Identification method and identification device of state of signal lamps

Abstract

The invention provides an identification method of the state of signal lamps. The identification method comprises the steps that A) an area where the signal lamps are placed in an image is selected as a detection area, and the image of the selected detection area is collected; B) single signal lamps are positioned in the image of the detection area; C) the color attributes of the single signal lamps are calculated to determine the colors of the single signal lamps; D) the state of a whole signal lamp is determined through logic judge, if the first color state of the whole signal lamp is stable, when the state of the signal lamp is of a first color, the first color is output, when the state of the signal lamp is of a second color or a third color, the color attribute of the signal lamp is judged through the time series and the space relative position of the signal lamp, and the corresponding color is output; E) the state of the whole signal lamp is output.

Description

technical field [0001] The invention relates to the traffic field, in particular to a method and device for identifying the state of a signal light. Background technique [0002] At present, with the improvement of people's living standards, automobiles have become people's means of transportation, and the number of vehicles on the road is increasing day by day. During driving, the driver needs to drive the vehicle according to the traffic lights on the road. In order to effectively monitor whether the driver obeys the traffic rules, in the existing traffic monitoring system, detection equipment is usually set up to detect the color of the traffic signal light, and know the light status of the signal light, so as to judge whether the vehicle can pass, so as to send the information to the capture device Provide a trigger signal for violating the rules and regulations. [0003] The early electronic police system mainly obtained the status of the signal light by connecting th...

AI Technical Summary

Problems solved by technology

[0003] The early electronic police system mainly obtained the status of the signal light by connecting the control device of the signal light, but this method increased the difficulty of implementation and the cost of the project, so it was gradually replaced by the video-based method in recent years

[0004] In the actual environment, due to the limitation of illumination changes and camera hardware, the image of signal lights sometimes has a serious color cast problem, and the red light is yellowish and the yellow light is reddish. This situation brings difficulties to the identification of signal lights, thus Make traffic monitoring problematic
