Abstract

The present invention provides a multi-sensor synchronization method, comprising: obtaining the first field of view direction of the first sensor; obtaining the second field of view direction of the second sensor; obtaining the time at the current moment; judging the difference between the second field of view direction and the first Whether the direction of the field of view is the same; when the direction of the second field of view is different from the direction of the first field of view, calculate the synchronization time when the direction of the second field of view is the same as the direction of the first field of view; judge whether the time at the current moment is ahead of the synchronization time Set the time; when the current time is ahead of the synchronization time by the preset time, trigger the first sensor to output the first image; acquire the first image and adjust the first sensing parameter of the first sensor according to the first image to obtain the second sensor and when the direction of the second field of view is the same as the direction of the first field of view, triggering the first sensor to output a second image based on the second sensing parameter. The technical scheme of the invention effectively solves the synchronization problem among various sensors.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a multi-sensor synchronization method and system, and a main control device. Background technique [0002] The detection of obstacles in the driving process of unmanned vehicles is one of the key technologies of the environmental perception system. In the prior art, sensors are usually installed on the driverless car. During the driving process of the driverless car, the sensor is used to collect the environmental data around the driverless car in real time and transmit it to the control system of the driverless car. Data analysis realizes the control of driverless cars. [0003] Cameras and lidar are two of the most commonly used sensors today. However, it is not enough to control driverless cars only through environmental data collected by cameras or lidar. When an unmanned vehicle is driving in an unknown and complex environment, it is necessary to use a va...
