基于车位编码识别的车库行车定位与导航方法
|
摘要
针对从出发点到室内停车位,特别是室内行车时的定位与导航问题,提出了一种依靠车载摄像头识别车库内车位编号,并配合车库电子地图实现车库内车辆定位与导航。该方法整合并延伸了现有移动定位导航功能,首先以车辆入口位置为触发点结束卫星导航并自动切换为对应车库的室内导航模式,然后启用车载摄像头动态识别车位编码并结合车库地图确定当前位置和行车方向,最后通过计算路径可靠度推荐最佳路径。实验使用visual studio(VS)编程识别车位编码,通过与车库电子地图匹配完成定位,以实拍车库车位编码进行验证,可以做到准确识别、快速定位。提出的基于车位编号识别的车辆定位导航方法实现了与卫星定位系统的衔接导航,提高了规模化的大型地下车库的服务效率,填补了室内外端对端导航的空白,对室内定位导航方面的研究有良好的支撑。
From the point of departure to the indoor parking space,especially the location and navigation problems in indoor driving,a vehicle parking camera recognition of the parking lot number in the garage,and coordinates with the garage electronic map to achieve vehicle location and navigation in the garage is proposed. This method integrates and extends the existing mobile positioning and navigation functions. Firstly,the satellite navigation is terminated at the entrance of the vehicle as the trigger point,and the indoor navigation mode is automatically switched to the corresponding garage. Then,the dynamic recognition of the parking space code by the vehicle camera and the direction of the vehicle are determined by the garage map. Finally,the optimal path is recommended by calculating the reliability of the path. The experiment uses visual studio( VS) programming to identify the parking code,completes the location through matching with the garage electronic map,and validates the garage parking lot code,so that it can identify and locate quickly. The vehicle navigation method based on the recognition of the number of parking spaces realized Navigation combined with Global Satellite Positioning System and improved the scale of the large underground garage service efficiency,fill the blank on the end of the outer end of indoor navigation,research on indoor positioning navigation has good support.
