MOBILE OBJECT TRACKING PROCESSING METHOD

摘要

PURPOSE:To recognize only a targeting mobile object and to facilitate the tracking of the mobile object even if another new mobile object intrudes into a rectangular area and is recognized as a closed area by changing sprirally the direction in which the presence or absence of a label number is scanned. CONSTITUTION:When the labeling processing is carried out in a rectangular area, the direction in which the presence or absence of a label number is scanned is spirally changed with the centroid point set in the preceding frame defined as a starting point. That is, a mobile object area is segmented in a rectangular frame and the spiral labeling processing is carried out in the segmented rectangular area only. Therefore no influence is caused by the movements of the mobile objects preventing out of the rectangular area. Then a closed area having the smallest distance from the centroid point set by a preprocessing frame is recognized as label number '1'. Thus it is possible to track the targeting mobile object without being affected by the newly intruding mobile objects as long as the distance between the centroid point and an entered mobile object is larger than the distance between the centroid point and the desired mobile object.
