Exchange Data

Common Image Generation Interface is the interface between two real-time communication subsystems. In order to exchange data between control end and rendering end of the scene simulation system, a packaging component based on common image generation interface is proposed in this paper, which is applied to visual simulation of helicopters and fighter. The simulation results show that this method can meet the real-time requirement of visual control system and is valuable in visual simulation of the weapon equipment operational field.

Training Simulation

The traditional submarine voyage training has problems of high cost, long period and high risk. In this paper, a submarine voyage training simulation system was proposed based on virtual reality and submarine control theory. At first, the construction of the system and the functions of modules were described. The coach control system based on digital chart was realized, which can achieve functions of training environment and parameters setting. The model library of virtual ocean scene was built and then the scene was rended by Vega Prime. In order to remedy the deficiency of the network, a DR algorithm was explored, which can satisfy the realtime requirements of scene simulation and achieved the frame alignment between channels and coherence of observers.

Simulation And Evaluation

Considering the characteristics of vision in different luminance levels and the errors of the visual angle restituting, this research obtains a series of simulant scenes and the quantity relations between the luminance of actual scenes and reappearance scenes in the low luminance and weak contrast environment. Finally, carrying the subjective evaluation of these scenes, it obtains the scope of luminance and the quantification relations among these stimulus by statistical analysis. This paper provides theoretical basis for scene simulation and evaluation, and obtain quantitative suggestions for corresponding standards. It has important theory significance and the practical value for landscape lighting planning and design.

Scene Features

Infrared scene simulation is an important issue in the military field. Infrared scene simulation system can reproduce and simulate the infrared radiation characteristics of target and its background. Therefore, the analysis of the infrared radiation of target and scene features is very important for Infrared scene simulation. In this paper, we focus on the calculation and analysis of typical environmental factors of ground targets, including solar radiation, sky atmosphere radiation and ground radiation etc.. We also discuss how to calculate the infrared radiation of target in this paper. The results of this paper will be used for analysis of the infrared radiation and the simulation of the infrared scene of ground targets.

UAV simulative training system can insure the time and effect of training through reducing training cost. Scene simulation system in this paper is the vital component of the system. The comparability to real equipment is the ultimate request to the simulative training system, as to the scene simulation system, the reality and the veracity of changing rule of scene is most important. Simulation systems existing have deficiencies in these parts. Through studying on these aspects, the system in this paper uses DEM data and airscape to display lifelike vision of real terrain, scene drive model is designed to simulate the influence to the scene from the state changing of the flight and vidicon, real-time interconnection is realized.
