Embodiment Construction

[0043] like figure 1 As shown, a method for combining virtual sand paintings based on multi-sensing devices in this embodiment includes the following steps:

[0044] 1) Data acquisition: Use the data capture function of Leap Motion to obtain the original hand data drawn by non-contact sand paintings, and obtain the required hand data through the Hand Controller component; connect the PQ Labs G4S touch screen and the display through the interface , contact sand painting drawing is to scan the infrared rays emitted by the outer frame in real time. Once a finger or an object larger than the minimum blocking diameter blocks it, it can judge the hand data that has been in contact to ensure the correct transmission of the data. Through the TUIO protocol in the Obtain the hand touch data drawn by contact sand painting in Unity3D;

[0045] 2) Data processing: first, the feature extraction method is used to preprocess the raw data of the hand, and then new hand feature data is introdu...

Abstract

The invention belongs to the technical field of virtual sand painting drawing method, in particular to a virtual sand painting interactive combination method based on multi-motion sensing equipment. According the method, a data capture function of leap motion is firstly applied to obtain original hand data, thus an existing feature extraction method is adopted to preprocess the original data, newhand feature data is introduced to complete dynamic gesture tracking, gesture recognition is performed through template matching, and non-contact virtual sand painting drawing is completed by combining with a rendering effect. A PQLabs G4S touch screen is utilized to acquire touch information, a touch event is produced, a graph embedding method is adopted to convert the touch event into a featurevector for gesture recognition, and meanwhile contact virtual sand painting drawing is completed by combining with a sand grain rendering effect. Virtual sand painting drawing is performed through assistance of leap motion and a touch screen. Compared with real sand paintings, both three-dimensional drawing in the air and contact two-dimensional drawing are achieved, and the method can be well used for virtual sand painting drawing.

Description

technical field [0001] The invention belongs to the technical field of virtual sand painting drawing methods, and in particular relates to a virtual sand painting interactive combination method based on multi-body sensing equipment. The method is a non-contact virtual sand painting drawing based on leap motion and a touch screen based on PQ Labs G4S Controlled virtual sand painting drawing. Background technique [0002] As one of the cores of virtual reality technology, human-computer interaction shoulders the task of improving user immersion experience and system authenticity. The simulation of traditional painting art is one of the most challenging subjects in the field of computer art. While absorbing the nutrition of traditional painting art and promoting the achievements of traditional painting art, it puts forward new requirements for computer simulation painting technology. The virtual sand painting system can theoretically be integrated into any visualization system...
