A multi-angle acquisition supplementary light device for image processing

Abstract

The invention discloses a multi-angle acquisition supplementary light device for image processing, which includes an image acquisition device, a main control board and an image focus processing system. The inside of the control board is provided with a control chip, the signal input end of the control chip is respectively connected with a stroboscopic signal input module and an exposure signal input module, and the output end of the control chip is connected with a stroboscopic signal output module, an exposure signal Output module and RS485 circuit module, the whole device expands the signal input module into two parts, the host computer inside the PC system sends the strobe / exposure flash trigger signal, and the supplementary light control system will output PWM pulse signal or exposure flash when receiving the trigger signal The output signal and PWM signal realize the stroboscopic function of the supplementary light system, and use the RS485 module to realize the parameter revision of the host computer to the supplementary light control system, ensuring that the impact of visible light on image quality is minimized under the condition of sufficient supplementary light.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a multi-angle acquisition light supplement device for image processing. Background technique [0002] As a high-tech technology, the intelligent transportation system can bring huge benefits to the social economy and make better use of the limited traffic resources in the city. Its digital and intelligent means can not only solve traffic congestion, but also Vehicle violation evidence collection, road safety system, toll collection system, etc. have brought great convenience. [0003] The intelligent transportation system is now responsible for the following two important tasks: One is road traffic monitoring: in places with high density of people and traffic, such as stations and road intersections, road information can be monitored in real time, thus saving a lot of police force and saving There are a lot of social resources, and it can investigate and collect evidence in time ...

Problems solved by technology

[0008] (2) In the traditional light source, the performance and working characteristics of HID still need to be improved in the supplementary light system, such as: large volume, high working temperature, easily broken glass protective cover, long-term pollution, difficult light distribution, etc. Since it is a traditional light source, its light distribution design is relatively complicated, and if you want to achieve a good lighting effect, such as: collimation, low light loss and uniform lighting, the installation at any angle often costs a lot

Human eyes and cameras are very sensitive to light uniformity. When the light uniformity is less than 0.65, people will feel obviously dazzled, but xenon exposure flash lamps often cannot meet this requirement and cause light pollution;

[0009] (3) The current supplementary light system mainly uses three types of supplementary light: constant light, strobe light and exposure flash light. When the supplementary light is used at night, it is easy to dazzle the driver and also easily cause the license plate to be overexposed.
