The present invention proposes a method for fast rendering of big data based on a two-way data processing mechanism. The core is to monitor the mouse operation in real time during the parallel execution of the rendering data and the rendering process, update the rendering parameter set and the rendering data set in real time, and based on the current rendering Parameter table, while interactively loading internal and external memory data, according to the current rendering level, query index, and point cloud visibility of different levels, use the N‑LRU mechanism for the data set according to the node layer to screen the cached data; after screening The data is stored in the two-way rendering data cache queue, and the rendering thread continuously reads the current rendering parameter set and rendering data set to be rendered from the two-way rendering data cache queue. The invention creates the two-way data mechanism, improves the efficiency of big data interaction between internal and external storage, refreshes and removes cached data in the memory in real time, reduces memory pressure, and combines the rendering parameter set to rationalize the overall situation and details of point cloud data Efficient display.
Description
technical field [0001] The invention belongs to the technical field of laser point cloud data processing, and in particular relates to a method for fast rendering of big data based on a two-way data processing mechanism. Background technique [0002] At present, the application of laser radar in various industries has gradually matured, and the amount of laser point cloud data generated has increased sharply. Therefore, the subsequent processing and analysis of laser point cloud data puts forward higher requirements for the massive data loading and rendering of the platform. . The storage of spatial data is the basis for its effective management. Compared with two-dimensional data, the storage of three-dimensional irregular data is more complicated, and more factors need to be considered. The current mass of laser point cloud data ranges from more than 100 million points to tens of billions of points. The traditional memory-based data loading can no longer meet the requirem...
