Portable intelligent document image collecting system and method based on computer vision

Abstract

The invention discloses a portable intelligent document image collecting system based on computer vision. The system comprises a document image collecting terminal and an image data comprehensive processing terminal. The document image collecting terminal comprises a portable foldable imager, an image pre-processing module, an imaging parameter adjustment response module and a data transmission management module. The data transmission management module is used for transmitting data to a host, wherein the data are collected through the imager and are pre-processed. The image data comprehensive processing terminal comprises an analysis processing layer which comprises a vision development base, a quick edge detection module, a Hough transform detection module, an image geometrical information analyzing module, an intelligent scene setting module, an automatic excerpt rectification module, an intelligent continuously-shooting module and an image storage module. The invention further provides a portable intelligent document image collecting method based on the computer vision. The system and method is high in imaging speed, small in occupied space and high in imaging quality.
