基于复合模型的家居场景生成方法

Composite Model for Home Furnishing Generation

室内三维场景生成技术近年来已得到广泛应用,但如何高效和自动化地生成场景元素的空间组织,仍然是个具有挑战性的问题.为了在给定的目标空间中快速生成符合日常生活规范的家居场景,提高室内场景建模的效率,该文基于室内设计领域的住宅空间家具配置流程,提出用于布局计算的复合模型,处理场景元素的组织和布局问题.具体地,该复合模型将室内场景中的对象分为代理区域和场景元素两个层次,首先以代理区域为单位,依据人体工程学的布局规则在目标空间中进行自动布局计算,然后通过案例库搜索,在代理区域中适配具体的场景元素,形成完整的家居场景.实验表明,与以家具为个体进行自动布局计算的方法相比,用代理区域代理一组家具进行布局减少了目标空间中参与布局的个体数目,降低了布局复杂度,在相同的运行时间下,能得到更为合理的布局结果.通过基于复合模型的家居场景生成方法,用户只需提供户型结构数据,而无需提前一一指定具体的家居元素,能给用户使用带来较大便利.

Indoor scenes generation technique is widely used in recent years.How to generate spatial organization of scene elements efficiently and automatically is full of challenge.In order to generate indoor scenes which conform to the daily life in the given objective space quickly,and increase the efficiency of interior modeling,the composite model for home furnishing generation was proposed.It is based on furniture configuration process.Specifically,the composite model divided the objects in indoor scenes into two levels,one is named patch,which is a kind of area have a certain residential behavior,the other is named scene element means specific object in the scene.Firstly,the composite model takes patch as a unit,and automatically calculates the layout of patches according to the ergonomic factors by stochastic optimization.Then,it fills appropriate furniture set in the patch by searching in the patch case database,and forms a complete indoor scene.The experimental results show that,comparing to the methods which take furniture as unit to the layout calculation,our method reduces the complexity of layout calculation since the patch representing a set of furniture reduces the number of layout object,and can generate indoor object layout more rational in the same runtime.Through this method,the users only need to provide the room’s floor plan,without appointing the specific scene elements one by one in advance,bringing convenience to users.
