面向基站线束设备的无标志AR布线指导系统构建

Construction of markerless-AR wiring guidance system for base station wiring harness equipment

为了提高布线效率、保障装配质量,利用增强现实(AR)技术对基站线束设备进行辅助布线。针对线束设备三维注册范围需求大的问题,系统设计架设头顶摄像头,将基于人工标志物与自然特征点的视觉跟踪算法集成入框架,实现对操作载体和线束设备的动态跟踪,数据通信协同实现多坐标系转换,完成大范围的注册配准。同时为了减少人工标志造成额外信息干扰,初始化注册完成后,利用实时感知场景的同步定位与地图构建(SLAM)技术和空间锚技术实现虚拟模型在混合场景的位置保持,简化注册步骤,缩短注册时间,达到无标志目的。

In order to improve the wiring efficiency and ensure the assembly quality,augmented reality(AR)technology is used to assist the wiring of the base station(BS)wiring harness equipment.Aiming at the problem of large demand for the 3D registration range of wire harness equipment,the system is designed to set up the overhead camera,integrate the visual tracking algorithm based on artificial markers and natural feature points into the system framework,realize the dynamic tracking of operation carrier and wire harness equipment,and realize multicoordinate system transformation of data communication coordination.Multi-coordinate system conversion completes a wide range of registration.In order to reduce the additional information interference caused by the artificial marker,after the initial registration is completed,the simultaneous localization and mapping(SLAM)technology and the spatial anchor technology of the real-time perception scene are used to realize the position of the virtual model in the hybrid scene,which simplifies the registration procedure,shortens the registration time,and achieves no-marker purpose.
