Abstract

A system for measuring small displacement in remote a coplane is prepared as firm-joining cooperation mark with entity to be measured and connecting digital camera to image collection card being connected with computer for calculating out displacement data of cooperation mark then calculating out actual displacement amount of position to be measured.

Description

technical field [0001] The invention relates to a long-distance in-plane small displacement measurement system. Background technique [0002] Existing systems for measuring displacements such as building settlements can be classified into contact measurement systems and non-contact measurement systems. [0003] The practice of the contact measurement system is to paste the strain gauge at the position to be measured, directly measure the strain, and then convert it into displacement. In field operations, this method is cumbersome to implement, and to obtain high-precision results, the requirements for patch technology are very high. [0004] The non-contact measurement system is a method of light measurement. One of them is to use a total station. The total station can read the azimuth and distance of the target at the same time, so it can obtain the three-dimensional displacement of the target to be measured. However, in order to achieve high precision in long-distance ...
