多尺度视觉测量融合的堆石料表观级配检测方法
A Method for Identifying Apparent Rockfill Gradation via Integrated Multi-scale Visual Measurement
摘要
Abstract
Due to the significant scale differences in rockfill gradation,common methods for image segmentation on particles often suffer from over-segmentation or under-segmentation,struggling to meet the requirements of engineering applications.Therefore,this paper proposes a contour extraction method integrating multi-scale visual measurement.Firstly,images of the paved rockfill are collected.Then,to address the problem of uneven segmentation scales caused by large particle size spans of rockfill,an integrated multi-scale visual measurement model is constructed in combination with Mask R-CNN,presenting an accurate approach to extract the contours of stones in different sizes.Based on the extracted results,a model is established to reconstruct the three-dimensional shape of particles and calculate the gradation,enabling fast evaluation of the apparent gradation of rockfill materials.Field experiments exhibit that this method provides high-precision identification of large-span particle sizes and can effectively support quick assessment of rockfill gradation on site.关键词
