    摘要:

    高速公路客货混行是交通事故的重要诱因,据统计造成10人以上死亡的交通事故中,货车与大客车相撞占据了75%。虽然国内外都已经开始推广客货分道,但是对客货分道行驶的监管还不完善,目前的监督手段还主要是摄像头拍照,后期由工作人员对违规行为进行检查,暂时还缺少一个成熟的关于客货分道的智能检测方案。本文采用视频图像检测法对高速公路进行研究和应用,本文构建了基于机器学习和计算机视觉的视频图像检测模式,以提高视频检测的稳定性和准确率,提出了基于尺度不变特征变换(Scale invariant feature transformation,SIFT)池化的车辆特征提取模型,摒除传统视频背景建模稳定性和准确率不高的缺陷,获取车辆车型特征数据和分道行驶参数,经过试点样本训练后,实验结果表明车型识别的准确率高达95%以上,车辆分道检测的准确率也能达到90%左右。

    Abstract:

    Highway passenger and cargo mixed operation is an important incentive for traffic accidents. According to statistics, more than 10 people died in traffic accidents, and the collision between trucks and buses accounted for 75%. Although both home and abroad have begun to promote the passenger and freight division, but the supervision of the passenger and freight traffic is not perfect, the current supervision means is also mainly camera photography, later by the staff on the violation of the inspection, and the lack of a mature intelligent detection scheme about the passenger and cargo separation. A video image detection method is used to study and apply to the expressway. In order to improve the accuracy and stability of video detection, a video image detection model based on computer vision and depth learning is built in this paper. The Scale invariant feature transformation (SIFT) pool based on the scale invariant feature transform is proposed. The model of vehicle feature extraction was used to remove the shortcomings of traditional video background modeling with low stability and accuracy, and the feature data and running parameters of vehicles were obtained. After the pilot sample training, the experimental results show that the accuracy of vehicle recognition is as high as 95%, and the accuracy of vehicle lane detection can also reach about 90%.
