提出了一种基于深度学习的车辆分类模型来处理复杂的交通场景。该模型由车辆检测模型和分类模型两部分组成。在车辆检测模型中采用基于区域的卷积神经网络方法R-CNN(Regions with Convolutional Neural Network),从杂乱背景的图像中提取单个车辆图像,该步骤为下一个分类模型提供数据。在车辆分类模型中,将车辆图像导入CNN模型,并生成特征,然后使用联合贝叶斯网络来实现分类过程。实验表明,该方法可以有效识别交通图像中的车辆构造和模型。
A vehicle classification model based on deep learning is proposed to deal with complex traffic scenes. The model consists of two parts: vehicle detection model and classification model. A region-based convolutional neural network (R-CNN)method is used in the vehicle detection model to extract a single vehicle image from a disorderly background image. This step provides data for the next classification model. In the vehicle classification model, an image of a vehicle is included into a CNN model and a feature is produced, and then a joint Bayesian network is used to implement the classification process. Experiments show that the method can effectively identify vehicle structures and models in traffic images.
