Abstract

The invention discloses a binocular vision based interaction method. The method mainly comprises the steps that a binocular camera is mounted in front of a screen and covers a certain range in front of the screen; a user moves a pure color target, and a calculation unit controls the binocular camera to synchronously acquire left and right eye images and identify the pure color target, and calculates three-dimensional spatial information of the pure color target; and if the pure color target enters a preset effective spatial region range, the calculation unit maps spatial coordinates of the pure color target into coordinates of a screen coordinate system and transmits effective position information and control information to a computer device of a screen through a communication interface. Correspondingly, the invention furthermore discloses an interactive electronic whiteboard system. By implementing the method, accurate and reliable contact or non-contact type positioning can be realized, and the problems of high cost, large size limitation, relatively large volume and the like of an electronic whiteboard interaction apparatus can be solved.

Description

Technical field [0001] The invention relates to the field of electronic whiteboards, in particular to a human-computer interaction method based on binocular stereo vision, and an electronic whiteboard system based on the method. Background technique [0002] The interactive electronic whiteboard system expands and enriches the functions of traditional computer multimedia tools, improves the audio-visual effect, and can flexibly and conveniently edit, annotate, and manipulate the multimedia content displayed on the electronic whiteboard, realizing interactive teaching and learning in the true sense. Display mode. Therefore, the interactive whiteboard system is widely used in office meetings, teaching, lectures, conferences and other occasions. [0003] Human-computer interaction is an important part of the interactive electronic whiteboard system. The existing interaction methods mainly include capacitive screen, infrared, CCD optical, etc. The principle of infrared is to come thr...
