Embodiment 1

[0082] refer to Figure 1 to Figure 10 , a low-cost ultra-wide high-speed scanner, including a plurality of cantilever beams 4 with 16 camera units and 17 lighting units composed of area array CCD scanning units for fixed scanning imaging, used to fix and support the cantilever beam The moving bracket 6, the long axis 7 for providing the scanning stroke for the moving bracket, the moving bracket moves on the track specified by the long axis, and is used to connect the camera unit formed by the area array CCD with the computer. card, a computer 12 for processing the images taken by multiple area array CCDs and controlling the drive components to make the mobile bracket move, an LED lighting unit 11 for providing illumination light to the scanning area, and a computer for providing flat Scanning table 3 of the object to be scanned, support bracket 1 for supporting the scanning table, touch screen 14 for human-computer interaction, camera unit 2 for acquiring scanned images, ligh...

Embodiment 2

[0157] refer to Figure 1 to Figure 10 , in this embodiment, the number of camera units used and the resolution of the camera units can be different, and different scanning resolutions can be obtained by changing the resolution of different camera units; the scanning requirements of different widths can be met by adjusting the number of camera units . Other schemes of this embodiment are all the same as in Embodiment 1.

Abstract

The invention provides a superwide-width high-speed scanner with a low cost, comprising a scanning platform for horizontally placing a scanned object. The scanner also comprises a mobile stand movably mounted on a longitudinal track; the mobile stand is connected with a driving part; a transversely placed cantilever beam is mounted above the mobile bracket; multiple image pickup units used for fixedly scanning images and belong to multiple scanning units formed by array CCDs (Charge Coupled Devices) are mounted on the cantilever beam; the multiple image pickup units are arranged in parallel; the scanning platform is positioned under the cantilever beam; the scanner also comprises a computer used for processing images shot by the multiple array CCDs and controlling the driving part so that the mobile stand moves. The superwide-width high-speed scanner provided by the invention has the advantages of wide scanning width, high scanning speed, low manufacturing cost and the like, and is suitable for scanning any plane object.

Description

technical field [0001] The invention belongs to the application of image sensor technology, image processing technology, mechanical transmission control technology and computer technology in the field of image scanning, in particular to a low-cost ultra-wide and high-speed scanner. Background technique [0002] Wide-format scanners are used to process original images of various sizes such as large-scale color posters, architectural sketches, detailed maps, and artworks. Applications. Evaluation of a wide-format scanner often has the following important parameters: 1) scanning speed; 2) scanning accuracy; 3) scanning width; 4) requirements for scanning objects; 5) scanner price; 6) image processing 7) remote real-time interaction capabilities, etc. At present, there are usually only two imaging methods used by large-format scanners, one is CCD (Charge Coupled Device) imaging method, and the other is CIS (Contact Image Sensor) imaging method. The imaging methods of these tw...
