图像间距离测量可以轻松实现，还有大量源码可共分享-Measuring the distance between images can be easily achieved, there are a large number of source code can be a total share

matlab与距离保护相结合，采用MATLAB对距离保护配置中的补偿系数进行计算，程序优化简单。-matlab combination with the distance protection using MATLAB distance protection configurations compensation coefficient calculated program optimization simple.

空间插值，样点在预测点值的计算过程中所占权重的大小受参数的影响；也就是说，随着采样点与预测值之间距离的增加，标准样点对预测点影响的权重按指数规律减少。(Spatial interpolation)
