Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent teaching, and in particular relates to a video display stand based on a wireless intelligent interactive system. Background Art

[0002] The main function of the video display stand is to convert information such as physical objects, documents, pictures and processes into image signals, and output them to display devices such as projectors, monitors or displays through CCD cameras, so that more relevant personnel can browse the information and interact with each other on the information.

[0003] With the improvement and perfection of the wireless intelligent interactive system, R&D personnel combined the video display stand with the wireless intelligent interactive system to facilitate remote interactive teaching, thus solving the problem of being unable to communicate and learn on site due to long distances.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing intelligent interactive video display stand, during use, the presenter places the object on the support platform, controls the camera to shoot the object, and transmits the shooting content to the display screen through the Internet of Things for display. However, since the lower surface of the object is in contact with the support platform, it is inconvenient for the camera to shoot the lower surface of the object, which makes the object display incomplete, thereby reducing the display effect of the object, and further affecting the quality of interactive teaching between the later viewers and the presenter about the object;

[0006] 2. In the existing intelligent interactive video display stand, during use, the presenter manually adjusts the orientation of the object on the support platform, and then uses video to display different surfaces of the object. However, the presenter needs to repeatedly adjust the orientation of the object, which increases the presenter's workload and is inconvenient to display the object at different positions and interact with the viewer about the object.

[0007] To this end, we provide a video display stand based on a wireless intelligent interactive system to solve the above problems. Utility Model Content
