It can be seen that, in the embodiment of the present application, when the mobile terminal detects a location query request of a user for a wireless headset, the radar sensor is firstly enabled, then at least one target object in an area where the mobile terminal is located is scanned by the radar sensor, a profile image of each target object is obtained, then, a reference image of the wireless headset is compared with the profile image of each target object, a profile image matched with the reference image is obtained, and finally, location information of the wireless headset is determined according to the matched profile image. Therefore, the mobile terminal can scan surrounding objects through the radar sensor to obtain the outline image of the objects, the position of the wireless earphone is accurately identified through image comparison, and compared with the scheme that the position of the mobile terminal is used by a user for the last time through the existing intelligent offline recording, the actual position of the wireless earphone can be detected in real time, errors caused by recording the position of the mobile terminal and the situation that the position of the wireless earphone is moved but not correspondingly updated in an offline state are avoided, and the accuracy and convenience for positioning the position of the wireless earphone by the mobile terminal are improved.

the processor 120 is further configured to determine a volume of each target object according to the first contour image of each target object; the wireless earphone is used for screening at least one target object with the volume smaller than or equal to a preset volume from the plurality of target objects, wherein the preset volume is larger than the volume of the wireless earphone;
in the aspect of scanning at least one target object in the area where the mobile terminal 100 is located to obtain the profile image of each target object, the radar sensor 130 is specifically configured to scan the at least one target object according to a second scanning period to obtain the profile image of each target object, where the first scanning period is smaller than the second scanning period.
Wherein, when the radar sensor scans the surrounding objects, the scanning can be performed according to the preset direction (such as counterclockwise or clockwise, without unique limitation), the line and the plane are combined with the attached drawings to describe the process of scanning and detecting the outline of the target object in detail, as shown in fig. 1B, when the mobile terminal controls the radar sensor to scan a target object, the mobile terminal can detect the intensity of the echo signal in real time, in the first stage, after the transmitting direction of the transmitting signal is transferred from the peripheral area of the target object to the first edge outline of the target object, because the echo reflection distance changes greatly, the intensity of the echo signal of the corresponding radar sensor changes greatly, the mobile terminal can determine the outline of the target object corresponding to the transmitting direction after detecting the change, in the second stage, the transmitting signal of the radar sensor is continuously transmitted to the body of the target object and forms the echo signal, the echo signal intensity at the stage is mainly changed by the shape of the target object, the change interval of the echo signal intensity is relatively small, in the third stage, the transmitting direction of the transmitting signal is transferred to a peripheral area from the second edge profile of the target object, the echo reflection distance is greatly changed, the echo signal intensity of the corresponding radar sensor can be greatly changed, and through the detection process, the mobile terminal can identify the profile of the target object.
The first scanning period corresponds to a low-precision mode, and the second scanning period corresponds to a high-precision mode.
Therefore, in this example, the mobile terminal may first obtain the contour image of the object in the peripheral area in the low-precision mode, and predict the volume of the corresponding object, so as to screen out at least one target object that is close to the volume of the wireless headset, and further accurately determine the contour of the screened object in the high-precision mode, thereby facilitating to quickly and accurately position the contour of the wireless headset.

The position parameters comprise distance parameters and angle parameters, the distance from the target object to the radar sensor can be obtained by measuring the time difference between a transmitting signal and an echo signal reflected by the target object, dividing the time difference by 2 and multiplying the time difference by the light speed, the angle information is the direction from which the target object comes relative to the radar sensor, the angle information mainly comprises an elevation angle and an azimuth angle, the direction is realized through the directivity of an antenna of the radar sensor, a beam transmitted by the radar sensor is narrow and narrow like a light column of a searchlight, the directivity is strong, the direction is observed in which direction an echo without a target exists, the direction is not changed, the angle is recorded in some directions, the distance information and the angle information of the target object relative to the radar sensor exist, the position of the target object relative to the radar can be known, and the positioning is realized.
Therefore, in this example, the mobile terminal can accurately calculate the actual position of the wireless headset according to the position parameters when the wireless headset is scanned, so that the positioning accuracy is improved.
In one possible example, the processor 120, after said determining the location information of the wireless headset from the matched scan image, is further configured to: generating a navigation route according to the position information; and for navigating according to the navigation route.
The navigation route may be a navigation route based on an indoor map navigation technology, and specifically, an initial position of a current mobile terminal and a target position of a wireless headset may be presented on an indoor map, and an optimal route from the initial position to the target position is planned.
Therefore, in this example, after the mobile terminal locates the position of the wireless headset, the navigation route can be further provided, so that the user can find the wireless headset in time according to the navigation route, and convenience and intelligence of inquiring the wireless headset are improved.
In one possible example, the processor 120 is further configured to: determining that the wireless earphone is in an effective connection distance range according to the position information of the wireless earphone, and establishing wireless connection with the wireless earphone; and the wireless earphone is used for controlling the wireless earphone to play preset audio information at the maximum volume so as to prompt the user of the position.
The preset audio can enable the sound which is easy to attract the attention of the user to be played, and specifically, the preset audio can be preset by a developer or preset by the user.
Therefore, in the example, after the position of the wireless earphone is determined, the mobile terminal can further perform position reminding by controlling the wireless earphone to play specific sound, so that the implementation mode of determining the position of the wireless earphone through the mobile terminal is further expanded, and the searching convenience and diversity are improved.
