Electronic whiteboard positioning method and electronic whiteboard positioning system

Abstract

The invention discloses an electronic whiteboard positioning method, which comprises the following steps of: 1, selecting four point coordinates in an electronic whiteboard coordinate system as whiteboard reference point coordinates, selecting four point coordinates in a computer screen coordinate system as computer screen reference point coordinates, and building a mapping relationship between two reference point coordinates; 2, substituting the coordinates into a whiteboard coordinate and computer screen mapping relationship to solve parameter values; 3, building a mapping relationship between electronic whiteboard measuring coordinates and computer screen points according to the parameter values obtained through calculation; and 4, performing any position positioning in a located region of an electronic whiteboard according to the mapping relationship. The electronic whiteboard positioning method has the advantages that an accurate mapping relationship between the electronic whiteboard measuring coordinates and the computer screen point coordinates is built; the errors of an electronic whiteboard plane due to ideal easel plane rotation are eliminated; the positioning method is simple; and the positioning effect is precise.

Description

technical field [0001] The invention relates to the technical field of electronic whiteboard positioning, in particular to an electronic whiteboard positioning method and system. Background technique [0002] Interactive electronic whiteboard is a high-tech product developed by combining cutting-edge electronic technology, software technology and other high-tech means. It is a newly emerging high-level teaching, training and conference demonstration equipment. By applying infrared or electromagnetic principles, it can combine computers and projectors to realize paperless office and teaching. It can write directly with a pen like ordinary whiteboards or teaching blackboards, and then input them into computers. Compared with projectors and ordinary whiteboards , The electronic whiteboard has its own advantages.
