Title:
OBJECT TRACKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/005063
Kind Code:
A1
Abstract:
An observation point extraction unit (31) of an object tracking device (1) extracts an observation point obtained from a target (3) of a current cycle, on the basis of a state amount of the target (3) estimated in the previous cycle. A prediction point generation unit (33) generates a prediction point at a prediction position where the observation point can be expected, on the basis of the state amount of the target (3) estimated in the previous cycle. An alignment unit (35) aligns, through scan matching, the observation point obtained from the target (3) of the current cycle with the prediction point generated by the prediction point generation unit (33). A residual error calculation unit (37) obtains a correspondence point of an object at the prediction position corresponding to the observation point from the prediction point aligned with the observation point obtained from the current cycle, and calculates a residual error between the observation point and the correspondence point.
