Detailed Description
In order to make those skilled in the art better understand the technical solution of the present application, the method for monitoring a fall, the terminal and the storage device provided by the present invention are further described in detail below with reference to the accompanying drawings and the detailed description.
With the increase of age, the functions of the body of the old also gradually deteriorate, and fall prevention becomes an important subject of all countries in the world. At present, some anti-falling products exist in the market, and after a user is detected to fall down, a rescue call is sent to a guardian. However, due to some special situations, the guardian may not be able to receive the rescue call in time, and in such a situation, the elderly may miss the best rescue opportunity. In order to enable the old people to be rescued in time after falling down, the application provides a falling monitoring method.
Referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of a fall monitoring method according to the present application, in which the fall monitoring method of the present embodiment includes:
s11: a monitoring mode is entered.
The terminal enters a monitoring mode and starts to detect whether the user obtains rescue. In this embodiment, after the terminal detects that the user falls down and sends rescue information, the terminal automatically enters a monitoring mode. In another embodiment, the terminal enters the monitoring mode after receiving the operation instruction of the user. For example, after the user falls down, the terminal can be triggered to enter the monitoring mode through manual operation, and the terminal can be triggered to enter the monitoring mode through modes such as voice passwords and the like. In other embodiments, the terminal automatically enters the monitoring mode upon detecting a fall of the user.
After the terminal enters the monitoring mode, a camera of the terminal can be started to shoot, or a microphone of the terminal is started to receive external voice input. Optionally, after the terminal enters the monitoring mode, positioning software can be started to position the terminal, and a temperature sensor or a pulse sensor of the terminal can be started to perform health detection on the user. Preferably, after entering the monitoring mode, in order to be able to record the health status of the user in real time, the terminal acquires at least one of the pulse, the heart rate and the body temperature of the user.
S12: and acquiring a first picture through a camera of the terminal.
And when the terminal enters a monitoring mode, automatically opening the camera to acquire a first picture. In a specific embodiment, after the terminal enters the monitoring mode, the first picture is acquired through the camera immediately, so as to obtain the initial environment of the user after falling. In other alternative embodiments, the first picture may be obtained by the camera of the terminal after the terminal enters the monitoring mode for a certain time, for example, the first picture may be obtained by the camera after 5s, 10s or 1 minute after the terminal enters the monitoring mode.
When the terminal is provided with a plurality of cameras, all the cameras can be opened to shoot, and a picture with the highest definition is selected from the shot pictures to serve as a first picture.
The first picture can also be selected by making the cameras of the terminal take a fixed number of pictures, for example, each camera takes 3 or 5 pictures, and then selecting the picture with the highest definition from the taken pictures.
S13: and acquiring a second picture by a camera of the terminal at preset intervals.
After the first picture is acquired, the initial environment where the user falls down can be acquired through the first picture. In order to confirm whether the user moves after falling down, after the first picture is acquired, a second picture is acquired at a preset time interval through a camera of the terminal, so that the environment of the user after the preset time interval is obtained. The preset time of the interval may be set by the user according to actual conditions, for example, the preset time may be set to 5 minutes, 10 minutes, 15 minutes, and the like.
After the preset time, the terminal acquires the second picture through the camera, and when the terminal comprises a plurality of cameras, the cameras acquiring the first picture and the second picture are the same. Namely, after a preset time interval, a camera for acquiring the first picture is opened, and the second picture is acquired. Optionally, a picture may be obtained by the camera, and the picture is taken as a second picture; the method can also acquire a predetermined number of pictures, such as 3 pictures, 5 pictures and the like, and then select the picture with the highest definition as the second picture from the acquired pictures.
S14: and comparing the first picture with the second picture, and judging whether the terminal moves according to the comparison result.
After the first picture and the second picture are obtained, whether the terminal moves or not can be judged by comparing the first picture with the second picture. In one embodiment, after the first picture and the second picture are acquired, whether the first picture and the second picture are the same or not can be judged, and when the first picture and the second picture are the same, the terminal is considered not to be moved, and the user is in a state of not being rescued. When the first picture and the second picture are not identical, the terminal can be considered to be moved, and the user may be rescued at this time.
In another embodiment, the similarity between the first picture and the second picture is compared, and when the similarity between the first picture and the second picture is greater than or equal to a preset similarity threshold, it can be considered that the terminal has not moved and the user is in an unrelieved state. When the similarity between the first picture and the second picture is smaller than a preset similarity threshold, the terminal can be considered to be moved, and the user may have obtained rescue.
In yet another embodiment, a first environment in which the user is located is obtained by the first picture, and a second environment in which the user is located is obtained by the second picture. When the first environment is the same as the second environment, the terminal is not considered to move, and the user is in a state of being not rescued; when the first environment and the second environment are different, it can be considered that the terminal is moved and the user may have obtained a rescue. For example, when furniture such as a sofa and a television is identified in the first picture, it can be determined that the first environment where the user is located is a living room; when furniture such as a bed and a wardrobe is identified in the second picture, the second environment where the user is located can be determined to be a room, and therefore the first environment and the second environment are different by comparing the first environment and the second environment, so that the terminal can be considered to be moved, and the user can obtain rescue. When the second environment is determined to be the living room, the terminal is considered not to move, and the user is not rescued.
In other alternative embodiments, it may be further determined whether the first picture and the second picture include rescuers, and it is determined whether the terminal moves by determining whether the rescuers can be identified from the first picture and the second picture. If the rescue workers can be identified from the first picture and the second picture, the terminal can be considered to be moved, and the user obtains rescue; if the rescue personnel can not be identified from the first picture and the second picture, the terminal can be considered not to move, and the user does not obtain rescue.
When other people except the user can be identified from the first picture and the second picture, the rescuers can be considered to be identified from the first picture and the second picture; when no other person except the user himself is recognized from the first picture and the second picture, it can be considered that the rescuer is not recognized from the first picture and the second picture. Preferably, the faces recognized from the first picture and the second picture may be compared with a preset face of the guardian, and when the faces recognized from the first picture and the second picture are the preset face of the guardian, it may be considered that the rescuers are recognized from the first picture and the second picture, and when the faces recognized from the first picture and the second picture are not the preset face of the guardian, it may be considered that the rescuers are not recognized from the first picture and the second picture. In the embodiment, when the rescue workers are identified, the user can be considered to be rescued, and the terminal moves; when the rescue personnel are not identified, the user can be considered to be not rescued, and the terminal does not move.
S15: and when the terminal is judged not to move, sending rescue information.
When the terminal is determined not to move through the judgment, the user can be considered not to obtain the rescue, and the rescue information needs to be sent at the moment. In one embodiment, when the terminal is not moved, the rescue information can be sent to the preset guardian. The rescue information can be a rescue telephone or a rescue short message, and optionally, the rescue short message also comprises at least one of pulse, heart rate and body temperature of the user, so that the rescuer can know the health state of the user in advance.
S16: and when the terminal is judged to move, the monitoring mode is exited.
If the terminal is detected to move, the user can be considered to be rescued, and the terminal can exit the monitoring mode at the moment.
Different from the situation in the prior art, in the monitoring method of this embodiment, after entering the monitoring mode, a first picture is obtained by a camera of the terminal, a second picture is obtained by the camera of the terminal after a preset time interval, whether the terminal has moved is determined by comparing the first picture and the second picture obtained at different times, and when it is determined that the terminal has not moved, it is determined that the user has not obtained a rescue, and therefore rescue information is sent. By the aid of the method, after the user falls down, whether the user is rescued or not is monitored, and the rescue information is sent again when the user is not rescued, so that safety of the user can be improved.
Referring to fig. 2, fig. 2 is a schematic flow chart of a fall monitoring method according to a second embodiment of the present application, the fall monitoring method specifically includes:
s21: a monitoring mode is entered.
Step S21 is the same as step S11, and is not repeated here.
S22: the method comprises the steps of obtaining a first picture and obtaining first position information of a terminal through a camera of the terminal.
The step of acquiring the first picture by the camera of the terminal is the same as step S12, and is not described herein again.
In this step, in addition to the first picture, first position information of the terminal is also obtained. Specifically, the terminal may obtain the geographical location of the terminal through any one of ppd (position meter Positioning device), GPS (Global Positioning System) satellite Positioning, bluetooth Positioning, WIFI (Wireless Fidelity) network Positioning, and GPRS (General Packet Radio Service)/CDMA (Code Division Multiple Access) mobile communication Positioning technologies, so as to obtain the first location information, which is not limited in this embodiment.
S23: and acquiring a second picture at preset time intervals through a camera of the terminal, and acquiring second position information of the terminal.
The step of acquiring the second picture by the camera of the terminal at the preset time interval is the same as the step S13, and is not described herein again.
After a preset time interval, in addition to acquiring the second picture, the second position information of the terminal is acquired in the step. Specifically, the terminal may obtain the geographical location of the terminal through any one of ppd (position meter Positioning device), GPS (Global Positioning System) satellite Positioning, bluetooth Positioning, WIFI (Wireless Fidelity) network Positioning, and GPRS (General Packet Radio Service)/CDMA (Code Division Multiple Access) mobile communication Positioning technologies, so as to obtain the first location information, which is not limited in this embodiment.
S24: and comparing the first picture with the second picture, and judging whether the terminal moves according to the comparison result.
Step S24 is the same as step S14, and is not repeated here.
S25: and when the terminal is judged not to move, sending rescue information.
Step S25 is the same as step S15, and is not repeated here. In this embodiment, preferably, the step of sending the rescue information is as shown in fig. 3, and specifically includes:
s251: and identifying the position of the terminal according to the first position information and the first picture.
When the terminal is judged not to move, the user can be considered to be still in a falling state, and rescue information needs to be sent again. The rescue information may be transmitted according to the environment in which the user is located when the rescue information is transmitted again. Alternatively, the environment in which the terminal is located may be determined according to the first picture and the first position information. The environment of the terminal can be judged according to the second picture and the second position information.
Specifically, when the first picture includes furniture and the first location information is a residential area, the environment where the terminal is located may be considered as a home. When the first picture includes a road or a vehicle, and the first location information is a street or a place such as a mall, the environment where the terminal is located may be considered as outdoor.
S252: and when the position of the terminal is at home, sending rescue information to a preset neighbor terminal.
When the location of the terminal is determined to be at home in step S251, in order to enable the user to obtain a rescue quickly, the rescue information may be sent to the preset neighbor terminal.
S253: and when the position of the terminal is outdoor, sending rescue information to a rescue center.
And when the position of the terminal is confirmed to be outdoor, the rescue information can be sent to a preset rescue center. Optionally, according to the outdoor geographical position of the user, a rescue center closest to the position of the user can be searched, and then a rescue message is sent to the closest rescue center, so that the user can be rescued in time.
S26: and when the terminal is judged to move, calculating the distance between the first position information and the second position information.
In this embodiment, whether the terminal moves is further determined by the first position information and the second position information, in order to avoid missing the optimal rescue opportunity for the user due to the misjudgment of the terminal after the terminal is determined to move by the first picture and the second picture. Specifically, a distance between the first position information and the second position information is calculated.
S27: and judging whether the distance is greater than or equal to a preset distance.
And judging whether the distance between the first position information and the second position information is greater than or equal to a preset distance. In this embodiment, the preset distance may be set according to specific situations. Alternatively, the preset distance may be 2m, 3m, 5m, 10m, and the like. And comparing the distance between the first position information and the second position information with a preset distance to judge whether the distance is greater than or equal to the preset distance.
S28: and if the distance is smaller than the preset distance, sending rescue information.
When it is confirmed that the distance between the first position information and the second position information is smaller than the preset distance, it can be considered that the terminal does not actually move, the user is still in an unrelieved state, and at this time, rescue information needs to be sent again.
S29: and if the distance is greater than or equal to the preset distance, exiting the monitoring mode.
If the distance between the first position information and the second position information is confirmed to be larger than or equal to the preset distance, the terminal is considered to have moved, the user is rescued, and therefore the monitoring mode can be quitted.
Different from the situation in the prior art, in the embodiment, whether the terminal moves is judged by comparing the first picture and the second picture acquired at different times, and when the terminal is judged not to move, the user can be considered not to be rescued, so that the rescue information is sent. And when the distance between the first position information and the second position information is judged to be smaller than the preset distance, the terminal is considered not to actually move, so that the rescue information is sent again, and the user is prevented from missing the optimal rescue opportunity. By the method, the safety of the user can be improved.
Referring to fig. 4, fig. 4 is a schematic flow chart of a third embodiment of the fall monitoring method according to the present application, in the embodiment, the fall monitoring method includes:
s41: a monitoring mode is entered.
Step S41 is the same as step S11, and is not repeated here.
S42: the first picture is obtained through a camera of the terminal, and the volume value of the first position of the terminal is obtained.
The step of acquiring the first picture by the camera of the terminal is the same as step S12, and is not described herein again.
Since the environment around the user may change before and after the user obtains the rescue and the volume value of the surrounding environment may also be different, whether the user obtains the rescue can be further confirmed by comparing the change of the volume value. And after entering the monitoring mode, acquiring the volume value of the first position of the terminal.
