Abstract

The invention discloses an ultrasonic hand gesture recognition based AR (augmented reality) dress-up game projection method and an ultrasonic hand gesture recognition based AR dress-up game projection system. The method includes: recognizing hand gestures according to ultrasonic frequency changes, and sending corresponding instructions to select a clothing virtual model; acquiring 3D model data of a user body through ultrasonic 3D imaging to construct a 3D model of the user body; subjecting the 3D model of the user body and the selected clothing virtual model to data superposition to acquire a hybrid model, and storing; converting digital signals of the stored hybrid model into optical signals, and performing 3D projection to project on a projection screen. The method and the system have advantages that the corresponding instructions are sent after ultrasonic hand gesture recognition to control selection of the clothing virtual model, and the selected clothing virtual model and the 3D model of the user body are synthesized to project a 3D image of the user wearing virtual clothing, so that a 3D dress-up effect of the user body is realized, high immersion and man-machine interaction are realized, and 3D stereo dress-up effects and high interestingness are achieved.

Description

technical field

[0001] The present invention relates to the field of AR projection technology, in particular to an AR dressing game projection method and system based on ultrasonic gesture recognition. Background technique

[0002] Dress up games are popular games on the web. Put on or take off clothing, accessories, etc. for graphic cartoons or star characters through keyboard and mouse operations.

[0003] The dress-up games on the market generally require the use of a physical keyboard or mouse to operate, and generally only the preset flat characters can be changed, and the user's own body cannot be 3D changed. Human-computer interaction Not strong enough, the sense of immersion in the game is not enough, there is no 3D stereoscopic effect, and the fun is not strong enough. Contents of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and propose an AR dress-up game projection method and system base...

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Utilize one or more ultrasonic sound sources to simultaneously emit ultrasonic waves with a constant frequency (20-22KHz), and use a microphone or other ultrasonic receiving devices to receive ultrasonic waves. According to the Doppler effect, if there is no object moving around, the ultrasonic frequency received by the ultrasonic receiving device will not change. If an object moves towards the direction close to the ultrasonic sound source, the ultrasonic frequency received by the ultrasonic receiving device will If the object moves away from the ultrasonic sound source, the ultrasonic freq...
