Online somatosensory three-dimensional modeling method and system based on Leap Motion

Abstract

The invention discloses an online somatosensory three-dimensional modeling method and system based on Leap Motion. The method comprises: carrying out gesture information pre-definition; and carrying out gesture training and recognition. The step of gesture information pre-definition includes: defining a three-dimensional modeling gesture; carrying out gesture data preprocessing; and constructing agesture data model. The step of gesture training and recognition include: constructing a gesture training sample set; constructing an HMM gesture training model; and carrying out gesture recognitionthree-dimensional modeling. In addition, the system is composed of a software interaction unit, an acquisition unit, a real-time communication unit, a data processing unit, a storage unit, a calculation unit and an execution unit. According to the invention, the user is assisted in carrying out online three-dimensional modeling based on a browser terminal by means of somatosensory interaction based on technical principles of virtual reality, human-computer interaction and computer graphics.

Description

technical field [0001] The invention belongs to the technical field of virtual reality and human-computer interaction, and in particular relates to an online somatosensory three-dimensional modeling method and system based on Leap Motion. Background technique [0002] With the continuous development of information technology, Computer Aided Design (Computer Aided Design) software has gradually developed from the traditional C / S (Client / Server) architecture to B / S (Browser / Server), which runs directly on the browser side. It supports online 3D modeling and product design in the cloud, and can provide enterprises with distributed collaborative design, information communication and knowledge sharing services. At present, the interaction between designers and online 3D modeling software still relies on the "mouse+keyboard" 3D modeling method. In addition, 3D modeling requires a long time to learn professional knowledge, resulting in relatively high learning costs for existing 3D...

Problems solved by technology

[0004] The present invention aims at the problem that Web-based 3D modeling software has poor support for somatosensory hardware device access, resulting in insufficient human-computer interaction in the 3D modeling process in the Web environment, and proposes an online somatosensory 3D modeling based on Leap Motion Method and system, by defining different types of gestures, creating 6 basic geometric bodies, and performing translation, rotation, and scaling operations on the created geometric bodies
