摘要
本研究以墙壁拆除废料为例,研究了根据相机图像从无石棉混凝土中分辨出潜在含石棉成分的可行性。为此,对三种石棉替代材料和两种混凝土进行了粉碎和拍照。碎片图像的分类采用了 a) 形态和纹理特征,以及 b) 由预训练的 MobileNetV3 网络自动提取的特征。形态描述符包括碎块直径、圆度等。纹理则通过灰度级共现矩阵获得的灰度级强度来描述。根据自动提取的特征,支持向量机的分类准确率超过 99%。所提出的识别方法有望实现建筑和拆除废物中含石棉材料处理过程的自动化,而这一处理过程至今仍需要专家知识。
An Image-Based Approach to Automated Recognition of Asbestos-Containing Components in Wall Demolition Waste
The feasibility to discriminate potentially asbestos-containing components from asbestos-free concrete based on camera images using the example of wall demolition waste is investigated. For this, three types of asbestos substitute materials and two types of concrete are crushed and photographed. The classification of the fragment images is carried out with a) morphological and texture features and b) with features automatically extracted by the pretrained MobileNetV3 network. Feret diameters, circularity, and others served as morphological descriptors. The texture was described by measures of grey-level intensity, as obtained from the grey-level co-occurrence matrix. Support vector machines are found to achieve classification accuracies above 99 % based on the automatically extracted features. The presented identification approach is promising to automate the treatment process of asbestos-containing materials from construction and demolition waste, which is effortful and requires expert knowledge to this day.
