Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The embodiments of the present invention can be applied to intelligent traffic systems, and are especially suitable for application scenarios of monitoring and color correction of signal lights. The embodiment of the present invention forms a short-exposure image frame by reducing the exposure time. The signal light color information in the short-exposure frame is relatively complete and realistic, and the background interference ...

Abstract

The invention discloses a signal lamp color correction method, a monitoring method, and a device thereof, and relates to the video monitoring field. The color correction of the distorted image frame of the signal lamp can be realized. According to the invention, the short exposure reference frame and a to-be-processed image frame can be acquired; the short exposure reference frame is shot after the to-be-processed image frame, and the exposure time of the short exposure reference frame is less than the exposure time of the normally shot image frame; the signal lamp foreground area of the short exposure frame can be determined; the color correction of the corresponding area of the to-be-processed image frame can be carried out according to the determined signal lamp foreground area; and therefore the color correction of the distorted image frame of the signal lamp can be realized.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method for correcting the color of a signal lamp, a monitoring method and a device. Background technique [0002] With the development of electronic technology, computer technology, micro-processing technology and new sensor and storage technology, intelligent traffic surveillance cameras have gradually become the mainstream equipment of intelligent transportation due to their advantages of high efficiency and intelligence. made a great contribution. Among them, the traffic signal light (hereinafter referred to as the signal light) monitoring solution uses the intelligent traffic monitoring camera to monitor and shoot the intersection where the signal light is located, and can monitor the vehicles that violate the traffic rules (for example: running the red light), so as to extract the violation evidence of the vehicle that has run the red light phenomenon . [0003] In the pr...
