Description

Technical Field

[0001] The utility model relates to the technical field of popular science education, in particular to a three-dimensional imaging popular science teaching aid. Background Art

[0002] Popular science teaching aids are tools used for education and learning. They aim to help students gain an in-depth understanding of scientific principles and technological applications through observation, operation, and experience. Optical and physical experimental equipment help students learn optical and physical knowledge, biology teaching aids help students understand biological principles, chemistry teaching aids stimulate students' interest in chemistry, and geography teaching aids cultivate hands-on ability and innovative thinking. These teaching aids not only help students learn scientific knowledge, but also cultivate their hands-on ability and innovative thinking during the operation process.

[0003] ‌Three-dimensional imaging popular science teaching aids are tools used to educate and demonstrate three-dimensional imaging technology. They aim to demonstrate optical principles and three-dimensional imaging technology to students and the public in an intuitive way. These teaching aids usually combine optical principles and use the interference and diffraction of light to achieve the display of three-dimensional stereo images. The implementation principle of three-dimensional imaging popular science teaching aids mainly relies on the interference and diffraction of light. First, the object's light wave information is recorded through the interference principle, that is, the shooting process, and the contrast and interval between the interference fringes are used to record all the information of the object's light wave. Then, the object's light wave information is reproduced through the diffraction principle to form a three-dimensional image with a real dimensional space. This technology can not only be demonstrated in the classroom, but also used for museum exhibits to provide high-contrast and clear three-dimensional stereo images.

[0004] 3D holographic imaging equipment has the advantages of flexible size, easy installation and diverse content. The hardware equipment is divided into two parts: imaging area and working area. Different sizes can be selected according to different application requirements. The hardware system and structure can be modified according to the existing building and installation location space, which is convenient for use in different environments. However, the stability of the image directly affects the accuracy of subsequent image matching and depth calculation. During the shooting process, human shaking and external vibrations will cause image jitter. Severe image jitter will lead to matching errors, thereby affecting the effect of 3D reconstruction.
