Multi-view height estimation from satellite images

A system for computing a height of a structure, said system comprising:

• a processing computer configured to
• input a pair of first and second two-dimensional (2-D) aerial images taken from a camera from different perspectives along with metadata for each image, each image including at least said structure;
• compute, for each image, using said metadata, a three-dimensional (3-D) vector from a geo-referenced location of said each image on a ground plane of the Earth toward d the location of said camera when said each image was taken with said camera;
• compute a plurality of pairs of coordinates of corresponding first and second image points from said geo-referenced locations of said images, wherein in each pair of image points a first image point of said first image identifies the same physical point on said structure as a second image point of said second image;
• for each pair of image points, determine the intersection of said 3-D vector of said first image originating at the coordinates of said first image point with said 3-D vector of said second image originating at the coordinates of said second image point, wherein said each intersection being a 3-D position;
• and
• determine said height by taking a median of said 3-D positions and output a height of said structure based upon said 3-D positions.
