Title:
SYSTEMS AND METHODS FOR CONSTRUCTING A BUILDING BLOCK MODEL
Document Type and Number:
WIPO Patent Application WO/2022/105604
Kind Code:
A1
Abstract:
The present disclosure provides a method for constructing a building block model. The method may include obtaining a remote sensing image. The method may include obtaining a processing result by processing the remote sensing image using an image processing model. The processing result may include a segmentation result of a top surface of a building in the remote sensing image and feature information of pixels representing the building in the remote sensing image. The method may further include determining a bottom surface of the building in the remote sensing image based on the processing result. The method may further include determining a height of the building in the remote sensing image based on the feature information of the pixels representing the building. The method may further include constructing the building block model based on the bottom surface of the building and the height of the building.
