Collect passport image, equipment be it is open, global digital image-forming refers to that CMOS completes entire passport image by single exposure
Collection process.Equipment uses open by design, during Optical System Design, needs to consider the technology of following three aspects
Problem:
Lighting method: reasonable illumination is the guarantee of photo-quality imaging, and illumination needs to consider light angle, brightness of illumination, light
The design of color etc..
Reflective problem: it is reflective, it refers to that the light that light source projects passes through mirror-reflection, is directly entered showing for photosensitive part
As.When this phenomenon occurs, the pixel on the reflective corresponding CMOS in generation part can be saturated, to keep image quality bad
Change.Now, envelope modeling, easily generation mirror-reflection have been carried out in a large amount of passport page.
Ambient light interference problem: the reflective phenomenon for caused by single light source can simply change incident angle and avoid sending out
It is raw, but under the conditions of complex illumination, the interference of external light source is difficult to avoid.
Utility model content
The purpose of this utility model is to provide a kind of novel passport recording devices, it is intended to solve to occur when passport typing
The problem of lighting quality, reflective and ambient light interference.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of novel passport recording device, including top cover, lower cover, light source board, imaging modules, column, base upper cover and bottom
Seat lower cover, the light source board are fixedly mounted between top cover and lower cover, and the column both ends connect with lower cover and base upper cover respectively
It connects, pedestal lower cover is fixedly connected with base upper cover, and the imaging modules are mounted in the groove of lower cover, imaging modules and light source board

It connects.
In above scheme, the wide-angle lens selects the wide-angle lens of 8mm equivalent focal length.
In above scheme, it is the LED light of 630nm that the LED light, which selects wavelength,.
The novel passport recording device of the utility model, by the wide-angle lens of equivalent focal length, in visual field range foot
Shooting distance can be shortened under conditions of enough, to control the volume of integral device；Light source emission shaft is parallel with lens principal axis, refers to
Passport placement region in equipment chassis, but caused with passport plane normal at 30 degree of angles to avoid ontology light source reflective；It is double
Mouth magazine structure has 30 degree of inclinations that can cover 90% towards imaging modules wherein positive imaging modules read opening with bottom surface
The character for needing to read on passport is only exposed to imaging modules by above ambient light interference.
