Displacement Field Calculation of Large-Scale Structures Using Computer Vision with Physical Constraints: An Experimental Study

نویسندگان

چکیده

In recent years, computer vision-based structural displacement acquisition technique has received wide attention and research due to the advantages of easy deployment, low-cost, non-contact. However, field large-scale structures is a challenging topic as result contradiction camera field-of-view resolution. This paper presents calculation framework with integrated vision physical constraints using only one camera. First, full-field image structure obtained by processing multi-view stitching technique; second, meshed node displacements are calculated an improved template matching method; finally, non-node described shape functions considering constraints. The developed was validated scaled bridge model evaluated proposed evaluation index for accuracy. can provide effective way obtain fields efficiently cost-effectively.

VOLUME MINIMIZATION WITH DISPLACEMENT CONSTRAINTS IN TOPOLOGY OPTIMIZATION OF CONTINUUM STRUCTURES

In this paper, a displacement-constrained volume-minimizing topology optimization model is present for two-dimensional continuum problems. The new model is a generalization of the displacement-constrained volume-minimizing model developed by Yi and Sui [1] in which the displacement is constrained in the loading point. In the original model the displacement constraint was formulated as an equali...

Analysis of Large-scale Displacement Using Radar Interferometry Technology in Open-pit Mines (Case Study: Gol Gohar Sirjan Mine)

  Abstract Mines with their displacements cause damage to infrastructure and land, so it is important to control the displacement caused by mines. Also, the amount of minerals extracted from mines has always been of interest to managers. On the other hand, radar interferometry, given the production of repetitive and full images and the acceptable accuracy of this method, in examining be sugge...

OPTIMIZATION OF LARGE-SCALE TRUSS STRUCTURES USING MODIFIED CHARGED SYSTEM SEARCH

Optimal design of large-scale structures is a rather difficult task and the computational efficiency of the currently available methods needs to be improved. In view of this, the paper presents a modified Charged System Search (CSS) algorithm. The new methodology is based on the combination of CSS and Particle Swarm Optimizer. In addition, in order to improve optimization search, the sequence o...
