Detailed Description
Technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present disclosure, belong to the protection scope of the embodiments of the present disclosure.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for determining a mobile terminal drop-out in an embodiment of the present disclosure is shown, which is described in detail as follows.
And step 101, responding to the detection of at least one person by the camera, detecting the physical address of the mobile terminal and the short-distance wireless signal strength, and obtaining the physical address and the first signal strength of the mobile terminal.
The embodiment of the disclosure is used for extracting the person information from the real-time image shot by the camera and judging whether the persons leave all the persons, so that whether the mobile terminal is left or not is determined by combining the short-distance wireless signal strength of the mobile terminal under the condition that the persons leave all the persons. The camera is pre-installed and used for shooting a preset area, and the preset area is an area where people stay. For example, a dining table area when the user goes out for a meal, a meeting area when the employee is in a meeting, and the like.
Wherein, the short-range wireless signal strength is the signal strength of the short-range wireless communication, the mobile terminal can be used as a signal source for transmitting the short-range wireless signal, and the short-range wireless signal can include but is not limited to: bluetooth signals, Wi-Fi signals, zigbee signals.
Specifically, the camera determines that a person is detected when recognizing face information from a captured image. In practical application, a processor built in the intelligent camera can be used for recognizing the face information, and the image can also be sent to a processor arranged outside for recognizing the face information.
Taking Wi-Fi signals as an example, when the mobile terminal starts a Wi-Fi function, the mobile terminal may continuously send Wi-Fi data packets to detect a Wi-Fi device for connection, where the data packets carry various information of the mobile terminal, such as a physical address. The embodiment of the disclosure can receive Wi-Fi data packets through a Wi-Fi probe or other devices capable of receiving the Wi-Fi data packets, extract physical addresses from the Wi-Fi data packets, and determine the strength of received Wi-Fi signals; of course, for the bluetooth signal, the mobile terminal continuously sends a bluetooth data packet to detect the connectable bluetooth device when the bluetooth function is turned on, wherein the data packet carries various information of the mobile terminal, such as a physical address. Embodiments of the present disclosure may receive a bluetooth packet via a bluetooth probe or other devices that may receive the bluetooth packet, extract a physical address therefrom, and determine a received bluetooth signal strength
And 102, responding to the fact that the camera detects that each person leaves, and detecting the short-distance wireless signal intensity of the mobile terminal in real time based on the physical address of the mobile terminal to obtain a second signal intensity.
The camera can continuously shoot images at certain time intervals, people are identified from the shot images, if no people exist in the images, the people are determined to leave, and whether the mobile terminal is left or not needs to be determined at the moment; otherwise, if at least one person exists in the image, whether the mobile terminal is left or not is uncertain.
It will be appreciated that the physical address of the mobile terminal may serve as a unique identifier for the mobile terminal, so that different mobile terminals may be distinguished according to the physical address to track the mobile terminal detected in step 101 without concern for the remaining mobile terminals.
And 103, determining whether the mobile terminal is left according to the first signal strength and the second signal strength.
It can be understood that, since the detection device for the short-distance wireless signal is fixed, if the position of the mobile terminal is changed, the first signal strength and the second signal strength are different, and it can be determined that the mobile terminal is not left; if the position of the mobile terminal is not changed, the first signal strength and the second signal strength are close to or the same, and at this time, the mobile terminal can be determined to be left.
In the embodiment of the disclosure, the camera, the detection device for the short-distance wireless signal strength and the mobile terminal form a system, and in addition, a processor can be further arranged, wherein both the camera and the detection device can be communicated with the processor, the camera sends the shot image to the processor for analysis, the detection device sends the detected short-distance wireless signal strength to the processor for analysis, so that the processor can analyze whether the person leaves or not from the image and determine whether the mobile terminal is left or not by combining the short-distance wireless signal strength. The processor is also used for controlling the camera to start shooting and end shooting, and controlling the detection device to start detection and end detection, and the like.
In summary, an embodiment of the present disclosure provides a method for determining a mobile terminal being left, where the method includes: responding to the detection of at least one person by the camera, detecting the physical address of the mobile terminal and the short-distance wireless signal strength, and obtaining the physical address and the first signal strength of the mobile terminal; responding to the fact that the camera detects that each person leaves, and detecting the short-distance wireless signal intensity of the mobile terminal in real time based on the physical address of the mobile terminal to obtain a second signal intensity; and determining whether the mobile terminal is left according to the first signal strength and the second signal strength. The embodiment of the disclosure can combine the short-distance wireless signal strength and the character behaviors to accurately determine whether the mobile terminal is left or not, and does not need a user to perform additional operation, so that the operation complexity is low.
Example two
Referring to fig. 2, a flowchart illustrating specific steps of a method for determining a mobile terminal drop-out in another embodiment of the present disclosure is shown, specifically as follows.
This step can refer to the detailed description of step 101, and is not described herein again.
Step 202, the camera detects whether each person in the captured image has a departure behavior through a departure behavior detection model obtained through pre-training, the departure behavior detection model is obtained through training of an image sample set, and the image sample set includes: the positive examples of leaving behavior are noted as well as the negative examples where there is no leaving behavior.
Wherein the departure behavior detection model may include: and the convolution operation unit can perform convolution operation on the pixels in the image so as to learn the pixel characteristics of the departure behavior in the training process, so that the departure behavior detection model obtained through training can detect the departure behavior from the image.
It will be appreciated that the departure behaviour detection model may be selected from commonly used deep learning models, for example, convolutional neural network models.
Step 203, responding to the fact that the camera detects that each person has a departure behavior, or the number of the persons detected by the camera is 0, detecting the short-distance wireless signal strength of the mobile terminal in real time based on the physical address of the mobile terminal, and obtaining a second signal strength.
The number of the persons detected by the camera is 0, the persons are all separated, each person has a separating action and indicates that all persons are ready to separate, and therefore whether the mobile terminal is left or not can be determined timely at two moments of preparing to separate and separating.
Specifically, when the camera cannot detect face information from the captured image, it is determined that the number of persons is 0.
It is understood that if there is no departure behavior for one of the persons, the person being about to depart may be temporarily departing, and it is not necessary to determine whether the mobile terminal is left based on the short-range wireless signal strength of the mobile terminal.
After obtaining the first signal strength and the second signal strength, it can be determined that the mobile terminal is left by the methods of steps 204 to 205 or 206, respectively, or the two methods can be combined.
And 204, calculating the position of the mobile terminal according to the first signal strength and the second signal strength respectively to obtain a first position and a second position.
It can be understood that the detected short-range wireless signal strength is related to the distance between the mobile terminal sending the short-range communication data packet and the detection device (such as Wi-Fi probe and bluetooth probe) of the short-range wireless signal strength, and the larger the distance between the mobile terminal and the detection device is, the smaller the detected short-range wireless signal strength is; the smaller the distance between the mobile terminal and the detection device is, the greater the detected short-distance wireless signal strength is. So that the position of the mobile terminal can be determined according to the short-range wireless signal strength when the position of the detection device is unchanged.
Specifically, the positions of the detection devices may be used as reference positions, short-range wireless signal intensities corresponding to a plurality of positions may be counted in advance, short-range wireless signal intensity attenuation amounts corresponding to unit distances may be calculated according to the short-range wireless signal intensities between different positions, and a function model between the short-range wireless signal intensity and the positions may be established according to the short-range wireless signal intensity attenuation amounts, so that the first signal intensity and the second signal intensity may be input to the function model, respectively, to obtain the first position and the second position.
Step 205, in response to that the distance between the first location and the second location is greater than or equal to a preset distance threshold, determining that the mobile terminal is not left.
The preset distance threshold may be set according to an actual application scenario, and is not limited by the embodiment of the disclosure.
It can be understood that the position may directly represent whether the mobile terminal is in a preset area, and if the preset area is a dining table, when the mobile terminal is located on the dining table after the user takes a seat, the first position of the mobile terminal is obtained; when or after people on the dining table leave, if the distance between the second position and the first position is larger than or equal to a preset distance threshold value, determining that the mobile terminal is not on the dining table and the mobile terminal is not left; and if the distance between the second position and the first position is smaller than a preset distance threshold value, determining that the mobile terminal is still on the dining table and the mobile terminal is left.
And step 206, in response to that the difference value between the first signal strength and the second signal strength is greater than or equal to a preset signal difference threshold value, determining that the mobile terminal is not left.
The signal difference threshold may be set according to an actual application scenario, and is not limited by the embodiments of the present disclosure.
It is to be understood that the first signal strength is used as a reference signal strength, for example, when the user sits on a dining table while dining, the mobile terminal is placed on the dining table, so that the first signal strength of the mobile terminal can be used to determine whether the mobile terminal is still on the dining table at this time, because the short-distance wireless signal strength will be different from the first signal strength after the mobile terminal leaves the dining table, and the farther away from the dining table, the larger the difference between the short-distance wireless signal strength and the first signal strength is. Based on the principle, when or after people leave the dining table, if the difference value of the first signal strength and the second signal strength is smaller than a preset signal difference threshold value, the mobile terminal is still on the dining table and is left; and if the difference value of the first signal strength and the second signal strength is greater than or equal to the preset signal difference threshold value, determining that the mobile terminal is not on the dining table, and determining that the mobile terminal is not left.
In summary, based on the first embodiment, the embodiments of the present disclosure provide another method for determining a mobile terminal being left, which, in addition to the beneficial effects of the first embodiment, can also determine whether the mobile terminal is left or not by using multiple angles, such as distance and signal strength; the leaving behavior can be detected through a leaving behavior detection model so as to reduce the time delay for determining whether the mobile terminal is left; whether the mobile terminal is left can be further determined after people leave, and the risk of being left is further reduced.
