Title:
OBJECT TRACKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/215409
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an object tracking device that generates a trajectory of an object within a measurement range, wherein a highly accurate trajectory can be generated by correcting detection frame information on the object. An object tracking device (100) of the present invention generates a trajectory of an object within a measurement range of a camera (2), and is characterized by comprising: an object detection unit (4) which detects an object in each of a plurality of frames acquired by a sensor; a detection frame reliability calculation unit (8) which calculates the reliability of the detection frame on the basis of inter-frame flow information on the detection frame in which the object is detected; a detection frame position correction unit (9) which corrects detection frame information on a low-reliability detection frame by using detection frame information on a high-reliability detection frame; and a trajectory generation unit (10) which generates a trajectory of an object by using corrected detection frame information.
