Description

Technical Field

[0001] This invention relates to the field of plant phenotyping technology, specifically to an adjustable-size plant rotation scanning mechanism. Background Technology

[0002] With the continuous deepening of modern agriculture and plant science research, the demand for high-precision scanning and reconstruction of plant morphology and structure is becoming increasingly urgent.

[0003] Existing solutions typically involve rigidly mounting the camera on a fixed bracket, relying solely on the rotation of the entire plant to acquire data. While this approach is structurally simple, it cannot dynamically adjust the relative position between the camera and the target based on the actual size of the plant. This results in small plants having an insufficient image size and resolution, while larger plants exhibit localized blurring because some areas exceed the depth of field. Although some adjustable scanning devices on the market attempt to move the camera position using telescopic arms or sliding rails, the adjustment process often relies on complex transmission mechanisms or manual intervention, leading to slow response, poor repeatability, and difficulty in achieving multi-angle, multi-scale collaborative optimization. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable-size plant rotation scanning mechanism to solve the technical problems in the prior art.

[0005] This invention provides an adjustable-size plant rotation scanning mechanism, including a mounting frame, multiple drive components, and multiple image acquisition components. The mounting frame has an arc-shaped structure. The multiple drive components and the multiple image acquisition components correspond one-to-one. Each drive component includes a drive member and a telescopic member. The drive member is mounted on the mounting frame and connected to the telescopic member to drive the telescopic member to move closer to or away from the center of the mounting frame. The image acquisition components are mounted on the telescopic member.

[0006] Optionally, the telescopic component includes a crankshaft arm, a first connecting rod, a second connecting rod, and a limiting rod. One end of the crankshaft arm is hinged to the drive component, the other end of the crankshaft arm is hinged to one end of the first connecting rod, the other end of the first connecting rod is hinged to one end of the second connecting rod, the other end of the second connecting rod is connected to the image acquisition assembly, the limiting rod is disposed on the mounting bracket and extends toward the center of the mounting bracket, and the second connecting rod is slidably disposed on the limiting rod.

[0007] Optionally, the limiting rod is provided with a mounting portion extending along the thickness direction of the limiting rod, and the mounting portion is provided with a limiting through hole extending along the length direction of the limiting rod, and the second connecting rod passes through the limiting through hole.

[0008] Optionally, the plant rotation scanning mechanism further includes a mounting bracket having opposing first and second surfaces, the second connecting rod being hinged to the first surface, and the second surface having mounting holes for connection with the image acquisition component.

[0009] Optionally, the mounting bracket is a prismatic structure with a channel extending along its length, the two ends of the channel being open, the mounting hole being a strip-shaped hole communicating with the channel, and the number of mounting holes including at least two, which are evenly distributed along the length of the mounting bracket.

[0010] Optionally, the arc-shaped structure includes a notch for plants to enter and exit.

[0011] Optionally, the number of the driving components and the image acquisition components each includes at least five, and the at least five driving components and the image acquisition components are distributed at intervals along the mounting frame.

[0012] Optionally, the plant rotation scanning mechanism further includes a power source and a fixing frame. The fixing frame is arc-shaped and fits against the mounting frame. The power source is used to drive the fixing frame to rotate.

[0013] Optionally, the driving component is a drive motor, and the mounting bracket has a first mounting surface and a second mounting surface that are disposed opposite to each other, with the drive motor embedded between the first mounting surface and the second mounting surface.

[0014] Optionally, the drive component is located on one side of the first mounting surface, and the second mounting surface is provided with a wiring groove for mounting signal lines, the wiring groove being an arc shape adapted to the shape of the mounting bracket.

[0015] Compared to existing technologies, under the action of the driving component, the telescopic component can move closer to or further away from the center of the mounting frame, allowing the image acquisition component to also move closer to or further away from the center of the mounting frame, which is the placement position of the plant. This allows the image acquisition component to move closer to or further away from the plant. When the plant is large, the driving component moves the telescopic component and the image acquisition component away from the plant, maintaining a suitable distance between them to ensure an appropriate plant imaging ratio and high resolution. When the plant is small, the driving component moves the telescopic component and the image acquisition component closer to the plant, ensuring an appropriate plant imaging ratio and high resolution. In some cases, such as when the plant is small overall but has a large outward extension area, some of the telescopic component and the image acquisition component can be moved closer to the plant, while others can be moved further away. This allows for dynamic adjustment of the positions of the telescopic component and the image acquisition component according to the specific shape of the plant. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, the present invention provides an adjustable-size plant rotation scanning mechanism, which includes a mounting frame 20, multiple drive components 30 and multiple image acquisition components (not shown in the figure). The multiple drive components 30 and the multiple image acquisition components correspond one-to-one, that is, the number of drive components 30 and the number of image acquisition components are the same. The image acquisition components can be devices with image acquisition functions such as cameras or webcams, so as to complete the scanning of plant morphology and structure.

[0020] The mounting frame 20 has an arc-shaped structure so that it can surround the plant, thereby allowing the plant to be imaged from multiple angles around it. The drive assembly 30 includes a drive member 31 and a telescopic member. The drive member 31 is mounted on the mounting frame 20 and is connected to the telescopic member to drive the telescopic member to move closer to or away from the center of the mounting frame 20. The image acquisition assembly is mounted on the telescopic member.

[0021] In the above technical solution, under the action of the driving component 31, the telescopic component can move closer to or further away from the center of the mounting frame 20, so that the image acquisition component can also move closer to or further away from the center of the mounting frame 20. The center of the mounting frame 20 is the position of the plant to be scanned. This allows the image acquisition component to move closer to or further away from the plant. When the plant is large, under the action of the driving component 31, the telescopic component and the image acquisition component are moved away from the plant, so that a suitable distance can be maintained between the image acquisition component and the plant, ensuring that the plant imaging ratio is appropriate and the resolution is high. When the plant is small, under the action of the driving component 31, the telescopic component and the image acquisition component are moved closer to the plant, ensuring that the plant imaging ratio is appropriate and the resolution is high. In situations where the plant as a whole is small, but a certain area of ​​its outward extension is large, some of the telescopic components and image acquisition components can be placed closer to the plant, while others can be placed further away. This allows for dynamic adjustment of the positions of the telescopic components and image acquisition components according to the plant's specific shape. As a result, this plant rotation scanning mechanism is applicable to plants of different sizes and can adjust the position of the image acquisition components according to the plant's specific shape, resulting in high image clarity. It effectively avoids the problem of small plants appearing too small or large plants being out of focus in certain areas, significantly improving image quality and providing reliable technical support for high-throughput, high-precision plant phenotypic analysis.

[0022] like Figure 1 and Figure 3 As shown, the telescopic component includes a crankshaft arm 32, a first connecting rod 33, a second connecting rod 34, and a limiting rod 35. One end of the crankshaft arm 32 is hinged to the drive member 31, and the other end of the crankshaft arm 32 is hinged to one end of the first connecting rod 33. The other end of the first connecting rod 33 is hinged to one end of the second connecting rod 34, and the other end of the second connecting rod 34 is connected to the image acquisition component. The limiting rod 35 is mounted on the mounting bracket 20 and extends toward the center of the mounting bracket 20. The second connecting rod 34 is slidably mounted on the limiting rod 35. The drive member 31 can drive the crankshaft arm 32 to rotate. The connecting rod 33 is hinged to the crankshaft arm 32 and the second connecting rod 34 respectively. The second connecting rod 34 is restricted in direction by the limiting rod 35, so that when the driving member 31 drives the crankshaft arm 32 to rotate, the second connecting rod 34 will move forward or backward in the direction pointing to the center of the mounting frame 20. This can change the distance between the image acquisition component and the center of the mounting frame 20, so as to adjust the distance between the image acquisition component and the plant according to the different sizes and dimensions of the plant or the local extension of the plant, thereby making the image acquisition component and the plant have a suitable image acquisition distance to improve the imaging quality.

[0023] Specifically, the limiting rod 35 is provided with a mounting part 36 extending along the thickness direction of the limiting rod 35, and the mounting part 36 is provided with a limiting through hole 361 extending along the length direction of the limiting rod 35. The second connecting rod 34 passes through the limiting through hole 361. The shape of the second connecting rod 34 is adapted to the limiting through hole 361, that is, the second connecting rod 34 and the limiting through hole 361 are in a clearance fit relationship, so that the second connecting rod 34 abuts against the inner wall of the limiting through hole 361. When the driving member 31 drives the crankshaft arm 32 to rotate, the second connecting rod 34 can always move forward or backward along the axial direction of the limiting through hole 361, thereby ensuring that the second connecting rod 34 performs reciprocating linear motion and avoiding the problem of poor imaging angle caused by the left and right swing of the second connecting rod 34.

[0024] like Figure 2 and Figure 3 As shown, the plant rotation scanning mechanism also includes a mounting bracket 40, which has a first surface 41 and a second surface 42 facing each other. A second connecting rod 34 is hinged to the first surface 41. The second surface 42 is provided with a mounting hole 43 for connecting to an image acquisition component. By hinged the second connecting rod 34 to the first surface 41 of the mounting bracket 40, the mounting bracket 40 can be angled relative to the second connecting rod 34 to selectively adjust the angle of the image acquisition component located on the mounting bracket according to different plant shapes, ensuring that the image acquisition component is in a suitable image acquisition position. The first surface 41 and the second surface 42 can be flat, so that the image acquisition component, after being mounted on the second surface 42, can face the plant directly.

[0025] like Figure 3 As shown, the mounting bracket 40 has a prismatic structure and a channel 44 extending along its length. The channel 44 is open at both ends, and the mounting hole 43 is a strip-shaped hole communicating with the channel 44. The image acquisition component can be mounted in the mounting hole 43 using bolts and nuts. The channel 44 provides working space for the bolts and nuts. The strip-shaped mounting hole 43 allows the image acquisition component to be adjusted in position along its length. There are at least two mounting holes 43, evenly distributed along the length of the mounting bracket 40. Specifically, there can be two or four mounting holes 43, which can be symmetrically distributed about the center of the mounting bracket 40. As an example, the image acquisition component can be provided with a connecting hole, through which bolts pass, and into the mounting hole 43, with the tail of the bolt extending into the channel 44. The bolts are then tightened with a nut to complete the connection between the image acquisition component and the mounting bracket 40.

[0026] like Figure 1As shown, the arc-shaped structure includes a notch 23, which allows the plant to enter and exit. When scanning the plant 50, the plant can be placed upright first. (It should be noted that...) Figure 1 The plants shown are placed horizontally; however, during actual scanning, plants are generally placed upright. Figure 1 The plant rotation scanning mechanism and the plant as a whole are rotated 90 degrees clockwise to the actual scanning position. The notch 23 is aligned with the head of the plant. Then the height of the plant rotation scanning mechanism is gradually reduced so that the plant 50 gradually enters the interior of the arc-shaped structure through the notch 23. When the image acquisition component can cover most of the plant, the height of the plant rotation scanning mechanism can be reduced. This is the appropriate image acquisition position.

[0027] like Figure 1 As shown, the number of driving components 30 and image acquisition components includes at least five. The at least five driving components 30 and image acquisition components are distributed at intervals along the mounting frame 20. The number of driving components 30 and image acquisition components can be determined according to the size of the mounting frame 20, such as five, six or seven. By evenly setting the driving components 30 and image acquisition components on the mounting frame 20, the plant can be scanned from all directions to improve the imaging quality.

[0028] like Figure 1 As shown, the plant rotation scanning mechanism also includes a power source and a mounting frame 10. The mounting frame 10 is arc-shaped and fits into the mounting frame 20. The mounting frame 10 can be fixed to the side of the mounting frame 20 or to the bottom of the mounting frame 20. By setting the shapes of the two to be consistent, it is easy to connect the mounting frame 10 and the mounting frame 20 together and make the connection more secure. The power source is used to drive the mounting frame 10 to rotate. The power source can be a motor. The motor can drive the mounting frame 10 to rotate through a gear transmission mechanism, thereby enabling 360-degree surround shooting of the plant.

[0029] like Figure 2 As shown, the drive component 31 is a drive motor. The mounting bracket 20 has a first mounting surface 21 and a second mounting surface 22 that are arranged opposite to each other. The drive motor is embedded between the first mounting surface 21 and the second mounting surface 22. Specifically, a through hole 24 can be opened along the thickness direction of the mounting bracket 20. The through hole 24 passes through the first mounting surface 21 and the second mounting surface 22 respectively, so that the drive motor can be installed in the through hole 24 between the first mounting surface 21 and the second mounting surface 22. The drive motor can be fixed in the through hole 24 by a flange structure. Setting the drive motor in the through hole 24 can avoid the problem of the drive motor being easily damaged due to protruding from the mounting bracket 20, and play a role in protecting the drive motor.

[0030] like Figure 2As shown, the drive assembly 30 is located on the side of the first mounting surface 21, and the second mounting surface 22 is provided with a wiring groove 25 for mounting signal lines. The signal lines can be the power and control lines of the drive motor, or the power and signal lines of the camera, etc. The wiring groove 25 is an arc shape that matches the shape of the mounting bracket 20. By arranging the power lines of the drive motor, control lines, camera power lines, and signal lines in the wiring groove 25 of the second mounting surface 22, the pulling of the power lines of the drive motor, control lines, camera power lines, and signal lines during the movement of the plant rotation scanning mechanism can be avoided, thereby ensuring the safety and accuracy of the scanning process. At the same time, the entire plant rotation scanning mechanism is also neater.
