Abstract
The present invention relates to a scanning device with a positioning senor and a processing method to obtain images, comprising a casing, linear contact image sensor (CIS), further comprising a system processor Pfor controlling the work of said CIS by timing signal, the optical coordinate sensors and the displacement processor Pand Pfor estimating the coordinate increment () and the coordinate increment () of the real-time displacement, an A/D circuit and data buffer; said system processor Ppackets original scanning data with positioning information (), and then transfers to the upper machine. An image processing module in the upper machine de-packets said original scanning date (); Converts out the coordinate of the terminal pixel of said linear contact image sensor (CIS), and configures the image line in the object image configuring area; and calculates and rectifies the relative offset of the positioning coordinate of the two scanning bands making using of the statistical characteristic of part of pixel data in the overlapped area of the two scanning bands.
