Abstract

The invention provides a multi-sensor synchronization method. The multi-sensor synchronization method comprises the following steps: acquiring a first view field direction of a first sensor; acquiring a second view field direction of a second sensor; obtaining the time of the current moment; judging whether the second view field direction is the same as the first view field direction or not; when the second field-of-view direction is different from the first field-of-view direction, calculating the synchronization time when the second field-of-view direction is the same as the first field-of-view direction; judging whether the current time is a preset time earlier than the synchronization time or not; triggering the first sensor to output a first image when the time of the current moment is a preset time earlier than the synchronization time; acquiring a first image and adjusting a first sensing parameter of the first sensor according to the first image to obtain a second sensing parameter; and when the second view field direction is the same as the first view field direction, triggering the first sensor to output a second image based on the second sensing parameter. According to the technical scheme, the synchronization problem among various sensors is effectively solved.

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...
