data reduction error的意思|示意

Flow field calibration error will effect the uncertainty of the experimental data through data reduction process.

风洞流场校测误差通过试验数据处理而影响试验数据的不确定度。

The NURBS curve is used for fitting the screw profile when cloud datas pretreatment is already done such as eliminated noise data and data reduction, the fitting error is also analyzed.

通过对测量数据的噪声点过滤，数据精简等预处理，采用NURBS曲线拟合螺杆型线并分析了其拟合误差。

Then a feature based polyhedral model is reconstructed adaptively, so a large scale precise data reduction, under allowable error, is also realized at the same time.

在此基础上，完成了基于特征的曲面网格自适应构造，实现了大规模点云的精确数据压缩。
