摘要: 针对井筒图像对比度小、干扰噪声多、分割精度不高、识别效率低等问题,提出了一种基于图像增强与正则约束的改进活动轮廓模型。图像增强算子能够改善井筒图像的对比度,扩大灰度动态范围,抑制噪声干扰。正则约束因子,包括长度约束因子、面积约束因子和距离函数约束因子,能够减少初始轮廓对曲线演化的影响,实现轮廓曲线平滑快速向目标边界移动,并最终与目标边缘吻合。实验结果表明,本文模型在算法性能和分割效果上都优于C-V模型和LBF模型,能够快速准确识别井筒病害,提高井筒巡检的自动化程度。

Abstract: In the images of mine shaft, there are many problems such as the low image contrast, the more image noises and the low efficiency of image segmentation accuracy. In order to solve these problems, we propose an improved active contour model based on image enhancement and regularization constraint. The image enhancement can improve the image contrast, expand the dynamic range of gray value, and reduce the noise effect. The regular constraints include the length constraint, the area constraint and the distance function constraint. They can reduce the influence of initial contour on the evolution of the curve, realize the contour curve to move quickly to the target boundary, and end up with the edge of the target. Experimental results show that the proposed model is superior to the C-V model and LBF model in the performance and segmentation results. This model can recognize the mine shaft diseases quickly and accurately, which can improve the degree of automation of mine shaft inspection.
