基于大核选择和形状自适应的遥感图像目标检测OA

Target Detection in Remote Sensing Images Based on Large Kernel Selection and Shape Adaptation

中文摘要英文摘要

光学遥感图像目标检测是遥感图像数据智能解译的关键技术.为了解决遥感图像目标检测时,目标尺度差异大,目标受背景因素干扰,目标形状各异的问题,提出了LMK(large multiscale kernel)网络.该网络通过大核卷积分解和多尺度注意力机制模块,能够动态调整空间感受野,从而更好地捕获遥感场景中物体的上下文信息.此外,设计了一种面向目标检测的形状自适应选择(SAS,shape-adaptive selection)标签分配策略.该策略将目标形状信息集中于长宽比,通过结合物体的形状信息和特征分布计算IoU(intersection over union)最优阈值.针对遥感图像目标姿态旋转定位难的问题,引入了KFIoU损失函数.实验结果表明,所提出的目标检测模型在HRSC2016、UCAS-AOD和DOTA数据集上的精度分别达到了96.73%、97.85%和77.26%.改进后的模型优于目前绝大多数目标检测算法.

Target detection in optical remote sensing images is a key technology for the intelligent interpretation of remote sensing data.To address the challenges posed by of significant scale variations,background interfer-ence and the diversity of target shapes in remote sensing image detection,this paper proposes the Large Multi-scale Kernel(LMK)network.This network utilized large kernel convolution and a multi-scale attention mecha-nism to dynamically adjust the spatial receptive field,thereby enhancing the capture of contextual information about objects in remote sensing scenes.Furthermore,a Shape-Adaptive Selection(SAS)label allocation strat-egy was designed for target detection,which focused on the aspect ratio of the target shapes and calculated an optimal IoU threshold based on the shape information and feature distribution.To address the difficulty of target orientation and positioning in remote sensing images,this paper introduced the KFIoU loss function.Experi-mental results show that the proposed target detection model achieves accuracies of 96.73%,97.85%,and 77.26%on the HRSC 2016,UCAS-AOD,and DOTA datasets,respectively,outperforming most existing target detection algorithms.
