Method for judging opening and closing states of high beam of vehicle driving at night

Abstract

The invention discloses a method for judging opening and closing states of a high beam of a vehicle driving at night. The method comprises the following steps of shooting up a lamp polarizing and filtering image of the driving vehicle; extracting the lamp area from the polarizing and filtering image processed in the previous step; according to the mounting position of a camera, determining an effective monitoring area of a road; carrying out opening operation processing on the extracted and processed lamp image, and completing labeling; determining the lamps of the same vehicle; judging whether the lamps of the same vehicle are in a high beam state, wherein, when a condition 1 and a condition 2 are simultaneously met, the high beam of the vehicle is in the opening state, or else, the high beam of the vehicle is in the closing state; and repeating the previous steps, until completing all judgments of all vehicles. The method is suitable for the illumination environments of different road lamps at night, the non-light area is inhibited through the polarizing and filtering method, and the vehicle of which the high beam is opened can be accurately determined by subsequently extracting the features of the high beam.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic monitoring, and relates to a method for judging the on state of high beam lights of vehicles running at night. Background technique [0002] Video surveillance mode has been widely used as a means of obtaining and analyzing traffic conditions in building intelligent transportation systems. For vehicles driving at night, turning on the headlights to illuminate the road is the basis for safe driving. However, the abuse of high beams will cause the driver of the other vehicle to completely lose sight of the road ahead when passing cars and is prone to car accidents. The use of lights is a necessary means to ensure traffic safety. [0003] It is an effective method to analyze whether the driving vehicle turns on the high beam by using the video frame image. However, because the surrounding environment is very different when the vehicle is driving at night, for example, some street lights...
