Abstract:
PURPOSE: A leg extracting method using a distance sensor, a human tracking cruise method of a mobile robot using the same, and a mobile robot are provided to streamline structure and reduce manufacturing costs by extracting a leg shape of a man using only a distant sensor to trace the man. CONSTITUTION: A leg extracting method using a distance sensor comprises following steps. Reference leg data is set up and extracts the leg section of a man from data points scanned by a distance sensor(S61). The multiple data points are obtained by the scanning of a distant sensor(S62,S63). The multiple leg data points about the leg shape of the man are extracted from multiple data points based on the reference leg data(S64).
