Problems solved by technology

There are no related airborne products in China. On the one hand, it is because the resources of the airborne computing platform are limited. On the other hand, because of the large-scale terrain processing, the amount of calculation is huge, and the usual calculation methods are difficult to guarantee real-time performance.

Embodiment Construction

[0024] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Airborne synthetic vision uses terrain data, aircraft position, heading and attitude information, etc., to perform three-dimensional rendering of the flight track, trend vector and surrounding environment, improve the pilot's situational awareness and situational awareness, thereby improving flight safety, and can Reduce the pilot's workload. Usually, the computing resources of the airborne embedded platform are limited, and the graphics processing capability is weaker than that of general consumer electronics. Therefore, it is more difficult to meet the requirement of running a synthetic vision system with high real-time requirements on the resource-constrained embedded platform. By adopting the method, the calculation requirement in the synthetic scen...

Abstract

The invention provides a three-dimensional terrain rendering method used for airborne synthetic vision, and aims at enhancing the rendering efficiency of the synthetic vision operating on the resource-constrained embedded platform, enhancing the real-time performance of the synthetic vision system and also meeting the requirements of airworthiness regulations and advisory notices for the synthetic vision system on the aspect of accuracy and security. Usually the airborne embedded platform has limited computing resource and has weaker graphic processing capacity than that of the common consumer electronics so as to be difficult to operate the synthetic vision system of high real-time requirement on the resource-constrained embedded platform. With application of the method, the computing requirement in the synthetic vision rendering process can be reduced, the terrain rendering efficiency can be enhanced, the computing process can be optimized and the terrain rendering accuracy can also be guaranteed. The test platform verifies that the three-dimensional rendering efficiency can be effectively enhanced by the method.

Description

technical field [0001] The invention belongs to the airborne synthetic visual technology, and relates to a three-dimensional terrain rendering method for the airborne synthetic visual. Background technique [0002] The visual limitation of aircraft pilots is one of the main factors of serious aviation accidents in the world. In order to solve this problem, research institutions of various countries have invested a lot of manpower and material resources in developing new aircraft cockpit display technology. It is against this background that the synthetic vision system came into being. Synthetic vision is a system that uses terrain data, obstacle data, and airport runway data to generate a three-dimensional virtual vision, and integrates the virtual vision with flight instrument information, guidance information, and warning information. It is one of the key components of the new combined display system (SVS, EVS, HUD) required by civil aircraft to improve low visibility ta...
