Zebra crossing comity behavior detection method based on vehicle-mounted automobile data recorder video

Abstract

The invention discloses a zebra crossing comity behavior detection method based on a vehicle-mounted automobile data recorder video. The method comprises the following steps: step (1), setting a trapezoidal zebra crossing detection area F in a vehicle advancing direction of a video image; step (2): detecting whether the vehicle moves forward; (3) if the vehicle does not move forward, returning tothe step (2), otherwise, executing the step (4); step (4), detecting whether a zebra crossing exists in the area F or not; step (5), if no zebra crossing exists in the area F, returning to the step (2), otherwise, executing the step (6); step (6), detecting whether a person is on the zebra crossing or not; step (7), if no person exists on the zebra crossing, returning to the step (2), otherwise, executing the step (8); step (8), detecting whether the vehicle is stopped or not; and step (9), if the vehicle stops, judging that the vehicle is a gift pedestrian, otherwise, judging that the vehicleis a non-gift pedestrian. The zebra crossing comity behavior detection method has the advantage that the zebra crossing comity behavior can be effectively detected based on the vehicle-mounted video.

Description

technical field [0001] The invention relates to the technical field of courtesy behavior detection, in particular to a method for detecting courtesy behavior at a zebra crossing based on a vehicle-mounted driving recorder video. Background technique [0002] Zebra crossing courtesy behavior detection is to detect whether there are illegal driving behaviors of non-stop and polite pedestrians when vehicles pass by the zebra crossing in the video. Nowadays, it is mainly used in the video surveillance technology of various traffic intersections. The current zebra crossing courtesy behavior monitoring mainly relies on the installation of high-definition cameras from different angles to shoot fixed zebra crossing areas on fixed roads from different directions, supplemented by accurate infrared speed measurement technology And the license plate recognition technology can accurately identify whether the vehicles passing the fixed road section have driving behaviors that are not poli...

However, the function of the current driving recorder is only to collect video images. Because playing back the driving record video needs to consume a lot of time and energy, people often go back to check the violations in the driving recorder video after a traffic accident has occurred. Traffic accidents have caused irreparable personal injuries to the victims. Therefore, in view of the current characteristics of the continuous increase in the penetration rate of driving recorders, it is urgent to invent a zebra crossing that can effectively detect drivers' zebra crossing courtesy behavior based on the vehicle driving recorder video.
