Human body model driving method and device and storage medium

Abstract

The invention discloses a human body model driving method, and the method comprises the steps: obtaining the posture and body shape parameters of a target human body model, and enabling the three-dimensional human body posture and body shape parameters to correspond to the skeleton and a plurality of basic parameters of a three-dimensional standard human body model; establishing a standard human body model in an initial posture; inputting the obtained multiple groups of basis and skeleton parameters into a standard three-dimensional human body model for fitting; obtaining a three-dimensional human body model with the same body shape as the target human body; driving the skeleton to move from the initial posture to the target posture; and obtaining a three-dimensional target human body model grid with the same posture as the target human body two-dimensional image. According to the method, fitting of the standard human body model and the target human body model is optimized, an animation series from the initial posture to the target posture is formed, and the process of driving the skeleton to move is optimized by using the variable-speed frame interpolation method, so that the whole fitting process achieves a good balance in time and effect.

Description

technical field [0001] The invention belongs to the field of human body three-dimensional model modeling, and in particular relates to a human body model driving method, in particular to a method, device and storage medium for driving a standard human body model and a target human body model based on frame insertion technology. 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 clothing, online clothi...

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
