The invention provides an automatic customized shoe generation system which comprises a last model generation module, a plane design drawing processing module, a sole model generation module and an upper 3D model generation module.

And the last-entering model generating module is used for generating a last-entering model based on the smooth last model, the vamp thickness and the insole thickness. As shown in fig. 1, the last model 2 is a three-dimensional structure composed of data of an upper 3 and an insole 4, and the light last model 1 is wrapped in the three-dimensional structure. The three-dimensional structure of the last model 2 comprises a thickness parameter which is matched to the thickness of the upper 3 and the insole 4. In one or more embodiments, the last model 1 may be from a designated last model or a last model that is customized to the user's foot shape data. The thickness of the shoe upper 2 depends on the thickness of the target upper material. Specifically, the thickness of each portion is determined by the thickness of the target upper material when the foot surface 3 portion of the last model 1 is attached. Preferably, the thickness of said target vamp material is assigned according to the front and rear portions of the vamp 3, respectively. In the above embodiment, the thickness of the insole 4 depends on the thickness of the target insole material, specifically, the thickness of each part when the insole material is attached to the bottom of the last model foot. Preferably, the thickness of the target insole material is assigned according to the front and rear portions of the insole, respectively. In the above embodiment, the distance between the last model 2 and the last model 1 is determined according to the thickness of the shoe upper and the shoe sole.

And the plan design drawing processing module is used for adjusting at least one shoe style design characteristic of the target shoe style plan design drawing according to the last putting model and generating a target shoe style design drawing mapping. And the target shoe style design drawing mapping is matched with the last putting model. In one or more embodiments, as shown in fig. 2, the target shoe money plan view 5, including multiple views from side, bottom, etc., may be from a target shoe money for athletic shoes, geriatric shoes, etc., and may include shoe money design features.

In the above embodiment, the extension of the sole-side contour 7 in the insole width direction of the last model 2 matches the bottom surface of the last model 2. The first algorithm takes the sole inner face model 10 and the sole bottom face model 11 as input, and connects the edges of the two to generate the 3D model 12 of the sole outer contour. The module can also be attached to the inner surface and the bottom surface of the output sole, so that more flexibility is provided for subsequent automatic design. In the above embodiment, the first algorithm may also obtain the gate line 13 based on the sole inner face model 10 and the bottom surface of the last model 2.

s041, extending upwards to a curved surface at the ankle of the last model to a highest point of a curve at a welt which is higher than or equal to the outline of the upper side;

s042, cutting the curved surface at the ankle of the extended last filling model by using the curved surface at the upper side outline shoe mouth;

and S043, removing the part, higher than the curve of the vamp of the upper side profile, of the shoe vamp to generate a 3D model of the vamp profile.

14. The method according to claim 11, wherein the second algorithm in the step of S04 comprises the steps of:

s041', extracting a curve at the position of the upper side outline shoe opening, and generating a 3D outline of the shoe opening according to the curved surface at the ankle of the last-entering model;

s042', connecting the 3D outline of the welt and the die line along the outline curved surface of the last-in model vamp to generate a vamp outline;

and S043', adding a thickness parameter to the vamp contour to generate a 3D model of the vamp contour.

15. The method of automatically creating a customized shoe according to claim 11, wherein the method of automatically creating a customized shoe further comprises:

and S05, adding sole design characteristics on the basis of the sole outer contour 3D model to generate a customized sole 3D model.
