circle fitting to find damping

通过MATLAB对点云数据生成三维网格,并将三维网格做四边形网格细化处理。其中还有专门生成三维网格点云的MATLAB程序( This example shows how a triangular mesh can be resampled on a meshgrid -generated square grid. We illustrate the usage of both functions gridtrimesh and mxgridtrimesh . These two should produce identical results. Funcion mxgridtrimesh is a compiled MEX function written in C and should quicker than)

在图像检索中需要利用对图像的形状处理，本代码求7个HU不变矩(In image retrieval need to use the shape of the image processing, the code same moment seeking 7 HU)

模拟正弦衍射光栅光强分布，图1中X轴是位置，Y轴是光强，图2，是强度分布(Analog sinusoidal diffraction grating intensity distribution)

测距仪测距的过程中，由于受到仪器本身的系统误差以及外界环境影响，会造成测距精度的下降。为了提高测距的精度，我们需要对测距的结果进行改正，可以分为三种类型的改正：仪器常数的改正、气象改正和倾斜改正。(Rangefinder ranging process, due to systematic errors in the instrument itself and the external influences, ranging accuracy will result in a decline. In order to improve ranging accuracy, we need to correct the results of the distance, can be divided into three types of corrections: the correction instrument constant, meteorological correction and inclination correction.)
