Diversity-preserved domain adaptation using text-to-image diffusion for 3d generative model

A three-dimensional image generation server comprising:

• a memory storing a program for performing a domain adaptable three-dimensional image generation method;
• and
• a processor configured to execute the program,
• wherein the processor includes:
• a target image generation unit configured to generate N target images corresponding to a second domain by converting styles of previously collected N source images corresponding to a first domain according to instructions of an input text,
• a target image filtering unit configured to select only a target image that satisfies a preset condition among the N target images, and
• a domain adaptation unit configured to generating multiple three-dimensional images corresponding to a specific domain through certain noise data and a preset camera pose parameter by training a three-dimensional generation model, which is previously built, by using the selected target image, and
• wherein the N source images and the N target images are three-dimensional images each composed of multiple camera viewpoints, and
• each of the N target images is converted to an image of at least one style set in the second domain while maintaining an object included in each of the N source images.
