Claim 6:
7. The writing trajectory processing method according to claim 6, wherein smoothing the point sequence consisting of the plurality of first trajectory points and the midpoint of every two adjacent first trajectory points by the Bezier curve to obtain the plurality of second trajectory points, comprises:
taking a first one of the first trajectory points as a starting point parameter of the Bezier curve, a midpoint between the first one and a second one of the first trajectory points as a control point parameter of the Bezier, and the midpoint between the first one and the second one of the first trajectory points as an end point parameter of the Bezier curve, and calculating to obtain partial points in the second trajectory points by using a Bezier curve formula;
sequentially taking a midpoint of an i-th one of the first trajectory points and a (i+1)-th one of the first trajectory points as the starting point parameter of the Bezier curve, the (i+1)-th one of the first trajectory points as the control point parameter of the Bezier curve, and a midpoint of the (i+1)-th one of the first trajectory points and a (i+2)-th one of the first trajectory points as the end point parameter of the Bezier curve, and using the Bezier curve formula to calculate to obtain other points except the partial points in the second trajectory points, where i is a positive integer greater than or equal to 1;
the Bezier curve formula is: B(t)=(1−t)2P0+2t(1−t)P1+t2P2, wherein B(t) represents a second trajectory point, P0 represents the starting point parameter of the Bezier curve, P2 represents the end point parameter of the Bezier curve, P1 represents the control point parameter of the Bezier curve, and t is a variable, t∈[0,1].
