[0026] Embodiment 1:

[0027] Please refer to Figure 1-Figure 3 As shown, this embodiment provides an aerial swing-scanning camera device with a correction function, which is arranged on an aircraft, preferably below the aircraft. In this embodiment, the aircraft can be a drone, a helicopter, a passenger plane, etc.

[0028] The aerial swing-sweep photography device comprises: a main frame 1, a swing-sweep assembly 3, a correction assembly 4 and a camera 2. The swing-sweep assembly 3 is arranged on the main frame 1. The main frame 1 is used to connect with the aircraft and can also protect the swing-sweep assembly 3, the correction assembly 4 and the camera 2. The swing-sweep assembly 3 is arranged on the main frame 1, preferably arranged inside the main frame 1, so that the main frame 1 can protect the swing-sweep assembly 3. The correction assembly 4 is arranged on the swing-sweep assembly 3 and can swing with a first straight line as an axis under the drive of the swing-sweep assembly 3. The camera 2 is arranged on the correction assembly 4 and can swing with a second straight line as an axis under the drive of the correction assembly 4, and the first straight line is perpendicular to the second straight line. At the same time, in order to make the shooting effect better, the first straight line is parallel to the flight direction of the aircraft (the second straight line is perpendicular to the movement direction of the aircraft at this time), and the angle between the optical axis direction of the camera 2 (which can be understood as the shooting direction) and the second straight line is greater than 0, that is, the two are not parallel.

[0029] The aerial swing-sweep camera device provided in this embodiment is loaded under the aircraft when in use, and the aircraft is controlled to fly above the location to be photographed. Specifically, the aerial swing-sweep camera device can be suspended under the aircraft, or a cabin can be set under the aircraft, and the aerial swing-sweep camera device can be installed in the cabin, and an opening that enables the swing camera device to shoot normally is provided under the cabin when shooting. When shooting, the swing-sweep component 3 drives the deviation correction component 4 and the camera 2 to swing with the first straight line as the axis, and controls the camera 2 to continuously shoot during the swinging process (actually interval shooting, for example, shooting once every 0.1 seconds, and the specific shooting interval can be adjusted according to actual needs), so that the camera 2 can shoot at multiple angles. The aerial swing-sweep camera device provided in this embodiment only needs one camera 2 to complete multi-angle aerial shooting, thereby reducing costs and reducing the load pressure of the aircraft.

[0030] At the same time, since the aircraft is in motion when the aerial swing-sweep camera device is shooting, even if the shooting interval of the camera 2 is very small, due to the movement of the aircraft, the photos taken by the camera 2 in one swing cycle (swing cycle of the swing-sweep component 3) cannot be guaranteed to be on the same straight line, which will cause errors when the computer generates three-dimensional data based on the photos, affecting the accuracy. In this embodiment, by setting the correction component 4, the camera 2 can swing with the first straight line as the axis and the second straight line as the axis at the same time to adapt to the movement of the aircraft, so that the photos taken by the camera 2 in one swing cycle (swing cycle of the swing-sweep component 3) can be on the same straight line, avoiding the decrease in the accuracy of the three-dimensional data due to shooting errors.

[0031] In the specific implementation, in order to ensure the stable connection between the aerial swing camera device and the aircraft, the main frame 1 is preferably made of metal material. At the same time, in order to reduce the overall weight as much as possible, the main frame 1 can be made of lightweight metal materials such as aluminum alloy.

[0032] For further information, please refer to Figure 2 As shown, in this embodiment, the main frame 1 has a storage space, and the swing-sweep assembly 3, the deflection correction assembly 4 and the camera 2 are arranged in the storage space. The swing-sweep assembly 3, the deflection correction assembly 4 and the camera 2 are arranged in the storage space of the main frame 1, so that the main frame 1 can cover the swing-sweep assembly 3, the deflection correction assembly 4 and the camera 2, so that the main frame 1 can provide more comprehensive protection for the swing-sweep assembly 3, the deflection correction assembly 4 and the camera 2.

[0033] For further information, please refer to Figure 3 As shown, in this embodiment, the sweeping assembly 3 includes a swinging connection frame 31 and a swinging motor 32, the swinging connection frame 31 is connected to the main frame 1, the correction assembly 4 is movably arranged on the swinging connection frame 31, and the swinging motor 32 is connected to the correction assembly 4, and is used to drive the correction assembly 4 to drive the camera 2 to swing, and when the correction assembly 4 swings, the first straight line coincides with the axis of the rotating shaft of the swinging motor 32. The correction assembly 4 and the swinging motor 32 are connected to the main frame 1 through the swinging connection frame 31, wherein the swinging connection frame 31 and the main frame 1 can be directly connected or indirectly connected through other devices or components. The swinging motor 32 is arranged on the swinging connection frame 31, and is connected to the correction assembly 4 through transmission parts such as bearings, so that the swinging motor 32 can drive the correction assembly 4 to swing. At the same time, in order to ensure the accuracy of control, the swinging motor 32 preferably uses a stepping motor or a servo motor.

[0034] For further information, please refer to Figure 3 As shown, in this embodiment, the swing connection frame 31 has a first swing connection part and a second swing connection part which are arranged oppositely and at intervals, the correction component 4 is movably arranged between the first swing connection part and the second swing connection part, and the swing motor 32 is arranged on the first swing connection part and connected to the correction component 4. Specifically, the two opposite sides of the correction component 4 are respectively rotatably connected to the first swing connection part and the second swing connection part, and the swing motor 32 is connected to the correction component 4 through transmission parts such as bearings. More specifically, the two opposite sides of the correction component 4 are provided with coaxial rotating shafts, and are rotatably connected to the first swing connection part and the second swing connection part through the rotating shaft. The swing motor 32 is arranged on the side of the first connection part (of course, it can also be the second connection part) away from the correction component 4, and the swing motor 32 is connected to the rotating shaft, and the correction component 4 is driven to swing through the rotating shaft. The first swing connection part and the second swing connection part fix the correction component 4 from both sides, which can make the correction component 4 drive the camera 2 to swing more stably and improve the shooting effect.

[0035] For further information, please refer to Figure 3 As shown, in this embodiment, the deflection correction component 4 includes a deflection correction connection frame 41 and a deflection correction motor 42. The deflection correction connection frame 41 is movably arranged on the swing connection frame 31, specifically arranged between the first swing connection part and the second swing connection part of the swing connection frame 31, and is rotatably connected to both. The swing motor 32 is connected to the deflection correction connection frame 41, and the camera 2 is movably arranged on the deflection correction connection frame 41. The deflection correction motor 42 is connected to the camera 2 to drive the camera 2 to swing. At this time, the swing motor 32 drives the deflection correction motor 42 and the camera 2 to swing together with the first straight line as the axis, and at the same time, the deflection correction motor 42 drives the camera 2 to swing with the second straight line as the axis.

[0036] It is worth noting that, due to the provision of the deflection correction component 4, when the deflection correction component 4 drives the camera 2 to swing, the angle between the optical axis of the camera 2 and the first straight line will change. When performing multi-angle and large overlapping shooting, in order to ensure the accuracy of the three-dimensional data finally calculated by the computer, at least one photo taken in the vertical direction downward is often required. At this time, in order to ensure that the camera 2 can face downward at least for a moment during the swinging process, that is, the optical axis is parallel to the vertical direction, in this embodiment, the first straight line is perpendicular to the second straight line. Preferably, the optical axis of the camera is perpendicular to the second straight line. More preferably, the first straight line is perpendicular to and intersects with the second straight line, so that the rotation angle of the rotating shaft of the swing motor 32 is equal to the deflection angle of the second straight line when the deflection correction component 4 swings, so that the staff can more accurately control the swing of the deflection correction component 4. More preferably, the second straight line is perpendicular to and intersects with the optical axis of the camera 2. It can be made that the rotation angle of the rotating shaft of the deflection correction motor 42 is equal to the deflection angle of the optical axis when the camera 2 swings, so that the staff can more accurately control the swing of the camera 2.

[0037] Furthermore, in the present embodiment, a fixed frame 21 is provided on the camera 2, and a correction motor 42 is connected to the fixed frame 21. Specifically, the fixed frame 21 is fixedly connected to the camera 2, which protects the camera 2 and also acts as a buffer when it is hit. The correction connection frame 41 is in the shape of a rectangular frame, and has a first correction connection part and a second correction connection part relative to each other, and a third correction connection part and a fourth correction connection part relative to each other, wherein the first correction connection part and the second correction connection part are rotationally connected to the first swing connection part and the second swing connection part respectively. The third correction connection part and the fourth correction connection part are rotationally connected to the opposite sides of the fixed frame 21 respectively. The correction motor 42 is connected to the fixed frame 21 through a rotating shaft, and drives the fixed frame 21 to swing, thereby driving the camera 2 to swing. At the same time, the provision of the fixed frame 21 can also facilitate the loading and unloading of the camera 2, that is, when loading and unloading the camera 2, there is no need to operate parts such as the rotating shaft.

[0038] For further information, please refer to Figure 1-Figure 3As shown, in this embodiment, a shock absorbing assembly 5 is provided between the swing scanning assembly 3 and the main frame 1. During the flight, the aircraft may vibrate due to factors such as airflow, and the aircraft vibration may cause the camera 2 to vibrate, making the photographed photos blurry or distorted. In this embodiment, the shock absorbing assembly 5 is provided to reduce the influence of the aircraft vibration on the camera 2, so as to ensure the shooting quality.

[0039] For further information, please refer to Figure 1-Figure 3 As shown, in this embodiment, the shock absorbing assembly 5 includes a shock absorbing frame 51 and a shock absorber 52. The shock absorbing frame 51 has at least one group of relatively arranged connecting arms, each connecting arm is provided with a shock absorber 52, and the connecting arm is connected to the main frame 1 through the shock absorber 52, and the swing sweeping assembly 3 is connected to the shock absorbing frame 51. Specifically, the shock absorbing frame 51 includes a main body in the middle and connecting arms arranged around the main body, and the connecting arms are arranged in pairs, and the shock absorbing frame 51 is arranged above the swing connecting frame 31 and connected to the top of the swing connecting frame 31. Preferably, in order to ensure balance, the swing connecting frame 31 is arranged in the middle of the two relatively arranged connecting arms. The shock absorber 52 is arranged below the end area of ​​the connecting arm, and the main frame 1 is provided with a connecting portion for connecting with the shock absorber 52. That is, one end of the shock absorber 52 is connected to the connecting arm, and the other end is connected to the main frame 1, and the shock absorbing direction of the shock absorber 52 is parallel to the gravity direction. In this embodiment, the number of connecting arms is four, and they are arranged in pairs.

[0040] For further information, please refer to Figure 2 As shown, in this embodiment, the main frame 1 includes a top seat 11 and a base 12 that are arranged oppositely and at intervals, and a plurality of support rods 13, the two ends of each support rod 13 are connected to the top seat 11 and the base 12 respectively, and the plurality of support rods 13 are arranged around the accommodation space.

In specific implementation, the shock absorber 52 can be connected to the inner side of the support rod 13.

[0041] Embodiment 2:

[0042] The difference between this embodiment and embodiment 1 is that a lifting assembly 6 is further provided.

At the same time, the lifting assembly 6, the swing-sweep assembly 3 and the camera 2 are all provided in the accommodation space of the main frame 1. That is, the swing-sweep assembly 3 is connected to the main frame 1 through the lifting assembly 6, and the lifting assembly 6 is used to drive the swing-sweep assembly 3 to move compared with the main frame 1. Specifically, the lifting assembly 6 can drive the swing-sweep assembly 3 to and from the inside and outside of the accommodation space. In this embodiment, the swing-sweep assembly 3 is the same as the swing-sweep assembly 3 in embodiment 1. It is worth noting that in this embodiment, the shock absorbing assembly 5 is an optional setting. When the shock absorbing assembly 5 is not provided, the swing-sweep assembly 3 is directly connected to the lifting assembly 6. When the shock absorbing assembly 5 is provided, the swing-sweep assembly 3 is connected to the lifting assembly 6 through the shock absorbing assembly 5.

[0043] In some aircraft, the aerial swing-scanning camera device is arranged inside the cabin of the aircraft, and most cabins have an opening at the bottom. However, due to the different models of aircraft, the depth of the cabin is also different. If the cabin is too deep, the cabin wall will block the camera 2 of the aerial swing-scanning camera device inside, making it impossible to take pictures normally. In this embodiment, the lifting assembly 6 is arranged to adjust the position of the swing-scanning assembly 3 and the camera 2, so that they can move to other positions to avoid being blocked by the cabin wall, so that the swing-scanning camera device can be applied to more models of aircraft and has stronger adaptability.

That is, at least one support rod 13 is provided with a lifting assembly 6. And the movement direction of the swing sweep assembly 3 driven by the lifting assembly 6 is parallel to the support rod 13. In this way, during installation, it is only necessary to ensure that the position of the main frame 1 is correctly installed to ensure that the lifting assembly 6 can drive the swing sweep assembly 3 to move in the preset direction.

[0045] For further information, please refer to Figure 2 As shown, in this embodiment, the lifting includes a guide rail 61 and a lifting motor. The guide rail 61 is arranged on the support rod 13, specifically, the guide rail 61 is directly mounted on the side wall of the support rod 13 facing the accommodating space or directly integrated. The swing-sweep assembly 3 is movably arranged on the guide rail 61, and the lifting motor is arranged on the guide rail 61 and connected to the swing-sweep assembly 3. The lifting motor is used to drive the swing-sweep assembly 3 to move along the guide rail 61. The lifting motor is connected to the swing-sweep assembly 3 through a transmission component, so that the lifting motor can drive the swing-sweep assembly 3 to move along the guide rail 61 to adjust the position of the camera head.

[0046] For further information, please refer to Figure 2As shown, in this embodiment, a screw rod 62 parallel to the guide rail 61 is provided on the guide rail 61, a moving block 63 is sleeved on the screw rod 62, the moving block 63 is connected to the swing sweeping assembly 3, and the lifting motor is connected to the screw rod 62. When in use, the lifting motor drives the screw rod 62 to rotate so that the moving block 63 moves along the screw rod 62 to drive the swing sweeping assembly 3 to move.

[0047] Furthermore, in this embodiment, at least two of the plurality of support rods 13 are arranged opposite to each other, and the oppositely arranged support rods 13 are both provided with a lifting assembly 6. In this embodiment, there are two lifting assemblies 6, which are respectively arranged on two opposite support rods 13, so that the swing scanning assembly 3 is more stable during movement, avoiding affecting the shooting of the camera 2.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
