METHOD FOR 3D RECONSTRUCTION FROM SATELLITE IMAGERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20230186561 titled 'METHOD FOR 3D RECONSTRUCTION FROM SATELLITE IMAGERY

Simplified Explanation

The present disclosure describes a method for reconstructing 3D models from satellite images using deep learning. The method involves using overlapping 2D satellite images and their corresponding imaging device parameters. A trained machine learning network (MLN) is used to predict depth maps based on a training set of geocoded 3D ground truth data.

  • The method uses at least two overlapping 2D satellite images.
  • The imaging device parameters for the satellite images are provided.
  • A trained machine learning network (MLN) is used to predict depth maps.
  • The MLN is trained on a training set of geocoded 3D ground truth data.
  • The depth map of the provided satellite images is predicted using the trained MLN and imaging device parameters.

Potential applications of this technology:

  • Urban planning and development: The 3D reconstruction can provide valuable information for urban planners and developers to visualize and analyze the environment.
  • Environmental monitoring: The technology can be used to monitor changes in landscapes, vegetation, and natural resources over time.
  • Disaster management: The 3D models can assist in assessing the impact of natural disasters and planning relief efforts.
  • Navigation and mapping: The reconstructed 3D models can be used for accurate navigation and mapping purposes.

Problems solved by this technology:

  • Traditional methods of 3D reconstruction from satellite imagery are often time-consuming and require manual intervention.
  • The use of deep learning and machine learning networks allows for automated and efficient reconstruction of 3D models.
  • The method can handle overlapping satellite images and accurately predict depth maps.

Benefits of this technology:

  • Faster and more efficient 3D reconstruction process compared to traditional methods.
  • Accurate and detailed 3D models can be generated using satellite imagery.
  • The method can handle large datasets and provide consistent results.
  • Automation reduces the need for manual intervention and human error.
