Problems solved by technology
[0003] Unmanned driving technology requires many sensors as a support to perceive the surrounding environment. The excellent performance of the perception system not only depends on the performance of each sensor, but also the sensor data time synchronization system. They are managed by their respective internal time systems, or by a combination of the sensor's internal time system, microprocessor, and computing unit. However, there are often deviations in timing between multiple time systems, resulting in out-of-synchronization of the data collected by the sensors, affecting Time Synchronization Accuracy

The invention discloses a time information using method and device, equipment and a storage medium. The method comprises the steps of sending a collection instruction to multiple acquisition devices; receiving multiple pieces of acquisition data sent by the multiple acquisition devices, wherein the multiple pieces of acquisition data are in one-to-one correspondence with the multiple acquisition devices; if global positioning system (GPS) time information corresponding to an acquisition instruction sending moment is acquired, and marking the GPS time information into each piece of acquisition data of the multiple pieces of acquisition data, wherein the GPS time information is sent by a global positioning system. According to the embodiment of the invention, the GPS time information can be used, and multiple time systems do not need to respectively control the multiple acquisition devices to send the acquisition instruction, so that the time synchronization precision can be improved.
Description
technical field [0001] The present application relates to the field of using time information, in particular to a method, device, equipment and storage medium for using time information. Background technique [0002] Unmanned driving has become an important aspect of technology development in the modern automotive industry and the electronic and electrical industry, so the technology for all aspects of unmanned driving has become a key research field of today's high-tech. [0003] Unmanned driving technology requires many sensors as a support to perceive the surrounding environment. The excellent performance of the perception system not only depends on the performance of each sensor, but also the sensor data time synchronization system. They are managed by their respective internal time systems, or by a combination of the sensor's internal time system, microprocessor, and computing unit. However, there are often deviations in timing between multiple time systems, resulting i...
