移動物状態量推定装置及びプログラム

Document Type and Number:

Japanese Patent JP7207050

Kind Code:

B2

Abstract:

To accurately calculate a state quantity of a mobile object while taking a detection frequency into consideration even in a case where the number of multiple asynchronous sensors is undefined.SOLUTION: A sensing result acquisition section (14) acquires a detection result of detecting multiple mobile objects by an undefined number of multiple sensors. A mobile object state quantity prediction section (18) predicts, for each of the multiple mobile objects, a state quantity of the mobile object using state quantities stored in a mobile object state quantity storage section (16). A mobile object state quantity alignment section (20) makes the predicted state quantity of the mobile object correspond to the detection result of each of the multiple mobile objects each time the detection result is received by the sensing result acquisition section (14). A mobile object detection frequency prediction section (21) predicts detection frequencies of the mobile objects which are detected by the multiple sensors. A mobile object state quantity erasure section (22) erases a state quantity smaller than the detection frequencies which are predicted by the mobile object detection frequency prediction section (21).SELECTED DRAWING: Figure 2
