Further, as shown in fig. 2, the position information and distribution of each control point of the PH curve, a preferred rule of the structure of each control point is as follows:
wherein B isi=[xi,yi]T: i is 0, and 1 … 15 is the control point of the PH curve; epsilon is the fairing approximation error, and the control polygon length l, l' is:
by substituting the above-mentioned control pointsThe corner fairing C can be obtained4Wherein t is a curve parameter,is the Bernstein basis function, where the resulting initial processing path is composed of a mixture of linear and PH curve segments.
Step three:
when the constraint conditions are met, prospective speed planning is carried out to determine the speed of the speed danger points, and an S-type acceleration and deceleration strategy based on fourth-order polynomial jump is adopted to determine the acceleration, uniform speed and deceleration time of each tiny line segment;
