Anti-glare method for street lamp camera

Abstract

The invention belongs to the field of photography, and discloses an anti-glare method for a street lamp camera. The method comprises the following steps: according to a lamp structure, the location relationship between LED modules and a camera to be detected, and the distance between a light-emitting center of each LED module and the camera to be detected, selecting a structure type of lens hoods, so as to obtain a 3D model of the lens hoods; obtaining a scattering model of the camera to be detected; carrying out scattering simulation to calculate the intensity of illumination on an image-sensitive element of the camera to be detected, the total integrated scattering (TIS), and the image contrast or a PST value of the camera; according to the intensity of illumination, the TIS, and the image contrast or the PST value of the camera obtained through the scattering simulation, judging whether the structure type, the heights and the inclinations which are selected for the lens hoods meet the requirements or not; and according to the structure type, the heights and the inclinations which are selected for the lens hoods, determining the structure type, the heights and the inclinations of the lens hoods, and carrying out productization of the lens hoods. The anti-glare method provided by the invention can be widely applied in the fields of designing and manufacturing of various security street lamps.

Description

technical field [0001] The invention belongs to the field of photography devices, and in particular relates to an anti-glare method and device specially used for a photography device integrated with a fixed lighting device. Background technique [0002] With the advent of the era of intelligent, convenient and efficient information perception, "Smart Street Light", as an expandable and value-added urban smart network system, is used in the Internet of Vehicles, urban environmental monitoring, urban convenience services, government announcements and other platforms. play a huge role in construction. The successful release and commercialization of the "smart street light" solution can effectively promote the construction of smart cities, bring seamless wireless network experience to urban residents, and accelerate the arrival of the era of wireless full connection. [0003] "Smart street lamp" also integrates functions such as micro base station, Wi-Fi, LED, camera, charging ...

Problems solved by technology

[0008] However, in the above technical solution, how to quickly select the appropriate hood structure and parameters according to the different mechanical structure parameters of the lamps, so as to effectively reduce the stray off and reflected light of the image sensor unit of the image sensor, reduce glare, and improve video performance. Picture quality, there has been no ideal solution, the structure and parameters of the hood can only be determined through actual manual experiments, which is inefficient, especially when the structure of the lamp structure or the layout structure of the LED module or the size of the mechanical structure changes When it is difficult to quickly find the most suitable structure and parameters of the hood, it brings difficulties to the design and manufacture of street lamps
