摘要/Abstract

摘要： 针对河港工模型试验中的泥沙测量与研究,借助B超仪和三维定位行走控制平台构建了一个含沙量及其垂线分布的分析与测量系统。系统利用B超成像技术获取含沙水流中悬浮沙粒的图像,针对B超图像编写含沙量分析软件,分析图像中指定区域的沙粒成像光斑面积的灰度浓度。通过率定试验,建立灰度浓度与水中实际含沙量的对应关系,并利用这种对应关系来计算待测含沙量。系统实现了较低含沙量及其垂线分布的在线同步分析与测量,具有操作简单、直观可视、实时性好、灵敏度高的特点。

关键词: 含沙量分析软件, B超图像, 灰度浓度, 率定试验, 垂线分布

Abstract: A system for the measurement and analysis of sediment concentration and its vertical distribution is built for river and port engineering model test with the help of B-mode ultrasound diagnostic apparatus and 3-D position control platform. B-mode ultrasound imaging technique is employed to obtain the images of suspended sediment in silt-carrying flow, and analysis software is written for B-mode ultrasound images to analyze the grayscale concentration of the imaging area. Through calibration test, the relationship between grayscale concentration and actual sediment concentration is established and is used to measure unknown concentration in the model. This system accomplishes the synchronous analysis and measurement of sediment concentration and its vertical distribution online with simple operation, direct observation, good real-time performance and high sensitivity.

Key words: sediment concentration analysis software, B-mode ultrasound image, grayscale concentration, calibration test, vertical distribution
