The invention discloses a data acquisition method and device for an unmanned vehicle. The method in a specific embodiment comprises the steps of: selecting a sensor having the highest important levelfrom at least one sensor of the unmanned vehicle as a first sensor and selecting at least one sensor not including the first sensor to form a second sensor set; acquiring the starting time of the current time window and performing the following data processing step: timely acquiring and storing data packets acquired by each of the at least one sensor after the starting time of the current time window; determining whether one condition in the following condition group is satisfied; in response to the determined satisfied condition in the condition group, setting the starting time of the currenttime window as current time, and continuing to perform the data processing step. This embodiment realizes alignment storage of data packets acquired by the at least one sensor of the unmanned vehicle.
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. In order to obtain more and more comprehensive information, unmanned vehicles are usually equipped with a variety of sensor devices. Different sensor devices can complement each other to provide richer information for the perception of the unmanned vehicle control system. The types of sensors commonly configured in unmanned vehicles include lidar sensors, camera sensors, GPS (Global Positioning System, Global Positioning System) and the like. [0003] Although multi-sensors can enable the control system of unmanned vehicles to have richer information, it also brings a certain degree of complexity. Data from diff...
