【摘要】 在用高速摄影研究裂缝扩展规律时,由于曝光量不足或爆破烟雾等原因,照片分辨率较差,很难看清楚裂纹,这对研究爆破裂纹的发展过程造成很大的影响。因此用小波变换图像处理技术对摄影图片进行处理,并用VC++编程和MATLAB软件进行仿真,计算出爆破裂纹的发展速度,这对研究岩石爆破破碎机理具有重大意义。更多还原

【Abstract】 Slow-motion photograph is used to study the rule of blast-induced crack developing. But the images of slow-motion are blurred because of some reasons,such as the blasting smog,which makes a bad influence on the study of crack developing. By use of computer image processing technique and wavelet transform theory,and VC++ program and MATLAB software to handle the slow-motion pictures of explosion,the crack developing velocity of marble under explosion is given based on processed images,which is helpful to the furture study of blast-induced crash mechanism of rock.更多还原
