The embodiment of the disclosure provides a wake-up method and a wake-up device capable of applying the same. The method is applied to an electronic device having a first sensor and a second sensor. The method includes the following operations. It is determined whether the first sensor detects the entry of the target object into the first zone. In response to the first sensor detecting that the target object enters the first area, it is determined whether a preset event has occurred. And responding to the occurring preset event, and sending a wake-up instruction to the second sensor so as to wake up the second sensor to identify the target object.
Fig. 1 schematically shows an application scenario of a wake-up method and a wake-up apparatus according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, many users now have a habit that they will set the computer to a standby state when they leave their own computer for a short time, and will wake up the computer quickly by object recognition when they come back again.
In the process of implementing the embodiments of the present disclosure, the inventors found that: the object recognition speeds of the sensors of different products are almost the same, and users have the feeling that some products have a Time of flight (TOF) module, some products do not have the TOF module, and the products with the TOF module can make users feel that the object recognition speed is relatively slow.
Further, in the process of implementing the embodiments of the present disclosure, the inventors found that: in the existing electronic device with the TOF module, once the TOF module detects a user, the TOF module immediately wakes up the object recognition module to perform object recognition, but since the user does not enter the object recognition area at this time, the user cannot be recognized in advance even if the TOF module wakes up the object recognition module to perform object recognition, and the TOF module wakes up the object recognition module to perform object recognition in advance, so that the user feels that the waiting time is too long, and further feels that the object recognition speed of the electronic device is relatively slow.
In view of the above, the embodiments of the present disclosure provide an improved wake-up method for waking up an object identification module of an electronic device. By the aid of the awakening method, when the TOF module detects the target object, the TOF module does not awaken the object identification module to identify the object, and then awakens the object identification module to identify the object after the target object enters the object identification area, so that a user can identify the object at the moment when the object identification module is awakened.
The present disclosure will be described in detail below with reference to specific examples.
Fig. 2A schematically shows a flow chart of a wake-up method according to an embodiment of the present disclosure.
The wake-up method is applied to an electronic device having a first sensor (e.g., a TOF module) and a second sensor (e.g., an object recognition module). As shown in fig. 2A, the method may include operations S210 to S230, for example.
It is noted that in embodiments of the present disclosure, the first sensor may be, for example, a TOF module that detects the target object by TOF 3D imaging. Among them, the so-called TOF 3D imaging is to obtain the distance of a target object by continuously transmitting light pulses to the target object and then receiving light returning from the target object with a sensor and by detecting the flight (round trip) time of the light pulses. The second sensor may be, for example, an object recognition module capable of object recognition.
In the disclosed embodiments, the target object may be, for example, a user of the electronic device.
In operation S210, it is determined whether the first sensor detects that the target object enters the first area.
In embodiments of the present disclosure, the first area may be, for example, a detection zone of the first sensor.
Specifically, the first sensor may detect the target object when the target object enters the first area, and the first sensor may not detect the target object when the target object is outside the first area.
TOF representation, as shown in FIG. 2BFirst sensor of notebook computer, using O 1 Denotes, camera denotes a second sensor of the notebook computer, with O 2 Representation of angle aO 1 The area limited in b represents the detection area of TOF, and the angle cO 2 The area defined within d represents the recognition region of Camera.
In operation S220, it is determined whether a preset event occurs in response to the first sensor detecting that the target object enters the first area.
Specifically, once it is detected by the first sensor that the target object enters the first area, it is further determined whether a preset event occurs. Wherein if it is determined that the preset event has occurred, jumping to operation S230; if the preset event is determined not to have occurred, whether the preset event has occurred continues to be detected.
It should be noted that, in the embodiment of the present disclosure, whether the preset event occurs may be determined in various ways. For example, whether a preset event occurs may be determined by means of the manner 1 or the manner 2 described below.
In the mode 1, whether the current time is a preset time is determined, wherein the preset time is a time after a preset time is delayed from the time when the target object enters the first area.
Specifically, assume that the time when the target object enters the first area is T 1 If the preset delay time (i.e. the preset time) is T, then the preset time in the mode 1 is T 2 ＝T 1 +t。
Based on the method 1, after the target object enters the first area, the time of the target object entering the first area can be recorded, and the formula T is utilized 2 ＝T 1 + T calculating to obtain preset time T 2 Then, whether the current time reaches the preset time T or not is detected 2 . Wherein if it is detected that the current time has reached the preset time T 2 Otherwise, the operation jumps to operation S230, and otherwise, the current time is continuously detected whether the current time reaches the preset time T 2 Until the current moment is detected to reach the preset moment T 2 Until now.
The preset duration can roughly represent the target object from T 1 The time required for the position at which the time is located to move to the second area,therefore, by means of the method 1, the time when the target object enters the identification area of the second sensor can be estimated, and the second sensor can be woken up at the time to identify the target object, so that the user can complete object identification at the moment when the object identification module is woken up.
Mode 2, it is determined whether the first sensor detects that the target object enters a second area, where the second area is an area where the second sensor can recognize the target object.
Specifically, in mode 2, the first sensor may determine whether the target object has entered the second area from the first area by tracking the trajectory of the target object after detecting that the target object has entered the first area. Wherein the second area may be, for example, an object recognition area of the second sensor. Wherein if it is determined that the target object has entered the second area from the first area, jumping to operation S230, otherwise, continuing to track the trajectory of the target object until it is determined that the target object has entered the second area from the first area.
In operation S230, a wake-up instruction is transmitted to the second sensor in response to the occurrence of the preset event, thereby waking up the second sensor to identify the target object.
Unlike the related art in which the second sensor starts to be woken up for object recognition once the target object enters the detection area of the first sensor, in the embodiment of the present disclosure, the second sensor is not woken up immediately for object recognition when the target object enters the detection area of the first sensor, but is woken up again for object recognition when it is determined or estimated that the target object has entered the recognition area of the second sensor, thereby enabling the user to complete object recognition at the moment when the object recognition module is woken up.
The method of FIG. 2A is further described with reference to FIG. 3 in conjunction with specific embodiments.
As an alternative embodiment, determining whether the first sensor detects the target object entering the first area in operation S210 may include, for example: it is determined whether the first sensor detects the target object entering the first area from a side near the first sensor.
As shown in fig. 2B, set at coordinate point O for TOF 1 Where Camera is set at coordinate point O 2 If the target object enters the detection zone of the TOF from the left side of the figure, the target object is considered to have entered the first area from the side close to the first sensor; if the target object enters the detection region of the TOF from the right side of the graph, the target object is considered to have entered the first region from the side near the second sensor.
Specifically, when determining whether the target object enters the first area from the side close to the first sensor or the side close to the second sensor, the coordinate point O at which the target object enters the first area may be determined first by TOF ranging 3 Then calculating the coordinate point O by the distance formula 1 And the coordinate point O 3 Distance L between 1 And a coordinate point O 2 And the coordinate point O 3 A distance L therebetween 2 And finally comparing L 1 Whether or not less than L 2 . If L is 1 Less than L 2 The target object is considered to have entered the first area from the side close to the first sensor, otherwise if L is 1 Greater than L 2 The target object is considered to have entered the first area from the side close to the second sensor.
Alternatively, the coordinate point O at which the target object is located when entering the first area is determined by TOF ranging 3 Afterwards, the coordinate point O can also be compared 1 And O 3 Abscissa and coordinate point O of 2 And O 3 Determines whether the target object enters the first area from the side near the first sensor or from the side near the second sensor. Wherein, if X is 1 -X 3 Less than X 2 -X 3 The target object is considered to have entered the first area from the side close to the first sensor, otherwise if X is 2 -X 3 Less than X 1 -X 3 Then the target object is considered to enter the first area from the side close to the second sensor, where X 1 Represents a coordinate point O 1 Abscissa of (2), X 2 Represents a coordinate point O 2 Abscissa of (2), X 3 Represents a coordinate point O 3 The abscissa of (a).
It should be noted that the above method for determining whether the target object enters the first area from the side close to the first sensor or the side close to the second sensor is applicable to both the electronic device used in the shell mode (i.e. the normal use mode of the laptop computer) and the electronic device used in the tent mode, and will not be illustrated here.
Due to practical use, the target object may approach the electronic device from one side of the electronic device (e.g., the side near the first sensor) and may approach the electronic device from the other side of the electronic device (e.g., the side near the second sensor).
As shown in fig. 2B, since it takes a certain time to move from the first area to the second area when the target object approaches the electronic device from the side close to the first sensor, the target object may first enter the first area, and in order to avoid that the user feels that the object recognition speed of the electronic device is slow, in this case, the second sensor may not be woken up first after the first sensor detects the target object, but may be woken up after a predetermined time is delayed.
When the electronic device is close to the electronic device from the side close to the second sensor, the target object enters the first area and enters the second area at the same time, that is, no time is consumed when the target object moves from the first area to the second area.
That is, as an optional embodiment, the method may further include, for example: and immediately sending a wake-up instruction to the second sensor in response to the first sensor detecting that the target object enters the first area from the side close to the second sensor.
Through the embodiment of the disclosure, when the target object enters the first area from the side close to the second sensor, it indicates that the target object has entered the second area, and at this time, if the target object enters the first area from the side close to the first sensor, delaying and then waking up the second sensor may make the user feel that the object recognition speed of the electronic device is relatively slow, so in order to avoid such a situation, the second sensor may be directly woken up for object recognition without delaying.
As an alternative embodiment, the method may further include, for example: and determining a preset time length. Wherein determining the preset duration may for example comprise the following operations.
A distance between the target object and the electronic device is determined.
And determining the preset time length according to the determined distance.
Specifically, for convenience of calculation, the distance of the target object to the straight line on which the first sensor and the second sensor are located may be taken as the distance of the target object to the electronic device.
Because the distances are different, the time consumed by the user from entering the detection area of the first sensor to entering the identification area of the second sensor to the position just facing the second sensor is also different, so that different delay preset times can be set according to different distances through the embodiment of the disclosure, and the user can be ensured to wake up the second sensor for object identification when reaching the position just facing the second sensor in the identification area as far as possible.
As an alternative embodiment, determining the preset time period according to the determined distance may include, for example, the following operations.
And taking the first time length as a preset time length in response to the fact that the determined distance is larger than a first threshold and smaller than or equal to a second threshold.
And in response to the determined distance being less than or equal to the first threshold, setting a second duration shorter than the first duration as a preset duration.
And in response to the determined distance being greater than the second threshold and less than or equal to a third threshold, taking a third duration that is longer than the second duration as the preset duration.
Fig. 3 schematically shows a diagram relating distance and delay time according to an embodiment of the present disclosure.
As shown in FIG. 3, O 1 Representing a first sensor (e.g. TOF), O 2 Representing a second sensor (e.g., camera),. Alpha.aO 1 b is a representation of the area defined withinThe detection zone (i.e., the first zone) of the first sensor, < cO 2 The area defined within d represents the identification area of the second sensor (i.e., the second area), and 1 represents O 1 And O 2 On a straight line, the straight line e and the straight line l are perpendicular to the point O 1 The straight line f is perpendicular to the straight line l at the point O 2 Line j is perpendicular to line l 1 、l 2 、l 3 Are all perpendicular to the line j. Wherein l 1 、l 2 、l 3 The distances to the line l are 400mm, 600mm, 800mm, respectively. Wherein, from A 1 The delay preset time to A2 may be set to t 1 From A 3 To A 4 The delay preset time of may be set to t 2 From A 5 To A 6 The delay preset time of may be set to t 3 . In particular, t 1 、t 2 And t 3 Can be estimated based on the average moving speed of most users, and t 1 ＜t 2 ＜t 3 。
For example, t may be set when the distance from the target object to the electronic device is 400mm or less 1 As a delay preset time; when the distance from the target object to the electronic device is greater than 400mm and less than or equal to 600mm, t can be adjusted 2 As a delay preset time; when the distance from the target object to the electronic equipment is more than 600mm and less than or equal to 800mm, t can be adjusted 3 As a delay preset time, etc.
It should be noted that the method for determining the preset duration according to the determined distance is applicable to electronic devices used in a shell mode (i.e., a normal use mode of a laptop computer) and a tent mode, and is not illustrated here.
