Description

Technical Field

[0001] This invention belongs to the field of VR virtual display technology, and relates to a 3D cloud display system and method for virtual exhibition halls based on VR technology. Background Technology

[0002] With the rapid development of Internet 3D technology and VR virtual reality technology, virtual exhibitions are becoming increasingly popular. Virtual exhibitions have the advantages of low cost and high efficiency. At the same time, virtual exhibitions should also ensure the authenticity of exhibitors, especially virtual clothing exhibitions. Therefore, in order to ensure the experience of exhibitors in virtual clothing exhibitions, it is necessary to analyze the effectiveness of virtual clothing exhibitions.

[0003] Currently, the analysis of the effects of virtual fashion shows mainly focuses on the display effect of virtual models of clothing. However, the analysis of the matching effect between clothing and booths is still relatively superficial and one-sided. Obviously, this analysis method has the following problems: 1. The compatibility between virtual booths and exhibited clothing and the lighting effects affect the display effect of clothing. Current technology does not analyze the style compatibility between virtual booths and exhibited clothing, as well as the brightness and color temperature of booth lighting. As a result, it cannot effectively guarantee the display effect of exhibited clothing, reduce the aesthetics of exhibited clothing, and also cannot guarantee the experience of exhibitors.

[0004] 2. The suitability of clothing to exhibitors determines their purchasing desire. Current technology does not build virtual models of exhibitors based on their basic information, making virtual try-ons impossible. Consequently, it is impossible to intuitively understand the suitability of clothing to exhibitors. Furthermore, it does not analyze the matching between clothing and exhibitors based on their clothing needs and scenarios, thus failing to effectively improve the experience and realism of exhibitors in virtual clothing exhibitions. To a certain extent, this also hinders the increase in clothing sales at virtual clothing exhibitions. Summary of the Invention

[0035] Optionally, basic information includes gender, height, weight, and full-body image, while demand information includes clothing requirements for specific scenarios and preset prices.

[0036] Optionally, the compatibility evaluation coefficients between the target exhibitor and each candidate garment are analyzed.

Also, extract the reference color scheme of each candidate garment from the virtual model of each candidate garment, denoted as D0. i′ , where i′ represents the number corresponding to each candidate garment, i′=1′,2′......n′.

[0038] Based on the clothing demand scenarios of the target exhibitors, we analyze the reference clothing types corresponding to the target exhibitors. Simultaneously, we extract the types corresponding to each candidate clothing from the cloud database, and then analyze and obtain the compatibility coefficient between the target exhibitors' clothing demand scenarios and each candidate clothing type, denoted as δ. i′ .

Simultaneously, we extract the types corresponding to each candidate clothing from the cloud database, and then analyze and obtain the compatibility coefficient between the target exhibitors' clothing demand scenarios and each candidate clothing type, denoted as δ. i′ .

[0109] It should be noted that clothing types include short-sleeved shirts, jackets, and down jackets.

[0110] The above analysis of the reference clothing types corresponding to the target exhibitors is as follows: the clothing demand scenarios corresponding to the target exhibitors are compared with the reference clothing types corresponding to each set clothing demand scenario to obtain the reference clothing types corresponding to the target exhibitors.

[0111] The above analysis yielded the matching coefficients between the target exhibitor's clothing needs and the various candidate clothing types. The specific analysis process is as follows: Each reference clothing type corresponding to the target exhibitor is compared with each candidate clothing type. If a reference clothing type corresponds to the target exhibitor and a candidate clothing type, the matching coefficient between the target exhibitor's clothing needs and that candidate clothing type is denoted as a1. If none of the reference clothing types correspond to the target exhibitor and a candidate clothing type are the same, the matching coefficient between the target exhibitor's clothing needs and that candidate clothing type is denoted as a2. Thus, the matching coefficient δ between the target exhibitor's clothing needs and each candidate clothing type is obtained. i′ , where δ i′ The value can be either a1 or a2, and a1 > a2, where a1 and a2 are both natural numbers.

[0112] According to the calculation formula The compatibility evaluation coefficient β between the target exhibitor and each candidate garment was obtained. i′ Where R represents the preset price corresponding to the target exhibitor, R i′ Let λ represent the price corresponding to the i′th candidate garment, and λ1, λ2, and λ3 be the weighting factors corresponding to the set color tone, price, and type adaptation coefficients, respectively.

[0113] This invention analyzes the compatibility evaluation coefficients between target exhibitors and each candidate garment, providing an intuitive understanding of the compatibility between the garments and the exhibitors. This enhances the exhibitors' experience and sense of realism in the virtual clothing exhibition, but to a certain extent, it does not increase the sales volume of garments in the virtual clothing exhibition.

[0114] The exhibitor clothing filtering module is used to filter out the target suitable clothing for the target exhibitor.

[0115] In a specific embodiment, the target suitable clothing corresponding to the target exhibitor is selected. The specific selection process is as follows: the suitability evaluation coefficients of the target exhibitor and each candidate clothing are compared, and the candidate clothing with the largest suitability evaluation coefficient is selected as the target suitable clothing corresponding to the target exhibitor.

[0116] The display terminal is used to display the target-fitting clothing for the target exhibitor.

[0117] The cloud database is used to store the sets of reference design elements corresponding to each age group of the audience, the sets of reference styles corresponding to each age group of the audience, the area of ​​each virtual booth in each virtual exhibition area, the position of each virtual light, the position of each light-transmitting area in the virtual exhibition hall corresponding to a specified virtual clothing exhibition, the reference natural brightness corresponding to daytime, the required lighting brightness corresponding to each exhibitor, the type and standard light color temperature of each decoration in each virtual booth, the style of each exhibitor's exhibited clothing, and the reference light color temperature and price corresponding to each weather condition.

[0118] Please refer to Figure 2 As shown, a 3D cloud display method for virtual exhibition halls based on VR technology includes the following steps: Step 1: Construct virtual models of each exhibitor's corresponding exhibited clothing.

[0119] Step 2: Analyze the virtual exhibition area corresponding to each exhibitor.

[0120] Step 3: Analyze the virtual booths of each exhibitor in the designated virtual apparel exhibition area.

[0121] Step 4: Analyze the virtual environment information of the virtual booths in the virtual exhibition areas of each exhibitor in the designated virtual apparel exhibition.

[0122] Step 5: Collect basic information and demand information of the target exhibitors, and obtain the candidate clothing items for each target exhibitor.

[0123] Step Six: Analyze the compatibility evaluation coefficients between the target exhibitors and each candidate garment.

[0124] Step 7: Select the best-suited clothing for the target exhibitors.

[0125] Step 8: Display the target-suitable clothing for the target exhibitor.
