Abstract: The present invention relates to a distance measurement system comprising: a sensor unit for generating and transmitting a signal and receiving a reflected signal reflected back from an object; a buffer for temporarily storing data; and a control unit which calculates the distance to the object by measuring the time from when the signal is transmitted from the sensor unit to when the reflected signal is received. According to the present invention, the proposed distance measurement system uses an algorithm combining probability and moving average, thus having the effect of significantly improving the reliability of distance measurement compared to existing modes of distance detection.
