Abstract
An object tracking device and object tracking method that can track an object accurately without increasing the computational load are provided. An object tracking device () includes an input interface (), a processor (), and an output interface (). The input interface () is configured to acquire sensor data. The processor () is configured to detect a detection target from the sensor data and track the detection target using Kalman filters associated with each of the detection target and an observed value. The output interface () is configured to output a detection result regarding the detection target. The processor () is configured to execute a first process to select a Kalman filter with low certainty from among a plurality of the Kalman filters associated with the same detection target or observed value as an exclusion candidate Kalman filter that could be excluded from the association, and a second process to exclude from the association and initialize the exclusion candidate Kalman filter that meets an initialization condition.
