Performance Evaluation of Feature Matching Techniques for Detecting Reinforced Soil Retaining Wall Displacement

چکیده
Image registration technology is widely applied in various matching methods. In this study, we aim to evaluate the feature performance and find an optimal technique for detecting three types of behaviors—facing displacement, settlement, combined displacement—in reinforced soil retaining walls (RSWs). For a single block with artificial target multiblock structure natural targets, five popular detectors descriptors—KAZE, SURF, MinEigen, ORB, BRISK—were used resolution performance. comparison, repeatability, score, inlier features were analyzed based on number extracted matched features. The axial error (ARE) was verify accuracy methods by comparing position between estimated real results showed that KAZE method best detector descriptor RSWs (block shape target), highest probability successfully experiment, as similar attached. Therefore, behaviors RSW blocks can be using without installing target.

Simplified Procedure to Evaluate Earthquake-induced Residual Displacement of Geosynthetic Reinforced Soil Retaining Walls
Based on a series of shaking table model tests, it was found that the eŠects of 1) subsoil and backˆll deformation, 2) failure plane formation in backˆll, and 3) pullout resistance mobilized by the reinforcements on the seismic behaviors of the geosynthetic reinforced soil retaining walls (GRS walls) were signiˆcant. These eŠects cannot be taken into account in the conventional pseudo-static ba...
متن کاملDetecting and matching feature points
This paper proposes a new feature point detector which uses a wedge model to characterize corners by their orientation and angular width. This detector is compared to two popular feature point detectors: the Harris and SUSAN detectors, on the basis of some defined quality attributes. It is also shown how feature points between widely separated views can be matched by using the information provi...
متن کاملOptimization of retaining wall design using recent swarm intelligence techniques
In this paper, cantilever retaining wall design is studied as an important optimization task in civil engineering. The current study explores the efficiency of some recent swarm intelligence techniques: accelerated particle swarm optimization (APSO), firefly algorithm (FA), and cuckoo search (CS). These algorithms are verified using two benchmark case studies. In order to better determine the p...
متن کاملSeismic stability of reinforced-soil wall by pseudo-dynamic method
Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil wall. A pseudo-dynamic method is adopted in the present analysis, which considers the effect of phase difference in both the shear and primary...
متن کاملEvaluation of Similarity Measures for Template Matching
Image matching is a critical process in various photogrammetry, computer vision and remote sensing applications such as image registration, 3D model reconstruction, change detection, image fusion, pattern recognition, autonomous navigation, and digital elevation model (DEM) generation and orientation. The primary goal of the image matching process is to establish the correspondence between two ...
