Quick three-dimensional display interacting device and method based on dual-structure light infrared identification

Abstract

The invention discloses a quick three-dimensional display interacting device and method based on dual-structure light infrared identification. The quick three-dimensional display interacting device comprises an image capturing system additionally provided with an infrared filter, dual infrared light sources and dual pattern templates, wherein the image capturing system is arranged between the dual infrared light sources and is aligned to an overlapped region radiated by the dual light sources. The method comprises the following main steps of: projecting a composite pattern to a hand part of an interactor through respective pattern samples by the dual light sources; shooting and acquiring the composite pattern by the image capturing system; and processing an image acquired by the image capturing system in real time, distinguishing a foreground from a background to obtain the approximate outline of the hand part, matching the obtained outline with the shape prestored in a data bank, judging the outline which has highest matching degree and the similarity exceeding the threshold as gesture made by the current interactor and making corresponding response to the gesture by a computer. The quick three-dimensional display interacting device and method disclosed by the invention can be applied to three-dimensional display equipment so as to achieve the bare-handed three-dimensional interaction function at a quicker algorithm and a more compact hardware structure.

Description

technical field [0001] The invention relates to a multimedia interactive design method, in particular to a fast three-dimensional display interactive device and method based on dual structured light infrared recognition. Background technique [0002] With the rapid development of 3D display technology, people's demands for interaction in 3D virtual scenes are becoming more and more urgent. Three-dimensional interactive technology allows users to perform various operations in a virtual three-dimensional scene, which can greatly improve the realism of interaction and make the interactive experience more natural. Different from the interaction of the two-dimensional display system (the interaction form has only three degrees of freedom), there are six degrees of freedom in the interaction of the three-dimensional space, that is, the displacement in the X, Y, and Z directions and the rotation around the three axes. This makes it necessary for researchers to develop new forms of...

Problems solved by technology

Secondly, these systems use composite structured light to detect the spatial posture of the hand, and process the color image under visible light (use skin color recognition technology to detect the human hand), which puts forward higher requirements on the environmental lighting conditions, and the current 3D The brightness of the full parallax display device is low, so the lighting of the scene cannot be too bright

Even the existing single-camera-based tracking technology has various deficiencies, and the method of simply matching the width of the finger image with the spatial distance is very imprecise
