Non-contact interactive electronic sand table and working method

Abstract

The invention relates to a non-contact interactive electronic sand table and a working method. The non-contact interactive electronic sand table comprises a pointing object, a camera, an entity sand table, a laser pen, a processor and a multimedia player; the pointing object is a hand or a long strip, and the long strip is an object with a certain length; and the coordinates of each region of theentity sand table are matched with audio and video information in advance. The non-contact interactive electronic sand table and the working method in the invention have the beneficial effects that the problem that entity information cannot be obtained by touching an entity model with the hand when the sand table model is large or is isolated with glass is solved; the camera performs monitoring and video image acquisition on the sand table model and can process a video image to obtain the coordinates of a point where the pointing object extension direction intersects with the surface of the entity model when a user uses a strip-shaped object such as a hand or a stick to point to the entity sand table model, so that the media player can match the corresponding audio and video data information according to the coordinates, further, the media player can play the corresponding audio and video, and the interaction with the entity model is realized.

Description

technical field [0001] The invention relates to the field of electronic sand tables, and particularly includes a non-contact interactive electronic sand table and a working method. Background technique [0002] Through the sand table, buildings and terrain can be simulated vividly, so the sand table is often used in military command and teaching. [0003] At present, the main use scenario of the electronic sand table is to obtain audio and video explanations by touching specific positions of the sand table model with hands. However, when the sand table model is large or is isolated by glass, it is impossible to obtain physical information by touching the physical model. [0004] Therefore, it is particularly important to propose a non-contact interactive electronic sand table and working method. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a non-contact interactive electronic sand tab...
