Abstract

The invention relates to the technical field of automatic driving, and provides a target data fusion method and system. The target data fusion method described in the present invention includes: time-synchronizing the target attributes detected by each sensor, and respectively storing the original target attributes that have not undergone the time synchronization and the synchronized target attributes that have undergone the time synchronization; synchronizing target attributes to perform target association; and after the target correlation, performing attribute fusion on the target attributes detected by different sensors in the same target based on the original target attributes. The present invention adopts a time-synchronous manner to carry out target association, which improves the accuracy of the target association, and adopts a time-asynchronous manner to fuse the attributes of the associated targets, thereby ensuring the authenticity of the original sensor attributes.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a target data fusion method, system and machine-readable storage medium. Background technique [0002] At present, self-driving vehicles have begun to be gradually introduced to the market, which has greatly promoted the development of intelligent transportation. During the driving process, the self-driving vehicle needs to use various sensors installed on the vehicle body to detect the data of the surrounding environment objects, so as to realize the control of the vehicle and the planning of the path according to the data of the surrounding environment objects. In this process, it is necessary to perform data fusion on the target data detected by different sensors to improve the data accuracy of the target data. [0003] In the development process of autonomous driving data fusion algorithms, time information is the benchmark information for data fusion. Thro...
