摘　　要：定点测绘数据往往受到通信距离、传输速率和数据安全等方面的限制,导致单位周期内传输的数据量较小,因此设计一种基于光纤通信网络的定点测绘数据实时采集方法。将定点测绘数据稀疏表示,以便更有效地进行数据压缩感知。构建定点测绘数据的观测矩阵,实时传输这些数据。最后,建立压缩感知的数据采集框架,实现定点测绘数据的实时采集。实验结果表明,该文方法设计的基于光纤通信网络的定点测绘数据实时采集方法,单位周期内传输的数据量较大,最大达到49GB,证明该方法数据输出稳定,数据采集的效果更好。Fixed point surveying data is often limited by communication distance,transmission rate,and data security,resulting in a small amount of data transmitted per unit cycle.Therefore,a real-time collection method for fixed point surveying data based on fiber optic communication network is designed.Sparse representation of fixed-point surveying data for more effective data compression perception.Construct an observation matrix for fixed-point surveying data and transmit this data in real-time.Finally,establish a compressed sensing data collection framework to achieve real-time collection of fixed-point surveying data.The experimental results show that the real-timc data collection method for fixed-point surveying and mapping based on fiber optic communication network designed in this paper can transmit a large amount of data per unit cycle,with a maximum of 49GB,proving that the data output of this method is stable and the data collection effcct is bettcr.
