This paper presents a new method for the site modeling from aerial image data. Initially 3D lines are extracted by using elevation data obtained by area-based stereo. The grouping process is implemented by using centroid neural network algorithm to classify 3D lines into groups of lines. Using grouped 3D lines, hypothesis selection is carried out based on(More)
Building reconstruction from aerial image data has been studied in this paper. 3D line segments generated by using stereo image analysis are usually fragmented, and it is very hard to reconstruct building rooftop from segmented 3D lines. Centroid neural network algorithm is employed to classify 3D lines into groups of lines. With this grouping technology,(More)
