Description

Technical Field

[0001] This utility model relates to a portable shooting device, belonging to the technical field of photographic and video equipment. Background Technology

[0002] This involves capturing motion and recording video using professional equipment, such as industrial cameras, with high resolution, high frame rate, and high transmission performance. It can be used for various types of motion capture; high resolution allows for high-quality video recording, high frame rate captures details in fast-moving scenes, and high transmission performance enables storage of the captured content.

[0003] In traditional motion capture video recording, filmmakers often mount their equipment on tripods for fixed shooting. When changing shooting positions, they can only lift the tripod and equipment by gripping its legs. Since the tripod and equipment are quite heavy and bulky, especially over long distances or with frequent position changes, relying solely on arm strength is physically demanding and can negatively impact shooting quality. Some filmmakers fix the equipment around the perimeter of the location, but this is limited by space constraints, the inability to reuse equipment, and security concerns regarding equipment storage. Furthermore, exporting and storing the captured footage is another crucial factor. Based on these issues, we propose a portable shooting device. Utility Model Content

[0004] The purpose of this invention is to provide a mobile shooting device that allows the shooting device to be moved without the need for wired connections such as network cables, power cords, or synchronizers during shooting, thus enabling flexible shooting, high shooting efficiency, and good shooting results.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A portable shooting device includes a housing, inside which a power supply and a host are installed. The selection of the host needs to consider weight, performance, and support for 10 Gigabit wired networks and high-speed wireless networks. Here, a small host, such as a Mac mini, is used, supporting 10 Gigabit wired network connection for connection with industrial-grade professional cameras. This is because industrial-grade cameras can only achieve full-function motion capture video acquisition with a 10 Gigabit wired network connection. Simultaneously, it also needs to support high-speed wireless networks for transmitting the acquired data. A portable power supply is used, and the host is electrically connected to the power supply to power the host. A column is vertically installed on the top of the housing. A robotic arm is rotatably mounted at the top of the column, allowing the robotic arm to rotate horizontally. A fixing device is hinged to the other end of the robotic arm, which can fix the shooting device in place. The shooting device can be adjusted to multiple angles through the robotic arm and the fixing device. The shooting device is electrically connected to both the host and the power supply, which provides power. The video information acquired by the shooting device can be transmitted to the host in real time. A wireless communication device using 5G is installed on the side wall of the column. The CPE device can convert 5G signal network into WIFI signal. The wireless communication device is electrically connected to the power supply device to provide power to the wireless communication device. The host can access the private network through the WIFI signal of the wireless communication device. The host can transmit the video information collected by the shooting device to the relay server for analysis and processing through the wireless communication device. At the same time, it can also receive the processing results returned by the relay server. The bottom of the box is equipped with casters for easy movement of the box. The casters are equipped with a braking device to easily fix the movable shooting device at any time and stabilize the shooting process.

[0006] In the aforementioned portable shooting device, a display is installed on the side wall of the column. The display is electrically connected to the host and the power supply. The display can display host information, which facilitates operation and observation of the shooting process.

[0007] In the aforementioned movable shooting device, the side wall of the column is provided with a sleeve-type bearing seat, and one end of the display support rod is hinged to the back of the display so as to rotate up and down. The other end of the display support rod is connected to the sleeve-type bearing seat through a rotating shaft, so that the display can rotate horizontally and the display can be adjusted at multiple angles. When one person is adjusting the working angle of the shooting equipment, the display can be rotated to a suitable position, and the shooting equipment can be adjusted while looking at the framing effect on the display.

[0008] The aforementioned mobile shooting device includes a slot with a top opening inside the column. An adjustable support column is inserted into the slot, with its top extending out of the slot and connecting to one end of a robotic arm. The side wall of the adjustable support column has multiple threaded holes evenly arranged vertically. A through hole is formed through the side wall of the slot, and a limiting component is installed through the through hole. The end of the limiting component is screwed into the corresponding threaded hole through the through hole, allowing the height of the adjustable support column to be adjusted as needed. The design, modified to a telescopic mode, provides a higher shooting position during motion capture video recording, enabling a wider shooting range and less susceptibility to obstruction. Considering the need for the mobile shooting vehicle to enter and exit different shooting spaces and the resulting door height restrictions (compared to a common door frame height of 1.9m), the adjustable support column height can reduce the overall vehicle height to below 1.9m. Because accessibility was considered in the design, this device can fit through most building doors when not raised.

[0009] The aforementioned movable shooting device includes a robotic arm comprising a first arm, a second arm, and a third arm. The first arm has a first rotary joint and a second rotary joint connected to its two ends respectively. A shaft is provided at the top of the adjustable support column. The first rotary joint is rotatably mounted on the shaft, allowing it to rotate horizontally along the shaft. The second rotary joint is connected to one end of the second arm, and the other end of the second arm is connected to a third rotary joint. The third rotary joint is connected to one end of the third arm, and the other end of the third arm is provided with a fixing device. The first arm, second arm, and third arm are connected via the first rotary joint, the second rotary joint, and the third rotary joint, allowing the first arm, second arm, and third arm to be adjustable and extended at multiple angles.

[0010] In the aforementioned movable shooting device, the back surface of the fixed device is provided with a hinged ear plate, and the end of the third arm is rotatably mounted with a hinge part. The hinged ear plate is hinged to the side of the hinge part, so that the fixed device can rotate up and down and left and right to adjust the shooting angle.

[0011] The aforementioned movable shooting device has a handle at the bottom of the fixing device. The handle is an extended and adjustable handle for easy gripping and adjustment of the shooting angle.

[0012] In the aforementioned movable shooting device, an operating table is provided on the side wall of the column in a horizontal direction. A pull-out keyboard rack is installed at the bottom of the operating table. A sliding groove is provided on the side wall of the pull-out keyboard rack, and a mouse tray is slidably installed in the sliding groove. A keyboard and a mouse are respectively placed on the pull-out keyboard rack and the mouse tray, and the keyboard and mouse are connected to the host.

[0013] In the aforementioned movable shooting device, the mouse holder has a mouse fixing part on the side wall away from the pull-out keyboard tray, which facilitates fixing the mouse position and prevents the mouse from falling when moving.

[0014] The aforementioned portable shooting device has a baffle inside the housing, with the main unit and power supply placed on the upper and lower sides of the baffle respectively, increasing the storage space of the housing. The side wall of the housing has heat dissipation holes, which reduces weight and facilitates heat dissipation, preventing the temperature inside the housing from getting too high.

[0045] The working principle of one embodiment of this utility model is as follows: During use, this utility model can be moved to a designated shooting location for fixed or mobile shooting. When capturing motion video, it allows for a higher shooting position, a wider shooting range, and less susceptibility to obstruction. Considering that the mobile shooting vehicle needs to enter and exit different shooting spaces and may encounter door height restrictions (compared to a common door frame height of 1.9m), the adjustable support column 14 is designed to lower the overall vehicle height to below 1.9m.
