AI Technical Summary

Technical Problem

Existing technologies cannot achieve comprehensive, efficient, and accurate detection in narrow and complex pipeline environments. Traditional detection methods have blind spots and cannot cover all pipeline inner walls, which may lead to the omission of important defect information.

Method used

A binocular, all-angle laser 3D scanning device is used inside a narrow pipe. Combining a Mecanum wheel drive system and all-angle laser scanning technology, a ring laser pattern is scanned inside the pipe using a binocular camera and an all-angle laser emitter. The laser stripe segmentation method of GuideNet and the Steger algorithm are used to extract the center line of the laser stripe, and then 3D reconstruction and point cloud data are generated.

Benefits of technology

It enables omnidirectional scanning of the pipeline interior, avoiding blind spots, generating high-precision 3D point cloud data, adapting to narrow and complex pipeline structures, improving detection efficiency and accuracy, and is suitable for daily monitoring and maintenance of large-scale pipeline systems.

Abstract

本发明公开一种狭小管道内部双目全角度激光三维扫描装置及方法,装置包括麦克纳姆主驱动轮、双目相机、全角度激光发射器、从动轮。本发明利用装置进入管道匀速运动、并获取双目环形激光扫描双目图像序列进行矫正与校正处理后,通过基于GuideNet的激光条纹分割方法获取激光条纹分割结果,并基于Steger算法提取双目环形激光中心线,提取环形中段区域激光中心点并进行三维重建,利用该部分点云拟合暂态激光平面,并基于暂态激光平面拟合当前图像帧的全角度环形激光环三维点云,最后结合运动速度与图像帧率,实现每帧图像对应激光点云的拼接,实现管道内表面三维重建。本发明可为管道形变检测提供准确的数据,具有较高的工程应用价值。
