This paper utilizes a Neural Radiance Fields -based method for the 3D reconstruction of hyperspectral images to enhance the 3D reconstruction effect and expand its application areas. Hyperspectral imaging technology provides rich optical information across multiple spectral bands, far exceeding traditional RGB images, and can reveal more material properties of objects. Additionally, hyperspectral images can display more texture information and detailed structures of objects, capturing more high-frequency information, making them more advantageous in 3D reconstruction. This paper proposes a NeRF-based hyperspectral image 3D reconstruction method that learns the 3D spatial density distribution and spectral information of objects through a neural network, achieving high-quality 3D image generation from any viewpoint. This study demonstrates the NeRF-based hyperspectral image 3D reconstruction method, which has broad application prospects in fields such as remote sensing, cultural heritage preservation, and agricultural monitoring. By fully utilizing hyperspectral data, the NeRF model can generate 3D images with richer details and more realistic target objects, expanding the potential for hyperspectral imaging applications in 3D reconstruction. Future research can further optimize NeRF algorithms and models, fully leveraging hyperspectral information features to improve the efficiency and accuracy of 3D reconstruction data processing, meeting more application needs and promoting the development and application of hyperspectral 3D reconstruction technology.
