Image breakpoint interpolation algorithm based on the smooth gradient
MA Rui-tao · Jiguang zazhi · 2013
During the detection processing of 3D road information employing the structure laser triangulation method,it is unavoidable for breakpoints due to the shadow.In terms of geometric area,an image breakpoint interpolation algorithm based on the smooth gradient is proposed in this paper.By means of the character of smooth gradient of curve,the gradient values of the coordinate of breakpoint can be figured out.Subsequently,based on the triangular geometrical relationship,the coordinate values of missing pixels are calculated.Three-dimensional morphology can be recovered on the basis of contour line.The experiment results illuminated that the proposed algorithm are simple,reliable,and robust.
