【摘要】：场景识别是室内外无缝定位技术的研究重点,场景识别的好坏决定了位置服务用户体验的优劣,已有室内外场景识别研究方法存在数据冗余和计算复杂度高的问题。鉴于此,该文提出一种基于手机端的室内外场景识别方法,利用智能手机获取GPS卫星高度角、信噪比和卫星数目,通过分析上述实验数据的相互作用影响,得到基于截止高度角、信噪比阈值和GPS卫星数目阈值的室外到室内场景识别判定依据,实验证明,该判定依据可有效区分室外、室外到室内过渡区域和室内场景。为得到普适的室内外场景识别方法,该判定依据需在其他场景进一步验证。
[Abstract]:Scene recognition is the research focus of indoor and outdoor seamless location technology. The quality of scene recognition determines the advantages and disadvantages of location service user experience. The existing research methods of indoor and outdoor scene recognition have some problems such as data redundancy and high computational complexity. In view of this, an indoor and outdoor scene recognition method based on mobile phone is proposed in this paper. The height angle, signal-to-noise ratio and the number of satellites of GPS satellite are obtained by using smart phone, and the interaction effect of the above experimental data is analyzed. Based on the cut-off angle, signal-to-noise threshold and the threshold of the number of GPS satellites, the identification criterion of outdoor-to-indoor scene is obtained. The experimental results show that the criterion can effectively distinguish outdoor, outdoor-to-indoor transition area and indoor scene. In order to obtain the universal method of indoor and outdoor scene recognition, the basis of this decision needs to be further verified in other scenarios.
