Description

Interrupt track association method and device, storage medium and electronic equipment Technical Field The present application relates to the field of computer technologies, and in particular, to a method and apparatus for associating an interrupt track, a storage medium, and an electronic device. Background In the field of radar data processing, tasks such as target tracking, situation awareness, information fusion and the like are particularly dependent on track segment association, and if a track is interrupted, the tasks can be affected very badly, so that huge losses are caused. There are many reasons for causing the track break, such as high-speed maneuvering of the target, intentional stopping of the target, low probability of detection by the sensor, long sampling interval of the sensor, clutter, electromagnetic interference, and the like. The existing interrupt track association schemes mainly comprise two types, namely, track prediction is carried out by depending on track information before interrupt, then feature similarity calculation is constructed on the predicted track and the newly obtained track information, and the second type is that feature similarity calculation is directly carried out on features before track interrupt and the newly obtained track. However, the first approach to track interruption is severely dependent on the accuracy of track prediction, and cannot predict the track very accurately due to the mobility of the target, errors of the measuring tool, etc., especially the track prediction based on kalman filtering, and once new heading information is lacking, the track cannot be predicted. The second method for interrupting the track is mainly to construct the behavior characteristics of the target and analyze the behavior characteristics before and after the track interruption to calculate the track similarity, and because of the diversity of the scenes of the target and the difficulty in generalizing the characteristics, the similarity calculation result is not accurate enough, and the interrupted track cannot be accurately associated. Thus, the accuracy of existing outage track association schemes is to be improved.
