摘要: 传统的车辆目标检测算法需要为不同的图像场景选择合适的特征,导致泛化能力差。针对此问题,本文提出一种基于SSD(Single Shot MultiBox Detector)的图像车辆检测方法。该方法通过对多个尺度的卷积特征图进行预测来检测车辆,在一定程度上提升车辆的检测精度;找出原SSD方法在训练过程中的小缺陷,通过改进损失函数来优化训练速度。最后结合KITTI数据集进行训练。实验结果表明,该方法对车辆的检测具有较高的识别率,且比传统算法的效果更好。

Abstract: The traditional vehicle target detection algorithm needs to select appropriate features for different image scenes, resulting in poor generalization ability. Therefore, an image detection method based on SSD (Single Shot MultiBox Detector) for vehicle is proposed. The method detects the vehicle by predicting the convolutional feature maps of multiple scales, and improves the detection accuracy of the vehicle to a certain extent. The small defects of the original SSD method in the training process are found, and the loss function is improved to optimize the training speed. Finally, the KITTI data set is used for training. The experimental results show that the method has a higher recognition rate for vehicles and the effect is better than traditional algorithms.
