【摘要】：目前,灰色模型在變形監(jiān)測(cè)數(shù)據(jù)處理及預(yù)報(bào)中的應(yīng)用越來(lái)越廣泛。針對(duì)系數(shù)矩陣和預(yù)測(cè)值存在的誤差,該文采用整體最小二乘法,結(jié)合黑龍江省農(nóng)業(yè)科學(xué)院在江北科技創(chuàng)新城核心區(qū)建設(shè)的國(guó)際農(nóng)業(yè)科技創(chuàng)新中心工程,選取其中一個(gè)沉降監(jiān)測(cè)點(diǎn)進(jìn)行分析。實(shí)驗(yàn)結(jié)果表明,該方法的擬合精度更高,適用于變形監(jiān)測(cè)數(shù)據(jù)處理。
[Abstract]:At present, grey model is more and more widely used in data processing and prediction of deformation monitoring. Aiming at the error of coefficient matrix and prediction value, this paper adopts the integral least square method and combines with the construction of the International Center of Agricultural Science and Technology Innovation Center of Heilongjiang Academy of Agricultural Sciences in the core area of Jiangbei Science and Technology Innovation City. One of the settlement monitoring points is selected for analysis. The experimental results show that this method is more accurate and suitable for deformation monitoring data processing.
