Quick fitting method and device for human body model and storage medium

Abstract

The invention discloses a rapid fitting method of a human body model. The method comprises the following steps: establishing a standard human body model in an initial posture; obtaining posture and body shape parameters of a target human body model, wherein the three-dimensional human body posture and body shape parameters correspond to skeletons and a plurality of base parameters of a three-dimensional standard human body model; selecting an initial posture base of a standard three-dimensional human body model according to the obtained posture parameters of the target human body model; according to the obtained bases and skeleton parameters of the plurality of groups of target human body models, starting fitting from the selected initial posture base; obtaining a three-dimensional human body model with the same body shape as the target human body; and obtaining a three-dimensional target human body model grid with the same posture as the target human body two-dimensional image. The initial posture bases of the three-dimensional standard human body model can be a plurality of preset initial posture bases including T-pose. According to the method, the fitting process of the standard human body model and the target human body model is optimized, a plurality of initial posture bases are used for replacing a traditional single T-pose initial posture, the process of driving the skeleton to move is optimized through the variable speed frame interpolation method, and the whole fitting process achieves good balance in time and effect.

Description

technical field [0001] The invention belongs to the field of human three-dimensional model modeling, and in particular relates to a fast fitting method of a human body model, in particular to a method, device and storage medium for fast fitting of a standard human body model and a target human body model based on multiple initial attitude bases. Background technique [0002] With the development of Internet technology, online shopping is becoming more and more popular. Compared with shopping in physical stores, online shopping has the advantages of a wide variety of products and convenient shopping. However, there are also some problems that are not easy to solve when buying goods online. The most important thing is that it is impossible to check the goods to be bought on the spot. Of all the product categories, this issue is most prominent for apparel products. Compared with shopping in physical stores where you can change clothes in real time to check the effect of cloth...

Problems solved by technology

In this modeling method, the parameters that are judged by the model and finally output by the neural network are only the parameters of the relevant nodes, and then the mature body shape of the SMPL model is used to make detailed adjustments consistent with the target human body posture. Although the amount of calculation is reduced, due to There are few input parameters, and the adjustment can only be completed on the basis of the SMPL prediction model, so it is difficult to output a particularly ideal human body model that is highly consistent with the target human body posture
