Abstract
A range-finding method, a apparatus, a terminal system, and a computer-readable storage medium are provided. The range-finding method includes: transmitting a first check code from a transmitting terminal to a receiving terminal by using a first communication technology; transmitting a modulated signal from the transmitting terminal to the receiving terminal by using a second communication technology different from the first communication technology, where the modulated signal carries a second check code; acquiring a first moment at which the modulated signal is transmitted and a second moment at which the modulated signal is received; demodulating the second check code in the modulated signal; acquiring a range-finding confidence according to the first check code and the demodulated second check code; and acquiring a measured distance between the transmitting terminal and the receiving terminal according to the first moment, the second moment, a transmission speed of the modulated signal, and the range-finding confidence.
