Method for loading massive oblique photography data

The invention discloses a method for loading massive oblique photography data. The method comprises the following steps: step 1, carrying out grid partitioning on the massive oblique photography data;step 2, performing grading processing on blocks, wherein each grade is one or more model files; step 3, combining the models of the first level in all the blocks into a model file; and step 4, generating a data file through the previous step, reading and loading the data file through the data analysis plug-in when the system needs to load the oblique photography data, and finally efficiently loading the massive oblique photography data into the scene. According to the method, the first-level model files in the mass blocks are combined into one model file, so that the efficiency of adding themass oblique photography data into the system is improved, and the memory overhead of the system is reduced. 一种海量倾斜摄影数据的加载方法，包括以下步骤：步骤1，将海量倾斜摄影数据进行网格分块划分；步骤2，把块进行分级处理，每一个级别为一个或多个模型文件；步骤3，将所有块中的第一个级别的模型合并到一个模型文件中；步骤4，通过上一步生成了数据
