Description

Three-dimensional fitting method

Technical Field

The invention relates to a three-dimensional fitting method, in particular to a three-dimensional fitting method applied to 3D deformation.

Background

With the popularization of electronic commerce, online shopping is favored by people due to the characteristics of convenience, time saving, money saving and the like. Network shopping has become the life habit of consumers and widely permeates the daily life of people.

However, for purchasing clothes on the internet, consumers may have trouble of trying on clothes and not knowing how to put on clothes. Although some apparel websites provide the functionality of a "virtual fitting room". However, these functions are based on the simple two-dimensional mapping of the user's head portrait and the web site's clothes to display fitting effect, but cannot display the real situation that the clothes are worn on the user's own, so that the user finds that the clothes are not suitable for wearing after trying on the clothes purchased through the web at home, resulting in a very high rate of return goods.

Therefore, it is worth those skilled in the art to think how to make the effect presented by the virtual fitting approach the actual situation that the user wears the clothes.

Detailed Description

Referring to fig. 1, fig. 1 shows a three-dimensional fitting method according to the present embodiment, which includes the following steps:

first, referring to step S1, fig. 2A and fig. 2B (fig. 2A is a schematic diagram illustrating a human body model scanned by a 3D scanner, and fig. 2B is a schematic diagram illustrating a first human figure graph cut at fig. 51), a human body model 5 is scanned by a 3D scanner 4 to form a first human figure graph cut at fig. 51. Wherein the manikin 5 further comprises a plurality of sensing marks 52, and the sensing marks 52 are evenly distributed on the surface of the manikin 5. In this way, the 3D scanner 4 is facilitated to scan, and the first stereograph 51 is also closer to a real scale.

Then, referring to step S2 and fig. 3 (fig. 3 is a schematic view of the garment mannequin 6), a garment 7 is worn on the mannequin 5 to form a garment mannequin 6. In which apparel 7 is the garment to be tried on.

Next, referring to step S3 and fig. 4A and 4B (fig. 4A shows a schematic diagram of the 3D scanner 4 scanning the clothing body model 6, and fig. 4B shows a schematic diagram of the first human figure and the clothing figure 61), the 3D scanner 4 is used to scan the clothing body model 6 to form a human figure and a clothing figure 61.

Thereafter, referring to step S4 and fig. 5 (fig. 5 is a schematic view of a first three-dimensional garment pattern, which is illustrated as profile 61A), the portion of first three-dimensional human figure profile contained in profile 51 is removed to form a first three-dimensional garment pattern, which is illustrated as profile 61A. Thus, first three-dimensional garment view profile 61A corresponds to the three-dimensional view profile of garment 7.

Then, referring to step S5 and fig. 6A and 6B (fig. 6A shows a schematic diagram of the 3D scanner 4 scanning the user 8, and fig. 6B shows a schematic diagram of the first and second solid human figure graph section 81), the 3D scanner 4 is used to scan the actual body shape of the user 8, so as to form a second solid human figure graph section 81. Specifically, the second three-dimensional figure 81 is the actual figure of the user 8, and the volume of the second three-dimensional figure 81 is larger than that of the first three-dimensional figure 51 (this is also taken as an example in the present embodiment).

Thereafter, referring to step S6 and fig. 7 (fig. 7 shows a schematic diagram of a first three-dimensional figure graph, where 51 is stretched to a second three-dimensional figure graph, 81), the first three-dimensional figure graph, where 51 is stretched or cut to the second three-dimensional figure graph, 81, and the stretching or cutting scale is defined as a 3D deformation. In detail, when the volume of the first solid figure profile 51 is smaller than that of the second solid figure profile 81, it is necessary to perform the stretching process on the first solid figure profile 51. On the contrary, when the volume of the first three-dimensional figure profile 51 is larger than that of the second three-dimensional figure profile 81, it is necessary to cut down the first three-dimensional figure profile 51 to be similar to the second three-dimensional figure profile 81, and this 3D modification is obtained.

Thereafter, referring to step S7, fig. 8A and 8B (fig. 8A is a schematic diagram illustrating an adjustment of the first stereoscopic decoration diagram before 61A, and fig. 8B is a schematic diagram illustrating a second stereoscopic decoration diagram before 61B), the first stereoscopic decoration diagram is adjusted according to the 3D modification, like 61A, to form a second stereoscopic decoration diagram before 61B. In the present embodiment, since the volume of solid chevron profile 51 is smaller than that of second solid chevron profile 81, this 3D deformation will cause first solid suit profile 61A to be stretched to form second solid suit profile 61B.

Then, referring to step S8 and fig. 9 (fig. 9 is a schematic diagram of the user figure and clothing image file 91), the second three-dimensional clothing image file 61B is combined with the second three-dimensional figure image file 81 to form a user figure and clothing image file 91. Specifically, the user figure and clothing figure 91 is a perspective view that simulates the user trying on clothing 7. Therefore, compared with the traditional two-dimensional map splicing method for displaying the fitting effect, the three-dimensional fitting method of the embodiment can show the actual situation of the user wearing the clothes, so that the user cannot generate too large fall with the virtual fitting effect after trying on the clothes purchased through the network at home, and the ratio of subsequent goods return is reduced.

In summary, the three-dimensional fitting method of the present embodiment can show the actual wearing situation of the user in a virtual manner.

The above-described embodiments are merely exemplary for convenience of description, and various modifications may be made by those skilled in the art without departing from the scope of the invention as claimed in the claims.
