Description

Technical Field

[0001] The utility model relates to the technical field of expression and motion capture of animation characters, in particular to an expression and motion capture device for animation characters. Background Art

[0002] Animation character expression and motion capture equipment is used to capture the expressions and movements of real people or objects, and then convert them into digital data for use in the animation process. These devices can greatly improve the efficiency and realism of animation production, making the expressions and movements of animation characters more vivid and natural.

[0003] For the expression capture of animated characters, commonly used equipment includes facial capture systems and head-mounted facial expression capture equipment. Facial capture systems use cameras to capture the facial expressions of actors from different angles, and then analyze these data through computer algorithms to generate accurate facial animations.

[0004] For motion capture, commonly used equipment includes optical motion capture systems and inertial motion capture systems. Optical motion capture systems use infrared cameras to capture the movement trajectory of reflective markers attached to the actor, and then process this data through a computer to generate the character's movements. Inertial motion capture systems use sensors built into the actor's costume or props to capture movements without the need for external cameras.

[0005] After searching, the patent with announcement number CN211670915U discloses a facial expression capturer for animation production tools, including a capturer body, a height adjuster is provided on one side outer surface of the capturer body, a non-slip sleeve is provided on one side outer surface of the height adjuster, a movable connecting rod is provided on the upper end outer surface of the capturer body, a rotating telescopic rod is provided on one side outer surface of the movable connecting rod, a camera protector is provided on one side outer surface of the rotating telescopic rod, and a camera is provided on one side outer surface of the camera protector. The facial expression capturer for animation production tools described in the utility model can improve the mobility of the device through the designed movable connecting rod, can realize the all-round rotation of the device through the designed rotating telescopic rod, and make the device more manipulable, and can reduce the dust accumulation on the camera through the designed camera protector, thereby extending the service life of the camera and bringing better prospects for use.

[0006] The technical solution has the following problems:

[0007] Although the camera can capture the facial expressions of people through the height adjuster, it is not convenient to adsorb and fix the height adjuster on the desktop to prevent it from shaking and sliding, which is inconvenient. Utility Model Content
