Problems solved by technology
However, due to the limitation of sensor parameters or information types, it is difficult to achieve true time synchronization between different types of information obtained based on multi-sensing technology.
Especially in the field of autonomous driving, it is difficult to achieve time synchronization between the point cloud data collected based on lidar and the image data collected based on the camera. The asynchronous information has caused serious problems for subsequent data collection, data labeling and information fusion between multiple sensors. adverse effects

The invention discloses an information synchronization method, an information synchronization device and electronic equipment. The information synchronization method comprises the steps of obtaining at least one image frame in a first space range, and determining a first timestamp information set corresponding to the at least one image frame; acquiring point cloud data in a second spatial range and scanning information corresponding to the point cloud data, determining the point cloud data as a plurality of point cloud units based on the scanning information, and determining a second timestampinformation set corresponding to the plurality of point cloud units, the first spatial range and the second spatial range having overlapped regions; and synchronizing the point cloud data and the atleast one image frame based on the first timestamp information set and the second timestamp information set. Compared with an existing information synchronization method, the information synchronization method has the advantages that the synchronization accuracy of the information can be effectively improved, synchronization errors are reduced, and then synchronization information with finer granularity is provided for subsequent information fusion and other operations.
Description
technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an information synchronization method, an information synchronization device, and electronic equipment. Background technique [0002] With the rapid development of sensing technology, multi-sensing technology that can acquire different types of information has attracted more and more attention. However, due to the limitations of sensor parameters or information types, it is difficult to achieve real time synchronization between different types of information obtained based on multi-sensing technology. Especially in the field of autonomous driving, it is difficult to achieve time synchronization between the point cloud data collected based on lidar and the image data collected based on the camera. The asynchronous information has caused serious problems for subsequent data collection, data labeling and information fusion between multiple sensors. adverse eff...
