  • We propose a method with the following procedure.Firstly,we correct the elevation of some rough ground by surface fitting.Secondly,we track the contour point by building triangle mesh and eliminate burrs by weighting quadratic polynomial.Finally,we interpolate to get the smooth contour by spline function with contourinterval.The experimental results show that our method can generate uncrossed and smooth contour in less loss of precision.
