In order to construct a high-precision urban three-dimensional model under oblique photogrammetry technology,this paper introduces the related theories of oblique photogrammetry technology,proposes to use the network optimization algorithm to optimize the Mesh three-dimensional model,and compares the details,3D accuracy,horizontal accuracy and vertical accuracy of the model before and after optimization.The results show that the details of the model optimized by the network optimization algorithm are better improved,the features of the ground objects are prominent,and the geometric accuracy of the model is also improved.This method can provide reference for the rapid establishment of high-precision three-dimensional model.
