基于动态视觉测量的廊道沉降监测方法
Corridor settlement monitoring method based on dynamic visual measurement
摘要
Abstract
To achieve high-precision real-time monitoring of settlement in dam corridors and enhance safety assurance,a settlement monitoring method based on dynamic visual measurement is proposed and applied to the Xiabandi Reservoir in Xinjiang.This method innovatively integrates non-contact visual measurement technology with dynamic pose perception technology.Real-time images of corridor targets at monitoring points are captured by the camera's visual measurement unit,and the pixel coordinates of geometric centers are accurately identified and extracted using image processing algorithms.Meanwhile,the dynamic measurement unit synchronously collects real-time data on the camera's position and pose changes to calculate variations in the pitch angle.Furthermore,a settlement calculation formula is developed by integrating pixel displacement information with dynamic pose variation data.Based on this formula,pixel-level displacements of the monitoring points are precisely converted into engineering-scale settlement values.This approach effectively overcomes the limitations of traditional methods,such as total stations and static level instruments,in closed corridor environments,including low data acquisition frequency,poor timeliness,and inadequate adaptability to harsh conditions.The empirical application in the Xinjiang Xiabandi Water Conservancy Hub Project demonstrates millimeter-level monitoring accuracy,high real-time performance,and excellent adaptability to extreme climatic conditions,providing a reliable technical solution for safety monitoring of water conservancy projects in complex environments.关键词
