Summary:The oblique photography technology can achieve the construction of three-dimensional models of real scenes. However, the individual building objects are unable to be automatically identified from the 3D city model which is exported as a continuous triangular irregular network (TIN). In this paper, a vector monomerization method is proposed to extract and monomerize the 3D building model based on the DSM model. The algorithm consists of the region segmentation, the contour tracking and optimization. Besides, traditional Cesium open-source platform is improved by integration the proposed method to monomerize and visualize the 3D models. The experimental results show that the proposed method can realize automatic monomerization of the oblique photography model dynamically, and improves the traditional manual monomerization operation on the cesium platform.
