摘要
信息扩散估计技术被应用到水准网平差这一多维参数估计中,部分地解决了在测量数据处理中的应用问题。在此基础上,将多参数的信息扩散估计进一步推广到导线网平差中,并通过实例计算与传统预测方法进行了比较,结果表明,该方法具有较高的精度和推广应用价值。
The Information Spread Estimation is extended to the level network adjustment.The solution to the measurement data processing is partly solved.On this basis,multi-parameter information spread estimation was further promoted to the lead network adjustment.Through the example calculation with the traditional forecasting methods were compared,the results showed that the method had high accuracy and application value.
