Zusammenfassung: | The present invention relates to a position measuring terminal of an underground duct and a method for controlling the same. The method of the present invention comprises the steps of: receiving, from an information obtaining unit, a video obtained by photographing an object to be measured while the information obtaining unit is moved; receiving position information on the information obtaining unit including position, rotation, tilt, and scale from a sensing unit of the information obtaining unit while the information obtaining unit is moved; obtaining three-dimensional coordinates of the object to be measured and a peripheral area through a triangulation using the video obtained by photographing the object to be measured and inertial information; including t frames photographed at different positions in the video obtained by photographing the object to be measured, having a feature point in all frames, and designating an arbitrary point designated by a user in an n^th specific frame; extracting the arbitrary point designated by the user from all frames from 1 to t; and obtaining d having a minimized absolute value obtained by subtracting a color value of an arbitrary point designated by the user estimated at an (n-1)^th frame in response to a change of d which is the distance from an arbitrary point designated by an arbitrary user designated by the user to the object to be measured, from a color value of the arbitrary point designated by the user extracted from the n^th feature frame, satisfying 1 |
