测绘地理信息

随着汽车智能化技术的不断进步，AR-HUD(augmented reality head-up display)技术因其提供的沉浸式导航体验而日益受到关注。在符号视觉变量经典理论的基础上，深入分析了AR-HUD车载导航地图的内容体系，重点探讨了AR-HUD导航地图符号的视觉变量，涵盖了空间变量、时间变量、语义变量以及交互变量，提出了AR-HUD导航符号动态视觉变量的设计框架，并构建了分层符号体系，以实现导航信息的层次化、差异化展示。通过典型案例验证了所提框架在实际应用中的实用性和有效性，为AR-HUD导航地图符号设计的理论研究提供了新的视角和有价值的参考。

The advancement of automotive intelligent technologies has heightened interest in augmented reality head-up displays(AR-HUD), particularly for their immersive navigation capabilities. Grounded in classical theories of visual variables, this study conducts an in-depth analysis of the content system for AR-HUD in-vehicle navigation maps. Focusing specifically on the visual variables of AR-HUD navigation symbols—encompassing spatial, temporal, semantic, and interactive dimensions—the research establishes a design framework for dynamic visual variables. Furthermore, a hierarchical symbol system is constructed to facilitate layered and differentiated presentation of navigation information. The practicality and effectiveness of the proposed framework are validated through the design and analysis of typical cases. This work provides novel perspectives and valuable references for theoretical research on AR-HUD navigation map symbol design.
