AI Technical Summary

Problems solved by technology

For example, mmWave radar can work around the clock and has high range and speed measurement accuracy, but its classification effect is poor
The camera has a strong resolution and has a strong target classification effect, but because of the loss of depth information, the camera's ranging and speed measurement capabilities are poor
In addition, lidar has better depth information, and can also perform ranging and speed measurement, but its detection distance is relatively short

Abstract

The embodiment of the present application discloses a communication method and device, wherein the method is applied to a smart device, and the smart device includes multiple sensors. The method includes: determining N target sensors from a plurality of sensors, where N is an integer greater than 1. The second time of each of the N target sensors is corrected to the first time of the first clock. By adopting the embodiment of the present application, the time of different sensors in the smart device can be synchronized, so as to ensure accurate fusion of data collected by different sensors.

Description

technical field [0001] The embodiments of the present application relate to the technical field of time synchronization, and in particular, to a communication method and device. Background technique [0002] In automatic driving and assisted driving, intelligent vehicles often need to perceive the surrounding environment through various sensors. Among them, the more typical sensors include millimeter wave radar, camera and lidar. Intelligent vehicles can detect and classify the surrounding environment of the vehicle through these sensors, and transmit the acquired information to the planning and control module to form a decision on the future driving path of the vehicle, and finally execute it through the actuator to complete the entire auxiliary system. The process of driving or autonomous driving. [0003] Different types of sensors often have different characteristics and advantages and disadvantages. For example, millimeter-wave radar can work around the clock and has...
