Abstract

The embodiment of the invention discloses a data synchronization method, a processor and a vehicle-mounted terminal. The method comprises the following steps: when image acquisition equipment performsimage acquisition according to a set first acquisition rule, determining a timestamp of an image acquired by the image acquisition equipment; when the motion detection equipment performs motion dataacquisition according to a set second acquisition rule, determining a timestamp of the motion data acquired by the motion detection equipment; wherein the second acquisition rule and the first acquisition rule are rules enabling the data acquisition time of the image acquisition device and the data acquisition time of the motion detection device to have an association relationship. By applying thescheme provided by the embodiment of the invention, the accuracy of time synchronism of the image and the motion data can be improved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a data synchronization method, a processor, and a vehicle-mounted terminal. Background technique [0002] In the field of machine vision, visual-inertial odometer (Visual-Inertial Odometry, VIO) technology combines image and motion data to provide a reliable data source for machine control in order to achieve various functions. For example, in the field of autonomous driving technology, images and motion data synchronized with high precision in time are required to achieve more precise control of the vehicle. Time-synchronized images and motion data refer to images and motion data collected at the same time. [0003] In related technologies, in order to obtain time-synchronized images and motion data, the images and motion data are usually collected separately, and then images and motion data with the same acquisition time are screened out. The temporally synchronized...
