Description

Technical Field

[0001] The present invention relates to the field of identification technology, and in particular to a terminal information collection device and method for a network point. Background Art

[0002] Bank branches usually store a large amount of cash, including the reserve funds required for daily operations and cash deposited by customers. They also keep customers' valuables, such as gold, jewelry, and important documents (such as wills, property certificates, etc.). These cash and valuables are important assets for bank operations and are also targets coveted by criminals. For example, in some bank robbery cases, the main purpose of criminals is to rob cash.

[0003] In order to improve the security of bank branches, security measures are usually installed when bank branches are established, such as equipping banks with monitoring systems. A large number of surveillance cameras are installed inside and around the bank, covering business halls, self-service areas, safes, stairwells, corridors and other areas.

[0004] With the development of Internet of Things technology and identification technology, the functions of security systems with identification functions, including cameras, have gradually become richer. For example, the information extracted by the camera can be analyzed to identify the information of the person being photographed, which provides great convenience for pursuing fugitives and improving security. There are many types of systems with recognition functions. For example, a Chinese patent with patent publication number CN104951773A discloses a real-time face recognition monitoring system, which includes a monitoring system and a face recognition system. The video signal collected by the monitoring system is compressed locally and input into the face recognition system through the network; the face recognition system mainly includes a face capture engine, an interference restoration engine, a face modeling engine, a face comparison engine, and a database; the computer is connected to the monitoring system through a switch; the photo library stores the original comparison photos; the face capture engine collects and obtains 2D portraits containing facial biometrics in video or image information through a video input device; the interference restoration engine corrects and restores the captured 2D portraits; the face modeling engine performs 3D expansion and 3D modeling on the collected 2D portraits that meet the modeling conditions to generate 3D feature values; the face comparison engine compares the 3D feature values ​​generated by the acquired 2D portraits with the 3D feature values ​​generated by the photos in the photo library to obtain the comparison results. For example, in a human body recognition system and human body recognition method disclosed in a Chinese patent with patent publication number CN109465819A, the robot control device registers the facial data acquired by the robot and the gait data acquired by the surveillance camera in correspondence with the identifier of the human body based on the position information of the robot and the position information of the surveillance camera that can capture the robot. Then, the robot control device uniquely determines the user (user identification information) by using the facial data of the person acquired by the robot or the gait data of the person acquired by the surveillance camera, or using the data of both.

[0005] By using the recognition system provided by the above patent, the acquired image can be identified, and then the specific information of the person can be determined. However, the recognition system provided by the above patent has certain defects, because if you want to determine the specific information of the person, you need to store a large amount of personal information of dangerous elements (i.e., those with criminal records) or fugitives in advance, and compare with these pre-stored personal information to determine whether the person is socially dangerous. Therefore, the above recognition system is not convenient for taking effective measures in a timely and rapid manner against people who first perform socially harmful behaviors, because the recognition system cannot identify people for whom no information is retained. From the many social intentional injury incidents that have occurred, it can be seen that the perpetrators all use controlled instruments such as knives to commit crimes. If the recognition system can identify controlled instruments such as knives and promptly remind security personnel, it will improve the security personnel's response efficiency to social intentional injury incidents. In addition, even if it is detected that the person has a criminal record, it is not convenient to monitor the dangerous elements in real time. Summary of the invention

[0006] The purpose of the present invention is to provide a terminal information collection device and method for bank branches, aiming to improve the problem that the personnel information identification system can only timely identify persons who are socially dangerous, but is not conducive to timely reminding bank branch staff to take collection measures for dangerous persons who disrupt social order and endanger people's lives for the first time.

[0021] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0022] like Fig.13 , Fig.14 As shown, a terminal information collection device for network points includes an information collection device, an image recognition system and an alarm system. The information collection device can be a camera or other device with monitoring function. The image recognition system includes image processing, feature extraction and image recognition. The image processing includes a noise filtering module and an image converter. The noise filtering module mainly filters the image to eliminate noise. The image converter performs pattern conversion. The alarm system can use an alarm sensor to realize an alarm. The specific recognition method includes the following steps: Step 1: The information collection device works to patrol the area it covers and take full-body images of people in the area. The collected image information is sent to the image recognition system through the Internet of Things information carrier (specifically, the Internet, traditional telecommunications network and other information carriers). As can be seen from the above, the image extractor is electrically connected to the image recognition system through the Internet or traditional telecommunications network. After taking the image, the image information can be transmitted to the image recognition system, which processes the image information and makes corresponding judgments.

[0023] Step 2: After the image recognition system receives the image information, it first filters the image noise through the noise filtering module, and then transforms the image through the image converter. After the above processing, it extracts features from the processed image and normalizes the image.

[0024] Step 3: Extract parameters from the pattern and identify the pattern with reference to the personal database and knife database. The personal database stores a large amount of information about people with criminal records, and the knife database includes information about different types of controlled knives. By referring to the database, identify whether the person in the image is socially dangerous. If it is identified as a dangerous person, or if it is identified that the person is carrying a controlled knife, the alarm system sends an alarm to the control center and security personnel so that the security personnel can take timely measures.

[0025] Step 4: If there is no social danger or the knife is not detected, stop the identification task.

[0026] The above-mentioned recognition method is carried out on the basis of some hardware, such as a high-performance CPU or GPU capable of running visual algorithms, a storage device capable of storing images and video data, as well as model parameters and results, an image acquisition device for acquiring original image data, and a network for interconnecting all ordinary physical objects that can be independently addressed, that is, an Internet of Things based on information carriers such as the Internet and traditional telecommunications networks. Example 2

[0027] like Figure 1-Figure 12As shown, based on Example 1, the image acquisition device (ie, information acquisition device) used for the recognition method will be described in detail below. The image acquisition device includes a hemispherical transparent shell 1, a top seat 2, a support plate 6, a first camera 3 and a second camera 5.

The technologies for controlling the operation of each device and providing electrical energy for the operation of each device are all existing technologies and will not be described in detail here. An external threaded tube 25 is fixedly arranged at the lower end of the top seat 2, and a first internal threaded tube 11 is arranged on the top of the hemispherical transparent shell 1. The first internal threaded tube 11 is threadedly sleeved on the external threaded tube 25. The support plate 6, the first camera 3 and the second camera 5 are all arranged in the space formed by the top seat 2 and the hemispherical transparent shell 1. The support plate 6 is arranged on the inner side of the top seat 2. The first camera 3 and the second camera 5 are jointly arranged below the support plate 6, and the first camera 3 is arranged in the middle of the support plate 6. The second camera 5 that can revolve around the central axis of the support plate 6 is arranged at the edge. The first camera 3 and the second camera 5 can both collect images of people in the area they cover, and receive instructions from the processor to adjust their own tilt angles. In addition, the second camera 5 can adjust its position relative to the first camera 3 under the instructions of the processor, which facilitates the tracking of dangerous elements or elements carrying knives, so as to place dangerous elements or elements carrying knives under their monitoring range. In order to achieve full-process monitoring, it is necessary to set up multiple image acquisition devices, and use the linkage of multiple image acquisition devices to achieve full-process monitoring, providing support for security personnel to collect rich European images in a timely manner.

[0028] In order to adjust the tilt angle of the first camera 3 and the second camera 5, a first bracket and a first through-type lead screw stepper motor 31 are arranged above the first camera 3.

Under the action of multiple supporting wheels 71, the annular plate 7 is stably and movably arranged below the support plate 6, and at the same time, it is convenient to disassemble and assemble the annular plate 7 according to needs. In addition, under the operation of the first motor 72, the driving gear can be controlled to rotate, and then the annular plate 7 can be controlled to rotate around the central axis. Because the second bracket is arranged below the edge of the annular plate 7, the second camera 5 is driven to revolve, which is convenient for tracking dangerous personnel or people carrying knives.

[0030] After adjusting the position of the second camera 5, in order to adapt it to tracking a certain person, it is also necessary to adjust the direction of the second camera 5. A convex tube 55 is fixedly provided above the second bracket.

Both ends of the support plate 6 are arranged as step grooves 63. The protruding plates 24 are connected by bolts and arranged in the step grooves 63. In addition, a wire hole 62 is arranged on the support plate 6. The wire hole 62 is arranged near the center of the top seat 2 to facilitate the camera cable to pass through and connect to the processor. A certain length of the cable used to connect the second camera 5 is reserved to facilitate the forward and reverse revolution of the second camera 5 around the axis, thereby avoiding damage to the cable due to the revolution of the camera.
