Embodiment approach

[0124] The present invention is not limited to the above embodiments. For example, the electronic display system positioning device and method of the present invention can be used to perform multi-point positioning of more than three points. When performing multi-point positioning of more than three points (for example, four-point positioning), according to the formula (1), the shooting angle information of each camera device is combined to solve in pairs, and the actual coordinates of the occluder are obtained by comparison. The above different implementation modes All positioning methods of the electronic display system can be applied to multi-point positioning of more than three points, so as to make the positioning method simpler and more reliable.

[0125] In addition, by understanding the technical solution of the present invention, those skilled in the art will realize that the shooting angle information of all the camera devices is combined to solve in pairs, or the sho...

Abstract

The invention provides a positioning method of an electronic display system, comprising the following steps of: arranging at least three cameras at different positions of the edge of a display screen; acquiring the information of shooting angles of the camera when opaque objects exist; according to the information of the shooting angles, obtaining the number of the shooting angles of all the cameras; according to the number of the cameras, determining the combining mode of the information of the shooting angles of the camera; obtaining a first coordinate of the opaque objects according to the combining mode of the information of the shooting angles; and carrying out positioning to the opaque objects according to the first coordinate. The positioning method of the electronic display system has low cost and simple implementation and can realize multipoint positioning.

Description

technical field [0001] The invention relates to the field of electronic display systems, in particular to a positioning method for the electronic display system, and also relates to a positioning device for the electronic display system. Background technique [0002] As a new type of computer input device, the positioning device of the electronic display system makes the human-computer interaction more intuitive. Because it brings great convenience to the user, the positioning technology of the electronic display system is not only applied to personal portable information products, but also to The field has covered various fields such as information appliances, public information, electronic games, and office automation equipment. The positioning devices of the existing electronic display systems have various forms, and each has its own shortcomings. For example, the Chinese invention patent with the publication number CN1942853A discloses a touch positioning panel with a t...
