Problems solved by technology

However, at night, due to the extremely weak light, the light intensity of the background scene in the monitoring screen is extremely low, and the ratio of the light intensity of the traffic signal light to the light intensity of the background scene far exceeds the dynamic range of the image sensor, resulting in overexposure of the traffic light In some cases, the outline of the traffic light is blurred. Users can only distinguish the color of the traffic light through the color of the halo, but cannot distinguish the specific shape of the traffic light.

Abstract

The invention provides a processing method for a video monitor image. The method comprises the steps of determining area information of a traffic light in a reference monitor image; removing the traffic light in an original monitor image according to the area information to obtain an intermediate monitor image; and optimizing halo around the original traffic light part in the intermediate monitor image to obtain a target monitor image. According to the processing method for the video monitor image, the problem that the outline of the traffic light in a night monitor image cannot be distinguished can be solved, so that a user can clearly distinguish the indication direction of the traffic light, and thereby efficiency and accuracy for identifying traffic violations in later are improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method for processing video surveillance images. Background technique [0002] With the rapid development of video surveillance technology, more and more surveillance cameras are installed at intersections or road sections to monitor violations of motor vehicles such as running red lights and pressing lines. [0003] At present, during the daytime, due to the sufficient light, the surveillance images captured by surveillance cameras usually do not appear to be overexposed. Users can clearly distinguish the color and outline of traffic lights, such as: turn left at a red light and go straight at a green light Wait. However, at night, due to the extremely weak light, the light intensity of the background scene in the monitoring screen is extremely low, and the ratio of the light intensity of the traffic signal light to the light intensity of the background sce...
