[0003] The inventors found that in order to improve the success rate of license plate capture in view of insufficient light, most of the prior art is to install a supplementary light at the position of the capture camera. The direction is mainly divided into the front direction and the rear direction; however, due to the lack of light in this way, it is very easy to cause the driver and passengers, especially the driver, to form a "black hole" or "white hole" effect within a certain period of time, unable to see Clear the situation ahead of the road, which brings great potential danger to road safety
With the rapid development of my country's smart roads, the demand for license plate capture is increasing day by day, so the existing way of supplementary light poses a huge challenge to road traffic safety

Embodiment 1
[0033] The purpose of this embodiment is to provide an intelligent lighting method for license plate capture.
[0034] An intelligent lighting method for license plate capture, including:
[0035] Divide the lighting area into a gradually increasing lighting area, a stable lighting area, and a diminishing lighting area, and set up corresponding lighting devices in different areas;
[0036] When the brightness of the natural environment in the lighting area does not meet the license plate capture requirements, the lighting device works, otherwise, the lighting device does not work;
[0037] The vehicle passes through the gradually increasing lighting area to reach the stable lighting area. The license plate capture facility captures the license plate. After the vehicle passes through the stable lighting area, it drives away through the faded lighting area.
[0038] Further, the crescendo lighting area is the area where the lighting brightness gradually increases along the driving directi...
Embodiment 2
[0042] The purpose of this embodiment is to provide an intelligent lighting system for license plate capture.
[0043] Such as figure 2 As shown, a schematic diagram of the signal relationship of an intelligent lighting system for license plate capture is shown; an intelligent lighting system for license plate capture includes:
[0044] An intelligent lighting system for capturing highway license plates includes an integrated management subsystem, a remote data transmission subsystem, and an outfield facility subsystem;
[0045] The remote data transmission subsystem includes the remote transmission equipment of the field, the central office transmission equipment of the management center, and the transmission channel between them;
[0046] The integrated management subsystem includes integrated management server, management computer, management software, power management equipment and lightning protection grounding equipment; the management software is installed in the integrated ma...

Abstract
The invention provides a license plate snapshot intelligent illumination method and system. According to the scheme, illumination devices are arranged in front of and behind a highway license plate snapshot facility; a snapshot area is divided into a gradually strong illumination area, a stable illumination area and a gradually weak illumination area; when the brightness of the natural environmentaround the road license plate snapshot facility does not meet the license plate snapshot requirement, the illumination devices work, a vehicle passes through the gradually strong illumination area and reaches the stable illumination area, the license plate snapshot facility snapshots a license plate, and the vehicle passes through the gradually weak illumination area and then is driven away afterpassing through the stable illumination area; according to the scheme, the intelligent illumination method is provided for road license plate snapshot through an intelligent detection and control technology, the license plate snapshot success rate under the condition of insufficient light is improved, and the traffic safety problem caused by a light supplementing lamp mode is reduced.
Description
Technical field [0001] The present disclosure relates to the field of smart transportation technology, and in particular to an intelligent lighting method and system for license plate capture. Background technique [0002] The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art. [0003] The inventor found that in order to improve the success rate of license plate capture in the case of insufficient light, most of the prior art is to install fill light at the location of the capture camera. The fill light mostly uses strobe lights or strobe lights in form. The direction is mainly divided into the front direction and the rear direction; but because this method is in the case of insufficient light, it is very easy to cause the drivers and passengers, especially the driver, to form a "black hole" or "white hole" effect within a certain period of time, making it impossible to see Clearing the c...
