摘　　要：在岩块图像分析识别前的预处理工作中,为了平滑岩块图像本身的局部噪点并保护岩块图像的目标区域,对岩块图像二值化分割进行了研究。提出利用ImagePy进行露天爆堆黏连岩块图像预处理的分析方法,明确了露天爆破现场图片采集要点和对小岩块区域变异系数考虑的方式,开发了基于ImagePy的双边滤波器插件,选定(30,11,11)三参数进行双边滤波分析。实例分析证明本方法对露天爆堆岩块图片处理能得到良好的二值化分割效果,同时证明开源图像处理框架ImagePy在爆堆岩块图像预处理具有较好的可行性。In the pretreatment work before the image analysis and identification of rock blocks,in order to smooth the local noise of the rock image and protect the target area in the rock image,the binarization segmentation is conducted on the rock image.ImagePy is used as the image preprocessing analysis method of opencast explosion bonded rock fragmentations,and the main points of image collection in open blasting pile and the way to consider the regional variation coefficient of small rock masses are defined.The bilateral filter plug-in based on ImagePy is developed. Three parameters(30,11,11)is selected for bilateral filtering analysis.The example analysis shows that this method can achieve favourablebinarization segmentation effect on the image processing of open-pit explosive rock blocks,and it also proves that the open-source image processing framework ImagePy has good feasibility in image pretreatment of blasting rock fragmentations.
