Abstract

The present invention provides a sensing data acquisition method and device. The method first acquires the relative position information and sensing range information of multiple sensing units, thereby determining the sensing overlapping information of each sensing unit and other sensing units, and then corresponding to each sensing unit. In the cache unit, obtain the total perception data of the perception unit in the perception cycle, match the total perception data in each cache unit according to the perception overlap information, obtain the sub-perception data corresponding to each perception object, and generate the perception data corresponding to each perception object Set, and finally process each sub-perception data in the target perception data set to obtain the target perception data of the target perception object. The invention realizes fusion perception between different vehicles, between vehicles and roadside sensing units, and between different roadside sensing units, makes up for the defect that single-vehicle sensing is prone to blind spots, increases the sensing range, and overcomes the problem of distributed system data The delay problem in transmission improves the quality of perception data.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a method and device for acquiring perception data. Background technique [0002] At present, in the field of autonomous driving, bicycles are mainly used to perceive the environment such as obstacles to obtain environmental perception data. However, when using single-vehicle sensing, there will be perception blind spots, making the sensing data not comprehensive enough, and when obtaining the sensing data of each vehicle, there is also the problem of transmission delay in the distributed system, which will also make the obtained sensing data not ideal. [0003] Therefore, existing sensing data acquisition methods have technical problems of poor sensing data quality and need to be improved. Contents of the invention [0004] The present invention provides a sensing data acquisition method and device to alleviate the technical problem of poor sensing data quali...
