For example, the characteristic information, service, scene, historical motion track, travel information, etc. referred to in this application are obtained under sufficient authorization.
Referring to fig. 1, a schematic diagram of an implementation environment of a scene recognition method according to an exemplary embodiment of the present application is shown; the implementation environment includes: a terminal 101 and a Near Field Communication (NFC) card reader 102, where the NFC card reader 102 is installed at an entrance of a target site and is used to control opening and closing of a checkpoint set at the entrance of the target site; the terminal 101 can communicate with the NFC reader 102 through its NFC chip included therein to request the NFC reader 102 to open a gate at an entrance, thereby enabling a target object to enter a target place. The target object may be a user or a robot, etc.
Wherein, the target place can be any place; for example, the target site is a residence, a parking lot, a transportation site or a vehicle, and the transportation site may be a passenger station, a train station, a high-speed rail station, an airport, or the like. For example, in the case where the target site is a residential site, the NFC reader 102 may be installed at a door of a home, a door of a building, a doorway of a cell, or the like. In the case where the target site is a parking lot, then the NFC reader 102 may be installed at a gate entrance of the parking lot. In the case where the target site is a transit station, then the NFC reader 102 may be installed at the gate entrance of the transit station. In the case where the target site is a vehicle, then the NFC reader 102 may be mounted at the door handle of the vehicle. The terminal 101101 is at least one of a mobile phone, a tablet computer, a watch, a bracelet and the like.
Referring to fig. 2, a flowchart illustrating a scene recognition method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S201: under the condition that the terminal enters the identification range of the NFC card reader, the terminal acquires first characteristic information of the NFC card reader.
The NFC card reader is installed at an entrance of a target place and used for controlling opening and closing of a barrier at the entrance, and the terminal is used for communicating with the NFC card reader through an NFC chip included in the terminal so as to request the NFC card reader to open the barrier at the entrance, so that a target object enters the target place.
Under the condition that the terminal enters the identification range of the NFC card reader, the terminal starts an NFC intelligent terminal identification (STR) function, and first characteristic information of the NFC card reader is identified through the NFC STR function. The first characteristic information may be any information used for representing the characteristics of the NFC card reader; for example, the first feature information may be a polling (polling) feature.
It should be noted that the communication reliability of the NFC STR function is high, and NFC is near field communication, which does not cause instability due to electromagnetic wave radiation in the air; therefore, the reliability can be improved by performing scene recognition through the NFC STR function.
Step S202: and the terminal matches the first characteristic information with a plurality of stored characteristic information, wherein the plurality of characteristic information are the characteristic information of the set scene.
The terminal determines the matching degree between the first characteristic information and the stored characteristic information to obtain a plurality of matching degrees; determining that the stored plurality of feature information includes target feature information matched with the first feature information under the condition that the target matching degree exists in the plurality of matching degrees, wherein the target matching degree is the matching degree exceeding the preset matching degree, and the target feature information is the feature information corresponding to the target matching degree, and executing the step S203; and when the target matching degree does not exist in the plurality of matching degrees, determining that the plurality of stored feature information do not include the target feature information, and ending.
Another point to be described is that, when there is no target matching degree in the multiple matching degrees, the terminal ends the scene recognition process and enters an unlocking process, that is, the terminal communicates with the NFC card reader based on the NFC chip to request the NFC card reader to open a checkpoint at an entrance of a target location, so that the target object enters the target location.
Step S203: and under the condition that the stored characteristic information comprises target characteristic information matched with the first characteristic information, the terminal enters a target scene corresponding to the target characteristic information, and the target scene is associated with a target place.
The terminal sets a corresponding relation between the characteristic information and the scene in advance; correspondingly; after the terminal determines the target characteristic information, the terminal determines a target scene corresponding to the target characteristic information from the corresponding relation between the characteristic information and the scene based on the target characteristic information, and then the terminal enters the target scene.
It should be noted that since the NFC chip is provided in a general terminal, the first feature information of the NFC card reader is obtained through the NFC chip, and scene recognition is performed based on the first feature information, and updating and iteration are not required to be performed on the terminal, which reduces the cost of scene recognition.
In the embodiment of the application, the NFC card reader is installed at the entrance of the target place, and the terminal enters the identification range of the NFC card reader, which indicates that the terminal is trying to swipe a card at the moment, and directly represents the action of the user entering the target place.
Referring to fig. 3, a flowchart illustrating a scene recognition method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S301: under the condition that the terminal enters the identification range of the NFC card reader, the terminal acquires first characteristic information of the NFC card reader.
The NFC card reader is installed at an entrance of a target place and used for controlling opening and closing of a checkpoint at the entrance, and the terminal is used for communicating with the NFC card reader through an NFC chip included in the terminal to request the NFC card reader to open the checkpoint at the entrance, so that a target object enters the target place. The target place is a residence, a parking lot, a transportation site or a vehicle, and the like. The transportation station can be a passenger station, a railway station, a high-speed rail station or an airport and the like.
And under the condition that the terminal enters the identification range of the NFC card reader, the terminal starts the STR function of the NFC, and the first characteristic information of the NFC card reader is identified through the STR function. The first feature information may be any information used for representing the features of the NFC card reader; for example, the first feature information may be a polling (polling) feature.
The point to be noted is that the communication reliability of the NFC STR function is high, and NFC is near field communication, so that the problem of instability due to electromagnetic wave air radiation does not exist; therefore, the reliability can be improved by performing scene recognition through the NFC STR function.
In a possible implementation manner, the NFC chip of the terminal is in an on state, so that whether the terminal enters the identification range of the NFC card reader or not is determined based on the NFC chip, and thus the timeliness of identification is improved. In another possible implementation manner, the NFC chip of the terminal is in an off state first, and the terminal switches the NFC chip from the off state to the on state only when the terminal is close to the entrance of the target location, so that power consumption of the terminal is saved. In another possible implementation manner, the NFC chip of the terminal is in an off state first, and when the terminal detects a gesture operation (for example, a gesture operation of raising the terminal) for turning on the NFC chip, the terminal switches the NFC chip from the off state to the on state, so that power consumption of the terminal is saved.
Wherein, the terminal determines whether the terminal is close to the entrance of the target place based on the Positioning mode of the Global Positioning System (GPS), and the process is as follows: the terminal positions the position of the terminal based on the GPS, and determines the distance between the terminal and the entrance of the target place based on the position of the terminal and the position of the entrance of the target place; determining that the terminal is close to an entrance of a target place under the condition that the distance is smaller than a first preset distance; and under the condition that the distance is not less than the first preset distance, determining that the terminal is not close to the entrance of the target place.
It should be noted that the target site is a residence, a parking lot, a transportation site, or a vehicle; when the target place is a residence, a parking lot or a vehicle, the user generally enters the target place during the off-duty time; when the destination location is a transportation station, the user generally enters the destination location at a corresponding time when purchasing tickets in advance. Correspondingly, the terminal may control the turning on of the NFC chip in combination with the time information or the riding information, and the process may include at least one of the following implementation manners:
the terminal determines a first time range based on the historical motion track of the target object, wherein the first time range is a time range in which the target object is likely to enter a target place; and under the condition that the current moment is within the first time range, the terminal switches the NFC from the off state to the on state.
The terminal determines a second time range based on the travel information of the target object, wherein the second time range is a time range in which the target object is likely to enter the target place; and under the condition that the current moment is within the second time range, the terminal switches the NFC from the off state to the on state.
Step S302: and the terminal matches the first characteristic information with a plurality of stored characteristic information, wherein the plurality of characteristic information are the characteristic information of the set scene.
The terminal comprises an application processor, and the application processor stores the characteristic information of the set scene. After the terminal acquires the first feature information, the first feature information is reported to the application processor, the application processor matches the first feature information with the stored feature information and returns a matching result to the terminal, and the matching result is used for indicating whether the stored feature information comprises target feature information matched with the first feature information or not.
In a possible implementation manner, the terminal directly matches the characteristic information, so that a matching result is determined; in another possible implementation manner, the terminal may allocate index information to the feature information, where the index information is used to uniquely identify the feature information, but the index information is simpler than the feature information, so that matching of the feature information is performed based on the simple index information, the calculation amount of feature matching can be reduced, and matching efficiency is improved. Correspondingly, the step of the terminal matching the first feature information with the stored plurality of feature information may be implemented by the following steps (1) to (3), including:
(1) the terminal determines first index information corresponding to the first characteristic information, wherein the first index information is used for uniquely identifying the first characteristic information, but the complexity of the first index information is lower than that of the first characteristic information.
The first index information may be a number or description information of a target location corresponding to the first feature information, and in the embodiment of the present application, a specific form of the first index information is not particularly limited. For example, if the index information is represented by a number, the first index information corresponding to the first feature information is shown in table 1 below:
TABLE 1
| Target site | Residential area | Parking lot | Traffic station | Vehicle with a steering wheel |
| First index information corresponding to first characteristic information | 0 | 1 | 2 | 3 |
For another example, if the index information is represented by description information, the first index information corresponding to the first feature information is shown in table 2 below:
TABLE 2
| Target site | Residential area | Parking lot | Traffic station | Vehicle with a steering wheel |
| First index information corresponding to first characteristic information | Home-use | Parking lot | High-speed rail station | Vehicle with a steering wheel |
(2) The terminal matches the first index information with a plurality of stored index information, the plurality of stored index information are index information corresponding to the plurality of characteristic information, and one index information corresponds to one characteristic information.
For example, if the index information is represented by a numeral and the target location is a residence, the first index information corresponding to the first feature information is 0, and the stored index information is 0, 1, 2, and 3; the terminal directly matches 0 with the stored 0, 1, 2, and 3.
If the index information is represented by the description information and the target place is a residence, the first index information corresponding to the first feature information is 'home', and the stored index information is 'home', 'parking lot', 'high-speed rail station' and 'vehicle'; the terminal directly matches the stored "home", "parking lot", "high-speed rail station" and "vehicle".
(3) When the plurality of index information includes target index information matched with the first index information, the terminal determines that the plurality of stored feature information includes target feature information, and the target feature information is feature information corresponding to the target index information.
If the stored plurality of feature information includes target feature information matching the first feature information, step S303 is executed; and when the target index information is not included in the plurality of index information, the terminal determines that the target characteristic information is not included in the plurality of stored characteristic information, and the operation is finished.
In another possible implementation manner, the terminal screens out second feature information from the stored plurality of feature information, and matches the first feature information with the screened out second feature information, so as to determine whether the target feature information exists. The number of the second characteristic information is small; therefore, the first feature information is matched with the screened second feature information, the calculation amount of feature matching can be reduced, and the matching efficiency is improved. The step of screening out the second feature information from the stored plurality of feature information by the terminal may be:
the terminal screens out second characteristic information from the plurality of second characteristic information based on the current position of the terminal and the positions corresponding to the plurality of characteristic information, wherein the position corresponding to any one characteristic information is the position of the NFC card reader corresponding to the characteristic information; the distance between the position corresponding to the second characteristic information and the current position is smaller than a second preset distance.
Step S303: and under the condition that the stored plurality of feature information includes target feature information matched with the first feature information, the terminal communicates with the NFC card reader based on the NFC chip to request the NFC card reader to perform identity authentication on the NFC chip.
The terminal sends the identity information of the NFC chip to the NFC card reader based on the communication connection between the NFC chip and the NFC card reader; under the condition that the NFC card reader determines that the terminal has the authority to enter the target place based on the identity information, the NFC card reader sends a confirmation message to the terminal, wherein the confirmation message is used for indicating that the identity authentication of the NFC chip is passed; and under the condition that the NFC card reader determines that the terminal does not have the authority to enter the target place based on the identity information, the NFC card reader sends a negative message to the terminal, wherein the negative message is used for indicating that the identity verification of the NFC chip does not pass. Correspondingly, when the terminal receives the confirmation message sent by the NFC card reader, the terminal determines that the NFC card reader passes the authentication of the NFC chip, and the step S304 is executed; and under the condition that the terminal receives the negative message sent by the NFC chip, the terminal determines that the NFC card reader does not pass the authentication of the NFC chip, and the process is finished.
Step S304: and under the condition that the NFC card reader passes the authentication of the NFC chip, the terminal enters a target scene corresponding to the target characteristic information, and the target scene is associated with a target place.
The target place is a residence, a parking lot, a transportation site or a vehicle, etc. The terminal sets a corresponding relation between the characteristic information and the scene in advance; correspondingly; after the terminal determines the target characteristic information, the terminal determines a target scene corresponding to the target characteristic information from the corresponding relation between the characteristic information and the scene based on the target characteristic information, and then the terminal enters the target scene.
The first implementation mode comprises the following steps: if the target place is a residence, the target scene is used for controlling the intelligent household equipment in the residence; correspondingly, the step of the terminal entering the target scene corresponding to the target characteristic information may be: the terminal controls the intelligent household equipment to execute the first target operation. For example, the smart home device is at least one of a smart router and a smart lamp; the terminal controls the intelligent router to be in the starting state and/or controls the intelligent lamp to turn on the light.
The terminal can control the smart home equipment to execute a first target operation and can also control the smart home equipment to execute a fourth target operation; for example, the terminal turns on the WiFi module, sets to a mute mode, or releases the mute mode, etc.
The second implementation mode comprises the following steps: if the target place is a parking lot, the target scene is used for controlling the content displayed by the terminal; correspondingly, the step of the terminal entering the target scene corresponding to the target feature information may be: the terminal displays an electronic map of the parking lot, where the electronic map may be a two-dimensional (2D) map or a three-dimensional (3D) map, and in this embodiment, a display format of the map is not particularly limited.
The third implementation mode comprises the following steps: if the target scene is a transportation station, the target scene is used for controlling the content displayed by the terminal; correspondingly, the step of the terminal entering the target scene corresponding to the target characteristic information may be: and the terminal displays the riding information corresponding to the current login account at the transportation station, wherein the riding information comprises at least one item of train number information, time information, seat information and platform information. The terminal can display the riding information and navigation information, wherein the navigation information is the navigation information from the current position of the terminal to the platform information.
The terminal can display the riding information in one screen, or pop up a display frame on the terminal, and the riding information is displayed in the display frame. In the embodiment of the present application, a specific manner of displaying the riding information by the terminal is also not specifically limited.
The fourth implementation mode comprises the following steps: if the target place is a vehicle, the target scene is used for controlling the vehicle; correspondingly, the step of the terminal entering the target scene corresponding to the target feature information may be: the terminal establishes a short-range communication connection with a vehicle-mounted terminal of the vehicle, and controls the vehicle-mounted terminal to execute a second target operation based on the short-range communication connection.
The short-distance communication connection can be a Bluetooth connection or a WiFi connection; the step of controlling the vehicle-mounted terminal to execute the second target operation by the terminal comprises at least one of the following implementation modes:
the terminal controls the vehicle-mounted terminal to open the navigation application;
and the terminal controls the vehicle-mounted terminal to open the audio playing application.
One point to be noted is that, if the target location is a vehicle, the target scene is used for controlling the vehicle; correspondingly, the step of the terminal entering the target scene corresponding to the target feature information may be: the terminal establishes a short-range communication connection with an in-vehicle terminal of the vehicle, and controls an in-vehicle device of the vehicle to perform a third target operation based on the short-range communication connection. The in-vehicle device may be a vehicle seat, and accordingly, the step of the terminal controlling the in-vehicle device of the vehicle to perform the third target operation may be: and the terminal controls the vehicle seat to heat.
The terminal is provided with a corresponding relation between the characteristic information and the scene in advance; moreover, the corresponding relation can be agreed with a user through a scene configuration interface; correspondingly, the process of setting the corresponding relationship between the feature information and the scene by the terminal may be:
the terminal displays a scene configuration interface, the scene configuration interface is used for configuring the corresponding relation between the characteristic information and the scene, and the scene configuration interface comprises the characteristic information of the NFC card reader identified by the terminal history and the place information of the place where the NFC card reader is located; based on the location information, the configured scene is obtained, and the corresponding relation between the characteristic information and the scene is established.
In the embodiment of the application, a user can configure the corresponding relation between the feature information and the scene through the scene configuration interface, so that personalized setting can be realized.

The terminal sets a corresponding relation between the scene corresponding service and the first time length in advance; correspondingly, the terminal acquires the first duration of the service corresponding to the target place from the corresponding relation between the service and the first duration based on the service corresponding to the target scene.
In a first implementation manner, a target place is a residence, and a target scene is used for controlling intelligent household equipment included in the residence; the service is the service provided by the intelligent household equipment; for example, the smart home device is an intelligent router or an intelligent lamp; the time required for the operation of opening the intelligent router or opening the intelligent lamp is short, so that the first time length of the service corresponding to the target scene can be set to be short; for example, the first time period is 2 seconds, 5 seconds, or the like.
In a second implementation mode, a target place is a parking lot, and a target scene is used for controlling contents displayed by a terminal; the service is a service corresponding to the electronic map of the parking lot displayed by the terminal; the operation of displaying the electronic map by the terminal requires shorter time; therefore, the first duration of the service corresponding to the target scene can be set to be shorter duration; for example, the first time period is 3 seconds, 4 seconds, or the like.
In the third implementation mode, the target site is a transportation station, and the target scene is used for controlling the content displayed by the terminal; the service is a service corresponding to the riding information displayed by the terminal; the operation time for displaying the riding information by the terminal is short; therefore, the first duration of the service corresponding to the target scene can be set to be a shorter duration; for example, the first time period is 2 seconds, 3 seconds, or the like.
In a fourth implementation mode, the target place is a vehicle, and the target scene is used for controlling the vehicle; the service is that the vehicle-mounted terminal executes the service corresponding to the second target operation or the vehicle-mounted device executes the service corresponding to the third target operation; since the time required for the in-vehicle terminal to perform the second target operation is also short, the first time period may be set to a short time period; for example, the first duration is 2 seconds or 3 seconds; the time required for the in-vehicle device to perform the third target operation is longer, and therefore, the first period of time can be set to a longer period of time; for example, the first period of time is 5 minutes or 10 minutes, etc.
Step S404: and the terminal acquires a second time length, wherein the second time length is the time length required by the target object from the entrance of the target place to the acquisition of the service.
The terminal determines the second duration based on a distance between a location at an entrance of the target location and a location corresponding to providing the service, and a moving speed of the target object. And the terminal determines the ratio of the distance to the moving speed as a second time length.
Wherein the moving speed of the target object can be determined based on the type of the target place; accordingly, the step of the terminal determining the moving speed of the target object may be: and acquiring the moving speed matched with the type of the target place. For example, if the target location is a residential area, the moving speed of the target object is the walking speed of the user. If the target location is a parking lot, the moving speed of the target object is the traveling speed of the vehicle, and the traveling speed is not higher than the speed limit of the parking lot. If the target site is a transportation station, the moving speed of the target object is the walking speed of the user. If the target location is a vehicle, the moving speed of the target object is the walking speed of the user.
Step S405: the terminal determines a time stamp based on the first duration and the second duration, wherein the time stamp is the starting time of entering the target scene.
Under the condition that the first time length is longer than the second time length, the time length required for responding to the service is longer, at the moment, the target scene needs to be entered as soon as possible, and the terminal determines the time stamp as the current time; when the first duration is equal to the second duration, it is described that the duration required for responding to the service is the same as the duration required for the target object to reach the location of the service, and the terminal determines the time of the first duration (or the second duration) after the current time as the timestamp. And under the condition that the first time length is less than the second time length, the time length required for the target object to reach the place where the service is located is longer, the target object can enter the target place after a while, the terminal determines the time length difference between the second time length and the first time length, and the time of the time length difference after the current time is determined as the time stamp.
Step S406: and the terminal enters the target scene at the timestamp.
In the embodiment of the application, the starting time of entering the target scene is determined firstly, and the time of entering the target scene at the starting time can be accurately controlled, so that the increase of energy consumption caused by too early entering the target scene can be avoided, and the condition that a user cannot timely enjoy the service corresponding to the target scene can be avoided.

step S501: and under the condition that the terminal enters the identification range of the NFC card reader, the terminal communicates with the NFC card reader based on the NFC chip to request the NFC card reader to carry out identity authentication on the NFC chip.
It should be noted that the step of the terminal communicating with the NFC card reader based on the NFC chip to request the NFC card reader to perform authentication on the NFC chip is the same as the step of the terminal communicating with the NFC card reader based on the NFC chip to request the NFC card reader to perform authentication on the NFC chip in step S303, and details are not repeated here.
Step S502: and under the condition that the NFC card reader passes the identity authentication of the NFC chip, the terminal acquires first characteristic information of the NFC card reader.
It should be noted that the step of acquiring the first feature information of the NFC card reader by the terminal is the same as the step of "acquiring the first feature information of the NFC card reader by the terminal" in step S301, and is not described herein again.
Step S503: and the terminal matches the first characteristic information with the stored characteristic information, wherein the stored characteristic information is the characteristic information of the set scene.
It should be noted that step S503 is the same as step S302, and is not repeated herein.
Step S504: and under the condition that the stored characteristic information comprises target characteristic information matched with the first characteristic information, the terminal enters a target scene corresponding to the target characteristic information, and the target scene is associated with a target place.
