摘要
随着深度学习的研究热潮,近年来对车辆目标的检测逐步从机器学习方法转变为深度学习方法.目前,大多数深度学习方法对车辆目标的检测都存在不同程度的错检漏检问题.针对车辆目标检测中存在的小目标的错检漏检、截断式待检目标的漏检和重叠遮挡待检目标的漏检等问题,提出一种基于增量学习数据集的车辆目标检测方法,该方法与Faster R-CNN算法结合对车辆目标实现检测和分类.在实验的最后,分别从主观判断和客观检测数据两个方面,对比了车辆目标检测中未使用增量学习方法和使用增量学习方法对实验结果的影响.实验证明,使用基于增量学习和Faster R-CNN的车辆目标检测方法在主观判断方面对错检漏检的目标有明显地改善效果,从客观数据分析,使用该方法与未使用增量学习方法相比,VGG16网络mAP值提升了4%,ResNet101网络mAP值提升了6%.
With the research boom of deep learning,vehicle target detection has gradually changed from machine learning to deep learning in recent years.At present,most of the deep learning methods have different degrees of error detection and omission in vehicle target detection.The vehicle detection method based on incremental learning dataset is proposed to solve the problems of small targets error detection and the omission of truncated and overlapping targets.This method is combined with faster R-CNN algorithm to detect and classify vehicle targets.At the end of the experiment,the influence of with/without incremental learning method on the experimental results was compared from two aspects of subjective judgment and objective test data.The result show that the vehicle detection method based on incremental learning and faster R-CNN has significantly improved the performance in subjective judgment of the missed targets.Objective data also show that the VGG16 network mAP value is increased by 4%and the ResNet101 network mAP value is increased by 6%compared with the incremental learning method.
