The invention provides a
scene segmentation and editing method and
system based on three-dimensional
Gaussian sputtering, and the method comprises the steps: carrying out the two-dimensional instance segmentation of a three-dimensional scene multi-view two-dimensional image, obtaining a two-dimensional instance
mask, initializing the three-dimensional reconstruction through three-dimensional
Gaussian sputtering, and obtaining a three-dimensional
Gaussian body set; associating cross-view consistent semantic features extracted by the pre-training visual
language model for each Gaussian body, constructing and iterating a three-dimensional instance prototype
library based on a two-dimensional instance
mask, and performing conversion to obtain a cross-view consistent two-dimensional supervision
signal; adding a learnable instance identity code for each Gaussian body, constructing a multi-dimensional
loss function in combination with a two-dimensional supervision
signal, a spatial neighborhood relationship and cross-view consistent semantic features, and optimizing learnable parameters containing the instance identity codes; and realizing Gaussian body instance grouping based on the optimized instance identity codes to complete instance-level
scene segmentation and editing. According to the method, the technical problems of instance identity association and high-quality instance level generation under the conditions of sparse
view angle and close adjacent objects are solved.
