Building digital image deformation monitoring system based on radar correction
The invention discloses a building digital image deformation monitoring system based on radar correction. The system comprises vision measurement equipment, radar measurement equipment, a stand column and data acquisition and algorithm equipment. Newly-built projects often cause deformation and even damage of existing buildings. And automatic monitoring is an effective way for guaranteeing the safety of the existing building. The measurement precision of the traditional automatic total station and the existing digital image deformation monitoring is greatly influenced by environments such as weather and even cannot be measured in rainy and foggy weather. And the microwave radar ranging has the important advantages of high monitoring precision and small environmental factor. However, radar ranging can only test and obtain the linear distance between a test point and a target point, and cannot obtain the two-dimensional or three-dimensional deformation of the target point. According to the method, the advantage of high environmental influence resistance of the microwave radar is utilized, errors caused by measurement of a digital image deformation monitoring technology under complex environmental conditions are calibrated, and automatic monitoring of object displacement in a multipoint, real-time, long-distance and low-cost mode is achieved, and environmental condition limitation is broken through.
本发明公开一种基于雷达修正的建构筑物数字图像变形监测系统。该系统包括视觉测量设备、雷达测量设备、立柱、数据采集与算法设备。新建工程往往导致临近既有建筑变形，甚至破坏。自动化监测对保障既有建筑安全的有效途径。传统的自动全站仪和现数字图像变形监测的测量精度受到天气等环境影响大，甚至雨雾天气无法测量。而微波雷达测距具有监测精度高、受环境因素小的重要优点。但雷达测距只能测试获得测试点与目标点的线性距离，无法获得目标点的二维或是三维变形。本发明利用微波雷达高抗环境影响的优点，校准数字图像变形监测技术在复杂环境条件下测量带来的误差，实现对物体位移多点、实时、长距离、低成本、打破环境条件限制的自动化监测。
