摘　　要：移动互联网的发展给基于位置的服务(LBS)带来了广泛的应用前景,智能手机的普及使用户定位和获取LBS变得更加方便。目前,手机定位技术特别是室内定位,仍不够成熟,已经成为制约LBS业务发展的技术瓶颈。本文在研究定位技术现状和发展趋势的基础上,提出一种新的室内定位方法,依靠智能手机内置传感器进行图像特征识别和运动状态检测,即可完成室内环境的准确定位,具有成本低、简单方便、灵活易扩展的优点,能够满足移动LBS业务模式发展需求。Along with the technical progress of the wireless mobile internet,location-based services（LBS） have been developing more rapidly,and the popularity of the smartphone also bring more convenient to access to LBS services for mobile customers.But the mobile position solutions,especially indoor positioning,are still difficult and have become the technical bottleneck.To address the problem of indoor positioning,this paper presents an approach of active indoor positioning that use image feature recognition and motion detection to complete the accurate positioning of the indoor environment based on smartphones built-in sensors only,with the technology advantages of low cost,practicable and flexible frame.
