The invention discloses a vehicle track complementing and matching method based on a road network. The method comprises the following steps: carrying out denoising and deduplication preprocessing on vehicle track data; a Lagrange interpolation method and a cube spline method are combined to supplement missing trajectory data; 70% of missing points in the trajectory data are supplemented by using a Lagrange interpolation method, and points on a function are selected to be supplemented into the trajectory data; 30% of track missing points on the two sides are supplemented by adopting a cubic spline method; and obtaining road network data, and using the Euclidean algorithm to take the road with the minimum distance as a real track path. According to the vehicle trajectory complementing and matching method based on the road network, a real running path is matched by complementing a running trajectory and comparing real road data of the road network. The real road data of the road network are effectively combined while model training is avoided, and the validity and authenticity of missing point completion are considered.
本发明公开了一种基于路网的车辆轨迹补全和匹配的方法,包括将车辆轨迹数据进行去噪和去重复预处理;结合拉格朗日插值法和cubic spline方法补充缺失轨迹数据;使用拉格朗日插值法补充轨迹数据中间70%的缺失点,选择函数上的点补充到轨迹数据中;采用cubic spline方法补充两侧30%的轨迹缺失点;获取到路网数据,使用欧几里得算法,取距离最小的一条道路为真实轨迹路径。本发明基于路网的车辆轨迹补全和匹配方法,通过对运行轨迹的补全和路网真实道路数据对比,匹配到真实运行的路径。在避免负责模型训练的同时,有效的结合了路网真实道路数据,兼顾了缺失点补全的有效性和真实性。
