| 摘 要： | 针对YOLOv3算法对小目标检测较差及出现较多漏检的问题,本文提出了一种优化的YOLOv3算法.首先使用K-means算法计算出与数据集相适用的锚框;其次将扩张卷积引入到YOLOv3网络,用来增强网络高层的感受野,改善小目标的检测效果;然后使用深度可分离卷积取代YOLOv3网络残差模块中的普通卷积,可减少计算量,从而得到一种新型卷积神经网络结构;最后在数据集上进行对比试验.结果表明,优化的YOLOv3算法能够检测出更多目标,降低漏检率,相比于YOLOv3算法,其召回率提高11.86%,F1-score提高2.99%.

| Abstract: | Aiming at the problem that YOLOv3 (You look only once) algorithm has poor detection of small targets and many missed detection, this paper proposes an optimized YOLOv3 algorithm. Firstly, K-means algorithm is used to calculate the anchor frame suitable for the data set in this paper. Then, extended convolution is introduced into YOLOv3 network to enhance the high-level perception field of the network, improve the detection effect of small targets, and secondly, depthwise separable convolution is used. It replaces the ordinary convolution in YOLOv3 network residual module, reduces the calculation parameters, and thus obtains a new convolution neural network structure. Then the comparative experiments are carried out on the data set in this paper. The experimental results show that the optimized YOLOv3 algorithm can detect more targets and reduce the missed detection rate. Compared with YOLOv3 algorithm, its recall rate is increased by 11.86% and F1-score by 2.99%. |
