Algorithm of Digital Dynamic Sculpture Expression Change Based on Virtual Reality Technology

The creation, expression and application of dynamic sculpture public art in public environment space combines traditional dynamic sculpture art with contemporary public art in a specific angle, and then tries to sort out the contribution and function of dynamic sculpture art to contemporary public art based on actual creation. Dynamic sculpture has played an important role in modern sculpture art, and a large number of outstanding artists and works have emerged, which has revolutionized the form of sculpture art. Expression recognition technology is a challenging cross-cutting subject involving emotion calculation, image processing, machine vision, motion tracking, pattern recognition, biometric identification, physiology, psychology and other research fields. It is an important part of emotion calculation and human-computer intelligent interaction. However, because two-dimensional images are the projection of three-dimensional objects onto a two-dimensional plane, the texture, shape and other features will inevitably be lost during the projection process, so gesture recognition based on virtual reality (VR) has become the research focus and center in this field. This paper proposes a digital dynamic sculpture expression change algorithm based on VR technology, which involves the method of dynamic sculpture expression feature extraction, the sculpture expression change extraction algorithm based on VR, the analysis of stereo display algorithm based on projection transformation, and the analysis of stereo display algorithm. It can make people pay attention to the interactive communication with sculpture in the process of use, the feeling of sculpture artistic image and personalized recreation. Through the dynamics of sculpture structure and elements, we can meet people’s growing aesthetic needs to a certain extent.
