Port Structure Inspection Based on 6-DOF Displacement Estimation Combined with Homography Formulation and Genetic Algorithm

A vision sensor-based 6-DOF displacement evaluation method incorporating a genetic algorithm was proposed to monitor the critical defects of port infrastructure, such as deflection, slope, and slip. The behavior structure, including subsidence, estimated based on specification target fixed structures nearby. calculates relative position structure measures movement over time. To improve measurement accuracy, used adjust intrinsic parameters that were previously using checkerboards. results measuring displacements tuned confirmed it has potential accurately measure facilities. possibility field application examined through an artificial induced in image facility create arbitrary between two points.
