The invention provides a building three-dimensional model automatic generation method and device using a satellite image, and the method comprises the steps: collecting a satellite image containing a building, and carrying out the preprocessing of the satellite image; carrying out satellite image blocking on the preprocessed satellite image so as to identify a building roof contour; extracting a building body contour of the building based on the preprocessed satellite image; correcting the roof position according to the building roof contour and the building body contour, and calculating the building height; and generating a three-dimensional model of the building by using a three-dimensional reconstruction algorithm according to the corrected roof position and building height. Through the high-precision image recognition and processing technology, automatic recognition of the building roof contour and the building body mapping contour is achieved, the position of the building roof is corrected according to t
