传统的实时高精度地形三维数据获取方法得到数据精度较差,不能满足研究的要求。设计基于定位系统的实时高精度地形三维数据获取方法。采用北斗卫星定位系统获取地形数据,引用DTM模型构建地形三维可视化模型。使用模糊误差算法剔除地形数据误差。设定数据实时传输约束条件,并引用WebSocket技术,实现实时高精度地形三维数据获取,完成高精度地形三维数据的获取。实验结果表明,此方法数据精度高于原有方法。

The traditional real-time high-precision terrain 3D data acquisition method has poor accuracy,which can not meet the research requirements.A real-time and high-precision terrain 3D data acquisition method based on positioning system is designed.Beidou satellite positioning system is used to obtain terrain data,and DTM model is used to build 3D terrain visualization model.The fuzzy error algorithm is used to eliminate the terrain data error.Set the constraints of data real-time transmission,and use websocket technology to achieve real-time high-precision terrain 3D data acquisition,complete the acquisition of high-precision terrain 3D data.The experimental results show that the data accuracy of this method is higher than that of the original method.
