Three-dimensional modeling method for human hands

Abstract

The invention discloses a three-dimensional modeling method for human hands. The three-dimensional modeling method comprises the steps that the hand model is searched from a training set to act as thetemplate and nodes are drawn for the template; the template is matched with other samples in the sample set and the parameter of the rotating angle of each node of the template corresponding to the samples is determined; a matrix attitude change compensation matrix related to the attitude information is trained through the attitude information trained in the step 2; attitude unification is performed on the model in the sample library and the main component is extracted, and the matrix used for depicting different shapes is determined; and the template and the matrix are determined through thetraining and then various hand models can be depicted by manually assigning the parameter through the linear hybrid skin algorithm and parameter integration. The method of performing realistic modeling of multi-attitude gestures through the single three-dimensional hand template is realized, and different characteristics of different figure hand shapes can be reflected without using three-dimensional laser scanning so that the cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of computer vision and graphics, and relates to a three-dimensional modeling method, in particular to a three-dimensional modeling method for human hands. Background technique [0002] Accurate modeling of hands has become more and more important at present, because with the rapid development of artificial intelligence in the past few years, electronic devices represented by computers and mobile phones have played an increasingly important role in human society. The demand for more convenient and humanized human-computer interaction is becoming stronger and stronger. Considering that gestures are almost the second most important information after language in human-to-human communication, it is believed that gestures will also play a decisive role in human-computer interaction. [0003] So far, although there are not many discussions on 3D modeling of human hands, the research on 3D modeling has been quite m...

AI Technical Summary

Problems solved by technology

Due to the finer hand movements, more accurate modeling of human hand contours is required, but neither of the above two methods can meet the needs of precise hand modeling

At present, 3D laser scanning is required for accurate modeling of the hand, and repeated scanning is required when the shape of the hand changes, which is costly, inefficient, and restricted by the environment and equipment
