桩基钻孔测量仪立体图形显示的实现

The Realization of Three-dimensional Displaying for Shaft Measuring Instrument

本文利用最小二乘法对计算机采集的横断面超声测距数据进行了拟合处理 ,给出了相应的算法 ,绘出了井筒横断面的形状。利用井筒的不同横断面的形状数据 ,建立了井筒立体显示的数学模型 ,用 MATL AB实现了井筒形状的立体显示。

This paper presents a data processing algorithm by least square criterion to deal with the ultrasonic distance measurement data collected by computer. The plane figure of the transect of the shaft is available. The mathematics model of three dimension figure displaying for shaft is established by means of the plane figure data of different transects. At last, the solid shaft figure displaying is realized by MATLAB.
