摘　　要：为了提高工程放样的工作效率,提出了一种融合双目视觉和实时动态差分定位技术(RTK)的可视化放样定位系统,主要由双目相机、RTK模块、机械云台、多激光指示器组成.基于双目相机进行目标点距离测量,结合机械云台的角度信息,确定目标的相对位置.利用RTK模块,实时获取自身地理位置信息及航向角,进一步解算目标的绝对位置(经纬度、高程).多激光指示器能标示多点位,同时获取线路的多点位置信息,便于在整体上对工程放样优化和调整.实验结果表明:20米测距范围内,系统目标位置解算误差在20 cm以内,定位方法具有较高精度,符合土方工程等多场景放样需求,能显著提高施工放样的效率.To enhance the efficiency of construction sampling,we develop a Visual Layout and Positioning System which integrates binocular vision and Real-time Dynamic Differential Localization Technology(RTK).The system is mainly composed of binocular camera,RTK module,mechanical gimbal,multi-laser pointer.Using a binocular camera to measure the distance to the target point,combining it with the gimbal rotation angle,the relative position of the target can be determined.The RTK module is used to acquire the device′s geographic location data and heading angle in real-time.This information can be used to determine the absolute position of the target(latitude,longitude,and elevation).The multi-laser pointer is capable of marking multiple points and simultaneously obtaining multi-point positional information of the route,thereby facilitating the optimization and adjustment of construction layout in a holistic manner.The test results indicate that within a range of 20 m,the system′s target position calculation error is within 20 cm.The positioning method exhibits high accuracy,meeting the staking out requirements for various scenarios such as earthworks,can significantly improve the efficiency of construction layout.
