【摘要】 为了有效地配置温室补光光源以及光强大小,在对温室结构进行一定的模型简化后,提出一种室内人工光照动态覆盖的算法。该算法根据光线追踪理论和有关光学原理建立光线传播树,并通过可视化方法在计算机上对光线照射到的区域进行仿真。通过计算机辅助设计,根据光源在室内所处的不同位置以及光强大小的变化,可以动态显示光线所覆盖到的不同区域。更多还原

【Abstract】 upplemental artificial light influences greatly the normal growth of crops in greenhouse,in order to collocate the lights and its power,the algorithm of dynamic covering area of artificial light is presented after simplifying the structure of greenhouse.A light tracing tree(LTT) can be set up according to the light tracing theory and the covering area can be simulated using the information saved in the nodes of the LTT.Through computer aided design,different covering area can be displayed whenever the power of the light and its position is changed.更多还原
