Description

Technical Field

[0001] The present invention relates to the technical field of plant surface collection, and particularly relates to a portable ear phenotype collection device and method. Background Art

[0002] In the process of researching agricultural plants, it is necessary to use a camera to collect plant phenotypes. Sometimes during the detection process, the crop plants need to be planted in pots and placed on a workbench together with the pots, and then photographed with a camera. In the research of agricultural plants, the surface collection of wheat ears is also an essential one. By obtaining high-resolution images of the morphological characteristics of wheat ears (such as ear length, spikelet arrangement density, awn length, etc.), combined with machine learning algorithms for quantitative analysis, parental materials with excellent traits such as high yield and lodging resistance can be screened.

[0003] During the existing ear surface shooting and collection, the simplest and most straightforward method is to hold the camera and aim it at the wheat ear for circumferential shooting. After positioning the camera by hand, then press the shooting button on the camera handle for collection. It has a certain degree of convenience, but there are still the following problems in ear surface image collection: 1. Usually, researchers need to hold the camera and adjust the shooting at different angles and heights of the wheat ear surface. During long-term collection, it not only causes hand soreness, but also has problems of unstable shooting and poor accuracy; 2. Due to the different growth stages of wheat ears, their overall shapes and bending degrees are different, and the movements of the camera rotating around the wheat ear for shooting are also different. The technology of simply controlling the camera for automatic rotation shooting cannot meet the adaptive collection of wheat ears in different states during the collection work.

[0042] A portable ear phenotype acquisition method includes the following steps:

[0043] S1: Placement, place the whole portable ear phenotype acquisition device at the wheat ear to be acquired, and align its central area with the central drive of the wheat ear;

[0044] S2: Adjustment, press down two magnetic plates 36 so that the magnetic plates 36 are magnetically fixed on the iron ring 39, pull two groups of symmetric shooting support rods 4, and adjust the shooting rotation diameter of the camera base 6.

[0045] S3: Rotating shooting, start the control motor 221, the control motor 221 drives the passive gear two 231 to rotate through the meshing transmission of the upper half gear two 224 on the double-layer tooth shaft 222, the passive gear two 231 drives the linkage frame 25 to rotate through the inner tooth sleeve 23, the linkage frame 25 drives the limit bases 34 at both ends of the first telescopic connecting rod 32 to drive the shooting support rod 4 to rotate through the convex shaft 35, and the shooting support rod 4 drives the camera on the camera base 6 to align with the wheat ear for automatic rotating shooting work through the reciprocating lead screw 5. The two shooting support rods 4 can realize 360-degree shooting acquisition of the wheat ear surface after rotating half a week;

[0046] S4: Automatic layer change, the control motor 221 drives the passive gear one 241 to rotate through the meshing of the first half gear 223, the passive gear one 241 drives the bevel gear seat 242 to engage two small bevel gears 27 through the outer tooth sleeve 24, the small bevel gears 27 transmit the power to the reciprocating lead screw 5 through the telescopic rod 26 and the double-joint universal joint 28, and the reciprocating lead screw 5 drives the corresponding camera base 6 to realize automatic layer change when rotating in the shooting support rod 4, which not only improves the comprehensiveness and accuracy of wheat ear acquisition, but also avoids the instability and laboriousness of traditional manual operation acquisition.

[0047] The working process and principle of the present invention are as follows:

[0048] When in use, the user carries the entire device by holding the support legs 74 and the shooting rod 4. The entire device is in a retracted state, which can achieve the effect of being easy to carry. At the same time, the entire device can be adaptively photographed and collected according to the actual wheat ears. First, the control base 1 is placed as a whole on the wheat ears to be collected through the support legs 74, and the two magnetic plates 36 are pressed downward to make the magnetic plate 36 at the corresponding limit base 34 lose connection with the limit base 34, and the card strip 37 on the magnetic plate 36 loses the plug-in connection with the limit slide 33 at the corresponding position. Positioning effect, at this time, the user can directly pull the two groups of symmetrical shooting rods 4, and the shooting rods 4 as a whole drive the telescopic connecting rod 1 32 on the limiting slide 33 in the limiting base 34 to extend as a whole, and the telescopic connecting rod 1 32 extends to both sides with the axis point of the coupling rod 31 as the starting point. The user adjusts the distance between the two groups of shooting rods 4 according to the diameter required for the shooting rod 4 to rotate for shooting according to the growth of the wheat ears. During the adjustment, the force of the shooting rod 4 extending to both sides is transmitted to the support legs 74 in contact with its surface, and the two groups of support legs 74 are also adjusted to the corresponding distance.

[0049] After the rotation diameter of the shooting frame rod 4 is determined, the control motor 221 is turned on to drive the half gear 1 223 and the half gear 2 224 on the double-layer gear shaft 222 to rotate synchronously. The half gear 2 224 engages with the driven gear 2 231 first, and drives the linkage frame 25 to rotate synchronously through the inner gear sleeve 23 when driving the driven gear 2 231 to rotate. The linkage frame 25 drives the convex shaft 35 through the limiting groove provided at the bottom to drive the telescopic connecting rod 1 32 as a whole to rotate with the axis point of the coupling rod 31 as the center. The limiting bases 34 at both ends of the telescopic connecting rod 1 32 drive the two shooting frames 4 at the corresponding positions to rotate, so that the camera on the camera base 6 is aimed at the wheat ears for automatic rotation shooting. The two shooting frames 4 only need to rotate half a circle to achieve a complete shooting and collection of the wheat ears for one week, thereby achieving the effect of automatic rotation shooting and collection of the wheat ears.

[0050] After collecting the wheat ears at the same height by rotating them for a week, the second half gear 224 disengages from the second driven gear 231. At this time, the first half gear 223 meshes with and rotates the first driven gear 241. The first driven gear 241 drives the outer tooth sleeve 24 to rotate. Through the synchronous rotation of the two small bevel gears 27 meshed on the bevel gear seat 242, the two small bevel gears 27 drive the corresponding telescopic rods 26 to rotate on the limit base 34. During the rotation of the telescopic rods 26, the power is transmitted to the reciprocating lead screw 5 through the double-joint universal joint 28. When the reciprocating lead screw 5 rotates in the shooting frame rod 4, it drives the overall height adjustment of the camera base 6, thereby realizing the automatic layer change of the camera base 6. After the layer change is completed, the second half gear 224 meshes with the second driven gear 231 again, thereby realizing the effect of rotating and shooting the overall camera base 6 after the layer change, and then realizing the automatic layer change and automatic rotating shooting of the overall camera base 6. This not only improves the comprehensiveness and accuracy of the wheat ear collection, but also avoids the instability and laboriousness of the traditional manual operation for collection.

[0051] Through the setting of the telescopic rod 26 and the double-joint universal joint 28, the reciprocating lead screw 5 is driven by the power transmitted by the small bevel gear 27 while adjusting the shooting distance along with the shooting frame rod 4, realizing the automatic adaptive layer change of the overall camera base 6 while the rotation diameter is adjustable.

[0052] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.
