空间能力驱动的三维产权体空间可视化

法律支持的三维产权空间是市民的空间权益核心，产权体的权属边界、空间位置和周边关系是用户关注的重点。数字城市可视化可实现对建筑外表的逼真模拟，但是产权空间与实体空间既有关联又存在差异，如何构建符合认知习惯且有效传达空间信息的三维可视化成为难题。本项目基于空间认知研究三维场景和产权体可视化，从人的空间旋转能力、抽象推理能力、视觉感知能力、环境认知能力等基本空间能力出发，探寻三维可视化认知驱动因素，研究它们与三维形体、城市空间环境之间的相关性；以三维产权体可视化为例，构建“第一眼”可视的焦点可视化技术提高显著性，利用眼动实验探索不同位置（地上VS地下、外表VS内里）、不同形态（方形VS异形）、不同权属的可视化方法和认知效应，分析和计算视点从焦点对象到群集和背景的过渡、转移，解析焦点产权体与群集背景的空间关系和空间布局，改善房地产产权可视化策略，指导三维电子产权证的设计，支持三维产权管理系统。

3D property units with legal permit are the core of spatial interests cared by the citizens, and spatial boundaries and context relationships are focused and cared by the citizens during their visualization. How construct cognition-adapted visualization to convey property information become a challenge. The methodology and techniques about visualization need to meet the requirements from 2D map to 3D geo-environment. The visualization about 3D property unit differs from the building visualization focusing the appearance and textures of the buildings. The visualization about 3D property units and their set pay more attention on their boundaries, shapes and locations. This research integrate the 3D geographic visualization with cognitive psychology to explore the correlations between spatial cognition and 3D property’s prominence under 3D geo-visualization. From the perspectives of mental rotation ability, spatial reasoning ability, memory ability, spatial perception ability and spatial positioning ability, cognition-driven factors for 3D property unit visualization are analysed, and the relations between the five abilities and 3D shapes, urban environment. Taking 3D property units and its coherent set as examples, this research builds focu-visualization with "first sight" to enhance the prominence and significance of 3D property unit. Eye-tracing techniques are used to test user’s visualization and behaviors for 3D property unit sets in different environment, especially different locations (above earth surface VS under earth surface), different shapes for 3D property units (rectangle VS heteromorphism), different ownership rights. This research would analyse the sight attention transition from the focused unit to the context units, which can help to understand the information about the focus object and its relationship under the context to promote the visualization strategy for real estate visualization. This project will enhance the efficiency of the recognition and object-finding of 3D focus object in 3D geographic environment to conduct the design of 3D visualiztion system and digital property identifier.
