Abstract

The invention belongs to the technical field of multi-sensor information fusion, and provides a logic-based trajectory initiation method, system, electronic device and storage medium, forming a tentative trajectory set by using the measurement sets of the first two scanning cycles, and using the third The measurement set of a scanning cycle analyzes the tentative trajectories in the tentative trajectories set, confirms the new trajectories, and finally obtains the state estimation and covariance estimation of the new trajectories, thereby reducing the false alarm rate and effectively solving the problem of starting a new trajectory. problem, the invention can be used in the field of multi-target tracking, and has strong practicability.

Description

Technical field [0001] The present invention belongs to the field of multi-sensor information fusion technology, in particular to a logic-based trajectory initiation method, system, electronic device and storage medium. Background [0002] The main task of trajectory initiation is to use sensor measurements in multiple different scan cycles to detect new targets that appear in the observation space and start their trajectories. At present, the commonly used trajectory initiation method is the rule-based trajectory initiation method, but the false alarm rate of this trajectory initiation method is high. How to reduce the false alarm rate and effectively start a new trajectory is a key technical problem that needs to be explored and solved at present. Contents of the Invention [0003] The present invention provides a logic-based trajectory initiation method, system, electronic device and storage medium, designed to solve the problem of high false alarm rate in the commonly used t...
