Abstract

In this paper, the detection of fiber distribution in six UHPC slabs with fiber content of 1%, 2%, 3%, and horizontal pouring and vertical pouring is studied by image recognition method. The results show that: firstly, the fiber distribution can be identified by a series of processing steps, such as grayscale and binarization of fiber source image, extraction of initial detection area, extraction of fiber contour and segmentation of fiber adhesion area. Furthermore, it is proposed that the scaling curve of n-e detection area per pixel of fiber number can anchor the effective recognition area range of fiber. Secondly, the statistical analysis of the identification results can visually draw the fiber distribution maps of different types of UHPC slabs in different directions, and quantitatively characterize the fiber distribution uniformity of UHPC slabs by quoting the evaluation index of fiber distribution coefficient. Finally, the cross-sectional fiber Scatter Density Plot can perceptually show the degree of fiber dispersion and its position distribution. The more uniform the color, the more uniform the fiber distribution in the cross-section of the specimen.
基于图像识别方法的超高性能混凝土板纤维空间数量分布研究
本文采用图像识别方法研究了纤维含量分别为 1%、2%、3% 以及水平浇筑和垂直浇筑的六种超高性能混凝土板中纤维分布的检测。结果表明:首先,通过对纤维源图像进行灰度化和二值化、提取初始检测区域、提取纤维轮廓和分割纤维粘附区域等一系列处理步骤,可以识别纤维分布。此外,还提出了纤维编号每像素 n-e 检测区域的缩放曲线,可以锚定纤维的有效识别区域范围。其次,通过对识别结果的统计分析,可以直观地绘制出不同类型超高性能混凝土板材在不同方向上的纤维分布图,并通过引用纤维分布系数这一评价指标来定量表征超高性能混凝土板材的纤维分布均匀性。最后,截面纤维散布密度图可以直观地显示纤维的散布程度及其位置分布。颜色越均匀,说明试样横截面上的纤维分布越均匀。

期刊介绍: Advances in Structural Engineering was established in 1997 and has become one of the major peer-reviewed journals in the field of structural engineering. To better fulfil the mission of the journal, we have recently decided to launch two new features for the journal: (a) invited review papers providing an in-depth exposition of a topic of significant current interest; (b) short papers reporting truly new technologies in structural engineering.
