Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art through specific situations.
As shown in fig. 1, a facial expression capturing mask for performance is made of a mask body 100 and a band 200, the mask body 100 is made by modeling according to the facial contour and muscle of a specific actor, the mask body 100 is completely attached to the facial contour of the actor, and the mask body 100 is only customized for the specific actor.
As shown in fig. 2, the band 200 is a ring shape made of memory metal, and the band 200 can be installed at the back head of the head. The hoop 200 is customized for a specific actor, and the hoop 200 is made of memory metal, so that the hoop 200 can be restored to the original shape when being worn every time, and the hindbrain can be tightly attached every time. The inner wall of the band 200 may also add a protective cushion to increase comfort of wear. The edges of the band 200 are interwoven with a number of weft threads 220 via a number of warp threads 210 to provide added stability when wearing the mask. The top and the bottom of the mask body 100 are connected with the hoop 200 through the elastic rope (the structure diagram of the elastic rope is not shown), the elastic rope is fixed at the edge of the hoop 200 and can be detachably connected with the mask body 100, and after the hoop 200 and the mask body 100 are worn, the hoop 200 and the mask body 100 are tightly worn through the elastic rope, so that a problematic connection structure is provided; avoid the performance range big, cause the shake of mask, influence the pulling force of force sensor response.
As shown in FIG. 3, the mask body 100 is provided with a fabric frame 110 on the side adjacent to the face, and the fabric frame 110 includes: circumferential fibers 111 around the edge of the mask, medial axis fibers 112, and transverse fibers 113, the medial axis fibers 112 coinciding with the central axis of the face and connecting the circumferential fibers 111; transverse fibers 113 are located at the alar part of the nose and connect with the circumferential fibers 111 and the central axis fibers 112; the fabric frame 110 is adhered to the mask body 100 according to the contour of the face. The fiber frame 110 provides a tensioning force for the tensile fibers 310 connected to the multi-directional tension sensor 300.
As shown in FIGS. 1 and 4, the side of the mask body 100 adjacent the face is provided with multi-directional tension sensors 300 at the auditorium, eyebrow, eye orbit, 140, cheek, corner and chin areas 120, 130, 170, respectively. The auditorium 120, the eyebrow 130, the eye sockets 140, the cheeks 150, the mouth corners 160 and the chin 170 are all areas with large muscle changes during facial expression actions, and the multidirectional tension sensors 300 are arranged at the areas to effectively capture more accurate expression data. The position of the small sun within the dashed box in fig. 1 is the position where the multi-directional tension sensor 300 is disposed.
The multi-directional tension sensor 300 is of a sheet structure, one side of the multi-directional tension sensor 300 is adhered to the mask body 100 according to the outline of the mask body 100, and one side of the multi-directional tension sensor 300, which is close to the face, is coated with an adhesive so as to be accurately adhered to the surface of the skin and measure the movement rule of muscles.
At least three tension fibers 310 are connected to the edge of each multi-directional tension sensor 300, and at least one of the circumferential fibers 111, the middle axial fibers 112, and the transverse fibers 113 of the multi-directional tension sensor 300 is connected through the tension fibers 310. At least arranging a multi-directional tension sensor 300 at the eyebrow part 130, at the eyebrow part, at the eyebrow peak and at the eyebrow tail; at least four multidirectional tension sensors 300 are provided at the cheek 150 and at the orbit 140, respectively, since the amplitude of the muscle movement is greater here. At least one tension fiber 310 is connected between adjacent multi-directional tension sensors 300. The tension applied to the tension fiber 310 in different directions to which each multi-directional tension sensor 300 is connected is different by the movement of the facial muscles.
The positions and sensed values of all the multi-directional tension sensors 300 on the mask body 100 are used as an expression coordinate sequence. The mask body 100 can output different expression coordinate sequences of actors, and construct an expression database of a specific actor, wherein the expression database comprises at least 2000 expression coordinate sequences. Before or during the performance of the actor wearing the mask, each expression such as happiness, sadness, anger, fear, surprise and disgust is different from muscle movement, so that the values of the induced tension of the multi-directional tension sensor 300 are different. But for the same facial expression such as smile, the actor basically has little change in facial treatment, the coordinate sequence of each expression of the actor can be set in a range, and the expressive special effect is selected according to the range of the coordinate sequence of each expression in the later period of producing the special effect.
It should be noted that, when an actor makes an expression, the movement of the actor's facial muscles applies different tensions to the tension fibers 310 in different directions connected to each of the multi-directional tension sensors 300, and different expressions or even the sensed values of the multi-directional tension sensors 300 corresponding to each position in the same expression are changed, so that various expressions of the actor can be captured, thereby establishing an expression database of the actor proper.
The multi-directional tension sensor 300 of the present invention is symmetrically arranged along the central axis of the face, or the multi-directional tension sensor 300 is only arranged on one side of the central axis of the face. Correspondingly, the expression coordinate sequence of the actor is based on the value of the multidirectional tension sensor at the symmetrical position of the whole face, or the two sides are consistent by default and the induction value of one side is used as the reference.
In conclusion, the facial expression capturing mask provided by the invention can capture various expressions of actors, obtains the motion rules of facial muscles of the actors with different expressions through data statistics, constructs an expression database special for a specific actor, facilitates later-stage movie and television special effects and role facial animation, and reduces the cost of post-stage image processing.
The invention also provides an installation method of the facial expression capturing mask for performance, which comprises the following steps:
s1, fixing the hoop 200 at the back head of the head, and interweaving a plurality of warps 210 and wefts 220 to wrap the back head;
s2, coating an adhesive on the multidirectional tension sensor 300 on the mask body 100, and adhering the mask body 100 to the face, so that the tension sensor is accurately adhered to the muscle with large face movement amplitude;
s3, the top and bottom of mask body 100 are connected to hoop 200 by bungee cords to secure and tighten the mask.
In light of the foregoing description of the preferred embodiment of the present invention, it is to be understood that various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
