Referring to fig. 1, it is a flowchart of a first implementation procedure of a monitoring method based on an electronic device according to an embodiment of the present application, and for convenience of description, only a part related to the embodiment of the present application is shown.
First, one or more embodiments of the present specification provide an electronic device based monitoring method.
The method of this embodiment may be executed by any single electronic device having a multimedia display function and a data processing function, that is, each step included in the method of this embodiment may be executed by the same electronic device. In addition, the method of the embodiment can also be completed by mutually matching a plurality of electronic devices. In such a distributed scenario, one of the devices may perform only one or more steps of the method of one or more embodiments of the present disclosure, and the devices may interact with each other to complete the method.
As an optional application scenario, the electronic device is a student terminal with an electronic textbook and a teaching interaction function, and a user of the electronic device is a student. When the monitoring method is implemented by a single electronic device, the monitoring method based on the electronic device is executed by the student terminal. When the interactive implementation is carried out through a plurality of electronic devices, besides the student terminals, the interactive implementation also comprises a teacher terminal used for controlling the student terminals, and users of the teacher terminal are teachers, and can carry out data interaction with the student terminals through the teacher terminal and control the student terminals; correspondingly, the using prompting method of the electronic equipment comprises the step that the student terminal and the teacher terminal respectively execute partial steps. In the following embodiments, the application scenarios related to the teaching are all described as examples. It can be understood that the application scenario related to the teaching is not limited to the application scenario of the method of this embodiment, and based on the content and effect of the present disclosure, a person skilled in the art may apply the technical solution of the present disclosure to any other suitable application scenario, such as a scenario where a user works through a PC, or a scenario where a user uses a mobile phone daily.
A preferred embodiment of the present disclosure may be that, the monitoring method based on the electronic device includes:
and S101, acquiring at least two pieces of distance information of the face of the user from the electronic equipment according to a preset time interval.
In this embodiment, the electronic device performs at least two consecutive detections to obtain at least two pieces of distance information reflecting a distance from the face of the user to the electronic device, where the at least two pieces of distance information are used to jointly determine a usage state of the electronic device by the user in a subsequent step.
Wherein the detection is performed at least twice consecutively based on a predetermined time interval. The time intervals may be equal and flexibly set according to specific needs, such as 5 seconds, 10 seconds, 30 seconds, etc. In addition, the time intervals may also be set to be unequal; the time interval between two adjacent detections gradually decreases as the number of detections increases; alternatively, different time intervals may be set according to different time periods, for example, in the morning, when students are energetic, a relatively long time interval may be set, for example, 20 seconds, and in the afternoon, when students are apt to be tired and to be distracted from controlling the distance from the face to the student terminal, a relatively short time interval may be set, for example, 10 seconds.
In some possibly implemented embodiments, the obtaining at least two pieces of distance information of the face of the user from the electronic device according to a preset time interval specifically includes:
s201: and acquiring the frequency variation of an alternating magnetic field between the electronic equipment and the face of the user according to a preset time interval, wherein the alternating magnetic field is a magnetic field generated by the electronic equipment.
As can be seen from the related electromagnetic field principle, when a person or other conductor approaches an alternating magnetic field generated by an oscillating circuit with an inductance diagram, an induced current (eddy current) is generated on the surface of a human body, and the induced current generates a reverse magnetic field to hinder a magnetic field generated by the inductance, so that the equivalent impedance of a load is lowered, the voltage of the load is lowered, and the generated frequency is lowered. The induced current is related to the resistivity of the measured object, the permeability of the measured object, the distance of the measured object from the coil, and the frequency of the current through the coil. When the resistivity of the object to be measured, the permeability of the object to be measured and the frequency of the current passing through the coil are all unchanged, the induced current is only related to the distance between the object to be measured and the coil, and the load voltage variation and the frequency variation are functions related to the distance between the object to be measured and the coil.
S202: and acquiring the at least two pieces of distance information through the frequency variation.
Wherein, based on the above principle, an oscillation circuit with an inductance diagram is provided on the electronic device to generate an alternating magnetic field in the vicinity of the electronic device, and a frequency change of the alternating magnetic field is continuously detected by a detection device at predetermined time intervals to obtain at least two frequency change amounts; and for each frequency variation, calculating the distance information according to a preset functional relation after amplifying and filtering the frequency variation. Similarly, the variation of the load voltage in the oscillating circuit may be detected, and the distance information may be calculated according to a preset functional relationship.
In some other possibly implemented embodiments, the obtaining at least two pieces of distance information of the face of the user from the electronic device according to the preset time interval specifically includes:
acquiring at least two detection images according to a preset time interval, wherein the at least two detection images comprise face images of the user;
and acquiring the at least two pieces of distance information according to the ratio of the face image of the user to the detection image.
The detection image comprising the face image of the student is collected through a camera which is carried by the student terminal or is installed outside the student terminal. Under the image acquisition mode, when the face of the student is close to the student terminal, the area percentage occupied by the face image of the student in the detection image is larger; when the face of the student is far away from the student terminal, the area percentage occupied by the face image of the student in the detection image is smaller. That is, the area percentage of the student face image in the detection image has a certain functional relationship with the distance from the student face to the student terminal; the functional relation can be summarized through using data of a large number of students to the student terminals. Furthermore, the area percentage of the student face image in each detection image is determined according to at least two detection images acquired at a preset time interval, and the distance information can be calculated according to the obtained functional relation.
Of course, the distance information may be obtained in other ways than the two embodiments described above. The distance information, such as by way of infrared ranging; or the distance information is obtained by collecting images including student terminals used by students and analyzing and processing the images in an artificial intelligence mode.
It should be noted that, an existing face image set may be used to perform corresponding preprocessing, in an embodiment of the present invention, taking WIDER FACE data set as an example, a WIDER FACE data set is a benchmark data set for face detection, and includes 32203 images and 393703 annotated faces, where 158989 annotated faces are located in a training set, and 39496 annotated faces are located in a verification set. Each subset contains 3 levels of detection difficulty: easy, Medium, Hard. The FACEs have a large variation range in scale, posture, illumination, expression and occlusion, WIDER FACE selected images mainly come from a public data set WIDER, WIDER FACE is divided into 61 categories, and 40%, 10% and 50% of each category are randomly selected as training, verification and test sets.
In addition, the WIDER FACE data set was preprocessed: the pretreatment comprises the following steps: and carrying out random cutting, color disturbance, random overturning and scaling to a fixed size on the original image in the data set. Selecting a random proportion for the shortest side in the image, and randomly cutting a square area in the image according to the length; randomly adjusting the contrast and saturation of the image obtained after the clipping in the range of (0.5-1.5); then, randomly overturning the image; and the processed images are uniformly scaled to 640 multiplied by 640, so that the subsequent training in the convolutional neural network is facilitated.
S102: marking the at least two pieces of distance information as regular distance information or irregular distance information through a preset marking rule, wherein the marking rule is a preset marking formula, and the marking formula is as follows:
said
For the converted value, f is a mark constant,
for the ith sample of range information,
the j-th central point corresponding to the i-th distance information sample when the conversion value is
Above a threshold value X, the distance is marked as irregular distance information, the conversion value
And when the distance is smaller than or equal to the threshold value X, marking as the conventional distance information.
In this embodiment, at least two pieces of distance information obtained in the foregoing steps are respectively corresponding to a normal state or an abnormal state. It should be noted that the classification and labeling of the distance information are performed according to the distance information and a preconfigured labeling rule, and the preconfigured labeling rule may be a commonly used algorithm model.
In some possibly implemented embodiments, the marking, by a pre-configured marking rule, the at least two pieces of distance information as regular distance information or irregular distance information specifically includes:
judging whether the distance information falls into a preset threshold interval or not;
if so, marking the distance information as irregular distance information;
and if not, marking the distance information as the conventional distance information.
In this embodiment, the threshold interval may be preset according to a distance that should be maintained under a normal condition without significantly affecting the eyesight when the user uses the electronic device. The threshold interval can be set correspondingly according to the size of the electronic equipment; in general, if the student terminal is a handheld device or a desktop PC, the threshold interval may be set to 0-30 cm; in other application scenarios, when the electronic device is large in size, such as a large display screen and an electronic whiteboard, the threshold interval may be set to 0-150 cm. The endpoint values specifically related to the threshold interval are only examples, and can be flexibly set according to implementation needs in a specific implementation process.
The preconfigured marking rule is a preconfigured statistical model, the statistical model is a preconfigured model that can detect whether each piece of position information included in the time series is abnormal through a set statistical determination method, and the statistical determination method in this embodiment may be various determination methods based on a statistical analysis principle, such as a normal distribution method based on a 3sigma principle, and Tukey's test based on graph-based detection. The unsupervised learning model is a pre-constructed model capable of detecting whether distance information included in at least two pieces of distance information is abnormal or not through a set unsupervised learning method, and the unsupervised learning method judges whether the distance information is abnormal or not through exciting a behavior with a correct detection result. The marking rule is not further limited in the scheme, and the marking rule can be a general type in the market.
It should be noted that, when the electronic device acquires the distance information, the distance information is input to the statistical model for classification and marking, and whether the distance information falls into a preset threshold interval is determined; if so, marking the distance information as irregular distance information; and if not, marking the distance information as the conventional distance information.
In addition, the distance information is compared with a threshold interval, if the distance information falls into the threshold interval, the distance information is corresponding to unconventional distance information, and the fact that the distance between the face of the student and the student terminal is short at the detection time corresponding to the distance information is shown, and the distance information possibly needs to be prompted; and if the distance information does not fall into the threshold interval, the distance information is corresponding to the conventional distance information, and the fact that the distance between the face of the student and the student terminal is normal at the moment of detection corresponding to the distance information is shown without prompting.
S103: and if the irregular distance information of the first quantity is continuously generated, generating a first monitoring result, wherein the first monitoring result is used for controlling the electronic equipment to enter an alarm state.
In some possible implementations, the determination of whether a prompt is needed is based on irregular distance information. Specifically, when the distance information temporarily corresponds to the irregular distance information, it indicates that the face of the user is closer to the electronic device at the detection time corresponding to the distance information, but may not need to be prompted immediately. This is because the student only carelessly lowers his head or temporarily approaches the student terminal to watch the contents carefully, and the student does not maintain the above-described posture but restores the normal posture for a short time.
In view of the above situation, in this step, statistics is performed on states corresponding to a plurality of consecutive distance information, and a prompt is given when a first number of consecutive irregular distance information is obtained. The distance information is continuously acquired at preset time intervals, if the first preset number of continuous distance information corresponds to irregular distance information, it is indicated that the user is always in a state that the distance from the face to the electronic equipment is short within a continuous period of time, and it is determined that prompt needs to be performed on the user at the moment, and a first monitoring result is generated.
In some possible embodiments, the number of the threshold intervals is at least two, and at least two of the threshold intervals respectively correspond to different warning states;
if the irregular distance information of the first number is continuously generated, a first monitoring result is generated, wherein the first monitoring result is used for controlling the electronic device to enter the warning state, and the method specifically includes:
determining the threshold interval into which the last distance information in time sequence falls when a first number of irregular distance information is continuously generated;
and determining the warning state according to the threshold interval in which the last distance information falls in the time sequence.
At least two threshold intervals are arranged, and different threshold intervals correspond to different distances from the face of the student to the student terminal. That is, in this embodiment, under the nearer condition of distance of student's face to student's terminal, further consider different proximity, to the corresponding different suggestion strategies that set up of different proximity, and then realize according to different proximity, carry out the technological effect of the suggestion of degree.
In some other possible embodiments, at least two of the threshold intervals include: a first threshold interval, a second threshold interval and a third threshold interval; the numerical values contained in the first threshold interval, the second threshold interval and the third threshold interval are continuously and sequentially reduced;
the warning state corresponding to the first threshold interval is as follows: displaying prompt information;
the warning state corresponding to the second threshold interval is as follows: sending out a prompt tone;
the warning state corresponding to the third threshold interval is as follows: and displaying the prompt information and sending a prompt tone.
In some other possible implementations, in case that the first amount of irregular distance information is continuously generated, generating a first monitoring result, where the first monitoring result is used to control the electronic device to enter an alert state, the method further includes:
if a second amount of irregular distance information is continuously generated, controlling the electronic equipment to reduce the brightness;
and if the third amount of irregular distance information is continuously generated, controlling the electronic equipment to screen-turn.
Compared with the prior art, the implementation mode of the invention has the following beneficial effects: firstly, acquiring at least two pieces of distance information of a face of a user from the electronic equipment according to a preset time interval, and then marking the at least two pieces of distance information as regular distance information or irregular distance information according to a preset marking rule, wherein the marking rule is a preset marking formula:
