It is a serious island problem in the information technology of construction industry. So automatic recognition and 3D reconstruction on architecture structure drawings are quite important to improve the state. Because of the speciality of the architecture field , research on the buildings’3D reconstruction is still little , and researchers in this field are few. This paper analyses the distribution and variety of the buildings’3D information which are based on the new criterions of plane-based representation in China and are the main difficulti
