光测力学中图像相关方法在土石中的应用，测量土中的应变场-In PHOTOMECHANICS image correlation method in the debris, measure the strain field in the soil

将采集的土图片载入MATLAB并计算其熵、灰度值等-The images collected soil load and calculate the entropy MATLAB, the gray values, etc.

实现土堤生成:运行后先选择线宽和颜色然后再进行折线绘制 最后生成土堤-Achieve embankment Generation: first the line width and color after running and then to draw a line and finally generate embankment
