Method and system for making a wig head shell

Abstract

The invention discloses a method for making a wig head shell, which includes: using a grating projector to project grating stripes onto the head of a shape-taking object where a wig needs to be made, and using a CCD camera to make a wig on the head of the shape-taking object from different positions According to the gray level information of the pixels of the captured grating stripes, the curvature change information of the captured grating stripes is obtained, and the image is determined according to the position information of the CCD camera and the curvature change information of the grating stripes. The relative coordinate information of all the pixel points of the grating stripes of the image, the relative coordinate information of all the pixel points is uniformly converted and as the head of the object to be modeled, the three-dimensional data of the head shell at the wig needs to be made; the model is produced according to the three-dimensional data The subject's head needs to make the head shell where the wig is made. The invention also discloses a wig head shell manufacturing system at the same time. The invention greatly shortens the time for taking models, thereby improving the efficiency of taking models, improving the precision of taking models, and improving user experience.

Description

technical field [0001] The invention relates to a wig making technology, in particular to a method and system for making a wig head shell. Background technique [0002] Wig head shell making is the first process of producing wigs, and taking the shape is the most critical step in this process. The main purpose is to obtain the curved surface shape of the customer's head shape in order to make a wig that fits the customer's head shape. [0003] At present, the hair products industry has two methods for taking the shape of the head, and the most widely used method is a method of taking the shape of the tape, that is, using a plastic wrap to tighten the shape of the customer's head, and then repeatedly wrapping the plastic wrap with the tape to fix the shape. [0004] However, this type-taking method is cumbersome to operate and the accuracy of the type-taking is inaccurate, and it is easy to be squeezed and deformed during the mailing process when the off-site type is taken, ...

AI Technical Summary

Problems solved by technology

[0006] This method has the following three defects. First, the mechanical probe is used to directly contact the collected data on the customer's head, and the customer will feel uncomfortable when the data is collected.

Second, the customer is required to maintain the same posture for a long time when using the probe to take the shape. When the probe is used to take the shape, if the position of the customer's head changes, the coordinates of the probe will change, resulting in inaccurate data collection; Third, this method is to use a probe to outline the general outline of the customer's head, and then use computer software to calculate the three-dimensional data of the customer's head. Since the data is not directly collected, the obtained data is not accurate.

Since this method needs to scan twice and synthesize the three-dimensional and two-dimensional data, it has the defects of long scanning time, long data processing time, and inaccurate final three-dimensional data.
