Description

Technical Field

[0001] This utility model relates to the field of aerial surveying technology, and in particular, to a mechanism for rapid deployment of aerial surveying image control points. Background Technology

[0002] Image control points are the foundation of photogrammetric control densification and mapping. The quality of the selection of field image control point targets and the accuracy of the indication points directly affect the accuracy of the measurement results. The main method of aerial surveying is to use UAVs for measurement, which has the characteristics of being mobile and flexible, efficient and fast, precise and accurate, low operating cost, wide applicability and short production cycle. When conducting aerial surveys of photovoltaic sites, topographic maps, power lines and other similar projects, it is necessary to set up control points, and the area is relatively large.

[0003] The existing method of setting up control points is usually to spray markings on the ground. However, this method is not accurate enough. Manual spraying introduces errors and is affected by factors such as terrain. Poor terrain increases the workload of setting up, and the effect of setting up is generally not good. For aerial surveys covering large areas, the inability to complete the setting up quickly will greatly reduce the overall operational efficiency.

[0004] Therefore, there is an urgent need to provide a mechanism for the rapid deployment of aerial survey control points to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rapid deployment mechanism for aerial survey image control points to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid deployment mechanism for aerial survey image control points includes a first main board 1, a second main board 2 rotatably connected to one end of the first main board 1, a first sub-board 3 disposed on the top of the first main board 1, and a second sub-board 4 disposed on the bottom of the second main board 2.

[0008] A sub-board rotation mechanism 7 is provided at one side connection point of the first main board 1 and the first sub-board 3. A sub-board rotation mechanism 7 is also provided at one side connection point of the second main board 2 and the second sub-board 4. The sub-board rotation mechanism 7 includes a limiting fixing sleeve 701, a rotating connecting sleeve 702 and a connecting rotating shaft 703. A pair of limiting fixing sleeves 701 are provided on the first main board 1 and the second main board 2. The rotating connecting sleeves 702 are provided on the first sub-board 3 and the second sub-board 4. The connecting rotating shaft 703 is rotatably connected between the two limiting fixing sleeves 701 and the rotating connecting sleeves 702, so that the first main board 1 and the first sub-board 3 are rotatably connected, and the second main board 2 and the second sub-board 4 are rotatably connected.

[0009] A fixing mechanism 8 is provided on the other side of the first main board 1, the first sub-board 3, the second main board 2, and the second sub-board 4. The fixing mechanism 8 includes a fixing shaft 801 respectively disposed on the first main board 1, the first sub-board 3, the second main board 2, and the second sub-board 4. A rotating ring 802 is rotatably connected to each fixing shaft 801. A pin 803 is fixedly connected to one side of each rotating ring 802. An arc-shaped locking plate 804 is engaged at one end of the pin 803. The arc-shaped locking plate 804 is fixedly connected to the side wall of the first main board 1, the first sub-board 3, the second main board 2, and the second sub-board 4 respectively.

[0010] Furthermore, the connection end between the first motherboard 1 and the second motherboard 2 is provided with two fixed bushings 6, and a rotating shaft seat 5 is rotatably connected between the two fixed bushings 6.

[0011] The above technical solution enables a rotating connection between the first motherboard and the second motherboard.

[0012] Furthermore, the upper surface of the first main board 1 is provided with a groove that matches the first sub-board 3, and the lower surface of the second main board 2 is provided with a groove that matches the second sub-board 4.

[0013] The above technical solution ensures that the first and second sub-boards can be rotated on the first and second main boards and stored in the grooves, and can be completely stored together after the first and second main boards are rotated and folded.

[0014] Furthermore, the sub-plate rotation mechanism 7 is located at the center of the side.

[0015] Furthermore, the two fixing mechanisms on the first main board 1 and the second main board 2 are arranged symmetrically vertically, and the two fixing mechanisms on the first sub-board 1 and the second sub-board 2 are also arranged symmetrically vertically.

[0016] Furthermore, the end of the pin 803 furthest from the rotating ring 802 is tapered.

[0017] The above technical solution ensures that the entire device can be fixed by inserting multiple pins into the ground.

[0018] Compared with existing technologies, the rapid deployment mechanism for aerial survey image control points of this utility model has the following advantages:

[0019] Beneficial effects:

[0020] 1. This utility model completes aerial surveying by unfolding a first main board, a second main board, a first sub-board, and a second sub-board, and by using the image control points presented by the coating on the unfolded boards. The unfolded structure greatly improves the deployment efficiency, and the device can be recycled and used multiple times.

[0021] 2. This utility model allows the entire device to be stored by unfolding and folding the first main board, the second main board, the first sub-board, and the second sub-board, which occupies little space and is easy to carry. At the same time, the entire device can be quickly fixed by multiple fixed mechanisms. Attached Figure Description

[0030] Example

[0031] like Figure 1 , Figure 5As shown, this utility model proposes a rapid deployment mechanism for aerial survey image control points, including a first main board 1. A second main board 2 is rotatably connected to one end of the first main board 1. Specifically, two fixed bushings 6 are provided at the connection end between the first main board 1 and the second main board 2, and a rotating bearing 5 is rotatably connected between the two fixed bushings 6. The rotatable connection between the first main board and the second main board is achieved through the rotating bearing 5 and the fixed bushings. A first sub-board 3 is provided on the top of the first main board 1, and a second sub-board 4 is provided on the bottom of the second main board 2.

[0032] like Figures 3-6 As shown, the upper surface of the first main board 1 has a groove adapted to the first sub-board 3, and the lower surface of the second main board 2 has a groove adapted to the second sub-board 4. The first and second sub-boards can be rotated on the first and second main boards and stored in the grooves. After the first and second main boards are rotated and folded, they can be completely stored together. A sub-board rotation mechanism 7 is provided at one side connection between the first main board 1 and the first sub-board 3, and a sub-board rotation mechanism 7 is also provided at one side connection between the second main board 2 and the second sub-board 4. The sub-board rotation mechanism 7 is located in the center of the side. The sub-board rotation mechanism 7 includes a limiting fixing sleeve 701, a rotating connecting sleeve 702, and a connecting rotating shaft 703. A pair of limiting fixing sleeves 701 are provided on both the first main board 1 and the second main board 2. The rotating connecting sleeves 702 are provided on the first sub-board 3 and the second sub-board 4. The connecting rotating shaft 703 is rotatably connected between the two limiting fixing sleeves 701 and the rotating connecting sleeves 702, so that the first main board 1 and the first sub-board 3 are rotatably connected, and the second main board 2 and the second sub-board 4 are rotatably connected.

[0033] like Figure 1 , Figure 2 As shown, a fixing mechanism 8 is provided on the other side of the first main board 1, the first sub-board 3, the second main board 2, and the second sub-board 4. The fixing mechanism 8 includes a fixing shaft 801 respectively disposed on the first main board 1, the first sub-board 3, the second main board 2, and the second sub-board 4. The two fixing mechanisms disposed on the first main board 1 and the second main board 2 are arranged symmetrically vertically, and the two fixing mechanisms disposed on the first sub-board 1 and the second sub-board 2 are also arranged symmetrically vertically. A rotating ring 802 is rotatably connected to each fixing shaft 801. A pin 803 is fixedly connected to one side of each rotating ring 802. One end of the pin 803 is engaged with an arc-shaped locking plate 804. The arc-shaped locking plates 804 are fixedly connected to the side walls of the first main board 1, the first sub-board 3, the second main board 2, and the second sub-board 4 respectively. The end of the pin 803 away from the rotating ring 802 is tapered, ensuring that the entire device can be fixed by inserting multiple pins into the ground.

[0034] In use, this invention requires repainting the upward-facing surfaces of the first main board 1, second main board 2, first sub-board 3, and second sub-board 4 with marking pigment beforehand to ensure the accuracy of aerial surveying. Then, the first main board 1 and second main board 2 are unfolded by rotating the bearing seat 5 and two fixed bushings 6. The first sub-board 3 and second sub-board 4 can be unfolded by rotating the two limiting fixed sleeves 701, rotating connecting sleeves 702, and connecting rotating shaft 703 in the sub-board rotating mechanism 7. Then, the pins 803 on the first main board 1, second main board 2, first sub-board 3, and second sub-board 4 are removed from the arc-shaped clamping plate 804. As the rotating ring 802 rotates on the fixed rotating shaft 801, the pins 803 can be inserted into the ground to fix the entire device. When the UAV is performing terrain-following flight, aerial surveying can be completed through multiple deployed image control points.
