图像处理技术在推移质运动颗粒参数提取中的应用
Application of Image Processing Technology to Extracting Parameters of Bedload Motion Particles
摘要
Abstract
The motion regularity of non-uniform bedload particles has been a difficulty in sediment research, and ex-tracting the parameters of non-uniform bedload particles is a basic work to overcome the difficulty. Through flume experiment of non-uniform bedload on rough bed, a large amount of videos of particle motion were obtained, and some of the videos were selected for processing and research:firstly the video shot was converted into images by im-age conversion software, and then the deformity was corrected and the background noise was removed of the conver-ted images by spatial transformation and cutting;lastly the sediment particle contours were extracted by selecting a reasonable threshold. Furthermore, parameters inclusive of particle size and particle volume were calculated to pro-vide basis for obtaining the basic information of bed load particles motion. The research offers scientific and im-proved, reliable data for researching the transport mechanism of non-uniform bed load sediment.关键词
