Problems solved by technology

[0004] However, the system or platform for three-dimensional reconstruction of plant phenotypes in the prior art generally performs cumbersome processing of multiple groups of plant pictures taken by cameras, so the workload of image processing is very large, and the computing power of the platform controller requires very high
Moreover, in the process of processing, multiple different interface maps need to be obtained from each image, so to a certain extent, the speed of image processing is relatively slow, which in turn affects the speed of three-dimensional reconstruction of plants.

Embodiment 2

[0043] Corresponding to the device for acquiring plant phenotype three-dimensional reconstruction information provided in the above embodiments, the present application also provides an embodiment of a control method for the device for acquiring plant phenotype three-dimensional reconstruction information. see Figure 7 The control method of the plant phenotype three-dimensional reconstruction information acquisition device provided in this embodiment includes:

[0044] S101. Adjust the depth information sensor so that the depth information sensor is in the vertical direction of the curved upper pole, and the bottommost sensor is horizontally aligned with the upper plane of the lower pole.

[0045] Before the plant phenotype three-dimensional reconstruction information acquisition device works, the detected plant is placed on the turntable, and the height of the curved upper pole, the position of the first proximity switch and the second proximity switch, and the depth informa...

Embodiment 3

[0059] The embodiment of the present application also provides a controller, see Figure 8 , the controller 20 includes: a processor 201 , a memory 202 and a communication interface 203 .

[0060] exist Figure 8 Among them, the processor 201, the memory 202, and the communication interface 203 can be connected to each other through a bus; the bus can be divided into an address bus, a data bus, a control bus, and the like. For convenience, Figure 8 Indicated by only one thick line, but does not mean that there is only one bus or one type of bus.

[0061]The processor 201 usually controls the overall function of the controller 20, such as the startup of the controller, and the control of the first stepping motor and the second stepping motor after the controller is started, so as to realize the work of the depth information sensor and the plant rotating platform , and obtain multiple collected plant cross-sectional images and canopy-level images. In addition, the processor...

Abstract

The invention discloses a plant phenotype three-dimensional reconstruction information obtaining device and a control method thereof. A plant rotation platform is fixedly arranged on a worktable. A bended movable rod is arrangedat one side of the worktable. A bended end corresponds to a plane of the plant rotation platform in parallel. A depth information sensor is set at theside, corresponding toa table surface of the worktable, of the movable rod. The depth information sensor is movably connected with the movable rod. A movable range is from the bended end to a connected end of the movablerod and the worktable. A first stepping motor is arrangedon the movable rod. A second stepping motor is arranged on the plant rotation platform. The depth information sensor can move along the movablerod under the action of the first stepping motor, thereby carrying out image collection on a cross section and a canopy surface of a plant placed on the plant rotation platform. The plant rotation platform can carry out 360-degree rotation. A plurality of 360-degree images of the cross section and the canopy surface of the plant can be collected for plant phenotype three-dimensional reconstruction in a later period. Complex processing does not need to be carried out on each image.

Description

technical field [0001] The present application relates to the technical field of three-dimensional reconstruction of plants, in particular to a plant phenotype three-dimensional reconstruction information acquisition device and a control method thereof. Background technique [0002] At present, plant phenomics serves as a bridge between mitigation functional genomics and plant breeding research, and plant phenotype-related traits are closely related to plant genome and plant field management. The acquisition of plant phenotypic characteristic parameters has always been the first step in plant phenomics research, and it is also a key step. Traditionally, the acquisition of plant phenotype information mostly relies on manual measurement by personnel, which is time-consuming and labor-intensive. For different types of plants, personnel measurement is accidental, and the reliability of measurement data is low. [0003] With the maturity of technology, researchers at home and ab...
