Abstract
A distance measurement method. A first electronic device establishes a communication connection to a second electronic device. The first electronic device receives a distance measurement instruction. The first electronic device receives a plurality of groups of sound wave signals sent by a speaker in the second electronic device. Then, the first electronic device determines, based on the plurality of groups of sound wave signals, a sending moment, and a sound wave velocity, a real-time distance between the first electronic device and the second electronic device when each group of sound wave signals are received by the first electronic device. Finally, the first electronic device continuously refreshes and displays the real-time distance between the first electronic device and the second electronic device that is obtained through calculation to improve display precision.
