摘要

3D高斯泼溅通过高斯基替代了传统点云,利用其平滑特性,在保持数据精度的同时,有效地处理并可视化三维空间中的散点数据,实现更加连续和自然的图像渲染效果,在光学图像领域取得了重大成果,并成为了近期的研究热点.在SAR图像应用领域中,属性散射中心模型常被作为图像的基使用.本文尝试使用高斯基替代属性散射中心模型,通过实验对比了高斯基、属性散射中心模型,以及实际应用中常用的简化属性散射中心模型在SAR图像重建任务中的表现.结果表明,高斯基方法在能提供更优的图像重建质量前提下,在速度和稳定性上表现明显优于属性散射中心模型,该结果为SAR图像特征与目标信息提取提供了新思路.

Abstract

3D Gaussian splash substitutes traditional point clouds with Gaussian bases,utilizing their smooth character-istics.While maintaining data accuracy,it effectively processes and visualizes scattered data in three-dimensional space,achieving a more continuous and natural image rendering effects.This has made significant achievements in the field of optical imaging and has become a recent research hotspot.In the application domain of SAR imaging,the at-tribute scattering center model is often used as the basis for images.In this paper,an attempt is made to use Gaussian bases instead of attribute scattering center model.Through experimental comparisons,the performance of Gaussian ba-ses,the attribute scattering center model,and the commonly used simplified attribute scattering center model in SAR image reconstruction tasks are analyzed.The results show that the Gaussian basis method offers superior image recon-struction quality,with significantly better performance in terms of speed and stability compared to the attribute scatter-ing center model.These findings provide new insights for feature and target information extraction in SAR images.
