Description

Technical Field

[0001] This utility model relates to the field of crop measurement and identification technology, and in particular to a plant type measurement system. Background Technology

[0002] Image systems that acquire plant architecture data of crops such as corn and sorghum can be used to analyze crop phenotypic data and thereby assist in the automatic identification and analysis of various crop parameters (such as leaf number and plant height).

[0003] While it is easy to understand that a camera can be used to photograph a crop by moving it vertically back and forth on one side to obtain crop plant type data, there are no products on the market for measuring crop plant type. In the process of developing a crop-related parameter identification project, the applicant obviously needs a plant type measurement system to obtain crop plant type data. Therefore, it is necessary for the applicant to develop a plant type measurement system. Summary of the Invention

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] like Figures 1 to 3 As shown, this utility model discloses a plant type measurement system, which is used to acquire image information of crop plants and thereby analyze the crop plants. The measurement system includes: a base 13, a column 10, an imaging device 20, a drive mechanism, a distance sensor, a mobile power supply 50, and a processing controller 60.

[0034] The column 10 is vertically fixed to the middle of the base 13. The base 13 has multiple support claws for supporting the soil on the ground. The height of the column 10 needs to be higher than the height of the plant being measured, so that the measurement system can acquire image information of the entire plant.

[0035] The column 10 includes two integrally formed opposing sidewalls 11 and a bottom wall 12 between the two sidewalls 11, which together define a rectangular groove. The rear of the imaging device 20 is fixed to the front of the slider 21, and can be fixed to the front of the slider 21 using a pre-configured fixing structure. The rear of the slider 21 is located in the rectangular groove of the column 10. A sliding post 111 is provided on the inner side of the sidewall 11 of the column 10, and a sliding groove 211 is provided on the side of the slider 21 to slide in conjunction with the sliding post 111. Thus, the slider 21 can slide vertically along the column 10 without wobbling, and the imaging device 20 can reciprocate vertically along the column 10 stably.

[0036] The driving mechanism includes a stepper motor 31, a drum 32, and a pull rope 33. The stepper motor 31 is mounted on the top of the column 10 via a bracket, and the drum 32 is mounted on the output shaft of the stepper motor 31. Thus, the stepper motor 31 can drive the drum 32 to rotate. When the drum 32 is winding up the line, the pull rope 33 pulls the shooting device upward. When the drum 32 is unwinding the line, the shooting device 20 moves downward by gravity, thereby achieving vertical reciprocating motion.

[0037] The advantages of using stepper motor 31 are: on the one hand, the vertical movement speed of the shooting device 20 can be adjusted by controlling the rotation speed of stepper motor 31; on the other hand, after stepper motor 31 stops, stepper motor 31 will not rotate freely, thus keeping the shooting device 20 at the same height.

[0038] A pull-rope sensor 40 is selected as a distance sensor. The pull-rope sensor 40 is installed at the bottom of the column 10. The end of the wire of the pull-rope sensor 40 is connected to the bottom of the slider 21. Thus, when the imaging device 20 moves vertically, the slider 21 pulls the wire to measure the height of the imaging device 20, thereby obtaining the height of the imaging device 20 relative to the bottom of the plant, and thus obtaining the height of the plant segment in the image.

[0039] The shooting device 20 can be a camera or a video camera. The speed of the shooting device 20 can be calculated by the rotation speed of the stepper motor 31 and the pull rope 33. The height of the shooting device 20 can be obtained in real time by the pull rope sensor 40. By reasonably configuring the number of shooting frames of the shooting device 20, each section of the plant can be photographed and the images of each section can overlap with each other.

[0040] The processing controller 60 is used to acquire motion and position data from the stepper motor 31, the rope sensor 40, and the imaging device 20, and to acquire image data from the imaging device 20. It is also used to control the relevant parameters of the stepper motor 31, the rope sensor 40, and the imaging device 20. Thus, the processing controller 60 can obtain local image information of the plant at any corresponding height.

[0041] The power bank 50 is installed on the column 10. The power bank 50 is used to power devices such as shooting equipment 20, stepper motor 31, and rope sensor 40.
