摘要
为了提高对目标检测的效果,提出基于残差密集块的激光遥感图像中目标检测方法.首先,设计基于残差密集块的卷积神经网络,在设计ReLU激活函数并完成网络训练后,基于含噪激光遥感图像的初步特征提取结果,利用单个卷积展开卷积映射处理,抽取出潜在干净图像.然后,通过聚类处理的方式,得到激光遥感图像中车辆目标的显著图,再利用大律法,通过建立的特征比例关系的方式检测出其中的目标信息.实验结果表明,应用该方法有效滤除激光遥感图像中的噪声,并精准检测出激光遥感图像中的车辆目标.相比于3种传统方法,该方法检测结果均值误差的最小值仅为0.015 6,说明该方法有效实现了设计预期.
Abstract
In order to improve the effectiveness of object detection,a method for object detection in laser remote sensing images based on residual dense blocks is proposed.Firstly,design a convolutional neural network based on re-sidual dense blocks.After designing the ReLU activation function and completing network training,based on the pre-liminary feature extraction results of noisy laser remote sensing images,use a single convolution to unfold the convolu-tional mapping process and extract potentially clean images.Then,through clustering processing,the saliency map of vehicle targets in the laser remote sensing image is obtained,and then the target information is detected using the es-tablished feature proportion relationship using the general law.The experimental results show that the application of this method effectively filters out noise in laser remote sensing images and accurately detects vehicle targets in laser re-mote sensing images.Compared to the three traditional methods,the minimum value of the mean error of the detection results of this method is only 0.015 6,indicating that this method effectively achieves the design expectations.
