Description

Technical Field

[0001] This invention relates to the field of shape acquisition technology, specifically to a planar organ shape acquisition device and method. Background Technology

[0002] Plant variety rights are an important component of seed industry intellectual property rights. The Distinctiveness, Uniformity and Stability (DUS) test for new plant varieties is an important basis for obtaining authorization and protection of varieties, and a prerequisite for variety approval and registration. In the process of conducting DUS tests on new plant varieties, the tests are mainly conducted in accordance with published national or industry standards. The traits in the test guidelines can be roughly divided into phenotypic traits, resistance traits, and physiological and biochemical traits. Among them, phenotypic traits can be further divided into planar organ traits such as leaves, three-dimensional organ traits such as various melons and fruits, corn ears, and plant traits such as the angle between leaves and main stem.

[0003] Traditional DUS testing relies primarily on the experience of testers for grading and identification. This involves manually recording the expression status of various traits in each variety for manual grading and identification. This process is not only time-consuming and labor-intensive, but more importantly, it is highly subjective, leading to issues such as insufficient accuracy and lack of information traceability. Furthermore, existing equipment requires changing different background cloths to maintain cleanliness and improve data collection when collecting data. However, placing the background cloth directly on the tray surface can easily cause wrinkles, affecting data collection quality and reducing work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a planar organ trait collection device and method to solve the problems mentioned in the background art. Traditional DUS testing mainly relies on the experience of the tester for grading and identification. The manual recording of the expression status of each variety and trait is used for manual grading and identification. This process is not only time-consuming and labor-intensive, but more importantly, the tester's subjectivity is relatively large, resulting in insufficient accuracy and lack of information traceability. In addition, when existing equipment collects data, different background cloths need to be changed to keep them clean and increase the collection effect. However, placing the background cloth directly on the tray surface is prone to wrinkles, which affects the data collection quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a planar organ morphology collection device, comprising a collection box body, an industrial control computer box fixedly connected to its upper surface, a protective door installed on the front surface of the collection box body, a display screen fixedly installed on the side surface of the collection box body, a rotating bracket provided on the top surface of the cavity of the collection box body, a supplementary light source, an area array camera, a depth camera and a microscope camera provided at the lower end of the rotating bracket, a background cloth tray fixedly connected to the bottom surface of the cavity of the collection box body, positioning clamps installed on both sides of the background cloth tray, an electric push rod fixedly fixed to the bottom surface of the cavity of the collection box body, a linkage slider fixedly fixed at the output end of the electric push rod, support rotating arms provided on both sides of the linkage slider, two auxiliary support blocks fixedly fixed to the bottom surface of the cavity of the collection box body, support sliding columns installed on the side surfaces of the auxiliary support blocks, an auxiliary clamping block fixedly connected to one end of the support sliding column, and a linkage mechanism provided between the background cloth tray and the positioning clamping blocks.

[0006] Preferably, the collection box body and the protective door are rotatably connected, the rotating bracket is a disc-shaped design, and the rotating bracket and the collection box body are rotatably connected, and a gravity sensor is provided on the surface of the background cloth tray.

[0007] Using the above technical solution, the disc-shaped design can evenly distribute multiple components such as the supplementary light source and the area array camera, achieving a compact layout of the sensor array. The rotating connection feature allows the bracket to rotate as needed, quickly switching different sensors to the optimal acquisition angle without manual disassembly and adjustment, adapting to diverse acquisition needs, and improving the flexibility and acquisition efficiency of the equipment.

[0008] Preferably, the background cloth tray has a guide plate on its side surface, and the background cloth tray is slidably connected to the positioning clamp through the guide plate. The side surface of the positioning clamp is arc-shaped.

[0009] Using the above technical solution, the guide plate provides precise guidance for the movement of the positioning clamping blocks, ensuring that the positioning clamping blocks on both sides slide synchronously and smoothly towards each other, avoiding deviation that would cause uneven clamping of the background cloth. The sliding connection method reduces frictional resistance, making the clamping action smoother and extending the service life of the components.

[0010] Preferably, the linkage slider is rotatably connected to the support rotating arm, and the two support rotating arms are rotatably connected to the positioning clamps on both sides respectively.

[0011] By adopting the above technical solution, the power can be flexibly transmitted through the double rotation connection. When the electric push rod drives the linkage slider to move, the support arm can adaptively adjust the angle, so as to drive the positioning clamps on both sides to move closer or further away smoothly and synchronously, so as to achieve precise clamping and releasing of the background cloth and sample. The rotation connection design reduces mechanical jamming, improves the continuity and stability of the clamping action, and avoids wrinkles of the background cloth or displacement of the sample due to uneven force.

[0012] Preferably, the auxiliary support block and the supporting slide column are slidably connected, and a spring is connected between the auxiliary support block and the supporting slide column. The surface of the auxiliary clamping block is provided with an arc-shaped groove, and a guide roller is rotatably connected to the surface of the auxiliary clamping block. The two guide rollers are arranged symmetrically above and below, and the surface of the guide rollers is provided with anti-slip strips.

[0013] By adopting the above technical solution, the sliding connection combined with the elasticity of the spring enables the auxiliary clamp to have buffering and adjustment capabilities, which can adapt to background cloth or samples of different thicknesses and achieve elastic clamping. This avoids damage caused by excessive clamping while ensuring a firm clamping. The spring's reset function allows the auxiliary clamp to quickly return to its initial position after being released, improving the ease of operation.

[0014] Preferably, the linkage mechanism includes a linkage toothed plate, which is fixedly connected to the lower side surface of the background cloth tray. The positioning clamp is provided with two linkage gears inside. One end of the shaft of the linkage gear is fixedly connected to a first pulley. A tension roller is embedded in the side surface of the positioning clamp, and a second pulley is fixedly connected to the shaft surface of the tension roller.

[0015] Using the above technical solution, the linkage mechanism constructs an integrated "clamping-tensioning" transmission link through a combination design of linkage toothed plates, linkage gears, first pulleys, second pulleys, and tensioning rollers. No additional power source is required; the tensioning action is achieved solely through the movement of the positioning clamping blocks. This simplifies the mechanical structure and control logic, reduces equipment failure rates, and ensures clear division of labor among components, forming a complete power transmission closed loop. This guarantees that the background cloth clamping and tensioning actions are synchronized, improving operational efficiency.

[0016] Preferably, the upper surface of the linkage toothed plate is provided with tooth blocks, the linkage toothed plate penetrates the lower end side surface of the positioning clamping block, and the linkage toothed plate is meshed with the linkage gear through the tooth blocks.

[0017] Using the above technical solution, the linkage toothed plate is connected to the linkage gear through the meshing of the toothed block. The meshing transmission method is precise and efficient in power transmission, without slippage or free rotation. It can accurately convert the movement of the positioning clamp into the rotation of the linkage gear, ensuring the synchronicity and stability of the tensioning action. The toothed block design increases the biting force, avoids tooth slippage during transmission, improves the reliability of the mechanism operation, and ensures that the tensioning effect of the background cloth is uniform and consistent.

[0018] Preferably, the linkage gear and the positioning clamp are rotatably connected, and a transmission belt is provided between the outer surface of the first pulley and the outer surface of the second pulley.

[0019] By adopting the above technical solution, belt drive has a buffering and shock absorption function, which can absorb the impact force during the transmission process and protect components such as gears and rollers; at the same time, it can realize long-distance power transmission, adapt to the installation layout of each component, ensure that the rotation of the linkage gear is efficiently transmitted to the tensioning roller, and ensure the continuity of the tensioning action.

[0020] Preferably, the tensioning roller is rotatably connected to the positioning clamp, and the surface of the tensioning roller is provided with anti-slip rubber strips, and the tensioning roller is located between two guide rollers.

[0021] By adopting the above technical solution, the friction between the roller and the background cloth is increased, avoiding slippage during the tensioning process, ensuring that the background cloth can be effectively stretched, completely eliminating wrinkles, and ensuring the cleanliness of the background for image acquisition.

[0022] The method of using a planar organ trait acquisition device includes the following steps:

[0023] Step 1: Start the industrial control chassis and confirm through the display screen that the area scan camera, depth camera, microscope camera and other sensors and the supplementary light source are working properly. Change the background cloth according to the acquisition needs and lay it flat on the background cloth tray to ensure that the tray area is initially covered.

[0024] Step 2: Issue a clamping command through the display screen. The electric push rod drives the linkage slider to move. The support rotating arm drives the positioning clamps on both sides to slide towards each other along the guide plate to clamp and position the two ends of the background cloth. The arc-shaped positioning clamps avoid damaging the background cloth.

[0025] Step 3: When the positioning clamp moves, the linkage toothed plate on the background cloth tray meshes with the linkage gear in the positioning clamp, and drives the tension roller to rotate through the first pulley, the transmission belt and the second pulley. The tension roller is rolled with the guide roller, and the auxiliary clamp is fixed by the spring and the support slide column to completely eliminate wrinkles.

[0026] Step 4: Place the planar organ to be collected in the center of the taut background cloth. The gravity sensor on the surface of the background cloth tray detects the weight of the sample. Select the corresponding sensor through the display screen, control the rotating bracket to adjust the angle, and turn on the supplementary light source to complete the image acquisition. The acquisition process is displayed on the display screen in real time.

[0027] Step 5: After the acquisition is completed, select to export image data individually or in batches via the display screen; close the acquisition program, the electric push rod will reset and loosen the positioning clamp, remove the sample and background cloth, clean the inside of the equipment, and then close the industrial control box.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the planar organ trait acquisition equipment:

[0029] 1. This equipment addresses the pain points of traditional DUS testing, improving test objectivity and efficiency. Traditional testing relies on manual experience for grading, which is highly subjective, lacks accuracy, and makes information difficult to trace. This equipment, through multi-sensor integration and automated data acquisition, replaces manual recording and identification, significantly reducing labor costs and time consumption. At the same time, based on standardized acquisition processes and data analysis, it ensures the objectivity and traceability of test results, promoting the transformation of DUS testing from experience-based judgment to intelligent decision-making.

[0030] 2. Optimize the acquisition environment and background cloth status to ensure data acquisition quality. The equipment adopts a closed structure with a constant supplementary light source to avoid external light interference, ensuring high image clarity and consistent light source. Through the coordinated action of the linkage mechanism and clamping components, the background cloth wrinkles are automatically eliminated. The arc-shaped positioning clamp and auxiliary clamp can protect the integrity of the sample and background cloth, making the main subject of the acquired image stand out and the background clean, providing high-quality data support for subsequent morphology analysis.

[0031] 3. Adaptable to diverse needs, highly flexible and practical, equipped with integrated area array camera, micro camera, depth camera and other multi-source sensors, which can be flexibly switched through the disc-shaped rotating bracket to meet the diverse acquisition needs of planar organs of different crops, such as overall morphology, microstructure and depth information. The equipment is easy to transport and unload, simple to operate, supports batch data export, and is stable and safe to operate. It is suitable for DUS testing scenarios of various crops such as corn, rice and wheat. Attached Figure Description
