Embodiment 1

[0022] Embodiment one: if figure 1 As shown, the wearable 3D gesture interaction system includes a portable computer (1), a camera (2), a micro-projector (3) and some colored markers (4). The interactive system has low requirements for hardware, and no requirements for micro-projectors and cameras, so the system cost is low. In order to make the picture taken by the camera the picture that the user sees, and the hand movement does not affect the projection effect, such as figure 1 As shown, the micro-projector and camera are placed on the hat.

Embodiment 2

[0023] Embodiment two: the use method of wearable three-dimensional gesture interaction system, such as figure 2 As shown, the specific steps are as follows:

[0024] ①, mark recognition;

[0025] ②, action recognition;

[0026] ③. Response output.

[0027] The mark recognition described in the above step ① is to obtain the information of the colored mark on the user's finger through the camera, and obtain its coordinate information through image segmentation. The specific steps are as follows:

[0028] (1). Obtain key frame images.

[0029] (2) Carry out image segmentation on the colored markers in the key frame image, obtain the coordinates of each colored marker, and calculate the relative position of each marker as a gesture.

[0030] The action recognition described in the above step ② performs gesture interaction, and its specific steps are as follows:

[0031] (3) Is it a multi-touch gesture? If it is a multi-touch gesture, go to step (7), otherwise go to step (4...

Abstract

The invention discloses a wearable three-dimensional gesture interaction system and a suing method thereof. The system consists of a micro projector, a common camera, a portable computer, and a group of simple and easy marks. The function of human-computer interaction by using gestures and a three-dimensional graphical interface is realized through simple and easy computer vision computation. In the wearable three-dimensional gesture interaction system, a three-dimensional graphical interface is more vivid and the interaction mode is more flexible through a projection screen marked three-dimensional graphical interface mode and a virtual mouse gesture. The wearable three-dimensional gesture interaction system has simple equipment and low cost and can meet the requirements on mobile equipment.

Description

technical field [0001] The present invention relates to a wearable three-dimensional graphic interface gesture interaction technology, in particular to a wearable three-dimensional gesture interaction system based on monocular vision and marking, using gestures for human-computer interaction and its use method. Background technique [0002] With the continuous improvement of people's requirements for natural interaction, human-computer interaction through gestures has become a mainstream trend. In order to operate virtual data anytime and anywhere, wearable computer technology is a feasible method to solve this problem. With the development of pico projectors, it is an irreversible trend that pico projectors become the standard configuration of mobile devices. At the same time, people are gradually dissatisfied with the too small display screen of mobile devices. Therefore, projecting the interface onto a plane to expand the screen size has become a research hotspot. [0...
