Double-sided scanning device and double-sided scanner with mutual scanning backgrounds

Abstract

The invention puts forward a double-sided scanning device and double-sided scanner with mutual scanning backgrounds. The scanner comprises a first scanning assembly, a second scanning assembly, a first backlight plate assembly and a second backlight plate assembly, wherein the first scanning assembly and the second scanning assembly are located on the two sides of a channel to be scanned respectively, the first backlight plate assembly is arranged on the second scanning assembly, the second backlight plate assembly is arranged on the first scanning assembly, a first light inlet is formed in the first scanning assembly, a second light inlet is formed in the second scanning assembly, the first scanning assembly and the second scanning assembly move in the same direction and at the same speed, the first scanning assembly and the second scanning assembly are staggered in the moving direction, thus, the first light inlet is aligned with the first backlight plate assembly, and the second light inlet is aligned with the second backlight plate assembly. According to the scanner disclosed in the invention, the uniformity and brightness of the background color of the scanned image are effectively ensured, and the quality of the scanned image is improved.

Description

technical field [0001] The invention relates to the technical field of scanning equipment, in particular to a double-sided scanning device and a double-sided scanner which serve as scanning backgrounds for each other. Background technique [0002] At present, alternate scanning is often used to detect grain samples by double-sided scanning, which takes a long time to scan, and because the backlight is fixed, when the brightness of the light source is insufficient, the lighting effect is inconsistent with the movement of the scanner corresponding to the backlight, and the As a result, the background of the scanned image is not uniform, which increases the difficulty of algorithm processing and will have a negative impact on the results. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a double-sided scanning device and a double-sided scanner that serve as scanning backgrounds fo...
