Title:
MOVING OBJECT DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/017592
Kind Code:
A1
Abstract:
A moving object detecting device (4) repeatedly acquires, from a radar device (2), observation point information indicating an observation point position, which is the position of an observation point at which a radar wave has been reflected. On the basis of the observation point positions indicated by a plurality of items of observation point information acquired at mutually different times, and a tracking filter coefficient representing a degree of tracking to each observation point position, the moving object detecting device estimates a tracking trajectory tracking the movement of a moving object corresponding to a plurality of observation points. The moving object detecting device determines whether the plurality of observation points are distributed in a manner that is continuously biased to one side of the tracking trajectory, sandwiching the tracking trajectory. If it is determined that the plurality of observation points are distributed in a biased manner, the moving object detecting device sets the tracking filter coefficient such that the tracking degree is greater than if the plurality of observation points are determined not to be distributed in a biased manner.
