Title:
DISTANCE MEASUREMENT METHOD, AND READABLE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/160414
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and particularly relates to a distance measurement method, and a readable medium and an electronic device. The distance measurement method comprises: a first electronic device establishing a communication connection with a second electronic device, the first electronic device receiving a distance measurement instruction, and the first electronic device receiving a plurality of groups of acoustic wave signals which are sent by a loudspeaker in the second electronic device; then, the first electronic device determining, according to the plurality of groups of acoustic wave signals, sending moments and acoustic wave velocities, a real-time distance between the first electronic device and the second electronic device when each group of acoustic waves is received by the first electronic device; and finally, the first electronic device continuously refreshing and displaying a calculated real-time distance between the first electronic device and the second electronic device. The distance measurement method is simple and convenient to operate, thereby improving the user experience; and even if a first electronic device moves slightly, the first electronic device can still accurately display, in real time, a change in the distance between the first electronic device and a second electronic device, thereby improving the display precision.
