摘要： The motion tracking method disclosed herein suggests a method for precisely tracking the motion of a scanning device by correcting the surrounding information distortedly recognized due to the time differences between pieces of information regarding the surroundings of the device over one scanning cycle. The method, as a motion tracking method of a scanning device collecting the surrounding information corresponding to a plurality of the points of the surroundings, includes collecting the surrounding information, obtaining the displacement data of the scanning device using the surrounding information, updating the velocity of the scanning device using the displacement data of the scanning device, correcting the surrounding information using the updated velocity of the scanning device, and determining location and position information of the scanning device using the corrected surrounding information. According to the method herein, the motion of the scanning device may be more precisely tracked because the surrounding information is corrected based on the velocity of the scanning device.
