In recent years, many approaches have been proposed to analyze the affordance of 3D objects and to facilitate the synthesis of aesthetic and realistic indoor scenes. However, how to assess the quality of such synthesized 3D scenes is still a challenging problem. To address this, we present a novel approach through so-called Human-Centric Metrics (HCMs) for quantitatively evaluating the layout quality of certain objects, and thus to facilitate indoor scene synthesis. Our HCMs consider both the human-object factors to assess the functional accessibility of indoor objects, and the human-environment factors to assess the subjective comfort in the scene. Given a 3D scene with arranged furniture objects, our method automatically places human agents and then use HCMs to assess both the object arrangement and indoor environment based on the position/direction of a certain human agent. The conducted user study shows that the assessment capability of HCMs well conforms to the interior design knowledge. We also use the HCMs based assessment results to synthesize 3D indoor scenes by suggesting indoor objects and their layout given an empty room. A series of experimental results and comparisons are presented to validate the usability and effectiveness of our HCMs for virtual scene assessment and synthesis.

近年来，已经提出了许多方法来分析3D对象的承受能力并促进美学和现实室内场景的合成。但是，如何评估这种合成的3D场景的质量仍然是一个具有挑战性的问题。为了解决这个问题，我们通过所谓的以人为中心的度量标准提出了一种新颖的方法（HCM）用于定量评估某些对象的布局质量，从而促进室内场景合成。我们的HCM既考虑人为因素来评估室内对象的功能可及性，又考虑人为环境因素来评估场景中的主观舒适度。给定一个3D场景，其中布置了家具对象，我们的方法会自动放置人员，然后使用HCM根据特定人员的位置/方向评估对象的布置和室内环境。进行的用户研究表明，HCM的评估能力完全符合室内设计知识。我们还使用基于HCM的评估结果，通过在给定空房间的情况下建议室内对象及其布局来合成3D室内场景。
