组合参考框架下场景空间关系的自然语言描述

摘要

In order to solve the nature language description problem in complex scene,a nature language description method of spatial relationship in combination reference framework is proposed. Hierarchy reference object is used to determine combination reference framework and 3D visible range is used to determine combination reference framework and cloud model is used to determine uncertainty direction and 3DRS11 direction relationship model is used to realize the continuous direction relationship description which change with time. At last, simple nature language rule is used to realize the nature language description of spatial relationship. The experiment shows that the way can realize nature language description of complex scene spatial relationship accurately.%针对复杂场景空间关系自然语言描述存在的问题，提出了一种组合参考物框架下空间关系自然语言描述方法。层级参照物的选取方法被用于确定组合参考框架，三维可视域被用于实现三维空间关系的描述，云模型被用于实现不确定方向判定，3DRS11方向关系模型被用于实现随时间变化的方向关系连续的描述。最后，简单的自然语言输出规则被应用，得到空间关系的自然语言描述。实验显示，提出的方法能精准的实现复杂场景的空间位置信息的自然语言描述。
