夹层共底结构红外图像拼接方法

Infrared Image Stitching Method for Sandwich Bulkhead Structure

夹层共底贮箱体积庞大,采用脉冲红外无损检测技术单次只能检测一小片区域,需要数百次检测才能完成对夹层共底贮箱的检测,单个工程不利于缺陷位置的判断。本文采用固定重叠区域的红外图像拼接方法,重叠区域采用加权融合方式可有效消除拼缝,夹层共底结构侧边6个子区域采用弧形拼接方式,可有效解决弧形区域的拼接,可有效解决多工程拼接难题。采集工程缺陷标注后,拼接图像直接显示缺陷的位置信息,对于夹层共底结构缺陷信息判断带来了极大的便利。

A sandwich bulkhead structure has a large volume.Because infrared non-destructive testing technology can only detect a small area,hundreds of tests are required to detect the sandwich bottom structure,which is not conducive to determining the location of defects in a single project.This article proposes a fixed overlapping-area infrared image stitching method in which the overlapping area is fused using weighted fusion to effectively eliminate seams.The six sub-regions on the side of the sandwich bottom structure are stitched using an arc-shaped method.This approach not only solves the problem of stitching in multiple projects but also greatly improves the accuracy and efficiency of defect detection.After collecting and annotating the defects in the project,the stitched image directly displays the location information of the defects,which greatly facilitates the identification of defect information in the sandwich bulkhead structure.
