[0006] An intelligent recognition terminal for entry-exit documents, including a document recognition reader housing, a glass cover plate is detachably connected to the surface of the document recognition reader housing, a U-shaped pressing strip is fixedly connected to the surface of the document recognition reader housing, the glass cover plate is located below the U-shaped pressing strip, a reflector and a main board are arranged inside the document recognition reader housing, the reflector is located on the bottom wall of the inner cavity of the document recognition reader housing, and the reflector is inclined, a camera is fixedly connected to the top wall of the inner cavity of the document recognition reader housing, and the camera is inclined, and an LED light strip is fixedly connected to the bottom wall of the inner cavity of the document recognition reader housing, and the LED light strip is located below the camera.
[0007] As a further scheme of the utility model: the glass cover plate is subjected to a coating treatment, and an oblique cut angle is provided on the side wall of the glass cover plate.
[0008] As a further scheme of the utility model: two groups of polarizing films are fixedly connected to the inner side wall of the document recognition reader housing, and the polarizing films are respectively located in front of the camera and behind the LED light strip.
[0009] As a further scheme of the utility model: a foot pad is fixedly connected to the lower surface of the document recognition reader housing, and the foot pad is made of rubber material
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. The glass cover plate is coated to improve the light transmittance, reduce the reflection of the front surface of the glass cover plate on the illumination light, and prevent double images. A polarizing film is added behind the LED light strip, and a polarizing film perpendicular to the direction behind the LED light strip is added in front of the camera, which can compress stray light and further improve the imaging clarity. When in use, the document is placed on the glass cover plate. The white light of the LED light strip is irradiated onto the glass cover plate through the reflector. The document image placed on the glass cover plate is reflected by the reflector and enters the camera, so as to take a picture. The main board processes and identifies the text on the document in the image captured by the camera, and interprets the encrypted content of the document, so as to realize document identification and ensure work efficiency.
