Description

Technical Field

[0001] This utility model relates to the field of crop measurement technology, and in particular to a leaf width acquisition auxiliary device. Background Technology

[0002] The traditional method for obtaining the leaf width of plants such as corn and sorghum is to measure it manually. That is, a person holds a ruler horizontally across the widest part of the leaf and observes it to obtain the leaf width, which is then recorded manually. However, this method of manual measurement and recording is less effective when a large number of leaf widths need to be collected.

[0003] Existing technologies include methods for automatically obtaining blade width using automatic recognition technology. Specifically, image acquisition devices such as cameras are used to photograph the blades to obtain image information. The acquired blade images are then imported into a computer, where automatic recognition software identifies the blade width. This allows for the rapid acquisition of the widths of a large number of blades by importing a large number of images simultaneously. However, in existing technologies, there is no dimensional reference in the acquired images, leading to a significant error between the obtained blade width and the actual blade width. Summary of the Invention

[0004] In view of the above-mentioned technical problems existing in the prior art, the embodiments of this utility model provide a blade width auxiliary acquisition device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of this utility model is as follows: A blade width assistive acquisition device includes: a first plate, the first plate being used to attach to the outer surface of a blade; wherein: The first plate has a reference window with a known length, the length of which corresponds to the width of the blade, and the reference window is used to expose the widest area of ​​the blade, including its two sides; the surface color of the first plate is different from the surface color of the blade.

[0006] Preferably, it further includes a second plate; the first plate and the second plate are pivotally connected on one side in the length direction, so that the first plate and the second plate can be opened and closed by pivoting, and the blade is clamped by closing the first plate and the second plate; the reference window exposes the second plate so that the area of ​​the second plate at the reference window serves as the background of the blade; the extension of the second plate is different in color from the first plate and the blade.

[0007] Preferably, the first plate and the second plate are respectively provided with two magnetic sheets that can attract each other so that the first plate and the second plate can form an attraction when closed.

[0008] Preferably, the four sides of the first plate are flush with the four sides of the second plate; wherein: The first plate has notches at all four corners, which expose the corner areas of the second plate.

[0009] Preferably, the notch has a vertex.

[0010] Preferably, the notch is a rectangular notch.

[0011] Preferably, the surface of the first plate is blue, and the surface of the second plate is red.

[0012] Preferably, reference scale lines are arranged in the middle area of ​​the two long sides of the reference window.

[0013] Preferably, both the first plate and the second plate have two through holes, and a ring passes through the through holes of the first plate and the second plate to form a pivot connection between the first plate and the second plate.

[0014] Preferably, both the first plate and the second strip are made of plastic sheet cut from plastic sheet.

[0015] Compared with the prior art, the beneficial effects of the blade width auxiliary acquisition device disclosed in this utility model are: Since the length of the reference window is known, the width of the blade exposed in the reference window can be obtained more accurately based on the ratio of the blade to the reference window, thus making the blade width less affected by the shooting angle, shooting position and image size.

[0021] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0022] An embodiment of this utility model discloses a blade 100 width auxiliary acquisition device, which is used to assist a camera in acquiring an image of the blade 100 with a reference size.

[0023] like Figure 1 As shown, the device includes a first plate 10 and a second plate 20. Both the first plate 10 and the second plate 20 are rectangular strips, and the length and width of the first plate 10 and the second plate 20 are the same. In use, the first plate 10 and the second plate 20 are stacked with their sides aligned. The first plate 10 and the second plate 20 are pivotally connected on one side along their length. Specifically, through holes 31 are provided in the length direction of the first plate 10 and the second plate 20, allowing a ring 30 to pass through the through holes 31 of the two plates. Thus, the first plate 10 and the second plate 20 can be opened and closed by means of the ring 30. In use, the two plates are in the open state, with the first plate 10 located on the front side (outer surface side) of the blade 100 and the second plate 20 located on the back side of the blade 100. Then, the two plates are closed, thereby clamping a portion of the blade 100 in the width direction between the two plates.

[0024] A reference window 11 is provided on the first plate 10. The reference window 11 is a rectangular window. The length direction of the reference window 11 is consistent with the width direction of the blade 100. By adjusting the relative position between the two plates and the blade 100, the widest area of ​​the blade 100 is exposed in the reference window 11, and the two sides of the widest area of ​​the blade 100 are also located in the reference window 11. The length of the reference window 11 is known.

[0025] After exposing the widest area of ​​the blade 100 to the reference window 11, a camera is used to take a picture of the blade 100 to obtain image information including the widest area of ​​the blade 100 and the device. When the image information is imported into the electronic device and the width parameter of the blade 100 is obtained using a visual recognition application, since the length of the reference window 11 is known, the width of the blade 100 exposed in the reference window 11 can be obtained more accurately based on the ratio of the blade 100 to the reference window 11, so that the width of the blade 100 is less affected by the shooting angle, shooting position and image size.

[0026] In some preferred structures, notches 12 are cut out at the four apex corners of the first plate 10. These notches 12 are rectangular notches with apex 12. By cutting notches 12 on the first plate 10, the second plate 20 is exposed at the apex corners. In this way, the acquired original image can be cropped based on the apex 121 of the rectangular notch 12, so that all images have a uniform standard and less useless information. This avoids interference with the analysis and calculation of the width of the blade 100 due to the presence of interfering information in the image.

[0027] In some preferred configurations, the first plate 10 is configured as blue and the second plate 20 is configured as red, so that the background exposed to the reference window 11 extends to the red provided by the second plate 20, while the blade 100 is essentially green, thereby allowing the edges of the blade 100 in the image to be clearly displayed.

[0028] In some preferred structures, magnetic sheets 40 are attached to corresponding areas of the first plate 10 and the second plate 20. After the first plate 10 and the second plate 20 are closed, the two magnetic sheets 40 attract each other to prevent the two plates from opening automatically. This is beneficial for positioning the blade 100 to prevent the blade 100 from moving.

[0029] In some preferred configurations, reference scale lines 13 are arranged in the middle area of ​​the two long sides of the reference window 11. In this way, the main vein 101 of the blade 100 is adjusted to be aligned with the reference scale lines 13, thereby forming a unified positioning standard between the blade 100 and the instrument, which is beneficial to making the image information regular.

[0030] In some preferred configurations, both the first plate 10 and the second plate 20 are made of plastic sheet cut from plastic sheet.
