Description

Technical Field

[0001] This utility model relates to the field of plant phenotypic information acquisition equipment, specifically to a black box for non-destructive acquisition of crop leaf phenotypic data. Background Technology

[0002] Phenotypic characteristics such as leaf color, shape, and texture can indicate a plant's health status. Healthy leaves are typically bright green and vibrant. Yellowing, wilting, or spotting leaves may indicate disease, nutrient deficiency, or environmental stress. Continuous observation of plant leaf growth can reveal the plant's growth rate, direction, and developmental stage. This is crucial for agriculture, horticulture, and plant research, helping to optimize planting management and predict growth trends. Continuous leaf observation allows for a better understanding and management of plant growth and health.

[0003] Traditional methods typically involve outdoor photography of target plants and their organs using handheld measuring devices. However, this method suffers from poor operational stability, inconsistent photographic environments, and unclear images, especially in low light conditions. Furthermore, significant variations in photographic distance and focal length lead to substantial data errors. Fixed-position measuring devices have also emerged on the market. These devices are bulky and inconvenient for personnel to carry, requiring the removal of leaves before insertion. This method can be destructive to the crop, potentially causing irreversible damage to rare or limited samples.

[0004] To overcome these problems, a non-destructive and efficient method for collecting crop leaf phenotypic data is urgently needed. This method must meet the requirements of a uniform light source and background environment, portability, and non-destructiveness, aiming to overcome the limitations of traditional methods and ensure data accuracy. Only then can it be better applied to crop research, agricultural science, and environmental research, providing strong support for crop improvement, agricultural production, and environmental protection. Utility Model Content

[0005] The purpose of this invention is to provide a black box for non-destructive sampling of crop leaf phenotypes. It has a reasonable structural design, is easy to carry and operate, and does not require the removal of leaves for sampling, which helps to improve measurement accuracy.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A black box for non-destructive sampling of crop leaf phenotypes includes: an opaque box body, a light source, and a light-blocking curtain; the box body is rectangular, consisting of a top plate, a bottom plate, a rear end plate, and two side plates forming a square box structure with a front opening, the front opening being the leaf stem inlet, the top plate having a shooting window, the bottom plate having a plant stem groove, the upper part of the inner wall of the side plates having a light source, and the upper edge of the front opening of the box body having a light-blocking curtain, which can be lowered to cover the front opening of the box body.

[0008] The plant stem channel extends from the front end of the base plate along the center to the center of the base plate, making it convenient for stems with plant leaves to enter the center of the box through the channel. The width of the plant stem channel should be greater than the thickness of the plant stem to ensure that the plant leaves with stems can enter the box smoothly.

[0009] Furthermore, a background card is provided above the bottom plate of the box. The background card is in contact with the bottom plate and is replaceable. The shape of the background card matches that of the bottom plate and is provided with a groove. The shape of the groove is the same as that of the plant stem groove. A stem groove card is provided between the background card and the bottom plate. The width of the stem groove card is greater than the width of the plant stem groove, and the length is less than the length of the plant stem groove. Displacing the stem groove card can close most of the plant stem groove, leaving only a small gap at the inner end of the plant stem groove for the plant stem to pass through.

[0010] Furthermore, rope seats are fixed to the outside of the two side panels. The rope seats are connected by ropes of appropriate length, allowing the black box to be suspended around the user's neck or other areas to ensure stability and safety.

[0011] The aforementioned shooting window is a rectangular window, which facilitates the shooting device to take pictures. It is sufficient to ensure that the shooting lens can capture the inside of the box, thereby facilitating the acquisition of images of the leaves inside the box. The shooting device used in conjunction with this utility model is a camera, mobile phone, or other high-resolution image acquisition device. The shooting device takes pictures of the leaves through the shooting window. The setting of the light source inside the box can ensure that these devices can capture the details and features of the leaves, so as to provide accurate image information for analysis and research.

[0012] The background card and stem groove card are made of non-reflective materials, which can effectively reduce light reflection, avoid interference from the background and light source on the leaf image, and improve the contrast and clarity of the image.

[0013] The light source uses a self-storing lithium battery lamp, and the light source switch is touch-sensitive, which can easily control the light source to turn on. The power supply is installed magnetically, which makes it easy to detach and charge the light source. The light source is placed on the upper side of both sides of the box. The light source has stable illumination characteristics and adjustable brightness to meet different shooting needs and ensure that the leaves are photographed under appropriate lighting conditions.

[0014] The screen is made of high-quality light-blocking material and features a hinged design. The top of the screen is attached to the top panel of the box using Velcro. The length of the screen must exceed the size of the front opening of the box to prevent external light from entering the black box, thereby ensuring the light-blocking effect during the shooting process.

[0015] The beneficial effects of this utility model are: (1) It does not require picking leaves and will not damage the plant itself. The collection can be carried out by moving the box to a suitable position; (2) It is easy to carry and can quickly complete the leaf data collection on site with high collection efficiency; (3) It has good light protection and the brightness of the light source inside the box is stable. Regardless of the influence of external environmental factors of the plant, the black box can provide stable environmental conditions, ensuring the consistency and reliability of the collected data, which helps to improve the accuracy of leaf analysis.

[0022] The present solution will now be described in conjunction with the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1-5. This embodiment of the present invention provides a black box for non-destructive sampling of crop leaf phenotypes. Referring to Figure 1, the black box for non-destructive sampling of crop leaf phenotypes in this embodiment includes: an opaque box body, a background card 10, a light source 7, and a light-blocking curtain 5. A shooting window 4 is provided on the top of the opaque box body, and a plant stem groove 8 is provided on the bottom of the opaque box body. The light source 7 is provided on the upper sides of both sides inside the box body. The stem groove card 9 and the background card 10 are placed on the lower side inside the box body. The stem groove card 9 is pressed between the background card and the base plate. The stem groove card 9 can be easily moved by lifting the background card. The rope 3 is connected through rope seats 2 on both sides of the outside of the box body. One side of the box body is designed as a curtain. As the box body moves actively, the leaves and plant stems enter the box body through the plant stem groove 8 at the lower end of the leaf inlet.

[0024] Using the above implementation method, the opaque black box includes an upper shooting window 4, the size of which should be larger than the lens size of the shooting device. The shooting device is a camera, mobile phone or other high-resolution image acquisition device. The leaf is photographed through the shooting window 4 by hand-held shooting device. These devices can capture the details and features of the leaf to provide accurate image information for analysis and research.

[0025] The stem groove card 9 and background card 10 are made of non-reflective materials. The color of the materials can be adjusted and changed before use according to different needs. These materials can effectively reduce light reflection, avoid interference from the background and light source on the leaf image, and improve the contrast and clarity of the image.

[0026] The opaque black box includes a plant stem channel 8 at the bottom. By moving the box by hand, the plant stems of the plant leaves can smoothly pass through the plant stem channel into the box.

[0027] The rope seats 2 are located on both sides of the black box and are used to fix the rope 3. The rope is of moderate length, so that the black box can be hung around the user's neck or other attachment points to ensure stability when carrying or shooting.

[0028] The internal light source of the black box is an LED lamp, an incandescent lamp, or other suitable light source 7. The light source is placed on the upper side of the box body. The light source has stable illumination characteristics and adjustable brightness to meet different shooting needs and ensure that the leaves are photographed under appropriate lighting conditions.

[0029] The screen 5 is made of high-quality light-blocking material. The screen is attached to the upper part of the box using Velcro 6. The length of the screen must exceed the size of the opening of the black box to prevent external light from entering the black box, thereby ensuring the light-blocking effect during the shooting process.

[0030] Compared with existing technologies, the beneficial effects of this invention are as follows: This non-destructive crop leaf phenotyping black box has significant application value. It is non-destructive, eliminating the need for leaf harvesting. Traditional leaf analysis typically requires harvesting leaves and placing them in a darkroom or black box for imaging. This black box, through improved design and function, allows researchers to directly acquire leaf images from plants without damaging them or harvesting leaves. This non-destructive acquisition method not only reduces interference with plants but also enables continuous monitoring of leaf characteristics of the same plant over time, providing more comprehensive data. Furthermore, the black box is portable; compared to traditional darkrooms and other black boxes, it is compact, lightweight, and easy to carry and set up. Researchers can carry it to different locations such as fields or laboratories. This portability allows researchers to quickly collect leaf data on-site, avoiding the hassle and time delay of bringing samples back to the laboratory, saving significant time and labor costs.

[0031] Meanwhile, the crop leaf phenotypic nondestructive sampling black box ensures uniformity, guaranteeing consistent light source conditions during sampling and avoiding interference and the impact of factors such as different times, light levels, and weather conditions on the data. Through its designed light source system, the crop leaf phenotypic nondestructive sampling black box provides consistent and controllable lighting conditions. Whether in a laboratory or field environment, the black box provides uniform illumination, ensuring that each leaf is sampled under the same lighting conditions. This allows researchers to minimize the influence of light factors on leaf phenotypic characteristics, obtaining more reliable and comparable data. Furthermore, the black box avoids interference from other environmental factors. In field sampling, changes in weather conditions can cause fluctuations in parameters such as light, temperature, and humidity, thus affecting the physiological state and phenotypic characteristics of leaves. The black box provides a controlled environment, allowing leaf sampling to be conducted without the influence of external factors. Whether in the morning, evening, or on a cloudy day, the black box provides stable environmental conditions, ensuring data consistency and reliability. Therefore, the use of non-destructive sampling black boxes for crop leaf phenotyping is of great significance. It helps in-depth research into the adaptability and ecological characteristics of plants, providing a scientific basis for the protection and management of ecosystems. Through its improved design and functionality, the crop leaf phenotyping black box provides important tools and support for fields such as botany, agricultural science, and environmental research. It helps researchers obtain accurate leaf information, conduct in-depth research on the mechanisms of plant growth, development, and adaptation, support crop improvement and agricultural production, and provide a powerful tool for environmental research. The introduction of this black box will promote the accuracy and efficiency of leaf analysis.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model. These improvements should also be considered within the scope of protection of the present utility model without creative effort.
