Optical system integrated design method of box-type file shooting instrument and optical system integrated design

Abstract

The invention discloses an optical system integrated design method of a box-type file shooting instrument, which comprises the following steps: firstly, a box body is prepared, a backlight illuminating system is arranged in the box body to a provide diffusing surface light source for the shooting modules of the box-type file shooting instrument, so that light with enough brightness can be provided to a file to be shot, the illuminating effect with uniform brightness can be formed on the surface of the file to be shot, and the shooting effect is improved; secondly, two transparent panels are prepared, and are overlapped or spliced on the top part of the box body in a certain included angle; thirdly, two shooting modules are arranged at the lower surface of the diffusing surface light source, a position on the diffusing surface light resource, corresponding to the vision field angle of the shooting modules, are hollowed-out, the two shooting modules are respectively corresponding to one of the transparent plates, and the light axes of the shooting modules are vertical to the corresponding transparent panels; and fourthly, the light illuminating surface of the diffusing surface light source is an upper surface, the light illuminating surface faces to the transparent plates to illuminate the file to be shot, and the file to be shot is placed on the transparent panels. The invention also discloses an optical system integrated design.

Description

technical field [0001] The present invention relates to a camera, in particular to an overall design method of an optical system of a box-type document camera and an overall design of an optical system obtained by using the design method. The overall design of the optical system uses a diffuse surface light source as a digital camera module The light source effectively solves the problem of traditional light sources interfering with the digital camera module. Background technique [0002] In the existing technology, it is one of the current informatization constructions to input many static information such as paper documents, files, books, and materials into the computer through digital processing, so that it becomes digital information that the computer can process, transmit, and utilize hot job. At present, there are a large number of static information resources printed on paper that need to be input into computer systems through digital processing. Archives at all lev...

Problems solved by technology

However, no matter what lighting method the box-type document camera uses as the light source of the digital shooting module, there is a problem that the strong reflection of the light source on the surface of the transparent panel interferes with the normal operation of the digital shooting module, and this problem is especially serious in a dual camera module / panel system
