Description

Technical Field

[0001] The utility model relates to the technical field of camera photography, in particular to a camera support unit and dual-viewing angle shooting equipment. Background Art

[0002] Traditional swimming training mainly relies on the coach's experience and visual judgment. The coach stands by the pool or goes into the water to observe the swimmer's posture and movement performance above or below the water, and then provides feedback through verbal expression. This is not intuitive, specific, lacks quantification, and is difficult to understand.

[0003] In recent years, with the advent of the "Technology Empowers Sports" slogan, the visualization and quantification of athletic performance through technological means has become crucial for improving athletes' performance. Swimming, with its unique characteristics, has lacked an effective, simple, and relatively low-cost solution for simultaneously capturing high-quality swimming videos both above and below the surface.

[0004] The devices available on the market for swimming photography mainly include mobile phones, action cameras, professional cameras, underwater cameras, underwater drones, underwater boosters, etc. However, these devices have many limitations, as follows:

[0005] 1. Single viewing angle, unable to capture both above-water and underwater footage simultaneously: Mobile phones, action cameras, and professional cameras can only capture above-water or underwater footage simultaneously, while underwater drones and underwater boosters cannot simultaneously capture above-water footage. Fixed camera positions limit the viewing angle and shooting range.

[0006] 2. Underwater dynamic shooting is difficult to control the shooting angle and movement speed: The data cable of the underwater drone will affect the normal operation of the pool, which is not suitable for use. Underwater boosters require the photographer to not only swim and dive but also be able to control the camera underwater, which is not only difficult and impractical, but also poses a safety hazard.

[0007] 3. Professional equipment is expensive, costly, and complex to operate. It can only be used in large-scale, high-level events. It requires a considerable number of professionals to set up, debug, and control the underwater track, and cannot meet the needs of scenarios such as public swimming and daily training for professional teams.

[0008] 4. Mobile filming cannot balance stability, shooting quality, and equipment safety, resulting in difficult and poor-quality video shooting and high equipment risks. It is also difficult to achieve high-speed dynamic synchronous shooting from above-water and underwater perspectives. In order to match the speed of high-level swimmers, mobile camera shooting often needs to compromise on shooting stability, resulting in severe video shaking and uncontrollable shooting angles.

[0009] The above problems make it difficult to obtain high-quality synchronized dual-view swimming videos, which limits the digitization of swimming and hinders the rapid development of swimming training and teaching. Utility Model Content

[0010] In order to solve the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a camera support unit and a dual-perspective shooting device that supports real-time preview and synchronous shooting of above-water and underwater perspectives. The photographer can dynamically adjust the angle and movement speed without going into the water, and shoot high-quality dual-perspective videos, which is convenient for later analysis and improvement of the swimmer's movements.

[0011] To achieve the above-mentioned purpose of the utility model, the utility model provides a camera support unit, comprising:

[0012] floating body;

[0013] A main bracket is provided through the top and bottom surfaces of the float and is fixedly connected to the float. The main bracket is divided into an above-water section and an underwater section. An underwater camera installation position is provided at the end of the underwater section of the main bracket.

[0014] The above-water camera bracket is arranged on one side of the main bracket, the upper end of which is provided with an above-water camera installation position, and the lower end of which is fixedly connected to the main bracket.

[0015] According to a technical solution of the present invention, a water divider is provided on the bottom surface of the float, the water divider is provided perpendicular to the float, and the water divider is coplanar or parallel to the plane where the above-water camera bracket is located.

[0016] According to a technical solution of the utility model, it also includes:

[0017] A support rod is provided between the above-water section and the above-water camera bracket, with its two ends fixedly connected to the above-water section and the above-water camera bracket respectively;

[0018] The locking unit is arranged at the connection between the above-water camera bracket and the main bracket.

[0019] According to a technical solution of the present invention, the support rod is a telescopic rod.

[0020] According to a technical solution of the present utility model, the main bracket further includes:

[0021] A first handle is provided at the upper end of the main support, wherein the first handle is coplanar with the plane where the main support and the underwater camera support are located;

[0022] The second handle is arranged below the first handle, and the plane where the main bracket and the underwater camera bracket are located is perpendicular to the second handle.

[0023] According to a technical solution of the present invention, a synchronous control equipment installation platform is provided on the upper portion of the main bracket.

[0024] According to one aspect of the present invention, there is provided a dual-viewing angle shooting device including the camera support unit as described above, comprising:

[0025] An underwater camera unit is arranged on the underwater camera installation position;

[0026] An underwater camera unit is arranged on the underwater camera installation position;

[0027] The synchronous control and display unit is electrically connected to the underwater camera unit and the above-water camera unit, and is used to control the above-water camera unit and the underwater camera unit to synchronously shoot and transmit preview images in real time.

[0028] According to a technical solution of the present invention, the dual-view shooting device further includes a communication unit, which is connected to the above-water camera unit, the underwater camera unit and the synchronous control and display unit.

[0029] According to a technical solution of the present invention, the above-water camera unit and the underwater camera unit are both anti-shake cameras.

[0030] According to a technical solution of the present invention, the dual-view shooting device also includes a power supply, and the power supply is arranged on the main bracket.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The sync control and display unit enables simultaneous shooting with both the above- and underwater camera units. Real-time split-screen preview of the footage from both units is provided via the sync control and display unit, enabling real-time preview and simultaneous shooting from both perspectives. With just one photographer, and without entering the water, they can easily adjust the shooting angle and movement speed to capture stable, synchronized 4K / 30fps video from both perspectives.

[0033] 2. Both the above-water and underwater photography units utilize customized waterproof, gyroscopic, and electronically stabilized cameras. They support real-time image transmission (wired connection underwater, wired or wireless connection above water), 1080P HD split-screen preview, a built-in TF memory card, and support for 4K ultra-HD video capture and encoding at at least 30fps. This ensures clear visibility of the swimmer's underwater and above-water postures in the video, facilitating later analysis and improvement of both above-water and underwater motions, as well as training of the Large Video Model.

[0034] 3. The camera support unit is designed based on fluid mechanics and physics. The float is made of high-density EVA material, which has the characteristics of high buoyancy, low shape resistance, and non-deformation. It provides sufficient buoyancy support while effectively reducing the water resistance during mobile shooting, overcoming the vibration and displacement of the camera support unit caused by the impact of irregular water flow in the swimming pool, and ensuring the stability of the camera during dynamic shooting. The water divider can help maintain the movement direction of the equipment in the water, making it easier for the photographer to fix the shooting angle. By setting the float on the main bracket and the water divider on the bottom surface of the float, it is ensured that the camera can move synchronously and smoothly in the water and on the water surface, with an average speed of 1.67 meters per second (a 50-meter national standard swimming pool distance can be shot in 30 seconds), meeting the shooting needs of many indoor scenes including competitive swimming.

DETAILED DESCRIPTION

[0041] The description of the embodiments in this specification should be combined with the corresponding drawings, which should be considered a complete part of this specification. In the drawings, the shapes and thicknesses of the embodiments may be exaggerated and indicated for simplicity or convenience. Furthermore, the various structural components in the drawings will be described separately. It is worth noting that components not shown in the drawings or not described in words are known to those of ordinary skill in the art.

[0042] The description of the embodiments herein and any references to directions and orientations are for ease of description only and are not to be construed as limiting the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination. The present invention is not specifically limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0043] like Figures 1 to 3 As shown, the present invention proposes a dual-view shooting device, including: an above-water camera unit 9, a camera support unit, an underwater camera unit 10, a communication unit 5, a synchronous control and display unit 6, a video data transmission unit, and a power supply 11.

[0044] The camera support unit is designed based on fluid mechanics and physics to ensure that the above-water camera unit 9 and the underwater camera unit 10 can move synchronously and smoothly in the water and on the water surface, and supports the above-water camera unit 9 and the underwater camera unit 10. The above-water camera unit 9 is set above the water surface and is used to shoot the swimmer's above-water posture. The underwater camera unit 10 is set below the water surface and is used to shoot the swimmer's underwater posture. Both the above-water camera unit 9 and the underwater camera unit 10 are waterproof cameras equipped with gyroscope electronic image stabilization technology, and together with the camera support unit, they process the vibrations generated by the impact of water flow. The synchronous control and display unit 6 is used to control the above-water camera unit 9 and the underwater camera unit 10 to shoot synchronously and transmit the preview image back in real time. At the same time, the synchronous control and display unit 6 is provided with a display unit with an integrated split-screen synchronous preview display, allowing the photographer to dynamically adjust the shooting angle and speed, and reserves an interface for subsequent access to the video analysis model. Communication unit 5 is electrically connected to surface camera unit 9, underwater camera unit 10, and synchronization control and display unit 6. It transmits real-time preview images and video data captured by underwater camera unit 10 to synchronization control and display unit 6, allowing for real-time preview of surface and underwater video images and simultaneous recording of both. Synchronization control and display unit 6 integrates the display unit and synchronization control unit into one, reducing the number of components and weight of the camera, thereby increasing its flexibility.

[0045] According to actual on-site usage, the use of dual-view shooting equipment can achieve a stable shooting speed of an average of 1.67 meters per second (a 50-meter national standard swimming pool distance can be shot in 30 seconds), meeting the shooting needs of many indoor scenes including competitive swimming.

[0046] The camera support unit includes: a float 12, a main bracket 1, an above-water camera bracket 3, a support rod 4, a locking unit 13, a first handle 2, a second handle 8, and a synchronous control and display unit installation platform.

[0047] A water divider 7 is provided on the bottom surface of the floating body 12 . The water divider 7 is provided perpendicular to the floating body 12 . The water divider 7 is coplanar or parallel to the plane where the above-water camera bracket 3 is located.

[0048] The float 12 is made of high-density EVA material, which has the characteristics of large buoyancy, small shape resistance and not easy to deform. It provides sufficient buoyancy support while effectively reducing the water resistance during mobile shooting, overcoming the vibration and displacement of the camera support unit caused by the impact of irregular water flow in the swimming pool, and ensuring the stability of the camera during dynamic shooting.

[0049] The water divider 7 can help maintain the moving direction of the device in the water, keep the dual-view shooting device stable, facilitate the photographer to fix the shooting angle, reduce the resistance of the dual-view shooting device during operation, and prevent large angular deviations during movement.

[0050] By providing the float 12 on the main support 1 and the water divider 7 provided on the bottom surface of the float 12, it is ensured that the camera can move synchronously and smoothly in the water and on the water surface.

[0051] The main bracket 1 is set through the top and bottom surfaces of the float 12 and is fixedly connected to the float 12. The main bracket 1 is divided into an above-water section and an underwater section. An underwater camera installation position is set at the end of the underwater section of the main bracket 1.

[0052] The water camera bracket 3 is arranged on one side of the main bracket 1 , the upper end of the water camera bracket 3 is provided with a water camera installation position, and the lower end of the water camera bracket 3 is fixedly connected to the main bracket 1 .

[0053] like Figure 3 As shown, a locking unit 13 is provided at the connection between the underwater camera bracket 3 and the main bracket 1, and is used to lock the relative position of the underwater camera bracket 3 and the main bracket 1. In some embodiments of the present invention, the locking unit 13 can be a telescopic rod with a locking function, with both ends of the locking unit 13 connected to the underwater camera bracket 3 and the main bracket 1, respectively. The underwater camera bracket 3 and the main bracket 1 are connected via the locking unit 13, and the angle between the underwater camera bracket 3 and the main bracket 1 can be adjusted and locked via the locking unit 13.

[0054] Support rod 4 is positioned between the above-water section and the above-water camera bracket 3. Its ends are fixedly connected to the above-water section and the above-water camera bracket 3, respectively. Support rod 4 is a telescopic rod with fine-tunable length. Support rod 4 serves to strengthen the dual-view camera's structural strength and prevent breakage or angle shifting at the locking unit 13.

[0055] The main bracket 1 is provided with a first handle 2 for the photographer to move the bracket by hand, and a second handle 8 for the photographer to adjust the shooting angle.

[0056] The first handle 2 is disposed at the upper end of the main support 1, and is coplanar with the main support 1 and the underwater camera support 3. In some embodiments of the present invention, the lower end of the first handle 2 is hinged to the upper end of the main support 1, and the angle between the first handle 2 and the main support 1 can be adjusted by rotating the first handle 2.

[0057] The second handle 8 is arranged below the first handle 2, and the plane where the main bracket 1 and the above-water camera bracket 3 are located is perpendicular to the second handle 8. The second handle 8 is used to adjust the plane where the main bracket 1 and the above-water camera bracket 3 are located. During use, by rotating the plane where the main bracket 1 and the above-water camera bracket 3 are located by the second handle 8, the shooting effects of the above-water and underwater camera units can be adjusted.

[0058] A synchronous control and display device mounting platform is located above the main support 1. This platform is angled relative to the main support 1 to facilitate viewing for the photographer. This platform is used to mount a synchronous control and display unit 6 (e.g., an iPad, Android tablet, etc.).

[0059] The above-water camera unit 9 and the underwater camera unit 10 are respectively arranged on the above-water camera installation position and the underwater camera installation position. The above-water camera unit 9 and the underwater camera unit 10 can be installed on the above-water camera installation position and the underwater camera installation position via a mechanical pan-tilt head, which is convenient for adjusting the installation and fixing the angle. The above-water camera unit 9 and the underwater camera unit 10 both use customized waterproof gyroscope electronic image stabilization cameras, support real-time image transmission (wired connection underwater, wired or wireless connection above water), 1080P high-definition split-screen preview, built-in TF memory card, both support 4K-level, 30fps starting video shooting, acquisition, encoding and decoding capabilities, and have gyroscope electronic image stabilization (EIS) function.

[0060] The communication unit 5 is electrically connected to the underwater camera unit 10, the surface camera unit 9 and the synchronous control and display unit 6. In one embodiment of the present invention, the communication unit 5 is a gigabit wireless router, which is wirelessly connected to the surface camera unit 9 and wiredly connected to the underwater camera unit 10.

[0061] The power supply 11 is a 12V large-capacity waterproof mobile power supply, which is arranged on the main bracket 1 and can be arranged above the float 12.

[0062] When using a dual-view camera, the angles of the above-water camera unit 9 and the underwater camera unit 10 are adjusted. The photographer holds the dual-view camera in the water near a swimming pool (e.g., lane 1 of a national standard swimming pool). The float 12 provides buoyancy, keeping the above-water camera unit 9 approximately 80 centimeters above the water surface and the underwater camera unit 10 approximately 70 centimeters below the water surface. With the help of the synchronization control unit 6, the video data transmission unit issues commands to the above-water camera unit 9 and the underwater camera unit 10 to start and end video recording. The photographer holds the first handle 2 and pushes the camera support unit to synchronize the above-water camera unit 9 and the underwater camera unit 10 with the swimming direction of the swimmer in the designated lane (e.g., lane 2 of a national standard swimming pool), maintaining a relatively fixed shooting distance and angle. Preview images of the above-water camera unit 9 and the underwater camera unit 10 are transmitted back to the synchronization control and display unit 6 in real time via the communication unit 5. After the video recording is completed, the captured video is downloaded to the synchronization control and display unit 6 at high speed via the communication unit 5 for storage and playback. A single recording does not exceed 50 meters.

[0063] After being analyzed and processed by professional swimming coaches, underwater and above-water videos of different swimming styles can be used to train swimming video analysis models. Through artificial intelligence (AI)-assisted swimming training and teaching, it can help swimming enthusiasts and professional swimmers improve their technical movements and improve their performance.
