It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for switching operating modes of an electronic device is shown in accordance with the present disclosure. The method for switching the working mode of the electronic equipment comprises the following steps:
In the present embodiment, the execution subject of the method for switching the operation mode of the electronic device (such as the terminal device 101 shown in fig. 1) may acquire the target image by a wired connection manner or a wireless connection manner. The target image usually displays a first preset body part and a second preset body part of a target person. The preset body part may include, but is not limited to, at least one of the following: left and right arms, torso, left and right legs. The first predetermined body part and the second predetermined body part may be generally determined from the predetermined body parts. The target person may be any person specified in advance according to actual application requirements (for example, a person with preset unlocking authority), or the target person may be a person specified according to rules (for example, a person in a camera shooting area).
As an example, the execution subject may acquire a target image in which a first preset body part and a second preset body part of the target person are photographed from a built-in camera. As yet another example, the execution subject of the method for switching the operation mode of the electronic device may also be the server 103 as shown in fig. 1. The server 103 may acquire a target image photographed by a built-in camera from the terminal apparatus 101.
In some optional implementations of this embodiment, the first predetermined body part may include a head. The head may include, but is not limited to, a forward face and a lateral (offset angle within a preset threshold) face of a person.
In some optional implementations of this embodiment, the second predetermined body part may include a hand. Optionally, the hand can be further subdivided into a left hand or a right hand.
In this embodiment, the executing entity may determine the position relationship between the first preset body part and the second preset body part of the target person displayed in the target image acquired in step 201 in various ways.
As an example, the executing subject may input the target image obtained in step 201 into a pre-trained object detection model, and obtain coordinates of the first preset body part and the second preset body part displayed in the target image respectively. Then, the executing body may determine a positional relationship between the first preset body part and the second preset body part of the target person according to the coordinates. The above positional relationship may include, but is not limited to, at least one of: an up-down relationship (e.g., left hand position high above right hand), a left-right relationship (e.g., left hand to the left of the head in the horizontal direction), an intersecting relationship (e.g., left and right arms intersect), a parallel relationship (e.g., left and right arms in a lateral recumbent position).
The pre-trained object detection model may be obtained by training an initial model by using various object detection (object detection) algorithms. Wherein, the target detection algorithm may include, but is not limited to, at least one of the following: RCNN (regions with conditional Neural network feature) algorithm, Yolo (You Only Look Online: Unified, Real-Time Object Detection) algorithm, SSD (Single Shot MultiBox Detector) algorithm.
In some optional implementations of this embodiment, based on that the first preset body part may include a head, the executing main body may determine a positional relationship between the first preset body part and the second preset body part of the target person according to the following steps:
firstly, zooming a target image to generate a first image to be detected.
In these implementations, the executing body may scale the target image acquired in step 201 to generate a first image to be detected. The resolution of the first image to be detected may be smaller than the resolution of the target image.
It should be noted that the resolution of the first image to be detected is generally matched with the resolution of the input image of the human head detection model described below.
In the second step, the position of the head displayed on the first image to be detected is determined.
In these implementations, the execution subject may determine the position where the head is displayed on the first image to be detected, by a head detection model based on deep learning. The head detection model can be used for representing the corresponding relation between the image to be detected and the head position. The above-mentioned positions may be generally expressed in the form of coordinates.
Based on the optional implementation mode, because the characteristics of the head or the face of the human body are obvious, the detection is performed through a small resolution, so that the expenditure of computing resources can be reduced on the premise of ensuring the accuracy, and the detection speed is increased.
And thirdly, determining the position of a second preset body part based on the target image.
In these implementations, based on the target image, the execution subject may determine the location of the second preset body part in various ways. As an example, the execution subject may input the target image to a detection model trained in advance and detected for the second preset body part, and obtain a position of the second preset body part. The detection model can be used for representing the corresponding relation between the image to be detected and the position of the second preset body part. The above-mentioned positions may be generally expressed in the form of coordinates.
Optionally, based on that the second preset body part may include a hand, the executing subject may determine the position of the second preset body part according to the following steps:
and S1, zooming the target image to generate a second image to be detected.
In these implementations, the executing body may scale the target image obtained in step 201 to generate a second image to be detected. The resolution of the second image to be detected may be greater than the resolution of the first image to be detected.
The resolution of the second to-be-detected image is generally matched with the resolution of the input image of the hand detection model described below.
And S2, determining the position of the hand displayed on the second image to be detected.
In these implementations, the execution body may determine the position of the hand displayed on the second image to be detected in various ways.
For example, the execution body inputs the second image to be detected to a hand detection model trained in advance, and obtains the position of the hand. The hand detection model can be used for representing the corresponding relation between the image to be detected and the position of the hand. The above-mentioned positions may be generally expressed in the form of coordinates.
It should be noted that the hand detection model may include various pre-trained deep learning models, such as a BlazePalm model (palm detector model published by google), a hand detection model trained based on a key point detection model of a hand published by cmu performance Computing Lab (university of california) of the united states of america.
Based on the above alternative implementation, since the features of the hand are more difficult to detect than the head, the accuracy of detection can be ensured by detecting with a greater resolution than head detection.
And fourthly, determining the position relation between the head of the target person and the second preset body part according to the position of the head displayed on the first image to be detected and the position of the second preset body part.
In these implementations, the execution subject described above may determine the positional relationship between the head of the target person and the second preset body part in various ways, according to the position where the head is displayed on the first image to be detected and the position of the second preset body part.
As an example, the executing body may determine the coordinates of the head and the second preset body part in the same coordinate system according to the scaling of the first image to be detected and the target image and the position of the second preset body part. Then, the executing body may determine a positional relationship between the head of the target person and a second preset body part based on the determined coordinates.
Alternatively, the executing body may determine the positional relationship between the head and the hand in a manner similar to that described above, based on the scaling of the first image to be detected and the target image and the scaling of the second image to be detected and the target image.
And step 203, switching the working mode of the electronic equipment according to the indication of the preset mode switching condition based on the matching between the position relation and the preset mode switching condition.
In this embodiment, based on the matching between the position relationship and the preset mode switching condition, the execution main body may switch the operating mode of the electronic device in various ways according to the instruction of the preset mode switching condition. The preset mode switching condition may include a preset positional relationship between the first preset body part and the second preset body part. The preset mode switching condition may be used to instruct the electronic device to switch between specific operating modes after the condition is satisfied. The above-mentioned operation modes may include, but are not limited to, at least one of the following: standby mode, screen locking mode and running mode. The screen locking mode can be used for representing a state that the background program is allowed to run but interaction operations except unlocking are not responded. The above-mentioned operation mode can be used for characterizing the normal working state of the electronic equipment.
In this embodiment, in response to determining that the position relationship satisfies the preset mode switching condition, the executing body may switch the operating mode of the electronic device according to an instruction of the preset mode switching condition. As an example, the preset mode switching condition may be a preset unlocking condition. The preset unlocking condition may include, for example, that the right hand is located at the upper right of the head. In response to determining that the position relationship determined in step 202 satisfies the preset unlocking condition, the execution main body may perform switching of the working mode according to an instruction of the preset unlocking condition (for example, switching from the screen locking mode to the running mode).
In some optional implementations of the embodiment, the preset mode switching condition may include a preset position relationship condition and a preset hand form condition.
Based on the optional implementation manner, according to the instruction of the preset mode switching condition, the execution main body may switch the operating mode of the electronic device according to the following steps:
first, whether the position relation meets a preset position relation condition and whether the shape of the hand meets a preset hand shape condition is determined.
In these implementations, the executive may determine the shape of the hand in the target image using a pre-trained hand shape recognition model. Then, the execution subject may determine whether the hand shape in the target image satisfies a preset hand shape condition in various ways. The preset hand shape condition may include a preset hand shape. The preset hand shapes may include, but are not limited to, at least one of the following: open palm, fist, V-shaped.
In these implementations, the executing body may also determine whether the positional relationship determined in step 202 satisfies the preset positional relationship condition in various ways.
The hand shape recognition model may include various models for image recognition, such as a deep learning model.
It should be noted that the determination of whether the two conditions are satisfied may be performed simultaneously or sequentially, and is not limited herein.
And secondly, responding to the fact that the position relation meets the preset position relation condition and the hand form meets the preset hand form condition, and switching the working mode of the electronic equipment according to the indication of the preset mode switching condition.
In these implementations, in response to determining that the first step satisfies the preset position relationship condition and the preset hand form condition, the execution main body may switch the operating mode of the electronic device in various ways according to the instruction of the preset mode switching condition. As an example, the preset mode switching condition is a preset sleep condition. The preset sleep condition may be used to indicate that the operation mode is switched to the standby mode after the condition is satisfied.
It should be noted that the execution subject of the method for switching the operating mode of the electronic device may also be the server 103 shown in fig. 1. The server 103 may send, to the terminal apparatus 101, information indicating that the electronic apparatus switches the operating mode according to an instruction of the preset mode switching condition in response to determining that the positional relationship satisfies the preset mode switching condition.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of a method for switching an operation mode of an electronic device according to an embodiment of the present disclosure. In the application scenario of fig. 3, the user 301 holds up the left hand against the smart terminal device 302. The smart terminal apparatus 302 may be provided with a camera 3021, a display screen 3022, and a speaker 3023. The smart terminal apparatus 302 can capture an image 303 containing the head and the hand of the user 301 through the camera 3021. Thereafter, the smart terminal device may detect that the head is at the display position 3041 of the image 304 and the left hand is at the display position 3042 of the image 304. Then, the smart terminal device 302 may further determine that the left hand of the user 301 is located at a left position near the head height. Next, in response to determining that the head-left hand positional relationship satisfies a preset unlocking condition (for example, the left hand is located on the left side of the head by default, and the height difference is smaller than a preset threshold), the smart terminal device 302 may release the screen locking state 305. Optionally, the smart terminal device 302 may also play audio representing the release of the screen lock through the speaker 3023.
At present, one of the prior art generally adopts face recognition to unlock a screen, which leads to easy mistaken unlocking caused by detecting a remote face. One of the prior art may also adopt fingerprint identification, key or sliding unlocking, so that only the contact device can be unlocked. Gesture unlocking also can be adopted in the prior art, so that the accuracy of gesture recognition is low under the condition of a long distance. In the method provided by the embodiment of the disclosure, the mode switching (for example, unlocking) of the electronic device is performed according to the specific position relationship between different preset parts of the human body by acquiring the position relationship between the first preset body part and the second preset body part of the human body and matching the position relationship with the preset mode switching condition, so that the mode switching of the electronic device can be accurately and quickly performed at a longer distance, and the misoperation rate is effectively reduced. Furthermore, interaction is achieved by avoiding contact with the electronic device, reducing wear of the physical device.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for switching operating modes of an electronic device is shown. The process 400 of the method for switching the operation mode of the electronic device includes the following steps:
Step 401 and step 402 are respectively consistent with step 201 and step 202 in the foregoing embodiment and their optional implementation manners, and the above description on step 201 and step 202 and their optional implementation manners also applies to step 401 and step 402, which is not described herein again.
And 403, in response to the fact that the position relation meets the preset mode switching condition, acquiring a target number of associated images.
In the present embodiment, in response to determining that the positional relationship satisfies the preset mode switching condition, an execution subject of the method for switching the operation mode of the electronic apparatus (e.g., the terminal apparatus 101 shown in fig. 1) may acquire the target number of associated images in various ways. Wherein, the shooting time of the related image is usually related to the shooting time of the target image.
As an example, the execution subject may acquire the target number of associated images in a manner consistent with acquiring the target image. The target image may be a frame of a video captured by a camera of the electronic device. And video is essentially a sequence of images arranged in chronological order. The target number of associated images may be images selected from the image sequence. As an example, the number of images of the target adjacent to the shooting time of the target image can be selected according to the frame rate; or at preset intervals (e.g., every second).
In this embodiment, the executing body may first determine the number of images in which the positional relationship between the first preset body part and the second preset body part satisfying the preset mode switching condition is displayed in the target number of associated images acquired in step 403. Thereafter, the execution body may compare the determined number with the preset threshold. In response to determining that the determined number exceeds the preset threshold, the executing main body may switch the operating mode of the electronic device according to the indication of the preset mode switching condition in a manner consistent with the corresponding step in step 203 in the foregoing embodiment.
As an example, the execution subject may perform matching with a preset mode switching condition for each of the target number of associated images, and then determine the number of associated images that satisfy the preset mode switching condition. As another example, for example, the preset threshold is 3, and the executing body may not determine whether other associated images satisfy the preset mode switching condition after determining that there are 4 associated images satisfying the preset mode switching condition, so as to improve efficiency.
In some optional implementation manners of this embodiment, based on that the preset mode switching condition includes a preset position relationship condition and a preset hand form condition, the executing body may further determine that the preset mode switching condition is satisfied only when the preset position relationship condition and the preset hand form condition are satisfied at the same time.
As can be seen from fig. 4, the flow 400 of the method for switching the operation mode of the electronic device in the embodiment represents a step of acquiring a target number of associated images associated with shooting times, and a step of switching the operation mode of the electronic device according to a comparison between the number of images satisfying a condition in the determined associated images and a preset threshold. Therefore, the scheme described in this embodiment can compensate for the detection deviation that may occur in a single picture by detecting multiple pictures, thereby achieving the effect of reducing the occurrence rate of the error switching of the working mode of the electronic device.
