摘要
A distance measurement method, medium, and apparatus for measuring a distance between the distance measurement apparatus and a target object are provided. The distance measurement method comprises counting pulses of a clock pulse signal having a low frequency during a period from when an optical pulse signal is applied to a target object by a distance measurement apparatus to when the optical pulse signal reflected from the target object is received by the distance measurement apparatus, counting pulses of the clock pulse signal during a period from when the optical pulse signal is received by the distance measurement apparatus to when the received optical pulse signal and the clock pulse signal correspond to each other, and calculating a distance between the distance measurement apparatus and the target object using the counting results. Accordingly, the distance can be measured with high accuracy using the optical pulse signal and the clock pulse signal, thereby reducing costs and power consumption.
