Building Detection


Extraction of building outline polygons

  1. Input aerial photos or satellite images from a single time period to a trained AI model
  2. The AI model judges the area that is considered to be a building from the image and outputs a confidence map (probability image) with a value of 0.0 to 1.0 for each pixel
  3. Binarization + polygonization by threshold for confidence map (probability image)
  4. By shaping the shape of the output polygon, it is finally output as a building polygon
