METHOD FOR DETECTING A MOVEMENT PATH OF AT LEAST ONE MOVING OBJECT WITHIN A DETECTION REGION, METHOD FOR DETECTING GESTURES WHILE USING SUCH A DETECTION METHOD, AND DEVICE FOR CARRYING OUT SUCH A DETECTION METHOD

摘要

In a method for detecting a movement path (2₂₃; 2₂₁, 2₂₂) of at least one moving object (23, 24) within a detection region, the moving object is first detected so as to be imaged. In the process, a first detection image (11) is generated which reproduces the detection region at a first detection time. After a delay period, a second detection image (12) is generated which displays the detection region at a correspondingly later detection time. Correspondences of the image regions (13 to 22) of the detection images (12) are then determined and analyzed. For this purpose, the detection images (12) are compared, a distribution density of image regions (13 to 23) which correspond to one another with respect to their changes in position in the detection image (12) is ascertained, and the ascertained distribution density is analyzed. Pixels (23, 24) with a corresponding movement increment (2₂₃; 2₂₁, 2₂₂) between the detection images (12) are then assigned on the basis of the analyzed distribution density. The pixel movements are then analyzed. The method and a gesture detection method which uses said method can be carried out using simple optical means.
