光线跟踪方法实现红外视景成像仿真系统 总被引:1,自引:0,他引:1
简要介绍了红外场景仿真工作中所设计和开发的,用于固定几何形状场景的红外成像仿真系统的基本结构,各个模块的基本功能以及它们之间的相互关系。针对红外成像仿真中与可见光成像的不同的地方作了详细的介绍和分析,展示了仿真的结果并分析了红外成像仿真在红外图像分析和算法研究上所能起到的重要作用。将传统的光线跟踪方法应用到红外成像仿真中,针对红外成像的特性,实现了相应的红外成像渲染器。从渲染结果上看,光线跟踪方法是生成强真实感的红外图像,实现红外成像仿真的一种有效方法。 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献

This paper presents an outline of an Oriental systems methodology: the Wuli Shili Renli approach (WSR). The basic theme of WSR contends that wuli (regularities in objective existence), shili (ways of seeing and doing), and renli (patterns underlying human relations) constitute a differentiated whole that conditions systems projects. WSR suggests that we should design and employ appropriate methods to address and tackle wuli shili and renli elements in a theoretically informed and systemic way. The background, philosophy, process, principles, and some practical applications of the methodology are preliminarily outlined. 相似文献
