METHOD AND DEVICE FOR DETECTING OBJECT MOVEMENT

PROBLEM TO BE SOLVED: To process an image picture for detecting movement of an object in a scene without previously acquiring knowledge about the type (a shape or other properties) of an object, confirming the object, requiring numerous calculation time, or a large-scale computing means. SOLUTION: W...

Zusammenfassung:	PROBLEM TO BE SOLVED: To process an image picture for detecting movement of an object in a scene without previously acquiring knowledge about the type (a shape or other properties) of an object, confirming the object, requiring numerous calculation time, or a large-scale computing means. SOLUTION: When reverse perspective mapping is carried out on a plurality of scene images 21 photographed by a camera 1, a movement map 26 is generated based on predetermined information around a stationary object in the scene and the color intensity change between corresponding pixels of a transformed image. According to the map, the method and device for detecting object movement can show the position of a moved object. COPYRIGHT: (C)2008,JPO&INPIT
