摘要
为探究解决AR Maps表达中普遍存在的视觉过载问题的方法,基于实景视觉信息量提出了一种新的面向交通应用场景的AR Maps载负量计算方法;以此为基础提出了AR Maps多尺度显示模型构建方法,建立了AR Maps多尺度显示模型;根据此模型进行了AR Maps POI标签的显示控制方法的研究;实现了AR Maps原型系统并进行实验。结果表明,在交通应用场景下,AR Maps载负量计算方法和多尺度显示模型可以有效解决AR Maps中存在的视觉过载问题,并具有一定的实用性和可靠性,能够为AR Maps表达的研究提供科学性依据。
In order to solve the problem of visual overload in expression of Augmented Reality Maps, a new AR Maps load calculation method for traffic application scene was proposed based on the real visual information. Based on the method, the method for building the multiscale display model of AR Maps was proposed, and the method was established. The display control method of AR Maps POI tags was studied based on this model. The AR Maps prototype system was implemented and experiments were carried out. The results show that in traffic application scene, AR Maps load calculation method and multiscale display model can effectively solve the problem of visual overload in AR Maps, and have certain practicability and reliability, which can provide scientific basis for the research of AR Maps expression.
