Abstract

An object tracking method and an object tracking system are provided. The method includes: obtaining a first relative position vector from a first node to a second node at a first time point; obtaining a first position data of the first node and a second position data of the second node at a second time point; identifying a position variation vector from the first node to the second node based onthe first position data of the first node and the second position data of the second node; and identifying a second relative position vector from the first node to the second node at the second time point based on the first relative position vector and the position variation vector. The method improves the tracking accuracy.

Description

Technical field [0001] The present invention generally relates to an object tracking method and an object tracking system. Background technique [0002] Today, object tracking methods are developed to track moving objects, such as vehicles. For example, these object tracking methods can be used to track moving objects around the vehicle to alert the driver of these objects, and thus avoid potential collisions. However, the current method cannot track objects outside the radar detection range. Summary of the invention [0003] In one embodiment, an object tracking method is provided. The method includes: obtaining a first relative position vector from a first node to a second node at a first time point; obtaining first position data of the first node and second position data of the second node at a second time point; based on The first position data of the first node and the second position data of the second node identify the position change vector from the first node to the se...
