ROS-based intelligent driving data analysis and synchronization method

The invention discloses an intelligent driving data analysis and synchronization method based on ROS. Rosbag data is obtained from an intelligent driving controller and converted into a csv file; screening each csv file to obtain all corresponding data when the automatic driving mode is activated, and storing the data as an xls file; acquiring vehicle-mounted can data from a vehicle-mounted can network; performing time synchronization processing on the vehicle-mounted can data and the rosbag data forming the xls file; screening the data after time synchronization to obtain data required by testing to form a merged xls file; and selecting demand data from the merged xls file to make a comparison graph and display the comparison graph, thereby realizing synchronization and analysis of intelligent driving data. According to the data synchronization mode, an inherent synchronization mode based on a hardware protocol is broken, data synchronization can be completed by establishing a time relation through different
