The invention discloses a method for improving size matching of an outer tent and an air column of an inflatable tent. The method comprises the following steps that S1, preset deformation parameters of the outer tent in the machining process and preset deformation parameters of the air column when the air column is pressurized to rated pressure are obtained; s2, on the basis of the preset deformation parameters of the outer tent, compensation calculation is conducted on the blanking size of the outer tent sample division piece; cutting and splicing outer tent sample dividing pieces according to the compensated blanking size to form an outer tent; s3, based on the preset deformation parameters of the air column, performing compensation calculation on the modeling size of the air column; and the air column is manufactured according to the compensated modeling size. The technical problems that in the prior art, shrinkage of an outer tent material in the machining process and expansion of an air column material in the pressurized state are not considered, the size of a formed outer tent is mismatched with the size of the air column, and then air column installation bending, product assembling difficulty, material waste and appearance quality defects are caused are solved.

The invention aims to provide a virtual fitting retail customization method and system based on three-dimensional virtual model clothing size matching, and solves the problems that online shopping is unsatisfactory to received clothing due to the type and style and unfit in size, the clothing can return the articles, the returned goods means profit loss for online shops, and the customer experience is poor. The cost is increased; and the customer satisfaction is reduced. A user needs to pay time, energy and economic cost to return and change goods. And a three-dimensional virtual model matching function: comparing the body measurement size of the user with the size parameter of the clothes of the merchant, and matching to obtain the size suitable for the user demand. The buyer and the seller have benefits, consumers can obtain commodities with proper sizes, and merchants can reduce commodity refunding and changing caused by improper sizes. The virtual fitting function of the three-dimensional virtual model solves the problem that due to the fact that fitting cannot be achieved in online shopping, the size is proper, but the model and the style are not proper, goods return and goods exchange are caused. And a three-dimensional virtual model customization function: an online merchant processes commodities conforming to the body size of the consumer according to data in the model, so that the clothes effect of on-site body measurement is achieved.

This invention discloses a method and system for optimizing gift design schemes by integrating multimodal user demand perception, relating to the field of data processing technology. The method includes: acquiring a set of gift size demand features; calculating the weight coefficients of each gift size demand feature through sensitivity analysis combined with historical gift design schemes; constructing a collaborative optimization objective function for gift size, using size design parameters as independent variables and maximizing the overall matching degree as the optimization objective, while setting cost constraint thresholds and material size matching thresholds as optimization constraints; acquiring the gift size design range, iteratively solving the collaborative optimization objective function to obtain multiple candidate size design schemes that satisfy all constraints, and the overall matching degree corresponding to each candidate scheme; selecting the candidate size design scheme with the highest overall matching degree and single-dimensional matching degree to obtain the optimal gift size design scheme set. This invention effectively improves the overall matching degree of gift size design under multimodal user demand.
