Abstract
In one aspect, a computerized method to automatically detect buildings includes determining if each point of a set of filtered points is on a line by processing the set of filtered points in one pass including a) locating a first point of the set of filter points nearest to a second point of the set of filtered points, b) determining if the distance between the first point and the second point is greater than a distance threshold; c) determining if the first point and the second point have collinearity greater than a collinearity threshold; and d) designating the first point as an endpoint of a line that includes the second point if the distance between the first point and the second point is greater than the distance threshold and if the first point and the second point have collinearity greater than the collinearity threshold.
