Apparatus and method for generating standardized 3d objects based on satellite imagery

A method for generating standardized 3D objects based on satellite imagery, the

• method comprising:
• preprocessing the satellite imagery by upscaling the satellite imagery using a generative adversarial network (GAN), and then resizing and dividing the upscaled satellite imagery;
• generating a digital surface model for the preprocessed satellite imagery by applying a vision transformer to the preprocessed satellite imagery;
• generating boundary information of individual objects included in the preprocessed satellite imagery using a convolutional neural network (CNN);
• and
• generating digital surface models for one or more individual objects included in the preprocessed satellite imagery by combining the digital surface model for the preprocessed satellite imagery with the boundary information of individual objects, and generating a clustered object digital surface model by integrating the digital surface models for the one or more individual objects.

An apparatus for generating standardized 3D objects based on satellite imagery, the apparatus comprising:

• a memory having instructions stored thereon;
• and
• a processor configured to, when executing the instructions,
• preprocess the satellite imagery by upscaling the satellite imagery using a generative adversarial network (GAN), and then resizing and dividing the upscaled satellite imagery;
• generate a digital surface model for the preprocessed satellite imagery by applying a vision transformer to the preprocessed satellite imagery;
• generate boundary information of individual objects included in the preprocessed satellite imagery using a convolutional neural network (CNN);
• and
• generate digital surface models for one or more individual objects included in the preprocessed satellite imagery by combining the digital surface model for the preprocessed satellite imagery with the boundary information of individual objects, and generate a clustered object digital surface model by integrating the digital surface models for the one or more individual objects.
