Abstract
The present invention discloses a fast object position detection device and a method thereof, particularly to a detection device and a method thereof which can directly apply to various image systems. The device of the present invention mainly comprises an image capturing system that captures images within the regions defined by the user, and an image processing unit determining the position of an object and obtaining related information. In the method of the present invention, a captured image is converted into 1-D distance-axis signal information; a differential value of the 1-D distance-axis signal information is used to determine a position of an object; and a difference of the 1-D distance-axis signal information of at least two adjacent time points is used to determine an approaching status of an object.
