Description

Blade scanner background auto-change over device

Technical Field

The utility model belongs to the technical field of forestry test blade scanning, concretely relates to blade scanner background auto-change over device.

Background

At present, in forestry experiments, a scanner scans blades and generates pictures on a computer in a scanning mode so as to calculate the blade area of the blades by utilizing pixel points or model and estimate the material content of other blades. Present scanner utilizes existing file scanner generally, scan the blade, however the blade is different with the paper, the blade is because the variety of blade is different, the position is different, it is different to gather the season, the blade colour of gathering also is different, some or even differ greatly, lead to when utilizing the scanner scanning, can appear, the condition that is difficult to distinguish the boundary between blade and the background board appears, consequently, the pixel that leads to every picture also is difficult to fix, or the scanning of edge profile, lead to being difficult to carry out accurate calculation to the leaf area.

As shown in FIG. 1, the conventional scanner is used to scan the leaf by simply marking the leaf with the number and position on the A4 white paper and then placing the leaf for scanning. The whole typesetting process is complicated and the handwritten marks are easy to cause ambiguity. If the leaf color and the ground color are close, the problem of unclear boundaries can occur.

Furthermore, clamping grooves are formed in four corners of the upper portion of the fixing plate, rotating clamping pieces are arranged in the clamping grooves, and four corners of the background plate are pressed under the clamping pieces to be fixed.

Furthermore, magnetic sheets are arranged at four corners of the upper portion of the fixing plate, the back of the corresponding background plate is provided with an adsorption magnetic sheet, and the fixing plate and the background plate are fixed through magnetic adsorption.

Further, the thickness of the fixing plate is between 1 and 2 mm; the thickness of the sucker is less than 0.5 mm; the thickness of the card is less than 0.5 mm.

Further, the fixed plate is a plastic fixed plate.

Further, the background plate thickness is less than 0.3 mm.

Further, the background plate is kraft paper plastically packaged by a plastic film, and the back of the marking plate is provided with nano double-sided traceless glue.

Further, the fixing plate and the background plate are magnetic plates, and the mark plate is a magnetic mark plate.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is following: 1. the utility model has the advantages of very simple structure, convenient to use, it is convenient to make.

2. The utility model discloses simplified the process to the blade sequencing, serial number, the mark tablet is clear, has solved the loaded down with trivial details problem of typesetting process.

3. The utility model discloses can be equipped with the background board of multiple difference, be applicable to diversified blade situation, solve the problem on boundary between blade and the background board.

Detailed Description

The present invention will be further clarified by the following embodiments, which are implemented on the premise of the technical solution of the present invention, with reference to the attached drawings, and it should be understood that these embodiments are only used for illustrating the present invention and are not used for limiting the scope of the present invention.

As shown in fig. 2 and 6, the utility model discloses a background switching device of a vane scanner, which comprises a fixed plate 1 and a background plate 2; the size of the fixed plate 1 corresponds to the size of the bottom plate of the existing scanner, the four corners of the bottom of the fixed plate 1 are provided with the suckers 3, and the suckers 3 can be adsorbed on the bottom plate of the scanner. The background plate 2 is fixed on the fixed plate 1; the background plate 2 is provided with various colors according to the experimental requirements, and is suitable for various blade conditions; a movable mark plate 4 is arranged on the background plate 2 (the mark plate 4 comprises variety and position information).

The utility model discloses in, the fixed background board 2's of fixed plate 1 mode includes but is not limited to following several kinds:

in the first embodiment, as shown in fig. 3, 4, and 5, the material of the fixing plate 1 is not limited, the four corners of the upper portion of the fixing plate 1 are provided with the slots 5, the rotating cards 6 are arranged in the slots 5, and the four corners of the background plate 2 are directly pressed under the cards 6 to be fixed.

In the second embodiment, different from the first embodiment, magnetic sheets (not shown) are disposed at four corners of the upper portion of the fixing plate 1, and an adsorbing magnetic sheet (not shown) is disposed at the back of the corresponding background plate 2, and the fixing plate 1 and the background plate 2 are fixed by magnetic adsorption, so that the structure is simple and the operation is convenient.
