METHOD FOR DETECTING OBJECT TRAVELING DIRECTION

摘要

There is provided an object traveling direction detection method capable of effectively detecting an object traveling direction with little information. The object traveling direction detection method generates a lightness image from two color images obtained at a predetermined time interval and scans an n x n template (105) on the lightness image of the preceding time t so as to detect the position where the object exists. Next, around the pixel of the position where the object has been detected, pixel values are stored in the template (105). The template (105) containing the pixel values is scanned for the lightness image of time t+1 so as to detect a pixel matched with the pixel values of the template (105). After this, at the pixel position matched with the template (105) on the lightness image of t+1, the object is plotted for each traveling direction so as to generate a traveling direction extraction image.
