AI Technical Summary

Technical Problem

Traditional fill lights have poor position adjustment capabilities on document cameras, resulting in blind spots and overexposed areas, which affect the image quality of image acquisition equipment, especially when processing planar materials.

Method used

A demonstration aid device for smart classrooms was designed, including a locking ring, a support plate, and a supplementary lighting component. It is detachably connected to the lens of an image acquisition device via a connecting sleeve. The support frame and the support shaft are adjustable by sliding and rotating to ensure that the light accurately illuminates the image acquisition area and avoids blind spots. The component is prevented from detaching by a limiting ring and a positioning groove.

Benefits of technology

It enables flexible adjustment of the supplementary lighting components, avoiding blind spots and overexposed areas, and improving the image acquisition quality of the image acquisition device, especially the clarity of documents.

Abstract

The utility model provides a demonstration auxiliary device for an intelligent classroom. The demonstration auxiliary device comprises a locking ring, a bearing plate and two light supplementing assemblies. The locking ring is detachably arranged on a lens of the image acquisition equipment in a sleeving manner, an assembling hole is formed in the bearing plate, a rotatable connecting sleeve is arranged in the assembling hole, and the bearing plate is detachably connected with the locking ring through the connecting sleeve. The two light supplementing assemblies are arranged on the two sides of the bearing plate in a mirror image mode, and each light supplementing assembly comprises a supporting frame and a bearing shaft. A containing hole is formed in the side wall of the bearing plate, one end of the supporting frame is arranged in the containing hole in a sliding mode, the other end of the supporting frame is rotationally connected with the bearing shaft, and a light supplementing lamp strip is arranged on the side wall of the bearing shaft. According to the demonstration auxiliary device for the intelligent classroom, the position of a light source can be flexibly adjusted, and illumination dead angles or overexposure areas are prevented from occurring during image acquisition.
