Title:
TARGET TRACKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/030800
Kind Code:
A1
Abstract:
In the present invention, a multiple-target-tracking processing unit (40) uses observed values generated by an observed value extraction unit (20) to determine estimated position characteristic values for a plurality of targets using a set position estimation method. Further, the multiple-target-tracking processing unit (40) determines whether there is degeneration in the observed values on the basis of the estimated position characteristic values. If the multiple-target-tracking processing unit (40) determines that there is degeneration in the observed values, a degeneration resolution unit (50) determines estimated position characteristic values for the plurality of targets by using a position estimation method in which a target for a single observed value is estimated on the basis of predicted values for the plurality of targets. The multiple-target-tracking processing unit (40) uses the estimated position characteristic values determined by the degeneration resolution unit (50) to update the path of a correlation hypothesis determined to have observed value degeneration.
