Abstract

The invention belongs to the technical field of electronic surveillance, and relates to a surveillance camera filtering system and method. According to the system and the method disclosed by the invention, a light filter is switched into an infrared light filter in the daytime, and infrared light can be filtered so as to solve the color cast problem caused by the infrared light in the day time; at night, since visible light brings severe interference to a driver at night, a visible light white-light lamp is forbidden to use for snapshotting, the light filter is switched into an all-pass light filter to allow as much light as possible to enter the surveillance camera; meanwhile, the white-light lamp which emits infrared light and ultraviolet light is used, clearer images can be snapshotted since the infrared light and the ultraviolet light have an obvious light filling effect under a condition of dark light at night, and a license number or specific surveillance characteristics can be better extracted.

Description

technical field [0001] The invention belongs to the technical field of electronic monitoring, and in particular relates to a monitoring camera light filtering system and method. Background technique [0002] Road traffic monitoring is an extremely important part of the traffic system. In the huge road traffic network, there are various traffic participants. The situation on the road changes rapidly, and traffic accidents or accidents often occur. Road monitoring information is an important measure to strengthen road monitoring, improve the efficiency of traffic accident handling, and ensure people's traffic safety. [0003] Road monitoring camera is the core part of road traffic monitoring, and it is the most important link to obtain road and vehicle conditions. How the monitoring camera obtains clear images is the key to the function of the monitoring camera. However, surveillance cameras work around the clock, and different light conditions in different time periods will ...
