Acceleration Method of Air Traffic Electronic Chart Display Based on CUDA

Abstract

The present invention discloses an air traffic electronic aviation map display acceleration method based on a CUDA. The method comprises the following steps: S1, preprocessing electronic aviation map display elements and carrying out formatting processing; S2, partitioning blocks of the electronic aviation map display elements; S3, calculating required block numbers according to a viewport extent; S4, carrying out multi-block parallel calculation to display element contents; and S5, splicing displaying results of blockettes. Compared with a conventional technical means, the air traffic electronic aviation map display acceleration method based on the CUDA has the outstanding advantages that (1) display interaction efficiency of an air traffic electronic aviation map is greatly improved; (2) the air traffic electronic aviation map display acceleration method can support display of a great volume of electronic aviation map display element data and data increase cannot influence display efficiency of the aviation map; (3) a real-time display effect of the air traffic electronic aviation map can be improved; and (4) the air traffic electronic aviation map display acceleration method provides expanding and promoting abilities for real-time calculation related to a track target in the air traffic electronic aviation map.

Description

technical field [0001] The invention belongs to the technical field of air traffic control systems, in particular to a method for accelerating the display of air traffic electronic charts based on CUDA in the air traffic control system. Background technique [0002] The traditional air traffic electronic chart display method is based on data structures such as points, lines, planes, texts, and pictures, and uses the basic graphics API functions provided by the computer to draw them one by one on the special display screen for air traffic control in the order of graphics superposition and display. When the controller zooms in, zooms out, moves or partially modifies the content of the electronic chart, it is necessary to repeat the above-mentioned large number of sequential drawing tasks. This traditional technology relies heavily on the sequential execution of CPU instructions. When the data size of the electronic air chart is large, the redrawing of the situation scene will ...

Problems solved by technology

This traditional technology relies heavily on the sequential execution of CPU instructions. When the data size of the electronic air chart is large, the redrawing of the situation scene will consume a lot of computing resources, which will cause the system to be slow and unable to respond to the controller's operation instructions in time, and the interactive experience will be great.
