With the increasing popular of oblique aerial photography technology in 3D digital city con-struction,the automation and production efficiency of 3D model construction have been significantly improved,and how to efficiently visualize a large number of 3D models from oblique photography have become a new topic.This paper studies the technical route of data organization,service release and visualization of 3D models from oblique photography,builds a 3D model management prototype system based on WebGL,and realizes the data format conversion,storage management,efficient sched-uling and real-time visualization of a large number of 3D models.It conducts a visualization experiment to test data through the prototype system.The results showed that the visualization of the system is good,and the system can meet the requirements of rapid visualization.
