Description

Technical Field

[0001] The utility model relates to the technical field of animation production equipment, in particular to an all-round character facial expression capturing device for animation production. Background Art

[0002] Animation production is a complex and meticulous process involving multiple steps and techniques. It's primarily categorized into two main categories: 2D and 3D. While these techniques differ, the basic process is similar, encompassing several key stages: determining the animation's theme, style, and audience; and developing a detailed production plan. This phase forms the foundation of animation production and provides direction for subsequent work. Based on the planned content, the script is written, defining the storyline, character design, and dialogue. The script is the core of animation production, determining both its content and presentation.

[0003] For example, the patent application number disclosed on the China Patent Network is: 202022018718.7, and the patent name is: A facial expression capture device, comprising: a support unit, which includes a counterweight and a connecting rod, and the two ends of the connecting rod are connected to the counterweight; a helmet body, which is mounted on the connecting rod of the support unit to form a first annular support structure and a second annular support structure on both sides of the helmet body, and the counterweight is located on the second annular support structure. The helmet body is used to be worn on the user's head and the user's face is facing the first annular support structure when worn; at least one lighting unit, which is movably arranged on the first annular support structure, for providing lighting for the face of the person in the helmet body; at least one image acquisition unit, which is arranged on the first annular support structure and opposite to the counterweight, and the lens of each image acquisition unit is facing the face of the person in the helmet body to capture the facial expression image of the person.

[0004] However, existing expression capture devices mainly collect user facial features through a single collection camera facing the user. The facial widths of different users are different, which affects the feature collection range. At the same time, when the user moves violently, the device located directly in front cannot effectively follow the movement, further affecting the collection effect.

[0005] Therefore, it is necessary to design and transform the all-round character facial expression capture equipment used in animation production. Utility Model Content

[0029] A capture camera 2 provided at the bottom of the front of the headband 1;

[0030] The number of capture cameras 2 is two and they are symmetrically arranged. The capture camera 2 is movably connected to the headband 1 through an adjustment structure 3. The adjustment structure 3 includes swing rods 4 movably connected to both sides of the top of the headband 1 through pins. One side of the swing rod 4 away from the headband 1 is connected to the capture camera 2. A transmission structure 5 is provided at the top of the headband 1, and the transmission structure 5 can drive the swing rod 4 to swing.

[0031] Refer to Figure 3 , the transmission structure 5 includes a connection frame 6 fixedly connected to the top of the headband 1. A bidirectional screw 7 is movably connected to the inside of the connection frame 6 through a bearing. Both the left and right sides of the surface of the bidirectional screw 7 are threadedly connected with screw sleeves 8. The screw sleeves 8 are located at the top of the swing rod 4. The bottom of the screw sleeve 8 is fixedly connected with a slide bar 9. One side of the slide bar 9 away from the screw sleeve 8 extends into the inside of the swing rod 4, and the swing rod 4 and the slide bar 9 are slidably connected. The right end of the bidirectional screw 7 penetrates to the right side of the connection frame 6 and is fixedly connected with a rotating wheel 10.

[0032] As a technical optimization scheme of the present utility model, by using the cooperation of the bidirectional screw 7 and the screw sleeve 8 and rotating the rotating wheel 10, the positions of the cameras on both sides can be adjusted simultaneously, realizing synchronous and precise adjustment, simplifying the adjustment process, improving work efficiency, and at the same time ensuring the consistency of the camera positions.

[0033] Refer to Figure 2, a guide bar 11 is fixedly connected inside the connecting frame 6. The guide bar 11 is located at the top of the bidirectional screw 7, and the bottom of the guide bar 11 extends into the inside of the screw sleeve 8. The screw sleeve 8 is slidably connected to the guide bar 11.

[0034] As a technical optimization scheme of the present utility model, by adding a guide bar 11 inside the connecting frame 6, a stable sliding track is provided for the screw sleeve 8, preventing the screw sleeve 8 from shifting or shaking during movement, improving the adjustment accuracy, and also extending the service life of the device and reducing the wear caused by long-term use.

[0035] Reference Figure 3 , on the side of the swing rod 4 away from the headband 1, a connecting rod 12 is fixedly connected. The side of the connecting rod 12 away from the swing rod 4 extends to the top of the capture camera 2 and is movably connected to the capture camera 2 through a bearing.

[0036] As a technical optimization scheme of the present utility model, by being movably connected to the capture camera 2 through a bearing, the camera can be adjusted at an angle within a certain range, increasing the flexibility of the capture camera 2, enabling it to better adapt to the subtle changes in the wearer's face, and improving the accuracy and authenticity of expression capture.

[0037] Reference Figure 4 , the top end of the connecting rod 12 penetrates through the swing rod 4 and extends to the top of the swing rod 4. A sleeve 13 is threadedly connected to the surface of the connecting rod 12 and is located at the top of the swing rod 4. A bearing ring 14 is fixedly connected to the surface of the sleeve 13. A pressing plate 15 is sleeved on the surface of the sleeve 13 and is located at the top of the bearing ring 14. The side of the pressing plate 15 away from the sleeve 13 extends to the bottom of the capture camera 2 through the front of the capture camera 2. When the sleeve 13 rises through the thread, the bearing ring 14 can be used to apply pressure to the pressing plate 15.

[0038] As a technical optimization scheme of the present utility model, by threadedly connecting the sleeve 13 to the connecting rod 12, when the sleeve 13 is rotated, the bearing ring 14 can be used to apply pressure to the pressing plate 15, thereby achieving the effect of positioning the capture camera 2.

[0039] Reference Figure 3 , an elastic pad 16 at the bottom of the capture camera 2 is fixedly connected to the surface of the pressing plate 15. The top of the elastic pad 16 is in contact with the surface of the capture camera 2, and the elastic pad 16 has elasticity.

[0040] As a technical optimization scheme of the present utility model, by fixedly connecting an elastic pad 16 to the surface of the pressing plate 15 and the elastic pad 16 being in contact with the surface of the capture camera 2, not only a soft buffering effect is provided, but also the camera is protected from impact and scratches.

[0041] Working principle and usage process of the present utility model: First, the user wears the headband 1 on the head, ensuring that the headband 1 is stable and comfortable. The design of the headband allows it to adapt to heads of different sizes. There are two symmetrically arranged capture cameras 2 on the headband 1, which are movably connected to the headband 1 through an adjustment structure 3. Initially, the user may need to rotate the runner 10 in the transmission structure 5 to adjust the position of the camera to adapt to their facial features or specific shooting requirements. The core of the transmission structure 5 is a bidirectional screw 7, which is movably connected to the connection frame 6 at the top of the headband 1 through bearings. On the left and right sides of the bidirectional screw 7, there are screw sleeves 8 threadedly connected respectively. The bottom of the screw sleeve 8 is connected to a slide bar 9, and the slide bar 9 is slidably connected to the swing bar 4. When the user rotates the runner 10, the bidirectional screw 7 will rotate, driving the screw sleeves 8 on both sides to move in opposite directions simultaneously. Since the screw sleeve 8 is connected to the slide bar 9 at the top of the swing bar 4, the movement of the screw sleeve 8 will drive the swing bar 4 to swing around the pin shaft, thereby adjusting the angle of the capture camera 2. In addition to the large-range angle adjustment through the transmission structure 5, each capture camera 2 is also movably connected to the swing bar 4 through a connecting rod 12, allowing for more subtle angle adjustment. The user can rotate the sleeve 13 on the connecting rod 12 and use the principle of screw descent to push the bearing ring 14 and the pressure plate 15 downward, thereby relieving the pressure on the capture camera 2 and enabling the capture camera 2 to rotate at the bottom of the connecting rod 12. When the adjustment of the capture camera 2 is completed, reverse-operate the sleeve 13 to use the pressure plate 15 to squeeze the capture camera 2. The rubber pad 16 on the pressure plate 15 ensures the stable fixation of the camera, and at the same time, the elasticity of the rubber pad 16 also provides a buffering effect.

[0042] In summary: The all-round facial expression capture device for animation production can capture the facial expressions of the wearer more comprehensively through two symmetrically arranged capture cameras 2, reducing blind spots. Through the adjustment structure 3, the camera can be flexibly adjusted in angle according to the facial features of the wearer, ensuring the best shooting angle regardless of how the face moves.
