[0002] Crop phenotype characteristics are external characteristics of crops, and research on crop phenotype characteristics can obtain the relationship between crop genotype, environmental factors and crop phenotype.

[0003] In order to cultivate excellent crop varieties, it is necessary to continuously measure the changes of phenotype characteristics and physiological parameters caused by organ growth during the growth of crops. At present, the traditional artificial climate chamber only has the function of cultivating crops. The measurement of the phenotype of the crops cultivated in the artificial climate chamber currently still mainly relies on manual observation and manual measurement means for description.

[0030] Figure 1 A high-throughput photographing system for obtaining crop phenotypes according to the present invention comprises a first phenotypic acquisition unit arranged on a working plane, and a second phenotypic acquisition unit arranged above the working plane, respectively used to obtain phenotypic characteristics at a horizontal angle of view and at a top-down angle of view of the crops.

[0031] The root boxes in which the crops are grown are arranged in a straight line on the working plane in the first direction. Figure 2 Or Figure 3 As shown, they are arranged in a straight line on the working plane in the first direction. At least two sides of the root box in the first direction can be transparent to facilitate the acquisition of images of the underground part of the crops inside the root box, and the underground phenotypic characteristics of the corresponding crops can be extracted from the images. The root box can be arranged in a long strip-shaped root box holder 91 fixed by a root box fixing frame 9 on the working plane to facilitate its arrangement. The top of the root box is provided with a flash structure that exceeds the edge of the main body structure, and the root box holder is provided with a through slot corresponding to the size of the root box main body structure. When the root box is installed, the root box main body structure is nested in the through slot on the root box holder, and the flash structure abuts against the upper surface of the through slot to fix the root box. The working plane can be a seedbed capable of accommodating the root boxes and the corresponding phenotypic acquisition units. In some implementations, the root box fixing frame can be installed on the upper surface of the seedbed by fastening bolts, and the root box holder 91 is placed on the root box fixing frame 91. The root boxes are arranged in a straight line in the root box holder 91, and the side of the root box in the length direction of the root box holder 91 is transparent for shooting underground phenotypes, or the root box is opaque and can be used for cultivating and fixing crops for shooting aboveground phenotypes. The spacing between the root boxes needs to be set according to the data requirements for obtaining the top view of the crops to ensure that the crops do not overlap each other and interfere with each other during top view shooting.

[0032] In one implementation, referring to Figure 2 The first phenotypic acquisition unit comprises:

[0033] A first direction sliding guide rail 1 parallel to one side of the root box of the crops is arranged in the first direction.

[0034] A sliding plate 31 is arranged above the first direction sliding guide rail 1 and translates in the first direction along the first direction sliding guide rail 1.

[0035] a second direction sliding guide rail 32, the lower end of which is fixedly connected with the sliding plate 31, the second direction sliding guide rail 32 being perpendicular to the upper surface of the sliding plate 31 and arranged along the second direction;

[0036] a third direction sliding guide rail 33, which is connected with the second direction sliding guide rail 32 and arranged in the third direction towards the root box of the crop;

[0037] an image acquisition device 3, which is arranged at one end of the third direction sliding guide rail 33 towards the root box, and used for acquiring images of the root box and / or the crop contained in the root box at a first view angle;

[0038] a background plate 4, which is arranged at one side of the image acquisition device 3;

[0039] When the third direction sliding guide rail 33 moves along the second direction sliding guide rail 32 in the second direction, the image acquisition device 3 is driven to move synchronously, so as to adjust the height of the image acquisition device 3 relative to the root box and / or the crop contained in the root box; when the third direction sliding guide rail 33 moves relative to the second direction sliding guide rail 32 in the third direction, the image acquisition device 3 is driven to move synchronously, so as to adjust the distance of the image acquisition device 3 relative to the root box and / or the crop contained in the root box.

[0040] In a more preferable mode, the root boxes are arranged in a row along the first direction, and the image acquisition device 3 translates along the first direction sliding guide rail 1 in the first direction with the sliding plate 31, so as to sequentially acquire images of each of the root boxes and / or the crops contained in the root boxes.

[0041] In view of the fact that there is a certain difference between the phenotypic information of the two sides of the crop, two first phenotype acquisition units can be arranged, which are respectively arranged on the two sides of the root box parallel to the root box frame. Specifically, the first direction sliding guide rail 1 in each of the two first phenotype acquisition units is arranged on the two sides of the root box of the crop parallel to the first direction, and is fixedly arranged on the same working plane as the root box. The third direction sliding guide rail 33 in each of the first phenotype acquisition units and the image acquisition device 3 at the end of each third direction sliding guide rail 33 and the background plate 4 are arranged opposite to each other; the two first phenotype acquisition units respectively acquire images of different sides of each of the root boxes and / or the crops contained in the root boxes at a horizontal view angle.

[0042] In order to avoid errors and additional calculation amount caused by the opposite phenotype acquisition unit and the environment background to the extraction of the phenotype of the crop, the above-mentioned first phenotype acquisition unit is further provided with a background plate, which is used as the background when the crop is photographed. At this time, referring to Figure 2 or Figure 3The sliding plates 31 in the two first phenotype acquisition units are synchronously driven to translate in the first direction, and the image acquisition device 3 in any one of the first phenotype acquisition units always keeps facing the background plate 4 in the opposite first phenotype acquisition unit.

[0043] In order to obtain the phenotypic characteristics of the crop canopy or the whole plant, it is also necessary to take pictures of the crop from top to bottom to extract the corresponding characteristics. This perspective needs to set a second phenotype acquisition unit. In an implementation, the second phenotype acquisition unit comprises:

[0044] The top sliding guide 8 comprises two top sliding guides 8 parallel to the first direction sliding guide 1 and fixed above the root box of the crop in the first direction respectively, and the two top sliding guides 8 are arranged on the two sides of the root box of the crop respectively;

[0045] The middle sliding guide 7 is connected to the two top sliding guides 8 at both ends respectively, and the middle sliding guide 7 translates in the first direction below the top sliding guide 8;

[0046] The lower sliding guide 6 is connected to the middle sliding guide 7 at the upper end, and the second perspective image acquisition device 5 is fixed at the lower end of the lower sliding guide 6, and the lower sliding guide 6 is perpendicular to the middle sliding guide 7 and the top sliding guide 8 and moves relative to the middle sliding guide 7 in the second direction;

[0047] The second perspective image acquisition device 5 is fixed downward to the top of the root box at the lower end of the lower sliding guide 6, and the second perspective image acquisition device 5 is used to acquire the image of the root box and / or the crop contained in the root box in the second perspective.

[0048] In a more specific implementation, the first direction, the third direction and the second direction correspond to the XYZ three directions respectively. The X-Y plane forms the working plane.

[0049] Therefore, in the present application, the corresponding side view phenotype acquisition sensor group can be installed in the first phenotype acquisition unit to obtain the phenotypic data of the crop in the side view perspective. The side view phenotype acquisition sensor group is installed on the corresponding Y-direction sliding guide in the first phenotype acquisition unit. In some implementations, the side view phenotype acquisition sensor group can specifically include visible light sensors, multispectral sensors, hyperspectral sensors, thermal imaging sensors, laser radar sensors, etc. The side view phenotype acquisition sensor group can be driven by the servo motor capable of outputting X-direction driving force and the X-direction sliding guide corresponding to the servo motor to translate along the crop root box frame, thereby realizing the acquisition of the side view phenotype. In the sensor group, the focal length of each sensor can be adjusted.

[0050] The background plate is installed on the Y-direction sliding guide rail of the side view phenotype acquisition system, and the background plate is driven by the Y-direction servo motor and the Y-direction sliding guide rail. The whole high-throughput photographing system can be arranged in the climate chamber environment. The climate chamber environment is adjusted and recorded according to the set requirements to correspond to the phenotype data, and provides a data basis for the research on the action relationship between the phenotype and the environment. The climate chamber is provided with a control and analysis system, which can control two sets of side view phenotype acquisition systems to cooperate with each other: when the side view phenotype acquisition sensor group of one side of the side view phenotype acquisition system starts to acquire the phenotype data, the background plate arranged on the other side of the side view phenotype acquisition system needs to be moved to the position corresponding to the side view phenotype acquisition sensor group, and the single-color rectangular background plate is used as the background in the imaging process of the side view phenotype acquisition sensor group to acquire the side view phenotype data of the crop stem, leaf and root system. The setting of the background plate is beneficial to the processing and analysis of the phenotype data in the later stage. The climate chamber control and analysis system controls two sets of side view phenotype acquisition systems to cooperate with each other, and can complete the acquisition of the phenotype data of two sides of the crop stem, leaf and root system.

[0051] In order to ensure the image acquisition effect, the climate chamber can further be provided with a lighting system on the top of the working platform. The climate chamber control and analysis system can control the lighting system to be turned on during shooting and turned off after shooting to reduce the influence of external light on the exposed crop roots according to the use requirements.

[0052] In order to obtain the crop phenotype data under the overhead view angle, the second phenotype acquisition unit can be arranged as a top view phenotype acquisition system installed on the top of the climate chamber box. It includes XYZ three-direction servo motors, XYZ three-direction sliding guide rails, a top view phenotype acquisition sensor group, and a second view angle image acquisition device 5. The climate chamber control and analysis system can control the XYZ three-direction servo motors to drive the XYZ three-direction sliding guide rails in real time according to the acquisition requirements of the top view phenotype data of the crop stem and leaf organs, so as to drive the top view phenotype acquisition sensor group to realize the acquisition of the top view phenotype data of multiple groups of crops. The climate chamber control and analysis system can control the top view phenotype acquisition sensor group to acquire the top view phenotype data of multiple groups of crops in real time, at regular intervals and at fixed points, and then complete the storage, transmission and phenotype data analysis of the top view phenotype data of multiple groups of crops.

[0053] The overhead view type acquisition sensor group is installed at the lower end of the Z-direction sliding guide rail of the overhead view type acquisition system, which can be provided with various sensors such as visible light sensors, multispectral sensors, hyperspectral sensors, thermal imaging sensors, and laser radar sensors. The overhead view type acquisition sensor group moves synchronously with the Z-direction sliding guide rail through the driving of the Z-direction servo motor, so as to realize the shooting of crop phenotypes at different positions in the overhead view angle. The focal length of each sensor in the overhead view type acquisition sensor group is adjustable, which is convenient for automatic phenotype acquisition.

[0054] The first phenotype acquisition unit and the second phenotype acquisition unit are respectively provided with driving devices corresponding to the first direction (for example, the X-axis direction), the second direction (for example, the Y-axis direction), and the third direction (for example, the Z-axis direction). Each driving device includes three-direction servo motors and transmission assemblies connected with the driving shafts of the servo motors. The transmission assemblies drive the connection structures of the three-direction sliding guide rails to move, so as to adjust the positions of the side view type acquisition sensor group, the background plate, or the overhead view type acquisition sensor group. In a more typical implementation, the transmission assemblies can drive the image acquisition devices through the servo motors and ball screw nut pairs connected with the driving shafts of the servo motors. The image acquisition devices of each view angle are connected with the ball screw nut pairs corresponding to the directions in which the image acquisition devices are located. The servo motors drive the ball screw nut pairs to move along the first direction, the second direction, or the third direction, so as to drive the image acquisition devices corresponding to the view angles to move synchronously with the ball screw nut pairs in the directions.

[0055] In order to ensure that the two first phenotype acquisition units can move synchronously and ensure that the background plate can be arranged opposite to the camera as the background to shield the complex environment behind the crops during the collection of crop phenotypes, the image acquisition devices on the two first phenotype acquisition units in the above-mentioned implementation can be driven by the same type of servo motor and ball screw nut pair. The two image acquisition devices of the two first phenotype acquisition units in the initial state are located at the same initial position. The two servo motors are started at the same time, and the two servo motors always maintain the same steering and speed, so that the image acquisition devices and the corresponding background plate can be driven synchronously. During the collection of crop phenotypes, the image acquisition devices can correspond to the background plate, and the background plate can be used as the background of the crops, so as to simplify the steps of extracting the characteristics of crop phenotypes from the complex environment.

[0056] The climate chamber control and analysis system in the climate chamber can control the servo motor driving the sliding guide rails in the three directions of X, Y and Z according to the requirement of acquiring the side view phenotype data of the organs of the crop stems, leaves and root systems, so as to drive the corresponding phenotype acquisition sensor group to realize the acquisition of the side view phenotype data of multiple groups of crops. The climate chamber control and analysis system can control the phenotype acquisition sensor group to acquire the side view phenotype data of multiple groups of crops in real time, at regular intervals and at fixed points, store and image recognition feature extraction and other processing work of the data, and then complete the storage, transmission and phenotype data analysis of the side view phenotype data of multiple groups of crops.

[0057] In some implementations, the monitoring system can be further installed on the top of the climate chamber. Thus, the climate chamber control and analysis system can monitor the conditions in the chamber in real time according to the use requirements, and can display the conditions on the touch display screen outside the chamber in real time.

[0058] The present application can simultaneously provide crop breeding and high-throughput, high-precision and low-cost crop phenotype acquisition and analysis functions; and can simultaneously provide high-throughput, high-precision and low-cost crop phenotype acquisition and analysis functions of the aboveground organs such as stems and leaves and the underground organs such as root systems of crops under the influence of environmental factors.

[0059] The above is only an embodiment of the present application, which is described in detail and specifically, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of protection of the present application.
