The invention relates to a vehicle trajectory optimization method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring an original track point of a vehicle, and dividing an original driving track of the vehicle into a linear track section and a curved track section based on the original track point; a second-order Bezier curve is adopted to fit the original track points corresponding to the curve track segments, and curve track line segments are obtained; and respectively calculating the driving speed of the vehicle at each original track point in the linear track segment, and inserting a corresponding number of virtual track points between adjacent original track points of the linear track segment based on the driving speed to form a linear track segment. According to the embodiment of the invention, the driving path of the vehicle is displayed by adopting the driving track in the digital twin system, so that the phenomena of jerking and sudden speed increase and decrease at the turning position of the vehicle can be prevented, the continuity of displaying the driving path of the vehicle is ensured, and the viewing experience of a user is improved.
本申请涉及一种车辆轨迹优化方法、装置、电子设备及计算机可读存储介质。该方法包括:获取车辆的原始轨迹点,基于所述原始轨迹点将所述车辆的原始行驶轨迹分为直线轨迹段和曲线轨迹段;采用二阶贝塞尔曲线对所述曲线轨迹段对应的原始轨迹点进行拟合,得到曲线轨迹线段;分别计算所述车辆在直线轨迹段中各原始轨迹点的行驶速度,基于所述行驶速度,在所述直线轨迹段的各相邻原始轨迹点之间插入对应数量的虚拟轨迹点,形成直线轨迹线段。本申请实施例在数字孪生系统中采用该行驶轨迹显示车辆的行驶路径,能够防止车辆在转弯处出现顿挫和速度突然增加、降低的现象,保证车辆行驶路径显示的连续性,提升用户观看体验。
