Detection of a motionless object on intersections of traffic routes

摘要

Image features of a foreground vs. board are made of input video data by means of the application of a background-subtraktionsmaske extracted, and having an optical flow image features are made of a region of the introduction video image data extracted by the extracted image features of the defined foreground vs. board. If estimated motion features indicate that the underlying the subject matter is in motion, a predominant direction of movement of the underlying object is determined. If the prevailing direction of movement parallel to an alignment of the second, crossed route, a event alarm, is pointing to the fact that a motionless the subject matter of the forward movement on the crossing second traffic route are not produced blocked. If the estimated motion features indicate that the underlying object is stationary or that its determined predominant direction of movement is not parallel to the second traffic route, that is, the appearance of the region of the determined and a foreground vs. board bewegungslosigkeits-timer, while the region of the foreground vs. board the extracted motion features of the has foreground vs. board.
