摘要:
The present invention relates to a method for three-dimensional measurement and calculation of the geographic position and height of a target object based on street view images. The method comprises: selecting a target object in a street view map at first and then selecting two appropriate viewpoints according to the target object and obtaining the longitudes and latitudes of the two viewpoints; obtaining three street view images at different viewing angles under the viewpoints respectively; calculating the horizontal angles and pitch angles of the target object under the viewpoints according to the three street view images; determining two spatial straight lines according to the longitudes and latitudes of the viewpoints and the viewing angles from the viewpoints to the bottom of the target object, which intersect forward, and calculating the intersection of the two straight lines, which is the geographic position of the target object.
