Abstract
The application discloses a few-shot three-dimensional reconstruction method and device based on a neural radiance field and semantic segmentation, and the method comprises the following steps: training the neural radiance field based on semantic loss, adjacent semantic loss, random adjacent semantic loss, color loss and texture loss; and reconstructing a test picture based on the trained neural radiance field to obtain a reconstruction result of the test picture. The present application can correct the reconstruction process and bring as few fine-grained constraints as possible, avoid inaccurate prior knowledge from bringing wrong guidance, and thus achieve better reconstruction quality.
