Ultrasonic hand gesture recognition based AR (augmented reality) dress-up game projection method and ultrasonic hand gesture recognition based AR dress-up game projection system

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...

Problems solved by technology

[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 based on ultrasonic gesture recognition, so as to solve the problem that the human-computer interaction of the dress-up game in the prior art is not strong, the game immersion is not enough, and there is no 3D effect. Three-dimensional effect, technical problems that are not interesting enough
