Please refer to FIG. 2 , which is a schematic flowchart of a height measurement method in an embodiment. As shown in Figure 2, the height measurement method comprises the following steps:

Step S101, when the electronic device enters the height measurement mode, collect the horizontal distance of the electronic device relative to the measured object through the distance collection device when receiving a user's measurement start instruction or after a preset time.

In a specific implementation, the distance measurement data stored in the distance acquisition device in the electronic device can be cleared according to the calibration instruction, and the angle acquisition device can be calibrated, and the current position of the electronic device can be As the standard zero-distance position, that is, as the starting point position of the horizontal distance _h1 .

When the user's click operation on the virtual button or the central area is received, it is determined that the horizontal movement of the electronic device is completed. At this time, the distance between the current position and the standard zero-distance position is calculated to obtain the horizontal distance h ₁ .

In another specific implementation, the virtual key may not be set. After entering the height measurement mode, the electronic device is timed by a timer, and when the preset time is reached, such as 20 seconds, it is determined that the horizontal movement of the electronic device is completed, and the current position and the standard zero distance are calculated at this time The distance between the positions, that is, the horizontal distance h ₁ is obtained. In this way, the calculation of the horizontal distance h ₁ can also be completed without receiving a manual operation from the user. Please refer to FIG. 3 , which shows a schematic diagram of the horizontal distance and rotation angle collected in the height measurement method.

Step S103, according to the collected horizontal distance h ₁ and the first rotation angle θ ₁ , and the second rotation angle θ ₂ , calculate the user's height in a predetermined calculation manner.

In a specific implementation, the predetermined calculation method may be:

User's height=horizontal distance×[the tangent of the first rotation angle+the tangent of the difference between the second rotation angle and the first rotation angle]

The purpose of clearing all the data on the electronic device is to prevent the previously stored measurement data from being confused in the current measurement process. The purpose of calibrating the collection device is to make the data collected by the collection device more accurate, and to calibrate the sensitivity of the distance and angle collection device. In this embodiment, the preset area is the central area of the touch screen.

The fourth step is to calculate the rotation angle between the standard line and the horizontal line when the standard line is tangent to the user's foot. When the standard line is tangent to the user's foot, the angle of the rotation angle between the standard line and the horizontal line = the second rotation angle θ ₂ - the first rotation angle θ ₁ , and the The second rotation angle θ ₂ is saved.

S4, when it is sensed that the electronic device obtains the second rotation angle θ ₂ , according to the collected horizontal distance h ₁ and the first rotation angle θ ₁ , the second rotation angle θ ₂ is calculated in a predetermined calculation manner. height. The predetermined calculation method is:

User's height=horizontal distance×[the tangent of the first rotation angle+the tangent of the difference between the second rotation angle and the first rotation angle]

The corresponding calculation formula is:

h _height = h ₁ [tanθ ₁ +tan(θ ₂ -θ ₁ )]

The operation of the included rotation angle generated when the user performs the rotation operation is detected by the angle acquisition device, and the included rotation angle is recorded as the second included rotation angle θ ₂ . The memory 32 connected to the distance acquisition device 311 and the gyroscope 312 is used to store the electronic device at the horizontal distance h ₁ , the first rotation angle θ ₁ , and the second rotation angle θ ₂ .

The processor 33 connected with the collection device 31 and the memory 32 is used for clearing the distance measurement data stored in the distance collection device 311 in the electronic device when the electronic device enters the height measurement mode and converting the The angle acquisition device performs calibration processing, and uses the current position of the electronic device as a standard zero-distance position. The purpose of clearing all the data on the electronic device is to prevent the previously stored measurement data from being confused in the current measurement process. The purpose of calibrating the collection device is to make the data collected by the collection device more accurate and to calibrate the sensitivity of the collection device.

And the processor 33 is further configured to calculate the user's height in a predetermined calculation manner according to the collected horizontal distance h ₁ , the first rotation angle θ ₁ , and the second rotation angle θ ₂ . The predetermined calculation method pre-stored in the processor 33 is:

User's height=the horizontal distance×[the tangent of the first rotation angle+the tangent of the difference between the second rotation angle and the first rotation angle]

The corresponding calculation formula is:

h _height = h ₁ [tanθ ₁ +tan(θ ₂ -θ ₁ )]

The display 34 connected with the processor 33 is used for displaying the calculated height of the user so as to give feedback to the user so as to know his own height data. In this embodiment, the display 34 is the touch screen of the smart phone in this embodiment. The touch display screen provides both an output interface and an input interface between the device and the user. The touch display controller receives/sends electrical signals from/to the touch display. The touch display then displays visual output to the user. This visual output can include text, graphics, video, and any combination thereof. Some or all of the visual output may correspond to user interface objects, more details of which are described below.

Touch displays also accept user input based on tactile and/or tactile contact. The touch display screen forms a touch-sensitive surface that accepts user input. The touch display and touch display controller (along with any associated modules and/or instruction sets in memory) detect contact (and any movement or interruption of said touch) on the touch display and convert the detected Contacts translate into interactions with user interface objects, such as one or more soft keys, displayed on the touch display. In one exemplary embodiment, the point of contact between the touch display screen and the user corresponds to one or more fingers of the user. The touch display may use LCD (Liquid Crystal Display) technology or LPD (Light Emitting Polymer Display) technology, although in other embodiments other display technologies may be used. Touch displays and touch display controllers can detect contact and its movement or interruption using any of a variety of touch-sensitive technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, and Other proximity sensor arrays, or other techniques for determining one or more points of contact with a touch display. A user may use any suitable object or accessory, such as a stylus, finger, etc., to contact the touch display.
