Research on Automatic Generation Algorithm of Dispensing Trajectory Based on Sole Model
To achieve quantitative and uniform automatic gluing of irregular area of multistyle sole,we propose an automatic generation algorithm of dispensing trajectory based on parametric model of sole contour.Selecting key pa-rameters such as the length of sole sample,the length of the outer waistline,and the length of the heel center,establish a coordinate system for the shoe pattern,solve for the contour feature data points of the sole,and divide the sole area.Choosing NURBS curve to construct a first-order continuous parametric equation of sole contour curve.The sole con-tour curve of equidistant offset was established to determine the edge gluing curve of the upper surface of the sole.The equal arc length discretization method was used to realize the equidistant dispersion of the edge gluing curve and the generation of gluing trajectory.Using Isometric linear scanning method in the irregular area surrounded by the edge gelatinizing curve to solve the intersection of the scanning line and the gluing curve of the edge contour,and automati-cally generate gluing track on upper surface of sole.Experimental results show that this method can achieve uniform and quantitative gluing of the edge and upper surface of sole.
