摘　　要：介绍了一种在MATLAB中实现三维表面非均布测量数据可视化的方法。对于三维表面的非均布测量数据,利用MATLAB的有关函数,确定出均布的坐标点,通过拟合、插值获得均布坐标点处的高度坐标值,实现了将非均布测量数据转换为均布测量数据,并利用MATLAB提供的三维可视化函数实现可视化。A kind of method to achieve visualization of non-uniformly distributed measuring data of 3D surface in MATLAB environment was introduced. Using associated functions supplied by MATLAB, uniformly-distributed coordinates were determined according to raw data. height coordinates at each uniformly-distributed coordinates were calculated out by means of fitting and interpolation, non-uniformly sampled measuring data was transformed to uniformly distributed data, and visualization was achieved using 3D visualization functions supplied by MATLAB.
