Device for achieving immersive display as well as synchronous moving of projection picture and blackboard of projector

Abstract

The invention discloses a device for achieving immersive display as well as synchronous moving of a projection picture and a blackboard of a projector, and relates to the technical field of teaching aids, mainly aiming at solving the problem that the projection picture and blackboard content cannot be displayed in an immersive mode in the case that the projection picture cannot simultaneously move along with the blackboard in teaching. According to the device provided by the invention, positions of the blackboard and the projector are measured by virtue of a sensor; positions of the blackboard and the projector as well as a projection position of the projector are respectively controlled by virtue of a blackboard vertical motion and position location control device and a project motion control device, so that the projection picture of the projector is integrated with chalk words written on the blackboard, and subsequently the synchronous moving of the projection picture and the black board and the immersive display are achieved; and a classroom teaching effect is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a device for realizing the immersion display of a projector and the synchronous movement of a projected picture and a blackboard. Background technique [0002] In multimedia teaching, a white curtain is usually installed at the front of the classroom, and the projector projects the picture onto the white curtain. In the actual teaching process, it is often necessary to directly add some explanations, annotations and other content to the projected picture, but the existing devices cannot meet this demand, which undoubtedly affects the teaching efficiency and quality. And in teaching, it may be necessary to move the blackboard. When the projection screen of the projector cannot automatically follow the movement of the blackboard, it is necessary to manually adjust the projector so that the projection screen is consistent with the position of the blackboard, which brings...

Problems solved by technology

In the actual teaching process, it is often necessary to directly add some explanations, annotations and other content to the projected screen, but the existing devices cannot meet this demand, which undoubtedly affects the teaching efficiency and quality

And in teaching, it may be necessary to move the blackboard. When the projection screen of the projector cannot automatically follow the movement of the blackboard, it is necessary to manually adjust the projector so that the projection screen is consistent with the position of the blackboard, which brings great benefits to the teaching work. no small trouble
