] The target tracking algorithm unit is used to continuously track the target after it is detected and obtain its motion trajectory. The algorithms included in the target tracking algorithm unit are SORT algorithm and / or DeepSort algorithm. The target tracking algorithm unit uses Kalman filtering or deep learning to achieve stable tracking of the target.

[0013] The face recognition algorithm unit realizes the identification of individual identities by extracting and comparing the facial features in the collected video. The algorithms included in the face recognition algorithm unit are FaceNet algorithm, Deep ID algorithm, and ArcFace algorithm.

[0014] The behavior recognition algorithm unit is used to analyze the motion trajectory and action feature information of the target, so as to identify the actions performed by the target, such as running, falling, wandering, fighting, etc. The algorithms included in the behavior recognition algorithm unit are I 3D algorithm and / or C3D algorithm and / or LSTM algorithm. The behavior recognition algorithm unit can realize the intelligent recognition and classification of human behaviors.

[0015] The pose estimation algorithm unit is used to estimate the pose of the human body or object, that is, the joint point position, which is beneficial to improving the simulation accuracy of people and animals.

[0016] As a further solution of the present invention: The first video transmission module is a CVBS module, and the CVBS module outputs a standard-definition composite synchronous video broadcast signal through an analog waveform.

[0017] As a further solution of the present invention: The second video transmission module is an AHD module. The AHD module adopts Y / C signal separation technology, analog filtering technology, and noise reduction technology. Among them, the Y / C signal separation technology can separate the luminance signal and the chrominance signal to realize the transmission of high-definition video signals on coaxial cables, so that the long-distance video transmission clarity of the second video transmission module is higher than that of the first video transmission module.

[0018] As a further solution of the present invention: The camera group includes several rotating cameras. The several rotating cameras can adjust the shooting angle in the vertical direction. Specifically, the rotating camera relies on a built-in servo motor at one end to adjust the angle between it and the horizontal direction. When the angle between the rotating camera and the horizontal direction ranges from 0° to 30°, the angle sensor of the rotating camera corresponding to the action in the angle sensor group collects the angle data between the rotating camera and the horizontal direction and sends the angle data to the signal input end of the central processor. The signal output end of the central processor sends the angle data to the comparison module. The comparison module sends a corresponding comparison result signal to the central processor according to the angle range where the angle data is located. The central processor calls the first video transmission module or the second video transmission module to transmit the video image to the display terminal according to the comparison result signal. By judging the shooting distance according to the angle between the rotating camera and the horizontal direction and judging the video clarity according to the shooting distance, it is possible to call the adapted first video transmission module 2 or second video transmission module 3 to transmit the video image, which is beneficial to saving the video storage resources of the central processor 1;

[0019] Among them, when the angle between the shooting angle of the rotating camera and the horizontal direction is in the range of [0° - 45°), the comparison module sends a first comparison result signal to the central processor. When the central processor receives the first comparison result signal, it calls the second video transmission module. When the angle between the shooting angle of the rotating camera and the horizontal direction is in the range of [45° - 90°), the comparison module sends a second comparison result signal to the central processor. When the central processor receives the second comparison result signal, it calls the first video transmission module.

[0020] As a further solution of the present invention: It further includes a WI FI module. The WI FI module is used for the first video transmission module and / or the second video transmission module to send video images to the display terminal. The WI FI module is connected to the sixth pin of the central processor. By using the WI FI module as a wireless communication module for video image transmission, it is possible to wirelessly transmit video image information, which is convenient for improving the convenience of video image transmission.

[0022] As a further solution of the present invention: it further includes a sound sensor, which is used to collect the sound information at the shooting site of the camera group and send the collected sound signal to the central processing unit. The sound sensor is connected to the eighth pin of the central processing unit. The sound collected by the sound sensor and the video image information collected by the camera group are in a synchronous state, which can ensure that the sound collected by the sound sensor is synchronized with the picture, facilitating security personnel to understand the shooting content of the camera group.

[0023] As a further solution of the present invention: it further includes a temperature sensor, which is used to collect the temperature information of the central processing unit and send the temperature information data to the central processing unit. The central processing unit compares the received temperature information data with a preset temperature alarm value threshold. When the received temperature information data exceeds the temperature alarm value threshold, the central processing unit sends an alarm drive signal. The temperature sensor is connected to the ninth pin of the central processing unit. By monitoring the temperature value of the central processing unit in real time, it is convenient for maintenance personnel to master the working state of the central alarm and avoid high-temperature short-circuit accidents from affecting the security monitoring effect.

[0024] As a further solution of the present invention: it further includes an alarm module, which is used to receive the alarm drive signal sent by the central processing unit and issue an alarm signal. The alarm module is connected to the tenth pin of the central processing unit. By setting the alarm module, the operating state of the central processing unit can be alarmed. The alarm module is an audible and visual alarm, which can attract the attention of maintenance personnel by alarm whistling or alarm light flashing, so as to repair and adjust the central processing unit as soon as possible.

[0025] As a further solution of the present invention: it further includes a storage module, which is used to store the video image data collected by the camera group and the sound information data collected by the sound sensor.
