Abstract
The present disclosure provides an object tracking method and an object tracking device. The object tracking method is applied to an image capturing system which includes at least two cameras having image capturing areas at least partially overlapped. The object tracking method includes: obtaining images captured by the at least two cameras, respectively; and respectively identifying objects in the images captured by the at least two cameras; obtaining a feature value of each object, and calculating a position of each object in each image in a global coordinate system; when there are two objects, which are respectively in the images captured by the at least two cameras and have an overall difference value being less than a threshold, counting the two objects as an identical object; wherein the overall difference value is a value determined according to a feature difference value and a position difference value of the two objects.
