The invention relates to the technical field of intelligent traffic, in particular to a ramp road section passing energy efficiency detection method and system. The method comprises the following steps: acquiring image data of a ramp road section, and constructing a virtual road model of the ramp road section; acquiring image data and vehicle position detection data of passing vehicles on ramp road sections, inputting the image data and the vehicle position detection data into the pre-training model, and matching three-dimensional models corresponding to the passing vehicles; and mapping the matched three-dimensional model into the virtual road model of the ramp road section according to vehicle position detection data to display the vehicle passing condition in a three-dimensional visualization manner. According to the invention, the virtual three-dimensional model of the vehicle is mapped to the created virtual road model, three-dimensional visualization real-time display is carried out on the passing vehicle, and the lane changing and line pressing condition of the passing vehicle is judged according to the intersection of the moving track of the passing vehicle and the traffic marking characteristics in the virtual road model and early warning is carried out. Therefore, the three-dimensional visual management and control of the ramp road section can be realized, and the traffic condition of the ramp road section can be mastered in real time instead of traditional snapshot.

    本发明涉及智能交通技术领域,具体涉及一种匝道路段通行能效检测方法和系统。该方法包括:获取匝道路段图像数据,并构建匝道路段虚拟道路模型;采集匝道路段通行车辆的图像数据及车辆位置探测数据,输入预训练模型,匹配通行车辆对应的三维模型;根据车辆位置探测数据将匹配的三维模型映射到匝道路段虚拟道路模型中三维可视化展示车辆通行状况。本发明将车辆虚拟的三维模型映射到创建的虚拟道路模型中,对通行车辆进行三维可视化实时展示,根据通行车辆的移动轨迹与虚拟道路模型中的交通标线特征的交叉判断通行车辆的变道压线情况并预警,以便实现对匝道路段的三维可视化管控,替代传统的抓拍实时掌握匝道路段通行状况。
