面向全息实景地理环境的特色建筑增强显示方法研究

Research on Enhanced Display Methods for Characteristic Buildings in Holographic Real-Scene Geographic Environments

摘要: 目的：针对全息实景地理环境中特色建筑轮廓不突出、群体边界不清和视觉重点不明确等问题，提出面向建筑类型与场景特征的增强显示方法。方法：将特色建筑划分为单体和群体两类，结合视觉认知、格式塔心理学和地图学综合理论，构建单体轮廓强化、群体边界强化和场景层次引导策略，并引入视点距离、目标屏幕占比和背景复杂度等参数进行控制。结果：典型场景分析和用户实验表明，增强显示可缩短任务完成时间、提高识别准确率，并改善清晰度和视觉聚焦评价。结论：该方法可在保持场景真实感的基础上提升特色建筑辨识度和重点表达效果。

Abstract: Objective: To address unclear outlines, indistinct group boundaries, and weak visual focus of characteristic buildings in holographic real-scene geographic environments, this study proposes an enhanced display method oriented to building types and scene characteristics. Methods: Characteristic buildings are classified into individual buildings and building groups. Based on visual cognition, Gestalt psychology, and cartographic generalization, strategies for individual outline enhancement, group boundary enhancement, and scene hierarchy guidance are constructed, and parameters such as viewpoint distance, target screen proportion, and background complexity are introduced for control. Results: Typical scene analysis and user experiments show that enhanced display can shorten task completion time, improve recognition accuracy, and improve the evaluations of clarity and visual focus. Conclusion: The method can improve the recognizability and key expression effect of characteristic buildings while maintaining scene realism.
