| 摘 要： | 根据物体在太阳光照射下将产生影子的自然现象,研究物体影子的形成原理,通过分析物体实形与其影子关系建立数学模型.进一步利用影子的形成原理进行逆向变换,通过Visual Basic和Visual Lisp编程实现反求算法,研制了计算机反求实验平台,实现对影子的反求,并通过实验反求实际模型,比较分析数据误差从而验证算法的有效性,最后提出了一种新的反求方法.

| Abstract: | According to the natural phenomenon that produces a shadow of objects under direct sunlight,the principle of formation of a shadow was studied,through analyzing the relationship between actual shape of objects and its shadow,and then their mathematical model was built.Further using this principle to make reasonable reverse transformation,the computer experiment platform of reverse was developed by programming Visual Basic and Visual Lisp realizing reverse algorithm.The computer experiment platform was appli... |
