Description

Technical Field

[0001] The present invention relates to the technical field related to plant phenotypic information collection, and in particular to a plant phenotypic information collection device and collection method. Background Art

[0002] Plant phenotype refers to all the physical, physiological, and biochemical characteristics and traits that reflect the structure and composition of plants, as well as the process and results of plant growth and development. Accurately acquiring plant phenotypic information is an important foundation for agricultural scientific research. By collecting images of plants from multiple angles and combining them with artificial intelligence algorithms, it is possible to reconstruct the three-dimensional structure of plants and extract phenotypic information.

[0003] Publication No. CN110375158B discloses a plant phenotypic information collection device and collection method, which belongs to the field of plant phenotypic information collection equipment. In the plant phenotypic information collection device of the present invention, a collection platform is provided with a blackout curtain and a driving member capable of driving the blackout curtain cloth to rise and fall on the base. When the collection platform is used to collect plant information, the curtain cloth can cover the plants to be collected after being lowered and form a dark box environment, so that the collection platform can adapt to the collection of plant phenotypic information in different external environments, thereby being able to collect phenotypic information of plants in different growth periods or external environments, and the collection efficiency is high. The collection method of the present invention has high collection efficiency and high accuracy of the collected information.

[0004] This patent collects data by adjusting the height of the gimbal, but in actual use, the angles of leaves and branches are not the same. Data collection may be affected by the angle, resulting in overlapping leaves or branches in the recognition results, which will cause errors in the final recognition results. At the same time, when using blackout curtains to create a dark box environment to improve recognition accuracy during shooting, the blackout curtains need to be adjusted multiple times, which is too cumbersome. The use of fill lights may have a certain impact on subsequent growth, thereby affecting the growth result records of the plants. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plant phenotypic information collection device and collection method to solve the problems existing in the above-mentioned background technology.

[0007] When in use, the rotation of the roller drives the connecting pulley fixed on the inner side to rotate, and the connecting pulley drives the driven pulley on the top to rotate through the belt arranged on it, and the driven pulley drives the connecting rod fixedly connected to the side to rotate. On the one hand, the connecting rod drives the intercepting plate fixed to it to rotate, and on the other hand, it drives the driven gear engaged with the bottom to rotate. The driven gear drives the collecting device to rotate. When the intercepting plate rotates clockwise, the collecting device arranged at the bottom rotates counterclockwise, which can reduce the influence of external light on the shooting results when the collecting device is collecting data, and can also collect plant data from multiple angles, thereby improving data accuracy.

[0008] Furthermore, a connecting side plate is rotatably connected to the outer side surface of the driven pulley, and the outer side surface of the driven gear is also rotatably connected to the connecting side plate. A support block is fixedly connected to the side surface of the connecting side plate, and a slide rail is provided at the bottom of the connecting side plate. The roller and the slide rail are movably connected, and the support block and the slide rail are movably connected.

[0009] Furthermore, the acquisition device includes a acquisition camera, the top of the acquisition camera is fixedly connected to a connecting seat, the side of the connecting seat is rotatably connected to a driving wheel, and the driving wheel is movably connected to a limiting plate.

[0010] Furthermore, a bottom plate is fixedly connected to the bottom of the slide rail, and a central portion of the bottom plate is a planting area.

[0012] Furthermore, a filter is fixedly connected to the side surface of the baffle, and the filter is an interference filter that reflects red light, and is used to absorb and reflect the red light portion of the light directly incident on the filter, allowing light of other colors to pass through.

[0013] Furthermore, the inner side surface of the filter is movably connected to a left movable plate and a right movable plate, and the side surfaces of the left movable plate and the right movable plate are fixedly connected to connecting blocks.

[0014] Furthermore, a fixed block is fixedly connected to the intercepting side plate, the connecting block is arranged at the fixed block and movably connected to the fixed block, and a No. 2 through hole is opened on the left movable plate and the right movable plate, and the aperture of the No. 2 through hole is the same as that of the No. 1 through hole.

[0015] During the collection process, the collection camera can also move horizontally on the limit plate through the connecting seat to perform multi-position image recognition, which can improve the speed and accuracy of plant phenotypic information collection.

[0016] A collection method of a plant phenotype information collection device, the method comprising:

[0017] S1: During the acquisition process, the roller is driven by a motor to rotate on the slide rail. When the acquisition camera on the acquisition device is at the shooting angle at the two end positions, the interception plate is also at the two end positions. The left movable plate on the interception plate moves downward under the action of gravity, and the left movable plate is clamped by the coordinated movement of the fixed block and the connecting block, so that the No. 2 through hole opened on the left movable plate and the No. 1 through hole on the baffle plate are misaligned. The left movable plate blocks the light from the No. 1 through hole, and the edge of the right movable plate is stuck with the baffle plate, so that the No. 1 through hole and the No. 2 through hole on the right movable plate will not be misaligned, and the light can be transmitted from the right movable plate. The initial shooting position of the acquisition camera is below the left movable plate, and the light transmitted from the right movable plate can also fill the light for the acquisition device, thereby enhancing the image recognition capability of the acquisition camera;

[0018] S2: When the interception plate moves to the center of the bottom plate along with the roller, the left movable plate and the right movable plate move to the sides under the influence of gravity, and the No. 2 through hole on the left movable plate and the right movable plate is misaligned with the No. 1 through hole on the baffle plate, thereby blocking the light from above from entering the collection camera below the interception plate. At this time, the interception plate is at a higher position, and the light on both sides of the interception plate is relatively sufficient. The additional fill light may affect the image recognition ability of the collection camera;

[0019] S3: When the acquisition camera on the acquisition device is at a shooting angle at the right end position, the intercepting plate is also at the right end position at this time, and the right movable plate on the intercepting plate moves downward under the action of gravity, and the right movable plate is stuck through the coordinated movement of the fixed block and the connecting block, so that the No. 2 through hole opened on the right movable plate and the No. 1 through hole on the baffle are misaligned, and the right movable plate will block the light from the No. 1 through hole, while the edge of the left movable plate is stuck with the baffle, resulting in no misalignment between the No. 1 through hole and the No. 2 through hole on the left movable plate, and light can pass through the left movable plate. At this time, the shooting angle of the acquisition camera is below the right movable plate, and the light passing through the left movable plate can also fill in the light for the acquisition device.
