Problems solved by technology
[0003] However, the existing VR technology does not add any hardware. When the user is watching the VR screen, when answering the phone or reading the text message, but because the user is wearing a helmet, he cannot know the surrounding environment and cannot move his hand accurately. Into the area detectable by the camera, and cannot accurately perform actions with hands

The invention discloses a method and device for utilizing gesture control to achieve virtual reality interaction. The method comprises the following steps of firstly constructing a gesture image library and establishing mapping relation between a gesture image and hand posture parameters through a camera and data gloves; preprocessing a gesture image, along with preprocessing of a display picture when a picture is shot; extracting gesture image characteristic, extracting an H0G and a chromaticity histogram to serve as gesture characteristics and determining the original combined weight of shape and color characteristics; then retrieving a single viewpoint gesture image, improving an LSH index algorithm, establishing an index performance prediction model and optimizing index parameters. The device for utilizing the gesture control to achieve the virtual reality interaction is simple in structure and convenient to operate, a gesture can be directly adopted to control achievement of virtual reality, the usability of the virtual reality is improved, and the method and device are worthy of popularization.
Description
technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method and a device for realizing virtual reality interaction through gesture control. Background technique [0002] With the rapid development of science and technology, various new technologies and new inventions emerge in endlessly, and are quickly applied and served in society, which greatly promotes economic development. Virtual reality, referred to as VR technology, also known as spiritual technology or artificial environment, is the use of Computer simulation generates a three-dimensional virtual world, providing users with simulations of senses such as vision, hearing, and touch, allowing users to observe things in the three-dimensional space in a timely and unlimited manner as if they were actually there. When the user moves the location, the computer can immediately perform complex calculations and send back accurate 3D world images to create a sense of presen...
