Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the protection scope of the present invention.

According to an embodiment of the present invention, a police system based on a smart wearable device is provided.

As shown in FIG. 1, a police system based on a smart wearable device according to an embodiment of the present invention includes: a smart wearable device 10 and a control center 20. Wherein, the smart wearable device 10 includes an image collection device, and the image collection device can perform image collection according to actual needs, for example, collect images of surrounding people. The control center 20 includes a back-end server 22 that is communicatively connected to the smart wearable device 10. The background server 22 is used to match the image data sent by the image acquisition device with the target database, and when the image data matches the target database successfully, return a matching result to the smart wearable device 10.

The above technical solution of the present invention scans the image data through the image acquisition device of the smart wearable device 10 and returns the matching result after successful matching through the background server 22, so that the target person can be found in the crowd without being noticed by the target person It is convenient to assist police officers in patrol work, arrest and track fugitives, find and identify dangerous persons or key persons, improve the efficiency of solving cases, and protect public safety.

In addition, when the matching of the image data with the target database fails, the background server 22 is also used to return the matching failure result to the smart wearable device 10, and according to the matching failure result, the image acquisition device will continue to collect the image data.

In some embodiments, the smart wearable device 10 is a smart helmet. It should be understood that other types of smart wearable devices 10 may also be selected to collect image data according to actual applications. In addition, the background server 22 and the smart wearable device 10 can be communicatively connected through a network connection such as a 4G network or a Wifi network. In some embodiments, the image acquisition device may be a camera.

In one embodiment, the image acquisition device may include an image acquisition module and an image processing module communicatively connected to the image acquisition module. Among them, the image acquisition module is used to collect original image data, and the image processing module is used to identify the collected original image data, and when the original image data is recognized as a predetermined image, the original image data is used to match the target database Part of the image data is sent to the background server 22. After identifying the collected original image data through the image processing module, only part of the original image data identified as the predetermined image is sent to the background server 22 to match the target image database with the partial image data, which can further improve effectiveness.

Further, the predetermined image may be a face image, and part of the image data is a face image in the original image data. That is to say, the original image of the crowd is scanned by the image acquisition device, if the face image is recognized, the original image is acquired and the face image of the original image is intercepted, and the intercepted face image is transmitted to the background server 22.

As shown in FIG. 2, in one embodiment, the control center 20 further includes a push server 26 and a background terminal 24. The push server 26 is in communication connection with the smart wearable device 10, and the background terminal 24 is in communication connection with the push server 26. When the image data matches the target database successfully, the smart wearable device 10 transmits the collected live picture to the background terminal 24 of the control center 20 through the streaming server 26 to live broadcast the live picture. Therefore, by live broadcasting the live picture on the background terminal 24, it is convenient for the staff to reconfirm the live picture at the background terminal 24 and effectively direct the scene.

In one embodiment, the smart wearable device 10 may further include a display device, such as a translucent AR (enhanced display) lens of the smart wearable device 10. The display device is used to display the matching result. In addition, the smart wearable device 10 may also include a voice broadcast device, such as a headset. The voice broadcast device is used to broadcast the matching result. In this way, it is easier to assist the police officer to obtain the matching result returned by the background server 22.

In one embodiment, the control center 20 may further include a push module. When the image data matches the target database successfully, the push module is used to push information related to the matching result to the smart wearable device 10. For example, the relevant information may be wanted files, pictures, text, or a combination thereof. Therefore, on-site police officers can get more relevant information in time to further assist police officers in their work.

In one embodiment, the smart wearable device 10 may further include a communication module for performing voice communication with the background terminal 24 of the control center 20, thereby facilitating command and control of the scene.

In order to facilitate understanding of the present invention, the technical solution of the present invention will be specifically described below with reference to FIGS. 2 and 3. It should be noted that the smart wearable device is used as a smart helmet as an example for description, but this does not limit the present invention.

In step S302, the crowd is scanned through the invisible camera on the smart helmet. In step S304, it is determined whether a face image is scanned, and if no face image is scanned, it returns to step S302. If a face image is scanned, step S306 is performed to obtain a picture and capture an avatar image of the face. And in step S308, it is transmitted to the background server 22 through a network such as 4G or Wifi. In step S310, the background server 22 calls the intelligent search and recognition algorithm server according to the graph. In step S312, the algorithm server recognizes the feature of the picture and matches it with the face database, and returns the matching result. The background server 22 receives the picture matching result. If the matching result is successful, proceed to step S314. In step S314, the archive is called to query the basic information of the person corresponding to the picture and return the result to the smart helmet. Translucent AR lenses display the results and broadcast the results through invisible headphones. If the matching fails, a failure result is returned to the smart helmet, scanning and recognition are continued, and step S302 is executed.

In addition, when scanning to find the offense, the police system of the present invention can start live broadcasting, and pass the live scanned picture to the background terminal 24 of the control center 20 through the live streaming push method, so that the background terminal 24 of the control center 20 can watch To the live screen. The system can also use the smart helmet's calling card to make and receive calls to maintain communication with the control center 20, and the control center 20 can also push information such as wanted files, pictures, text, or a combination thereof to the smart helmet according to the situation.

The technical solution of the present invention can also be applied to other terminal devices, as well as to the fields of identifying people, animals, and regular items. For example: use a mobile phone or a terminal device that can load the system engine to take pictures or scan people to perform face recognition, and return information such as its name, age, position, and whether it is a dangerous person; taking pictures or scanning animals can identify the animal ’s Basic information such as name, type, habit, and degree of danger; basic information such as plant name, type, habit, use, and whether it is toxic can be identified by taking pictures or scanning plant leaves; and taking pictures and scanning objects such as chairs, mobile phones, and stones Identify.
