Due to the portability of the mobile phone and the features of widespread use, the method and terminal provided by the present invention can provide an easy-to-use security solution for the user. The following is a detailed description of the embodiments.

2 is a schematic flow chart of a home security method according to an embodiment of the present invention. The method shown in FIG. 2 is applied to a terminal provided with a photoelectric proximity sensor and a camera. The terminal can be a mobile terminal. Mobile terminals include, but are not limited to, mobile devices, personal digital assistants (PDAs), tablets, portable devices (eg, portable computers, pocket computers, or handheld computers) with mobile devices having image capture capabilities. The embodiment of the present invention does not limit the form of the terminal. The method shown in Figure 2 includes:

S110, obtaining a first object distance from the photoelectric proximity sensor.

Specifically, the terminal may be pre-configured with a normal mode and a security mode. When the user needs to use the security function of the terminal, the security mode setting information is input to the terminal to enable the security function to be turned on, or to be set after being turned on. The manner of inputting the security mode setting information is, for example, the user turns on the preset security function button, or the user activates the security function by making a preset gesture action, or the user shakes the terminal at a preset frequency, wherein the preset The gesture action can be to slide on the screen with a predetermined trajectory. The terminal adjusts the transmit power of the photoelectric proximity sensor to a preset security power according to the security mode setting information input by the user, wherein when the photoelectric proximity sensor is set to the preset security power, the maximum sensing distance of the photoelectric proximity sensor is greater than or equal to 2 Meter. Obviously, the transmit power of the photo proximity sensor in the security mode is higher compared to the normal mode.

Wherein, the photoelectric proximity sensor obtains the first object distance between the detected object and the terminal according to the time difference of the transmission and reception of the electrical signal. In this embodiment, the photoelectric proximity sensor comprises a light emitter, a light receiver and a detection circuit, and the detection circuit is connected to the light receiver. The light emitter can be a Light Emitting Diode (LED) or a semiconductor laser tube. The light receiver may be a phototransistor, and the receiving band of the light receiver overlaps with the emission band of the light emitter. The photoelectric proximity sensor in this embodiment will be described by taking an optical transmitter as an LED and a photoreceiver as a phototransistor as an example. In the photoelectric proximity sensor, the beam axis of the LED and the axis of the phototransistor are in a plane at a certain angle, and the two axes intersect at a point in front of the photoelectric proximity sensor. When the object reaches the intersection position or approaches the photoelectric proximity sensor through the intersection point, the light emitted by the LED is reflected by the surface of the object, the reflected light is received by the phototransistor, and the detection circuit connected to the phototransistor generates an electrical signal. when When the object is far away from the intersection, the reflection area is not within the angle of view of the phototransistor, and the detection circuit has no output. Further, the driving current of the light emitting diode may be an alternating current of a certain frequency, so that the receiving circuit obtains an alternating signal of the same frequency. If the received signal is filtered, only signals of the same frequency are allowed to pass, which can effectively prevent interference of other stray light. In this embodiment, the light emitted by the photoelectric proximity sensor may be infrared light, and the receiver is correspondingly an infrared receiver, which can reduce light interference in the surrounding environment.

S120. When it is determined that an object approaches the terminal according to the first object distance, obtain an image to be recognized corresponding to the object from the camera.

Wherein, the image to be recognized is an image taken toward the sensing direction of the photoelectric proximity sensor.

Specifically, when it is determined that an object is close to the terminal, it may be that someone is approaching, or the door may be blown by the wind, the paper is falling, etc., and if it is directly determined to be an intrusion, it will cause a false alarm and cause interference to the user. . In this embodiment, when an object is determined to be close to the terminal, the camera detects the object detected in front, and obtains the image to be recognized, so that the object causing the movement can be further analyzed to reduce the false alarm rate. Wherein, according to the first object distance, an implementation manner of the object approaching the terminal is determined, and the first object distance obtained in real time may be compared with a fixed setting threshold value, and less than the threshold value indicates that an object is close to the object; An object distance is compared with each other, and if the first object distance obtained later is smaller than the first object distance obtained first, it also indicates that an object is close.

S130. Determine whether the captured face image matches the preset face image when the captured face image is obtained according to the image to be recognized. If yes, execute S140, if no, execute S150.

Specifically, after obtaining the image to be identified, the terminal first determines whether the recognized image includes a face, and if the image to be recognized includes a face, performing image processing to obtain a captured face image; if the image to be recognized does not include a face, according to When the image to be recognized cannot obtain the captured face image, one of the following two implementation manners may be performed: In an implementation manner, if it is considered that no one has entered, the process returns to S120 to continue monitoring whether an object is approaching. In another implementation manner, it is considered that an image of a human face or a similar human face may not be captured, and the short video to be processed is acquired from the camera. The short video to be processed may be a short-lived video that is quickly captured, such as a short video to be processed of 10 seconds. Then, it is determined whether the short video to be processed includes a video face image, whether the short video to be processed includes the retrieval and recognition of the face, and if the short video to be processed includes the video face image, indicating that at least one frame image of the short video to be processed is captured. When the face image is reached, the video face image is obtained from the short video to be processed, and the video face image is determined as the captured face image. The video face image is a frame image containing a face image in a short video to be processed. Further, the video face image may be a frame image containing the most complete face image in the short video to be processed. After obtaining the video face image, the video face image is determined as the captured face image, and it is determined whether the captured face image matches the preset face image. If the face image cannot be retrieved in the short video to be processed, it indicates If there is no entry, return to S120 and continue to monitor if there is an object approaching.

The user can pre-store the face image in the terminal, and usually can store the facial image of the family member who is often resident, and can also add the face image of the relatives and friends during the stay of the relatives and friends. When the image of the face is obtained, it indicates that someone enters, and by further determining whether the captured face image matches the preset face image, it can be determined whether the incoming person is a preset relative or friend.

S140, does not process and continues to execute S110.

If the photographed face image matches the preset face image, the entered relatives and friends are entered, and it cannot be considered that the intrusion occurs and no processing is performed.

S150, an intrusion alarm is performed.

If the captured face image does not match the preset face image, then the entry is not the preset relatives and friends, but the stranger invades, and the terminal immediately performs an intrusion alarm. The manner of performing the intrusion alarm may specifically be one or a combination of the following.

One way to invade an alarm is to play a preset alarm tone. For example, the user pre-records voice or music as alarm audio, and plays pre-recorded voice or music when performing an intrusion alarm. In the case of nighttime intrusion, by playing the alarm audio in the early stage of the invasion, it can serve the purpose of scaring off criminals and improving the security effect.

Another way to invade an alarm is to make a call with a preset alarm number. The preset alarm call can be the phone number of other family members, guardians, or the phone number of the alarm center, for example, 110. If the elderly or children in the family are alone at home, it is safer to notify the guardian or the alarm center in time than to notify the user at home to defend against the intruder.

In this embodiment, a first object distance is first obtained from the photoelectric proximity sensor; and when an object is determined to be close to the terminal according to the first object distance, an image to be recognized corresponding to the object is obtained from the camera, The image to be recognized is an image taken toward the sensing direction of the photoelectric proximity sensor; when it is determined that an object approaches the terminal, the camera detects the object detected in front, and obtains the image to be recognized, which can further perform the moving object. Analysis, reducing the false positive rate; then, when obtaining the captured face image according to the image to be identified, determining whether the captured face image matches the preset face image, and if not, indicating that the stranger is entering, proceeding Intrusion alarms improve the reliability of home security.

In the embodiment shown in FIG. 2, in addition to performing an intrusion warning, there may be a method step of providing a surveillance video to the police when the captured face image does not match the preset face image. A method of providing a monitoring video to the police when the photographing face image does not match the preset face image will be described below with reference to FIG.

FIG. 3 is a schematic flow chart of another home security method according to an embodiment of the present invention. The method shown in Figure 3 includes:

S210: continuously obtain monitoring video from the camera, and store the continuously acquired monitoring video locally.

Specifically, when the photographing face image does not match the preset face image, it indicates that a stranger enters, and the terminal immediately obtains the monitoring video from the camera. The start time of the surveillance video is the moment when it is determined that the captured face image does not match the preset face image. During the process of shooting the surveillance video, the terminal may also not make any prompts on the screen or the signal light to prevent the invading criminals from discovering that the surveillance video is being recorded through the special display of the terminal. The continuous acquisition operation of the monitoring video may be ended when the user inputs the stop information, or may be forced until the terminal is powered off automatically. The user input stop information may be the gesture operation information of the user, or the user may input the preset voice information to the terminal, or the user may shake the terminal by using the preset comment.

S220. Send the access key of the terminal and the image to be recognized to the preset alarm server.

The alarm server may be a server of the police or a server of the security service provider. This embodiment is described by taking the alarm server as a police server as an example. The terminal sends the image to be identified to the alarm server, which can be used as judicial evidence for subsequent intrusion alarms. On the other hand, it can be used as a preliminary judgment basis for the police to identify whether the terminal actually invades the behavior, and reduce the false alarm rate.

S230: When receiving the video acquisition request sent by the alarm server, determine whether the video acquisition request includes the access key, and if yes, execute S240; if no, execute S250.

After receiving the access key and the image to be identified, the alarm server manually determines the image to be recognized. If it is initially determined that the intrusion is possible, the terminal sends a video acquisition request including the access key to the terminal, so that the terminal will The continuously acquired surveillance video is transmitted to the alarm server.

S240: Send the monitoring video stored locally to the alarm server.

Specifically, when the access key in the video acquisition request is an access key sent by the terminal, indicating that the requesting party is legal, the locally stored monitoring video is sent to the alarm server. The terminal still obtains the monitoring video continuously, so after the local stored monitoring video is transmitted, the terminal will continue to transmit the new monitoring video obtained from the camera to the alarm server until the alarm server sends an instruction to terminate the transmission. signal.

In order to reduce the possibility of false alarms and avoid police errors, the terminal provides surveillance video to the police. The police can see and hear the alarm around the terminal in the surveillance video. If you see or hear the obvious burglary or burglary information. , you can immediately get out of the police, if you do not see or hear the obvious burglary or burglary information, you can also call the terminal to ask about the situation, to avoid the waste of police force caused by false alarms. The surveillance video can also be used as a judicial evidence for subsequent intrusion alarms and contains more information than the picture.

S250, reject the request.

If the access key is incorrect, or the access key is not included in the video acquisition request, it indicates that the requesting party is illegal. It may be that other users who are not police want to obtain surveillance video in the terminal, and the terminal rejects the request. Specifically, the manner of rejecting the request may be to feed back the rejection information to the alarm server, or may not feedback any information.

In this embodiment, when the photographing face image does not match the preset face image, the monitoring video is obtained from the camera, and the image to be recognized and the monitoring video are sent to the alarm server. This embodiment provides images and videos for the police to initially determine whether an intrusion has occurred and reduce the false alarm rate.

Based on the above-described embodiments of Figs. 2 and 3, the implementation of the first object distance from the photoelectric proximity sensor will be described in detail below.

In a specific implementation process, the object distance obtained from the photoelectric proximity sensor at the initialization time is determined as the second object distance, and the object distance obtained from the photoelectric proximity sensor after the initialization time is determined as the first object distance. The initialization time may be that the user turns on the security mode, and the image acquired from the camera is still after. For example, the user places the terminal on the bracket, and the terminal starts timing after the door is closed, and the pictures captured within 10 minutes are all still pictures, then the initialization time is reached at the 11th minute to obtain the second object distance. After the 11th minute, the first object distance is acquired.

Correspondingly, when determining whether an object is close to the terminal, the first object distance and the second object distance can be compared, and based on the comparison result, it is determined whether an object is close to the terminal.

Specifically, after obtaining the first object distance, it is first determined whether the first object distance is smaller than the second object distance; if so, it is determined that an object is close to the terminal, and if not, it is determined that no object is close to the terminal. In this embodiment, the method for determining that an object is close to the terminal is determined according to the current environment, and the second object distance and the first object distance obtained in different environments are different. This embodiment improves the flexibility of the terminal for security defense, and is applicable. A variety of application scenarios.

On the basis of the foregoing embodiment, in order to reduce the complexity of the calculation and reduce the calculation amount of the terminal, a method of calculating the period may be introduced before the determination that the first object distance is smaller than the second object distance. Taking a preset time period as a calculation period, first determining whether a plurality of first object distances obtained in the preset time period are consistent; if not, acquiring a minimum first object distance from the plurality of first object distances. Correspondingly, determining whether the first object distance is smaller than the second object distance can be simplified as: determining whether the minimum first object distance is smaller than the second object distance. In this embodiment, it is not necessary to determine whether the first object distance obtained each time is smaller than the second object distance, but after the preset time period ends, select the smallest of all the first object distances obtained in the preset time period. The first object distance is compared with the second object distance, so the real-time calculation is converted into a period calculation with a preset time period as a cycle, which reduces the computational burden.
