摘要：根据"立竿见影"现象及竿影日照图的原理,分析影子的形成原理和影子随时间的变化规律,建立了时间、太阳位置和影子轨迹关系的数学模型,利用影子轨迹图分别推导出求解建筑物朝向、间距、采光时间的数学公式。设计算法通过Visual Basic和Visual Lisp编程,研制计算机反求实验平台,构建利用竿影轨迹图反求建筑采光效果的方法。
According to the natural phenomenon that produces a shadow of objects under direct sunlight,the formation principle of stick sunlight shadow chart was studied. Analyzing shadow variation with time,the mathematical model of time,solar position and shadow track was built.The equation of building towards,space,and lighting time were derived using shadow track chart.The computer experiment platform of reverse was developed by programming Visual Basic and Visual Lisp realizing reverse algorithm.Finally,a reverse method of the effect of building lighting based on stick sunlight shadow chart is constructed.
