Wherein, Figure 3The flowchart shown can be applicable to Figure 1A The scenario diagram shown, Figure 3 The measurement method shown can include the following steps:

[0079] 301. The terminal device sends a first control instruction to the first electronic device.

[0080] 302. The first electronic device, upon receiving the first control instruction, transmits a first signal through a first UWB module.

[0081] In some embodiments, the first electronic device can pre-establish a Bluetooth connection with the terminal device. The terminal device can send a first data packet carrying the first control instruction to the first electronic device through the Bluetooth module of the terminal device. The first electronic device can receive the first data packet through the Bluetooth module of the first electronic device, and parse the first data packet to extract the first control instruction from the first data packet, and respond to the first control instruction to transmit the first signal through the first UWB module.

[0082] 303. The terminal device sends a second control instruction to the second electronic device.

[0083] 304. The second electronic device, upon receiving the second control instruction, receives the first signal through a second UWB module, and obtains a first flight time between the second UWB module and the first UWB module according to the first signal.

[0084] Similarly, the second electronic device can pre-establish a Bluetooth connection with the terminal device. The terminal device can send a second data packet carrying the second control instruction to the second electronic device through the Bluetooth module of the terminal device. The second electronic device can receive the second data packet through the Bluetooth module of the second electronic device, and parse the second data packet to extract the second control instruction from the second data packet, and respond to the second control instruction to receive the first signal transmitted by the first electronic device through the second UWB module.

[0085] 305. The second electronic device sends the first flight time to the terminal device.

[0086] In some embodiments, the second electronic device can send the first flight time to the terminal device through the Bluetooth module of the second electronic device. It should be noted that the sending method of the first flight time is the same as the sending method of the first control instruction and the second control instruction, and the embodiments of the present application will not be repeated.

[0087] 306. The terminal device, upon receiving the first flight time, determines a first measurement result according to the first flight time.

[0088] The first flight time represents a time required from the first UWB module transmitting the first signal to receiving the return signal of the first signal by the second UWB module.

[0089] In a case where the first measurement result includes a distance value between the measurement start point and the measurement end point, the terminal device determining the first measurement result according to the first flight time can include: the terminal device obtaining half of the first flight time, and multiplying the half of the first flight time by a signal propagation speed to obtain the distance value between the measurement start point and the measurement end point.

[0090] In a case where the first measurement result includes parameter information of a target circle passing through the measurement start point and the measurement end point, the terminal device determining the first measurement result according to the first flight time can include: the terminal device obtaining a distance value between the measurement start point and the measurement end point according to the first flight time; taking the distance value as a diameter of the target circle passing through the measurement start point and the measurement end point; and obtaining the parameter information of the target circle according to the diameter of the target circle.

[0091] The distance value between the measurement start point and the measurement end point can be obtained in the manner described above, which will not be described herein again. The parameter information of the target circle can be obtained according to the diameter of the target circle, which can include: obtaining a radius of the target circle according to the diameter of the target circle, and obtaining the parameter information of the target circle according to the radius and a first relationship. The first relationship can include a circumference formula and / or an area formula.

[0092] In a case where the first measurement result includes the distance value between the measurement start point and the measurement end point, and / or the parameter information of the target circle passing through the measurement start point and the measurement end point, the first UWB module and the second UWB module can each include an antenna for receiving / transmitting a wireless signal.

[0093] In a case where the first measurement result includes a relative angle between the measurement start point and the measurement end point, the second UWB module includes a first antenna array, and the first flight time includes a flight time between each antenna in the first antenna array and the first UWB module.

[0094] Further, the terminal device determining the first measurement result according to the first flight time can include: obtaining a first target phase difference between a first antenna and a second antenna of the first antenna array according to respective flight times of the first antenna and the second antenna in the first flight time, and obtaining the relative angle between the measurement start point and the measurement end point according to the first target phase difference, where the first antenna and the second antenna are any two antennas of the first antenna array. It can be understood that the first antenna array can include at least two antennas.

[0095] The first target phase difference is obtained by subtracting the flight time corresponding to the second antenna from the flight time corresponding to the first antenna. It should be noted that the first target phase difference is greater than 0. Further, obtaining the relative angle of the measurement start point and the measurement end point according to the first target phase difference can include: obtaining a first distance difference value according to the first target phase difference, the first distance difference value representing the difference between the distance value between the first antenna and the first UWB module and the distance value between the second antenna and the first UWB module; and obtaining the relative angle of the measurement start point and the measurement end point according to the first distance difference value, a first interval distance value, and a preset angle calculation formula, the first interval distance value indicating the distance between the first antenna and the second antenna of the first antenna array. The first distance difference value can be obtained by multiplying the first target phase difference by the signal propagation speed.

[0096] In the embodiments of the present application, the angle calculation formula can be represented as: θ = arccos (d1 / d2), where d1 represents the first distance difference value, d2 represents the first interval distance value, and θ represents the relative angle of the measurement start point and the measurement end point.

[0097] By implementing the above method, the second electronic device first receives the first signal transmitted by the first electronic device, and obtains the first flight time of the first electronic device and the second electronic device according to the first signal, and then transmits the first flight time to the terminal device, so that the terminal device determines the first measurement result according to the first flight time. The first flight time obtained by the terminal device is directly transmitted by the second electronic device, and therefore, in this measurement method, the terminal device does not need to participate in the analysis of the UWB signal, which greatly reduces the device power consumption of the terminal device.

[0098] Please refer to Figure 4 , Figure 4 is a flowchart of another measurement method disclosed in the embodiments of the present application. Figure 4 The flowchart shown in the figure can be applied to Figure 1B The scene diagram shown in the figure, such as Figure 4 The measurement method shown in the figure can include the following steps:

[0109] In some embodiments, the terminal device determines the first measurement result according to the second flight time and the third flight time can include: the terminal device obtains a second target phase difference between the third antenna and the fourth antenna according to the corresponding flight time of the third antenna and the fourth antenna in the second flight time, and obtains first relative position information of the terminal device and the first electronic device according to the second target phase difference; the third antenna and the fourth antenna are any two antennas of the second antenna array; obtains a third target phase difference between the third antenna and the fourth antenna according to the corresponding flight time of the third antenna and the fourth antenna in the third flight time, and obtains second relative position information of the terminal device and the second electronic device according to the third target phase difference; and obtains the first measurement result according to the first relative position information and the second relative position information.

It can be understood that in the preset angle calculation formula θ = arccos (d1 / d2), θ represents the first relative angle, d1 represents the second distance difference value, and d2 represents the second interval distance value.
