Sedimentation detection system

Abstract

The invention provides a sedimentation detection system which comprises a standard liquid storage container, a detection liquid storage container, a communicating pipe, a liquid to be detected and a shooting device, wherein the communicating pipe is used for communicating the standard liquid storage container with the detection liquid storage container; the liquid to be detected is in the standardliquid storage container, the detection liquid storage container and the communicating pipe; at least one part of the detection liquid storage container is bent and transparent, and scales are markedon the at least one part; and the positions of the scales represent the heights in the vertical direction; and the shooting device is positioned outside the detection liquid storage container, and isused for shooting the relative positions between the crossed part between the liquid level of the liquid to be detected and the at least one part and the scales, so as to obtain the liquid level height of the liquid to be detected. The object distances between scale identifications, at different positions, of the scales and a center camera are improved, the definition of the scale identificationsat the edge positions of images is improved, and market requirements on high precision, high reliability, high stability and high disturbance rejection in the real-time on-line monitoring field of civil engineering can be met.

Description

technical field [0001] The invention belongs to the technical field of civil engineering measurement, and relates to a detection system, in particular to a settlement detection system. Background technique [0002] Due to the influence of natural disasters, geological changes, building aging, engineering construction in surrounding areas and other factors, there are settlements and deformations of buildings that have been built or are under construction. In order to ensure the safety of people and property, settlement of buildings is required in many occasions. Real-time online monitoring. [0003] Due to the following characteristics of settlement monitoring in the field of civil engineering: 1. The change value to be measured is small; 2. The change to be measured is slow; 3. The distance span between the points to be measured is large; 4. The measurement period to be measured is long, which generally lasts for several years Decades or even hundreds of years; 5. The worki...

Problems solved by technology

The problem is that in order to improve the recognition accuracy of the liquid level position, the resolution of the picture must be used to the maximum, that is, the more pixels contained between the unit scales of the ruler on the picture, the better. Therefore, the range of the settlement device is There is a mutual matching relationship with the camera's viewing angle boundary

It can be seen that when the liquid level is at the edge of the ruler in the picture, the recognition accuracy of the unit scale will be greatly reduced compared with the center of the ruler

At the same time, since the object distance at the center of the ruler is smaller than that at the edge of the ruler, when the image at the center of the ruler is clear, the image at the edge of the ruler will be relatively blurred
