The invention provides a sample data generation method, sample data is used for performing model training or testing on a trajectory prediction model, and the method comprises the following steps: obtaining first data information, the first data information comprising vehicle state information and obstacle sensing information of a vehicle; determining second data information according to the first data information, wherein the second data information comprises first trajectory data of each obstacle corresponding to each vehicle; generating sample data according to the second data information, each set of sample data includes an input portion of model training or testing determined based on a set of first trajectory data of a corresponding obstacle in the second data information and an output portion of model training or testing determined based on a corresponding set of first trajectory data in the second data information. According to the method, the sample data in the format required by the model can be automatically generated, the sample data generation efficiency is improved, the data is directly converted into the format required by the model, the time consumption of model training is reduced, and the model training efficiency is improved.

    本发明提供一种样本数据生成方法,样本数据用于对轨迹预测模型进行模型训练或测试,其包括:获取第一数据信息,第一数据信息包括车辆的自车状态信息和障碍物感知信息;根据第一数据信息确定出第二数据信息,第二数据信息包括与各自车相对应的各个障碍物的第一轨迹数据;根据第二数据信息生成样本数据,每组样本数据均包括基于第二数据信息中的相应障碍物的一组第一轨迹数据确定出的模型训练或测试的输入部分和基于第二数据信息中的相应组的第一轨迹数据确定出的模型训练或测试的输出部分。本发明能够实现自动化地生成模型所需格式的样本数据,提高样本数据生成效率,且将数据直接转换成模型所需格式,减少了模型训练耗时,提升了模型训练效率。
