Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plant phenotype information collection, and in particular to a plant phenotype collection device. Background Art
[0002] Plant phenotype is determined or influenced by genes and environmental factors, and reflects all physical, physiological, and biochemical characteristics and traits of plant structure and composition, plant growth and development process and results. In the field of biology and genetic breeding, especially crop breeding, phenotype refers to the external characteristics of organisms such as shape, structure, size, color, etc. determined by genotype and environment.
[0003] In recent years, plant genomes have developed rapidly. Phenotypic monitoring can not only guide indoor germplasm screening in the early stage of breeding, but also evaluate the field performance of varieties in the later promotion and planting. When obtaining plant phenotypic data, sometimes it is necessary not only to shoot from above the plant, to collect the morphological and structural phenotypic information such as the crown width, projected area, number of canopy leaves, canopy compactness, and organ phenotypic information such as leaves and fruits from a bird's-eye view angle, but also to shoot from the side of the plant, to collect morphological and structural phenotypic information such as plant height, stem thickness, plant width, and organ phenotypic information such as flowers, leaves, and stems from a side view angle. If plant images are collected from only one angle, the types of phenotypic information obtained are single. If you want to obtain rich and complete phenotypic information, you often install a camera (imaging sensor) at the bird's-eye view angle and the side view angle, but this will inevitably increase costs and make the collection and processing process more cumbersome.
[0004] In addition, currently, only one type of camera is usually installed in an imaging darkroom, such as a visible light camera, a fluorescent camera, an infrared camera, a lidar, a hyperspectral camera, etc. Different types of cameras can obtain different phenotypic data (information). Visible light cameras are used to record images of plants at different stages of growth and calculate the geometric dimensions of plants through pixels; infrared cameras are used to record the difference in water content at different stages of plant growth; fluorescent cameras are used to record the changes in chemical reactions of plants after being stressed by fluorescence; hyperspectral cameras are used to measure plant differences or the distribution of different elements in plants; and lidar is used to measure the distribution of plant space or the space occupied. At present, when using different types of cameras to obtain different plant phenotypic data, multiple imaging darkrooms are usually arranged and the camera types in each imaging darkroom are different, but this will inevitably increase the space and cost occupied by the plant phenotypic acquisition device. This deficiency is particularly prominent in laboratories with limited space. Summary of the invention
[0005] In order to solve the above problems, the present application provides a plant phenotype collection device with ingenious design and simple structure. The present application improves the integration of the collection device and the diversity of photography by centrally arranging at least one type of camera on a rotating component, and arranging the rotating component on a mobile frame. In the present application, the same camera can take pictures of both the top and the side of the plant. The technical solutions adopted by the present application are as follows:
[0006] A plant phenotype collection device, characterized by comprising:
[0007] A camera, the camera is used to capture plant phenotypic data; a rotating component, the camera is arranged on the rotating component, the axial length direction of the rotating component is consistent with the X-axis, and the rotating component can carry the camera to rotate around the axis of the rotating component to adjust the shooting direction of the camera; a mobile frame, the rotating component is installed on the mobile frame, and the mobile frame can carry the rotating component to reciprocate along the Z-axis direction and the Y-axis direction; an imaging darkroom, the camera, the rotating component and the mobile frame are all arranged in the imaging darkroom.
[0008] By setting the camera on a rotating component and setting the rotating component on a movable frame, the camera can rotate with the rotation of the rotating component, and the camera can be moved to the top of the plant, the side of the plant, and the upper side of the plant by moving the movable frame, so that the same camera can be used not only to shoot the top of the plant, but also to shoot the side of the plant. In other words, through the movable (including rotating) design of the camera, the same camera can be used to shoot the plant from multiple directions and angles, without the need to separately deploy a camera at each shooting position of the plant, thus saving the number of cameras deployed and greatly reducing the cost.
[0009] In some embodiments, there are multiple cameras of different types, and the multiple cameras are spaced apart around the axis of the rotating component; the types of the cameras are switched by rotating the multiple cameras through the rotating component.
[0010] By arranging a plurality of different types of cameras on a rotating assembly, the rotation of the rotating assembly is used to make a certain type of camera reach a shooting position, and when the camera type needs to be switched, it can be achieved by controlling the rotation of the rotating assembly, so that the plant phenotype collection device can obtain different types of phenotypic data, thereby improving the applicability of the plant phenotype collection device. At the same time, a plurality of different types of cameras are simultaneously arranged on the same rotating assembly, which greatly saves the occupied space and production and transportation costs of the plant phenotype collection device.
[0011] In some embodiments, the plant phenotype collection device further includes a fill light, which is mounted on the rotating component. The fill light can rotate synchronously with the camera around the axis of the rotating component, and the fill light is used to provide fill light for the plant.
[0012] By setting the fill light on the rotating component and making the fill light and the camera rotate synchronously, that is, the movement path (motion trajectory) of the fill light and the camera are consistent, the fill light can provide fill light synchronously no matter which shooting position the camera is in. There is no need to separately arrange a fill light adapted to this shooting position at each shooting position of the plant, which saves the number of fill lights and the space occupied, and reduces the cost.
[0013] In some embodiments, the mobile frame includes a Z-axis moving component, a Y-axis moving component and an X-axis beam, the Z-axis moving component is installed on the moving part of the Y-axis moving component, the X-axis beam is installed on the moving part of the Z-axis moving component, and the rotating component is installed on the X-axis beam.
[0014] By installing the Z-axis moving component on the moving part of the Y-axis moving component and the X-axis beam on the moving part of the Z-axis moving component, this arrangement can save the number of Z-axis moving components or Y-axis moving components used while ensuring the stability of the moving frame.
[0015] In some embodiments, the rotating assembly is a rotary drive, and the camera is mounted on a turntable of the rotary drive.
[0016] In some embodiments, the rotary drive is provided with a through hole, the through hole is coaxially arranged with the axis of the rotary drive, and the rotary drive is inserted through the through hole and is sleeved outside the X-axis crossbeam.
[0017] By putting the rotary drive outside the X-axis beam, the overall height of the rotary drive after being installed on the X-axis beam can be reduced, thus saving vertical space.
[0018] In some embodiments, the rotary drive is a toothed rotary drive.
[0019] Generally speaking, compared with the worm gear type slewing drive, the gear type slewing drive has a simpler structure, smaller weight and volume, and is less likely to block the camera and fill light.
[0020] In some embodiments, the Z-axis moving assembly and the Y-axis moving assembly are both linear guides, and the moving parts of the Z-axis moving assembly and the moving parts of the Y-axis moving assembly are both sliders on the linear guides.
[0021] In some embodiments, the plant phenotype collection device further comprises a conveyor line, wherein the conveyor line is used to transport the plants to be photographed, and the conveyor line passes through the imaging darkroom.
[0022] The plant phenotype collection device provided in the present application has at least one of the following beneficial effects:

A plant phenotype collection device provided by the present application, by setting a camera on a rotating component, and setting the rotating component on a movable frame, so that the camera can rotate with the rotation of the rotating component, and the camera can be moved to the top of the plant, the side of the plant, and the upper and lower sides of the plant by moving the movable frame, so that the same camera can be used to shoot not only the top of the plant, but also the side of the plant. That is to say, through the movable (including rotating) design of the camera, the same camera can shoot the plant from multiple directions and angles, without the need to separately arrange a camera at each shooting position of the plant, thereby saving the number of cameras to be arranged and greatly reducing the cost.
[0024] 2. The present application provides a plant phenotype collection device, which arranges multiple different types of cameras on a rotating component, utilizes the rotation of the rotating component to make one type of camera reach the shooting position, and when the camera type needs to be switched, it can be achieved by controlling the rotation of the rotating component, which enables the plant phenotype collection device to obtain different types of phenotypic data, thereby improving the applicability of the plant phenotype collection device. At the same time, multiple different types of cameras are simultaneously arranged on the same rotating component, which greatly saves the space occupied by the plant phenotype collection device and the production and transportation costs.
[0025] 3. A plant phenotype collection device provided in the present application sets a fill light on a rotating component, and the fill light and the camera can rotate synchronously, that is, the movement path (motion trajectory) of the fill light and the camera are consistent. In this way, no matter which shooting position the camera is in, the fill light can provide fill light synchronously. There is no need to separately arrange a fill light adapted to this shooting position at each shooting position of the plant, which saves the number of fill lights and the space occupied, and reduces the cost.

[0043] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.
[0044] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".
[0045] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.
[0046] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0047] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0048] refer to Figure 1-Figure 10 The present application provides a plant phenotype collection device, characterized in that it includes: a camera 1, a rotating component 2, a mobile frame and an imaging darkroom 3, the camera 1 is used to shoot plant phenotypic data; the camera 1 is arranged on the rotating component 2, the axial length direction of the rotating component 2 is consistent with the X-axis, the rotating component 2 can carry the camera 1 to rotate around the axis of the rotating component 2 to adjust the shooting direction of the camera 1; the rotating component 2 is installed on the mobile frame, and the mobile frame can carry the rotating component 2 to reciprocate along the Z-axis direction and the Y-axis direction; the camera 1, the rotating component 2 and the mobile frame are all arranged in the imaging darkroom 3, and the imaging darkroom 3 provides a shooting space for the plants entering the imaging darkroom 3.
[0049] It should be noted that the X-axis, Y-axis, and Z-axis mentioned in the present application represent three orthogonal directions, which are only used to enable technical personnel to clearly understand the positional relationship, orientation relationship or layout direction of each component or assembly. That is to say, in other embodiments, the X-axis, Y-axis, and Z-axis can be interchangeable.
[0050] It can be understood that by setting the camera 1 on the rotating component 2, and setting the rotating component 2 on the mobile frame, the camera 1 can rotate with the rotation of the rotating component 2, and the camera 1 can be moved to the top of the plant, the side of the plant, and the upper side of the plant by moving the mobile frame, so that the same camera 1 can be used not only to shoot the top of the plant, but also to shoot the side of the plant. That is to say, through the movable (including rotation) design of the camera 1, the same camera 1 can shoot the plant from multiple directions and angles, and there is no need to separately arrange the camera 1 at each shooting position of the plant, which saves the number of cameras 1 and greatly reduces the cost.
[0051] Specifically, the number of cameras 1 provided on the rotating assembly 2 may be one or multiple cameras 1 of different types. Different types of cameras 1 can obtain different phenotypic data, for example, a visible light camera is used to record images of plants at different growth stages and calculate the geometric dimensions of plants through pixels; an infrared camera is used to record the difference in water content at different growth stages of plants; a fluorescent camera is used to record the changes in chemical reactions of plants after being stressed by fluorescence; a hyperspectral camera is used to measure plant differences or the distribution of different elements in plants; and a laser radar is used to measure the spatial distribution of plants or the spatial position occupied by them.
[0052] When there is only one camera 1, the type of camera 1 can be one of visible light camera, fluorescent camera, infrared camera, laser radar, hyperspectral camera, etc. When there are multiple cameras 1 of different types, the type of camera 1 can be two, three or more types of visible light camera, fluorescent camera, infrared camera, laser radar, hyperspectral camera, etc.
[0053] It is understandable that when a plurality of cameras 1 of different types are arranged on the rotating assembly 2, the plurality of cameras 1 are spaced apart around the axis of the rotating assembly 2, and the type of the camera 1 is switched by the rotation of the rotating assembly 2 carrying the plurality of cameras 1. It is worth noting that by arranging a plurality of cameras 1 of different types on the rotating assembly 2, and utilizing the rotation of the rotating assembly 2 to enable a certain type of camera 1 to reach the shooting position, when the type of camera 1 needs to be switched, it can be achieved by controlling the rotation of the rotating assembly 2, which enables the plant phenotype collection device to obtain different types of phenotypic data, thereby improving the applicability of the plant phenotype collection device. At the same time, a plurality of cameras 1 of different types are arranged on the same rotating assembly 2 at the same time, which greatly saves the occupied space and production and transportation costs of the plant phenotype collection device.
[0054] refer to Figure 1-Figure 4 , Figure 6-Figure 9 In one embodiment, the plant phenotype collection device also includes a fill light 4, which is installed on the rotating component 2. The fill light 4 can rotate synchronously with the camera 1 around the axis of the rotating component 2, and the fill light 4 is used to provide fill light for the plant.
[0055] It is worth noting that by setting the fill light 4 on the rotating component 2, and the fill light 4 and the camera 1 can rotate synchronously, that is, the movement path (motion trajectory) of the fill light 4 and the camera 1 are consistent, so no matter which shooting position the camera 1 is in, the fill light 4 can provide fill light synchronously, and there is no need to separately arrange a fill light 4 adapted to this shooting position at each shooting position of the plant, which saves the number of fill lights 4 and the space occupied, and reduces the cost.
[0056] refer to Figure 1 , Figure 2 , Figure 7-10 In one embodiment, the mobile frame includes a Z-axis moving component 5, a Y-axis moving component 6 and an X-axis beam 7, the Z-axis moving component 5 is installed on the moving part of the Y-axis moving component 6, the X-axis beam 7 is installed on the moving part of the Z-axis moving component 5, and the rotating component 2 is installed on the X-axis beam 7.
[0057] Specifically, the Z-axis moving assembly 5 and the Y-axis moving assembly 6 can be linear guides or ball screws. When the Z-axis moving assembly 5 and the Y-axis moving assembly 6 are both linear guides, the moving parts of the Z-axis moving assembly 5 and the moving parts of the Y-axis moving assembly 6 are both sliders on the linear guides. When the Z-axis moving assembly 5 and the Y-axis moving assembly 6 are both ball screws, the moving parts of the Z-axis moving assembly 5 and the moving parts of the Y-axis moving assembly 6 are both screw nuts on the ball screws.
[0058] In this embodiment, reference Fig.11 , the layout of the components of the mobile frame belongs to Fig.11 In other embodiments, the layout of the components of the mobile frame can be Fig.11Type B or Type C. In Type A, the Y-axis moving assembly 6 is fixed on the frame in the imaging darkroom 3, and the Y-axis moving assembly 6 should be installed as high as possible in the imaging darkroom 3, so that the center of gravity of the whole formed by the rotating assembly 2, the Z-axis moving assembly 5, the X-axis beam 7 and other components is as low as possible from the center of gravity of the Y-axis moving assembly 6, thereby ensuring the stability and displacement accuracy of the mobile frame during operation and reducing the risk of camera 1 shaking. In Type B, the Z-axis moving assembly 5 is fixed on the frame in the imaging darkroom 3, the Y-axis moving assembly 6 is installed on the moving part of the Z-axis moving assembly 5, the X-axis beam 7 is installed on the moving part of the Y-axis moving assembly 6, and the rotating assembly 2 is installed on the X-axis beam 7. Compared with Type A, the layout of Type B has a greater risk of shaking of the Y-axis moving assembly 6 because the Y-axis moving assembly 6 is cantilevered, and the stability of the entire mobile frame is poor during operation and the displacement accuracy is greatly reduced. In type C, compared with type B, the number of Z-axis moving components 5 is increased. By increasing the number of Z-axis moving components 5, more support points are provided for the Y-axis moving components 6 to improve the stability and displacement accuracy of the moving frame during operation, but this will greatly increase the cost.
[0059] It can be understood that in this embodiment, by installing the Z-axis moving component 5 on the moving part of the Y-axis moving component 6, and the X-axis beam 7 on the moving part of the Z-axis moving component 5, this arrangement can save the number of Z-axis moving components 5 or Y-axis moving components 6 used while ensuring the stability of the moving frame.
[0060] refer to Figure 1-Figure 5 , Figure 7-10 In one embodiment, the rotating component 2 is rotationally driven, and the camera 1 is mounted on a turntable 8 of the rotational drive.
[0061] Specifically, the rotary drive can be a gear rotary drive or a worm gear rotary drive, preferably a gear rotary drive. Generally speaking, compared with the worm gear rotary drive, the gear rotary drive has a drive motor 12 whose axis (rotating shaft) is parallel to the axis (rotating shaft) of the rotary drive, and the setting of the drive motor 12 is not easy to block the camera 1 and the fill light 4; while the axis (rotating shaft) of the drive motor of the worm gear rotary drive is perpendicular to the axis (rotating shaft) of the rotary drive, and the setting of the drive motor is easy to block the camera 1 and the fill light 4, which increases the difficulty of selecting the worm gear rotary drive. In addition, compared with the worm gear rotary drive, the gear rotary drive has a simple structure and is smaller in weight and volume. It can be understood that both the gear rotary drive and the worm gear rotary drive are prior art and will not be repeated here.
[0062] Specifically, refer to Figure 3-Figure 6The camera 1 is fixed on the rotary drive turntable 8 through an L-shaped mounting plate 13. The fill light 4 is fixed on the L-shaped mounting plate 13 through a universal ball joint structure 14, and the irradiation direction of the fill light 4 can be easily adjusted by using the universal ball joint structure 14.
[0063] refer to Figure 1-Figure 5 , Figure 7-10 In one embodiment, the rotary drive is provided with a through hole 9, which is coaxially arranged with the axis of the rotary drive, and the rotary drive is sleeved outside the X-axis beam 7 through the through hole 9. By sleeved the rotary drive outside the X-axis beam 7, the overall height of the rotary drive after being installed on the X-axis beam 7 can be made smaller, saving vertical space. In other embodiments, the entire rotary drive can also be arranged as a whole on one side of the X-axis beam 7. It can be understood that the rotary drive with the through hole 9 is a prior art and will not be described in detail here.
[0064] refer to Fig. 9 , Fig.10 In one embodiment, the plant phenotype collection device further includes a conveyor line 10 , which is used to transport the plants to be photographed, and the conveyor line 10 passes through the imaging darkroom 3 .
[0065] Specifically, the imaging darkroom 3 provides a shooting space for the plants entering the imaging darkroom 3. The imaging darkroom 3 is provided with two electric doors 11, which are respectively arranged on the path of the conveyor line 10 entering and exiting the imaging darkroom 3. By controlling the switch of the electric doors 11, the plants can enter or exit the imaging darkroom 3. When it is necessary to shoot the plants in the imaging darkroom 3, the two electric doors 11 are in a closed state.
[0066] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
