PIV analysis system for large-scale landslide-generated impulse waves based on multi-lens array camera
为解决滑坡涌浪三维缩尺试验中大视野与高分辨率流场测量难以兼顾的问题,建立了基于多目阵列相机的大型滑坡涌浪PIV分析系统,采用了广角畸变校正、不规则图像四角点映射、图像快速融合拼接以及大型滑坡涌浪流场PIV分析等4项关键技术,实现了对三维缩尺试验下滑坡涌浪运动过程的观测与PIV分析.以大型三维王家山滑坡涌浪物理模型试验为例进行了滑坡涌浪PIV分析,验证了大型滑坡涌浪PIV分析系统的精确度与可行性,可为进一步研究三维缩尺试验下滑坡涌浪的运动过程提供借鉴.
To address the challenge of balancing a large field of view and high-resolution flow field measurement in 3D scaled model tests of landslide-generated impulse waves,we developed a PIV analysis system for large-scale landslide-generated impulse waves based on a multi-lens array camera.This system integrates four key technologies:wide-angle distortion correction,irregular image corner point mapping,rapid image fusion and stitching,and PIV analysis for large-scale landslide-generated impulse wave flow fields.It enables observation and PIV analysis of the movement process of landslide-generated impulse waves in 3D scaled model tests.Taking the large-scale 3D physical model test of Wangjiashan landslide-generated impulse waves as an example,PIV analysis of the landslide-generated impulse wave flow field was conducted.The results verify the accuracy and feasibility of the PIV analysis system for large-scale landslide-generated impulse waves,providing a reference for further research on the movement process of landslide-generated impulse waves in 3D scaled model tests.
