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 present invention provides a positioning method for an electronic display system, comprising the following steps: setting at least three camera devices at different positions on the edge of a display screen; acquiring shooting angle information of the camera devices when there is an obstruction; Obtaining the number of shooting angles of each camera according to the information; determining the combination mode of the shooting angle information of the camera device according to the number of shooting angles, and obtaining the first coordinate of the occluder according to the combination mode of the shooting angle information, And locate the obstruction according to the first coordinates. The positioning method of the electronic display system of the present invention is low in cost, simple in realization, and can realize multi-point 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...
