The invention discloses a multi-source automatic driving test data acquisition and processing method and system, and the method comprises the steps: firstly, collecting various test data of automatic driving through a data collection device; and then, performing timestamp marking on all the obtained test data by adopting uniform synchronization time, and adding an accurate timestamp to each test data. Afterwards, different test data can be matched and aligned according to the timestamps so as to determine the test data participating in subsequent data fusion. And finally, selecting data which can be subjected to data fusion from various test data for fusion to form a multi-modal data set containing different data sources, and performing dimension reduction compression on the multi-modal data set, so that deep fusion of the multi-modal data is realized, and an automatic driving data set with higher quality is efficiently generated.

    本发明公开了一种多源自动驾驶测试数据采集、处理方法及系统,包括:首先,可以通过数据采集设备采集自动驾驶的各项测试数据。然后,可以采用统一的同步时间对获取到的所有测试数据进行时间戳标记,对每份测试数据中添加精确的时间戳。之后,可以根据时间戳对不同测试数据之间进行匹配对齐,以确定参与后续数据融合的测试数据。最后,从各项测试数据中选出能够进行数据融合数据进行融合,形成包含不同数据来源的多模态数据集,并对该多模态数据集进行降维压缩,从而实现多模态数据的深度融合,高效地生成质量更高的自动驾驶数据集。
