Description

Technical Field

[0001] The utility model relates to the technical field of camera brackets, and specifically, to a bracket mechanism for image acquisition and a target detection device. Background Art

[0002] In the management of crops such as wolfberries, grapes, and morel mushrooms that are planted in large areas and concentratedly, in order to achieve purposes such as precise individualized crop management such as fixed-point spraying and fixed-point picking, generally, based on methods such as image recognition, the detection or spatial positioning of relevant targets is realized.

[0003] Currently, the general applicability of existing image acquisition mechanisms is poor, and it is difficult to stably acquire original images in various crop planting environments.

[0004] Currently, when technicians photograph planted crops, most of them fix the camera through a bracket. However, most of the commonly used brackets are fixed brackets, which mainly include three telescopic support feet and a support platform for placing the camera; since most planted crops grow in farmland, and the land around the farmland is soft and rough, when technicians place the bracket, it is easy to cause the bracket and the support platform to tilt. A large tilt is easy for technicians to observe, but a small tilt is difficult for technicians to observe with the naked eye, ultimately resulting in poor image effects obtained by the camera. Summary of the Utility Model

[0005] The utility model provides a bracket mechanism for image acquisition and a target detection device, which can overcome certain or some defects of the prior art.

[0006] According to a bracket mechanism for image acquisition of the utility model, it includes: a bracket main body, the bracket main body includes a mounting seat and 3 support feet for supporting the mounting seat; the mounting seat includes a lower support column hinged to the support feet and an upper support column for placing the camera; an adjustment assembly is provided between the lower support column and the upper support column, and the adjustment assembly is used to push the upper support column to adjust the inclination of the upper support column.

[0007] With the present utility model, when technicians go to the field for shooting, first, by rotating the mounting block, the rotation of the mounting block drives the rotation of the second threaded column. The rotation of the second threaded column causes the second threaded column to extend into the connecting groove, thereby lifting the mounting ring. The upward movement of the mounting ring pushes the first hinge rod to move, and the first hinge rod pushes the support feet apart, thus facilitating the technicians to open the support feet. After the support feet are opened, insert the lower ends of the support feet into the soil and adjust the overall inclination of the support frame body. Then, the technicians rotate different rotating disks, causing the first threaded rod to axially move along the guiding hole, thereby pushing the upper support column to incline. When the upper support column inclines, observe the bubble in the level calibrator at the support table. Determine whether the upper support column is inclined based on the position of the bubble. When the bubble is at the center of the level calibrator, the upper support column is balanced. At this time, the technicians place the camera on the support table. Thus, it is ensured that the camera is in a horizontal state, enabling the camera to remain horizontal when shooting planted crops, ensuring that the captured images are not skewed and can accurately reflect the true state of the planted crops. And accurate and clear images can be obtained.

[0008] Preferably, a spherical rotating block is provided below the upper support column, and a connecting rod is provided between the rotating block and the upper support column. A spherical limiting groove for the rotating block to extend into is provided at the lower support column, and a limiting hole for the connecting rod to pass through is provided at the limiting groove. The diameter of the limiting hole is larger than the diameter of the connecting rod. A plurality of guiding holes are also provided at the lower support column, which are circumferentially distributed along the limiting hole and arranged along the length direction of the lower support column. A lifting member that axially moves along the guiding hole is provided in the guiding hole. The lifting member includes a first threaded rod disposed in the guiding hole. One end of the first threaded rod is provided with a rotating disk located between the lower support column and the upper support column, and an internal thread that cooperates with the first threaded rod is provided on the inner side wall of the guiding hole.

[0009] With the present utility model, the technicians adjust the inclination of the upper support column by adjusting the length of different first threaded rods extending out of the guiding holes. When the first threaded rod rises to push the upper support column, the rotating block below the upper support column rotates in the limiting groove, thereby preventing the upper support column from detaching from the lower support column.

[0010] Preferably, the upper support column includes a connecting column connected to the connecting rod. One end of the connecting column away from the connecting rod is provided with a support table, and a level calibrator is provided on the side wall of the support table.

[0011] With the present utility model, when the technicians adjust the inclination of the upper support column, by observing the position of the bubble in the level calibrator, determine whether the upper support column is horizontal, thus facilitating the technicians to know whether the upper support column is horizontal.

[0012] Preferably, a pushing mechanism for pushing three support feet apart is provided below the lower support column; the pushing mechanism includes a second threaded column, and a connection groove for the second threaded column to extend into is provided at the lower end of the lower support column, and an internal thread that is threadedly engaged with the second threaded column is provided on the inner side wall of the connection groove; an installation block is provided at the lower end of the second threaded column, and an annular groove is formed by the side wall of the installation block being recessed inward in the circumferential direction; an installation ring is provided at the annular groove, and a through hole for the installation block to pass through is provided at the installation ring; a plurality of first hinge rods distributed circumferentially are provided on the side wall of the installation ring, and both ends of the first hinge rod are respectively hinged to the installation ring and the support foot.

[0013] With the present utility model, the technician rotates the installation block, causing the second threaded column to rotate. At this time, the second threaded column moves upward or downward. When the second threaded column moves upward, the second threaded column pulls the installation ring upward, thereby causing the installation ring to push the three sleeves apart, so that the three sleeves are separated, thus opening the support feet; when the second threaded column moves downward, the second threaded column pulls the installation ring downward, causing the installation ring to pull the three sleeves, so that the three sleeves are combined, thus storing the support feet, which is convenient for the technician to carry.

[0014] Preferably, a handle is provided at the lower end of the installation block.

[0015] With the present utility model, the technician rotates the handle, thereby driving the installation block to rotate, which is convenient for the technician to rotate the second threaded column.

[0016] Preferably, the support foot includes a sleeve, a support rod with a rectangular cross-section is provided inside the sleeve, a plurality of first fixing holes are provided at intervals along the length direction of the support rod, and two second fixing holes corresponding to the first fixing holes are provided at the sleeve; a limiting pin passing through the first fixing hole and the second fixing hole is provided at the sleeve; one end of the sleeve is provided with a second hinge rod hinged to the lower support column.

[0017] With the present utility model, the technician can pull the support rod to extend the support rod out of the sleeve, and then pass the limiting pin through the first fixing hole and the second fixing hole on the support rod and the sleeve, thereby fixing the support rod and the sleeve, which is convenient for the technician to extend the length of the support foot to adapt to the height of different planted crops.

[0018] Preferably, a fixing foot with a conical shape is provided at the end of the support rod away from the sleeve.

[0029] As Figure 1-7 shown, in this embodiment, a bracket mechanism for image acquisition is provided, including a bracket body 100. The bracket body 100 includes a mounting base 110 and three support feet 120 for supporting the mounting base 110. The mounting base 110 includes a lower support column 401 hinged to the support feet 120 and an upper support column 400 for placing the camera. An adjustment assembly is provided between the lower support column 401 and the upper support column 400, and the adjustment assembly is used to push the upper support column 400 to adjust the inclination of the upper support column 400.

[0030] In this embodiment, when technicians go to the field to take pictures, they first rotate the mounting block 510. The rotation of the mounting block 510 drives the rotation of the second threaded column 570. The rotation of the second threaded column 570 causes the second threaded column 570 to extend into the connection groove 330, so that the mounting ring 540 moves upward. The upward movement of the mounting ring 540 pushes the first hinge rod 550 to move, and the first hinge rod 550 pushes the support feet 120 apart, thus facilitating the technicians to open the support feet 120. After the support feet 120 are opened, the lower ends of the support feet 120 are inserted into the soil, and the inclination of the entire bracket body 100 is adjusted. Then, the technicians rotate different rotating disks 440, so that the first threaded rod 450 axially moves along the guide hole 310, thereby pushing the upper support column 400 to incline. When the upper support column 400 inclines, observe the water bubble in the level calibrator 402 at the support platform 410. Judge whether the upper support column 400 is inclined according to the position of the water bubble. When the water bubble is located at the center of the level calibrator 402, the upper support column 400 is balanced. At this time, the technicians place the camera on the support platform 410. Thus, it is ensured that the camera is in a horizontal state, so that when the camera takes pictures of the planted crops, the camera remains horizontal to ensure that the captured images are not skewed and can accurately reflect the true state of the planted crops. And accurate and clear images can be obtained.

[0031] In this embodiment, a spherical rotating block 480 is provided below the upper support column 400. A connecting rod 490 is provided between the rotating block 480 and the upper support column 400. A spherical limiting groove 320 for the rotating block 480 to extend into is provided at the lower support column 401. A limiting hole 470 for the connecting rod 490 to pass through is provided at the limiting groove 320. The diameter of the limiting hole 470 is larger than the diameter of the connecting rod 490. A plurality of guide holes 310 are also provided at the lower support column 401, which are circumferentially distributed along the limiting hole 470 and arranged along the length direction of the lower support column 401. A lifting member that axially moves along the guide hole 310 is provided in the guide hole 310. The lifting member includes a first threaded rod 450 provided in the guide hole 310. One end of the first threaded rod 450 is provided with a rotating disk 440 located between the lower support column 401 and the upper support column 400. An internal thread that cooperates with the first threaded rod 450 is provided on the inner side wall of the guide hole 310.

[0032] In this embodiment, the technicians adjust the inclination of the upper support column 400 by adjusting the length of different first threaded rods 450 extending out of the guide holes 310. When the first threaded rod 450 rises to push the upper support column 400, the rotating block 480 below the upper support column 400 rotates in the limiting groove 320, thereby preventing the upper support column 400 from detaching from the lower support column 401.

[0033] In this embodiment, the upper support column 400 includes a connecting column 420 connected to the connecting rod 490. At one end of the connecting column 420 away from the connecting rod 490, there is a support platform 410, and a horizontal calibrator 402 is provided on the side wall of the support platform 410.

[0034] Through this embodiment, when adjusting the inclination of the upper support column 400, technicians can determine whether the upper support column 400 is horizontal by observing the position of the bubble in the horizontal calibrator 402, thus facilitating the technicians to know whether the upper support column 400 is horizontal.

[0035] In this embodiment, a pushing mechanism 130 for pushing three support feet 120 apart is provided below the lower support column 401; the pushing mechanism 130 includes a second threaded column 570. A connecting groove 330 for the second threaded column 570 to extend into is provided at the lower end of the lower support column 401, and internal threads that are threadedly engaged with the second threaded column 570 are provided on the inner side wall of the connecting groove 330; an installation block 510 is provided at the lower end of the second threaded column 570, and an annular groove 520 is formed by the side wall of the installation block 510 being recessed inward along the circumferential direction; an installation ring 540 is provided at the annular groove 520, and a through hole 560 for the installation block 510 to pass through is provided at the installation ring 540; a plurality of first hinge rods 550 distributed along the circumferential direction are provided on the side wall of the installation ring 540, and both ends of the first hinge rod 550 are respectively hinged to the installation ring 540 and the support foot 120.

[0036] Through this embodiment, technicians rotate the installation block 510 to make the second threaded column 570 rotate. At this time, the second threaded column 570 moves upward or downward. When the second threaded column 570 moves upward, the second threaded column 570 pulls the installation ring 540 upward, so that the installation ring 540 pushes three sleeves 620, separating the three sleeves 620, thereby opening the support feet 120; when the second threaded column 570 moves downward, the second threaded column 570 pulls the installation ring 540 downward, causing the installation ring 540 to pull the three sleeves 620, merging the three sleeves 620, thereby storing the support feet 120, which is convenient for technicians to carry.

[0037] In this embodiment, a handle 530 is provided at the lower end of the installation block 510.

[0038] Through this embodiment, technicians rotate the handle 530, thereby driving the installation block 510 to rotate, thus facilitating the technicians to rotate the second threaded column 570.

[0039] In this embodiment, the support leg 120 includes a sleeve 620. Inside the sleeve 620, there is a support rod 670 with a rectangular cross-section. At the support rod 670, there are a plurality of first fixing holes 650 arranged at intervals along the length direction of the support rod 670. At the sleeve 620, there are two second fixing holes 630 corresponding to the first fixing holes 650; at the sleeve 620, there is a limit pin 660 passing through the first fixing hole 650 and the second fixing hole 630; one end of the sleeve 620 is provided with a second hinge rod 610 hinged to the lower support column 401.

[0040] Through this embodiment, the technician can pull the support rod 670 to extend the support rod 670 out of the sleeve 620, and then pass the limit pin 660 through the first fixing hole 650 and the second fixing hole 630 on the support rod 670 and the sleeve 620, so as to fix the support rod 670 and the sleeve 620, thereby facilitating the technician to extend the length of the support leg 120 to adapt to the heights of different planted crops.

[0041] In this embodiment, a fixing foot 640 with a conical shape is provided at one end of the support rod 670 away from the sleeve 620.

[0042] Through this embodiment, the conical fixing foot 640 facilitates the technician to insert the support rod 670 into the soil to fix the support rod 670.

[0043] Above the support platform 410, there is also a tray 710. The tray 710 is used for the technician to place a computer or other supplies used during shooting. The tray can adopt an existing quick-release buckle structure to achieve quick installation with the support platform 410, providing an installation space for terminal devices such as a binocular camera and / or a computer, with stable force and being beneficial for practical use.
