Problems solved by technology

However, since flatbed and drum scanners use fixed devices to complete large-format image scanning, the equipment is bulky and expensive, and it is easy to cause damage to the scanned target, and the thickness and type of the scanned target are limited, and the thickness of the scan is smaller than the maximum paper feed Height, scanning types are generally limited to paper
However, although the hand-held scanner is portable, the horizontal scanning speed is uneven, resulting in low image resolution accuracy, which is lower than 600DPI

Embodiment

[0023] Such as figure 1 As shown, a portable ultra-large-format high-precision scanning device includes a scanner host 1, a scanner slave 3, a roadway 2 and a stepping motor 4, and the scanner host 1 is connected with the stepping motor 4 and is arranged on the roadway 2, scanning The scanner host 1 transmits the collected image information to the scanner slave 3 wirelessly connected to the scanner host 1;

[0024] The roadway 2 is based on the size of the scanning area, using aluminum rods to build the running track, and dividing the scanning area into n blocks. After the scanning is completed, the scanning device is disassembled and folded.

[0025] Each of the n blocks of the tunnel 2 is provided with a stepping motor 4 .

[0026] The scanner host 1 scans n blocks of the roadway 2 in blocks.

[0027] The scanner host 1 includes a main control module 5, an LED driver module 6, a CIS sensor module 7, an AD data acquisition module 8, a wireless transmission module 9 and a st...

Abstract

The invention discloses a portable extra-large-breadth high-precision scanning device. The characteristics lie in that the portable extra-large-breadth high-precision scanning device comprises a scanner master machine, a scanner slave machine, roadways and a stepper motor, the scanner master machine and the stepper motor are connected and arranged on the roadways, and the scanner master machine transmits acquired image information to the scanner slave machine which is wirelessly connected with the scanner master machine. The device disclosed by the invention selects a portable handheld scanner structure, adopts a block image acquisition mode, combines an image splicing technology, adopts a constant current source to drive a sensor five-color light source and adopts the stepper motor to drive transverse constant-speed scanning, thereby realizing portable large-breadth high-precision image acquisition.

Description

technical field [0001] The invention belongs to the technical field of scanners, in particular to a portable ultra-large format and high-precision scanning device. Background technique [0002] At present, large-format scanners at home and abroad are generally divided into three types: flatbed, drum and handheld. However, since flatbed and drum scanners use fixed devices to complete large-format image scanning, the equipment is bulky and expensive, and it is easy to cause damage to the scanned target, and the thickness and type of the scanned target are limited, and the thickness of the scan is smaller than the maximum paper feed Highly, the scanning type is generally limited to paper type. However, although the hand-held scanner is portable, its horizontal scanning speed is uneven, resulting in low image resolution accuracy, which is lower than 600DPI. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior ar...
