Abstract: In this paper,the mathematical model of the vertical lines supported aerial triangulation has been established according to the theory of the vanishing point.Two relative problems,which are the layout of the ground control points and the side-overlap,have been studied in order to reveal the accuracy and the realiability of the vertical lines supported bundle block adjustment.The study and the test results show that the vertical lines could be introduced into the traditional bundle adjustment as additional height control conditions and could reduce the necessary height control points number siginificantly,thus the work presented in this paper provides a new way for the calculation of the aerial triangulation of the aerial imagery over urban areas.
