Description

Technical Field

[0001] The present invention relates to the field of monitoring camera equipment, and more specifically, to a crop growth monitoring device and a measuring method thereof. Background Art

[0002] Crop growth is a key indicator for measuring crop growth status and predicting yield, which covers crop height, leaf area, biomass, color and other aspects. In modern agricultural production mode, farmers use high-definition cameras to remotely monitor the growth of crops, and rely on long-term experience to roughly judge the growth status of crops by the appearance characteristics of crop images transmitted back, such as leaf color and plant density.

[0003] In order to enable high-definition camera devices to monitor crops planted in large areas from different directions and increase the monitoring area, Eagle Eye heavy-duty high-definition camera devices are generally used to monitor crops. Existing Eagle Eye heavy-duty high-definition camera devices are mostly composed of a layer of several circumferentially arranged fixed wide-angle cameras and a ball camera structure. The several circumferentially arranged fixed wide-angle cameras are used to achieve circumferential monitoring and increase the monitoring area. The ball camera can be controlled by a remote control terminal to achieve switching monitoring in different directions. However, in actual use, the inventor found that although the several circumferentially arranged fixed wide-angle cameras can form an effective annular monitoring surface, their monitoring range can only be changed by a remote control terminal in the form of zoom, which is not very convenient for further control and change of the upper and lower circumferential monitoring surfaces, and is relatively inconvenient to use. Therefore, we propose a crop growth monitoring device and a measurement method thereof to solve the above-mentioned problems. Summary of the invention

[0026] Example 2

[0027] In view of the above embodiment 1, for further description, refer to Figure 3-Figure 7 : 2. Wide-angle camera pitch angle adjustment: 1. Select the wide-angle camera to be adjusted In addition to controlling the zoom and rotation direction of the ball camera 17, the remote control terminal can also control the wide-angle cameras 5, which are not less than 4 in the annular housing 1. When the pitch angle of a wide-angle camera 5 needs to be adjusted, first select the corresponding wide-angle camera 5 on the remote control terminal.

[0028] 2. Servo motor moves The servo motor 12 is controlled to start, and the servo motor 12 drives the motor base plate 13 to rotate, and the motor base plate 13 then drives the servo motor 2 14 to rotate, and the servo motor 2 14 drives the convex head plug-in 15 to rotate, so that the convex head plug-in 15 rotates to the position of the opening plug-in 9 corresponding to the selected wide-angle camera 5. At this time, the servo motor 12 stops starting, and the convex part of the convex head plug-in 15 is plugged into the opening part of the corresponding opening plug-in 9.

[0029] 3. Servo motor 2 drives the wide-angle camera to pitch The servo motor 2 14 is started, driving the convex plug-in 15 to rotate, and the convex plug-in 15 drives the opening plug-in 9, the rotating shaft 7 and the gear 8 to rotate. The gear 8 rotates and engages with the inner wall tooth edge of the annular portion 1001 of the driving member 10, driving the driving member 10 to move up and down as a whole. Due to the sliding connection between the column portion 1002 and the sleeve 401 and the cooperation between the rack portion 1003 and the sliding hole 201, the driving member 10 can only reciprocate up and down, which improves the stability of the structure. When the driving member 10 moves up and down, the rack portion 1003 moves up and down, and the tooth opening on one side of the rack portion 1003 is engaged with the tooth opening of the concave tooth groove 501 on the outer wall of the corresponding wide-angle camera 5, driving the corresponding wide-angle camera 5 to do up and down pitching movements, thereby achieving the effect of adjusting the area surface monitored by the wide-angle camera 5 upward and downward.

[0030] 4. Complete the adjustment and prepare for the next camera When the pitch angle adjustment of the wide-angle camera 5 is completed, the servo motor 2 14 stops starting, and then the servo motor 1 12 starts again, so that the convex plug-in 15 is re-plugged into another opening plug-in 9, and the next wide-angle camera 5 is ready to be pitched. And so on, until the pitch angle adjustment process of all wide-angle cameras 5 is satisfied, and the mechanical structure is realized to independently adjust the angles of several wide-angle cameras 5. During the entire adjustment process, since the servo motor has the characteristics of high rotation precision, the driving structure of the servo motor 1 12 and the servo motor 2 14 can make the rotation of the driving shaft more precise, avoid interference when the convex plug-in 15 is plugged into the opening plug-in 9, and ensure that the adjustment process is accurate and reliable.

[0031] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
