Abstract
Proposed is a method of measuring the slope of a drainpipe while moving through the drainpipe. The method includes following steps: a) continuously measuring a slope of a pipe using a slope sensor disposed in a vehicle when the vehicle moves; b) measuring distances to a ceiling of the pipe in real time through non-contact sensors disposed at four positions, that is, at both sides of front and rear portions the vehicle, the step b) being performed simultaneously with the step a); and c) calculating slope differences, which are the degrees of inclination to the front, rear, left, and right using trigonometry and then correcting the slope by reflecting the slope differences to the slope measured in the step a), when there are differences in the distances measured in step b).
