Description

Technical Field

[0001] The present invention relates to the field of camera technology, and 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 naked eye 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 gives feedback through verbal expression. This is not intuitive, specific, lacks quantification, and is difficult to understand.

[0003] In recent years, with the slogan of "Technology helps sports", it is very important to use technology to visualize and quantify sports performance to improve the level of athletes. Swimming has its own particularity, and there has been a lack of effective, simple and relatively low-cost solutions for synchronously shooting high-quality swimming videos above and below the water.

[0004] The equipment available on the market for swimming photography mainly includes mobile phones, sports 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 shoot above and underwater at the same time: mobile phones, sports cameras, and professional cameras can only shoot above or underwater at the same time, while underwater drones and underwater boosters cannot shoot above water videos simultaneously; fixed camera shooting has a single angle and a limited shooting range;

[0006] 2. It is difficult to control the shooting angle and moving speed for underwater dynamic shooting: the data cable of the underwater drone will affect the normal operation of the swimming pool and is not suitable for application; the underwater booster requires the photographer to be able to swim and dive as well as control the camera in the water, which is not only difficult and difficult to operate, 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 and requires a considerable number of professionals to set up, debug and control the underwater track. It cannot meet the needs of mass swimming, daily training of professional teams and other scenarios.

[0008] 4. Mobile shooting cannot take into account stability, shooting quality and equipment safety at the same time, which makes video shooting difficult, poor in quality and high in equipment risk. 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. Summary of the invention

[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, which support real-time preview and synchronous shooting of above-water and underwater perspectives. The photographer can dynamically adjust the angle and moving speed without going into the water, and shoot high-quality dual-perspective video, which is convenient for later analysis and improvement of the swimmer's movements.

[0011] In order to achieve the above-mentioned object of the invention, the present invention provides a camera support unit, comprising:

[0012] floating body;

[0013] A main bracket is arranged to penetrate the top and bottom surfaces of the floating body and is fixedly connected to the floating body. The main bracket is divided into an above-water section and an underwater section. An underwater camera installation position is arranged 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, an above-water camera installation position is arranged on the upper end thereof, and a lower end thereof is fixedly connected to the main bracket.

[0015] According to a technical solution of the present invention, a water divider is arranged on the bottom surface of the floating body, the water divider is arranged perpendicular to the floating body, 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 present invention, it also includes:

[0017] A support rod, arranged between the above-water section and the above-water camera bracket, with two ends thereof 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 invention, the main support further includes:

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

[0022] The second handle is arranged below the first handle, and the plane where the main bracket and the water 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 support.

[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 above-water camera unit, arranged on the above-water 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 the preview image back in real time.

[0028] According to a technical solution of the present invention, the dual-view shooting device also includes a communication unit, and the communication unit 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 synchronous control and display unit can realize the synchronous shooting of the above-water and underwater photography units, and the shooting pictures of the above-water and underwater photography units can be previewed in real time through the synchronous control and display unit, so as to realize the real-time preview and synchronous shooting of the above-water and underwater perspectives. Only one photographer is needed without going into the water to easily adjust the shooting angle and moving speed, and shoot stable, above-water and underwater dual-perspective synchronous 4K / 30fps video.

[0033] 2. Both the above-water photography unit and the underwater photography unit use customized waterproof gyro 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, support 4K at least 30fps ultra-high-definition video acquisition, encoding and decoding capabilities, to ensure that the swimmer's underwater and above-water postures in the video are clearly visible, which is convenient for later analysis and improvement of above-water and underwater movements and training of artificial intelligence large models (LargeVideo 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 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. The water divider can help maintain the moving 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 of the float, it is ensured that the camera can move synchronously and smoothly in the water and on the water surface, and the average speed can reach 1.67 meters / second (30 seconds to shoot a 50-meter national standard swimming pool distance) to meet the shooting needs of many indoor scenes including competitive swimming.

DETAILED DESCRIPTION

[0041] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0042] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on 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, and the present invention is not particularly 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 support the above-water camera unit 9 and the underwater camera unit 10. The above-water camera unit 9 is arranged above the water surface to shoot the swimmer's above-water posture. The underwater camera unit 10 is arranged below the water surface to shoot the swimmer's underwater posture. Both the above-water camera unit 9 and the underwater camera unit 10 are waterproof cameras 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 sets a display unit with an integrated split-screen synchronous preview display for the shooter to dynamically adjust the shooting angle and speed, and reserve an interface for subsequent access to the video analysis model. The communication unit 5 is electrically connected to the above-water camera unit 9, the underwater camera unit 10 and the synchronous control and display unit 6, and transmits the real-time preview image and video data collected by the underwater camera unit 10 to the synchronous control and display unit 6 to preview the above-water and underwater video images in real time, and synchronously record the above-water and underwater videos. The synchronous control and display unit 6 integrates the display unit and the synchronous control unit, thereby reducing the number of parts and the weight of the shooting equipment, thereby improving its flexibility of use.

[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 comprises: a floating body 12, a main support 1, an above-water camera support 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 arranged on the bottom surface of the floating body 12 , and the water divider 7 is arranged 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. While providing sufficient buoyancy support, it effectively reduces the water resistance during mobile shooting, overcomes the vibration and displacement of the camera support unit caused by the impact of irregular water flow in the swimming pool, and ensures 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 angle 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 arranged to penetrate the top and bottom surfaces of the floating body 12 and is fixedly connected to the floating body 12. The main bracket 1 is divided into an above-water section and an underwater section. An underwater camera installation position is arranged 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 , an water camera installation position is arranged on the upper end of the water camera bracket 3 , and the lower end of the water camera bracket 3 is fixedly connected to the main bracket 1 .

[0053] like Figure 3 As shown, the locking unit 13 is disposed at the connection between the water camera bracket 3 and the main bracket 1, and is used to lock the relative position of the water 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, and the two ends of the locking unit 13 are respectively connected to the water camera bracket 3 and the main bracket 1. The water camera bracket 3 and the main bracket 1 are connected through the locking unit 13, and the angle between the water camera bracket 3 and the main bracket 1 can be adjusted and locked through the locking unit 13.

[0054] The support rod 4 is arranged between the above-water section and the above-water camera bracket 3, and the two ends of the support rod 4 are respectively fixedly connected to the above-water section and the above-water camera bracket 3. The support rod 4 is a telescopic rod, and the length can be finely adjusted. The support rod 4 is used to strengthen the structural strength of the dual-viewing angle shooting device to prevent the locking unit 13 from breaking or changing the angle.

[0055] The main support 1 is provided with a first handle 2 for the photographer to hold and move, 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 the first handle 2 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 arranged 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, the plane where the main bracket 1 and the above-water camera bracket 3 are located is rotated by the second handle 8, so that the shooting effects of the above-water and underwater camera units can be adjusted.

[0058] A synchronous control and display device installation platform is provided on the upper part of the main support 1. The synchronous control and display device installation platform and the main support 1 are at a certain angle to facilitate the photographer's viewing. The synchronous control and display device installation platform is used to install a synchronous control and display unit 6 (such as an iPad, an Android tablet computer, 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 through 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 gyro electronic image stabilization cameras, support real-time image transmission (wired connection is used underwater, wired or wireless connection is used above water), 1080P high-definition split-screen preview, built-in TF memory card, both support 4K level, 30fps starting video shooting and acquisition, encoding and decoding capabilities, and have gyro electronic image stabilization (EIS) function.

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

[0061] The power source 11 is a 12V large-capacity waterproof mobile power source, which is arranged on the main support 1 and can be arranged above the floating body 12 .

[0062] When using the dual-view shooting device, adjust the angles of the water camera unit 9 and the underwater camera unit 10. The photographer holds the dual-view shooting device and places it in the water beside the swimming pool (for example, lane 1 of a national standard swimming pool). The float 12 provides buoyancy to keep the water camera unit 9 at a height of about 80 cm above the water surface and the underwater camera unit 10 at a depth of about 70 cm below the water surface. With the help of the synchronization control unit 6, the video data transmission unit sends instructions to the water camera unit 9 and the underwater camera unit 10 to start and end video shooting. The photographer holds the first handle 2 and pushes the camera support unit to make the water camera unit 9 and the underwater camera unit 10 move in parallel with the swimming direction of the swimmer in the designated swimming lane (for example, lane 2 of a national standard swimming pool), maintaining a relatively fixed shooting distance and angle; the preview images of the water camera unit 9 and the underwater camera unit 10 are transmitted back to the synchronization control and display unit 6 in real time through the communication unit 5. After the video recording is completed, the collected video is downloaded to the synchronization control and display unit at high speed through the communication unit 5 for storage and review. A single recording does not exceed 50 meters.

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