摘要

传统的检测相机通过捕捉光强图像来确定目标和检测缺陷,但在复杂的环境中,检测精度可能会降低。基于光偏振的信息可以表征材料的各种特征,如粗糙度、纹理和折射率,从而改进目标的分类和识别。本文采用基于噪声模板阈值匹配的方法对偏振图像进行去噪和预处理。本文还报告了基于 NSCT 变换的图像融合算法的设计情况,该算法用于融合光强图像和偏振图像。结果表明,相对于源图像,融合后的图像在主观和客观评价指标上都有所改善,能更好地保留边缘信息,有助于提高目标识别的准确性。该研究为多维光学信息在电力检测中的综合应用提供了参考。

Research on a multi-dimensional image information fusion algorithm based on NSCT transform.

Traditional inspection cameras determine targets and detect defects by capturing images of their light intensity, but in complex environments, the accuracy of inspection may decrease. Information based on polarization of light can characterize various features of a material, such as the roughness, texture, and refractive index, thus improving classification and recognition of targets. This paper uses a method based on noise template threshold matching to denoise and preprocess polarized images. It also reports on design of an image fusion algorithm, based on NSCT transform, to fuse light intensity images and polarized images. The results show that the fused image improves both subjective and objective evaluation indicators, relative to the source image, and can better preserve edge information and help to improve the accuracy of target recognition. This study provides a reference for the comprehensive application of multi-dimensional optical information in power inspection.
