Embodiment 1

[0078] In order to more fully describe the calibration method provided by this embodiment, it will be described in conjunction with the user's virtual touch process; figure 2 ,Proceed as follows:

[0079] S01, judging whether the position of the depth detector has changed or whether the user has been replaced.

[0080] In the embodiment of the present application, a motion sensor is built into the depth detector, such as an accelerometer, a gyroscope, etc., and the sensor is used to monitor whether the depth detector has moved; at the same time, the user's face can be detected through the 2D camera configured on the display , and determine whether the user has been changed.

[0081] When the motion sensor detects that the position of the depth detector has changed, or the 2D camera detects that the viewing user has been replaced, a menu prompt will pop up on the display interface, prompting the user that the above status has changed, and recalibration is required to view no...

Embodiment 2

[0176] The embodiment of the present application also provides a system for realizing virtual touch calibration, such as Figure 4 shown, including:

[0177] Create cells, build cells, calculate cells, calibrate cells, compensate cells, and hint cells.

[0178] Create unit 01 for creating a virtual calibration menu;

[0179] The construction unit 02 is configured to use the plane on which the virtual calibration menu is displayed as a plane formed by the x-axis and the y-axis to establish a first coordinate system; Coordinate system coordinate representation;

[0180] A calculation unit 03, configured to calculate the correspondence between the first coordinate system and the second coordinate system;

[0181] The calibration unit 04 is configured to, according to the corresponding relationship, represent the coordinates of the user gesture position represented by the second coordinate system with the coordinates of the first coordinate system; Coordinates to correct the c...

Abstract

The invention discloses a method and system for achieving virtual touch calibration. The method includes the steps of establishing a virtual calibration menu, setting up a first coordinate system so as to display that the plane where the virtual calibration menu is located is formed by the x-axis and the y-axis, setting up a second coordinate system to express the gesture position of a user through coordinates in the second coordinate system, calculating the correspondence between the first coordinate system and the second coordinate system, expressing the coordinates of the gesture position, expressed in the second coordinate system, of the user through coordinates in the first coordinate system according to the correspondence, and correcting the correspondence between the gesture of the user and the virtual calibration menu according to the relation of the gesture position, expressed by the coordinates in the first coordinate system, of the user. Compared with the prior art, the method and the system have the advantages of improving accuracy of virtual touch and improving the sensory effect of the user.

Description

technical field [0001] The present invention relates to augmented reality technology, in particular to a method and system for realizing virtual touch calibration. [0002] Background technique [0003] Emerging augmented reality technology can make the interaction between the virtual world and the real world appear more direct and natural, and gesture-based human-computer interaction is an indispensable key technology in the interaction of augmented reality technology. Let real people or objects directly interact with 3D virtual projection objects, that is, let gestures interact directly with virtual objects, and users can directly control 3D virtual projection objects with gestures. This expression is natural and clear, making the experience of human-computer interaction more attractive. . [0004] In the prior art, the user interface and implementation method of 3D virtual projection and virtual touch include a depth detector, a binocular image parallax calculation m...
