Abstract

The present application discloses a data acquisition method and device for an unmanned vehicle. The unmanned vehicle is provided with a lidar sensor and a camera sensor, and a specific embodiment of the method includes: acquiring the acquisition period of the lidar sensor as the first period; acquiring the start time of the current time window; performing the following Data processing step: perform real-time acquisition and storage operations on the data packets collected by the lidar sensor and the camera sensor after the start time of the current time window; determine whether the following conditions are met: from the current time window The first period has passed from the starting time to the current time; in response to determining that the condition is satisfied, setting the starting time of the current time window as the current time, and continuing to execute the data processing step. This embodiment realizes the aligned storage of the data packets collected by the laser radar sensor of the unmanned vehicle and the data packets collected by the camera sensor.

Description

technical field [0001] The present application relates to the technical field of motor vehicles, specifically to the technical field of unmanned vehicles, and in particular to a data acquisition method and device for unmanned vehicles. Background technique [0002] The control system of an unmanned vehicle relies on sensors to perceive the surrounding environment, including vehicles, pedestrians, and traffic signs. Unmanned vehicles are usually equipped with a variety of sensor devices to obtain more information. Different sensors can complement each other to provide richer information for the control system of unmanned vehicles to perceive. Lidar sensors and camera sensors are the most commonly used and also the most important sensor devices in unmanned vehicles. [0003] The lidar sensor uses laser to scan the surrounding environment of the unmanned vehicle and generates point cloud data. Through the point cloud data, the control system of the unmanned vehicle can conven...
