Description

TECHNICAL FIELD

[0001] The present application relates to the field of animation, in particular to a two-dimensional animation production method and device based on somatosensory technology. BACKGROUND

[0002] With the development of computer technology, the demand for animation production in the fields of new media, advertising, film and television, games, digital display, etc. is also increasing. Because two-dimensional animation does not need to produce high-precision complex models, draw textures and set material lights like three-dimensional animation, the preparation process is relatively less, and the two-dimensional animation scene is in a static two-dimensional plane, and the near and far layers can also be drawn separately according to requirements, so that a rich scene can be quickly created. The overall production cycle and production cost are much lower than three-dimensional animation production, and the overall market demand is large.

[0003] A large number of human characters are often needed in two-dimensional animation, and animation producers need to produce a large number of running, jumping, waving arms, kicking legs and other action frames around these human characters. In addition to traditional hand-drawn production of sequence frames, there are many ways to produce animation digitally. Among them, one type of scheme uses the method of binding two-dimensional human characters to produce animation. This scheme does not require the producer to draw each frame of human action, but through the binding of the skeleton to perform skinning and bone weight assignment operations, and then through the skeleton to pull the two-dimensional human character image to make various actions, on this basis, to realize the production of various action animations of two-dimensional human characters.

[0004] This scheme does not need to draw each frame of action of the human character, but in order to ensure the smoothness of the human character animation, the producer needs to adjust the two-dimensional character skeleton at appropriate intervals to simulate the action posture of the two-dimensional character at each time point. If the interval time point is set too small, a large number of bone actions need to be adjusted, increasing the workload. If the interval time point is set too large, although IK inverse dynamics or interpolation methods can be used to correct the missing action state in the middle, the smoothness of the action will be poor. And the setting of the two-dimensional character skeleton action at each time point is very critical, which will directly affect the transition effect between the bone actions set at the two time points before and after. It can be seen that the above related methods still have problems such as complex action design and production, excessive workload, and low work efficiency in high-quality two-dimensional human character animation production.

DETAILED DESCRIPTION

[0026] In order to make the technical solutions in the present application or prior art clearer, the accompanying drawings needed in the embodiments or prior art description will be briefly introduced. Obviously, the accompanying drawings in the following description are only some embodiments of the present application, and all other embodiments obtained by a person of ordinary skill in the art without creative effort based on these accompanying drawings belong to the protection scope of the present application.

[0027] The present application provides a two-dimensional character animation production method and device based on somatosensory technology. The purpose is to reduce the production cycle of two-dimensional character animation, reduce repetitive animation parameter adjustment work, improve production efficiency and quality, and make such animation production method more flexible, and provide more details for two-dimensional character animation performance.

[0028] The application is described below Figures 1-7 The application provides a two-dimensional animation production method and device based on somatosensory technology. Figure 1 The application provides a two-dimensional animation production method based on somatosensory technology, as shown in Figure 1 The application provides a two-dimensional animation production method based on somatosensory technology, which comprises the following steps:

[0029] 101, divide the body of a two-dimensional character to be processed into a plurality of components, wherein the plurality of components comprise a head, a torso, a left hand, a right hand, a left leg, a right leg and other accessories.

[0030] Figure 2 The application provides a two-dimensional character body layering material schematic diagram, as shown in Figure 2 The two-dimensional character body is divided into a head layer, a torso layer, a left hand layer, a right hand layer, a left leg layer, a right leg layer and an other accessories layer. Each layer only contains a part of the body of the character, for example, the head layer only contains the head of the character. The layering can be performed by using an image processing software such as Photoshop.

[0031] 102, generate a skeleton and a skin of each component, set a weight relationship between the related skeletons, and determine a joint vertex of each component.

[0032] The two-dimensional character skeleton, skin and weight are produced: the two-dimensional character body layering material is imported into Unity, the skeleton, skin of the two-dimensional character are produced by using a Skinning Editor tool in Unity, and the weight relationship between the related skeletons is set, Figure 3 The application provides a two-dimensional character image with a two-dimensional skeleton, as shown in Figure 3

[0033] 103, obtain three-dimensional coordinate data of corresponding joint vertices of a real target character based on a somatosensory device, and map the three-dimensional coordinate data to the corresponding joint vertices of the two-dimensional character, so as to realize motion generation of the two-dimensional character.

[0034] In this step, human skeleton joint data is obtained and a two-dimensional character is bound. A somatosensory device (the somatosensory device is not limited to a Kinect 1 / 2, an Intel RealSense, an Xtion Pro or the like) is started. Skeleton joint coordinate data of an animator in a real world is captured, three-dimensional skeleton joint data is mapped to a two-dimensional plane, two-dimensional mapping coordinate data of the skeleton joint is obtained, and the converted two-dimensional joint is bound to the skeleton joint of the corresponding part of the two-dimensional character produced in step 102.

[0035] ​104. generating a two-dimensional animation according to a mapping relationship between the joint vertices of the target person and the joint vertices of the two-dimensional person.

[0036] The coordinates of the joint vertices of the target person are mapped to the joint vertices of the two-dimensional person to obtain the coordinates of the two-dimensional person, and the motion images of the plurality of two-dimensional characters are generated.

[0037] The corresponding two-dimensional character animation bitmap is found, the display frame rate is set, the image set on the bitmap file is called and read in sequence, and the images are displayed on the corresponding UI element to realize the motion animation playing of the corresponding two-dimensional character.

[0038] The two-dimensional animation production method based on the somatosensory technology can reduce the production complexity of the motion animation of the two-dimensional person character, reduce the workload of the animation producer, shorten the production period, and has a very smooth motion effect.

[0039] In one embodiment, the mapping of the three-dimensional coordinate data to the corresponding joint vertices of the two-dimensional person includes: projecting the three-dimensional coordinate data of the joint vertices of the first type of component to a two-dimensional plane to determine two-dimensional plane coordinates, and binding the joint vertices of the first type of component of the two-dimensional person head according to the two-dimensional plane coordinates; calculating the rotation angle between the joint vertices of the second type of component according to the three-dimensional coordinate data of the joint vertices of the second type of component, and binding the joint vertices of the second type of component of the two-dimensional person with the rotation angle; wherein the first type of component includes the head, the torso, and the components with a displacement less than a preset condition relative to the head and the torso, and the second type of component is other components except the first type of component.

[0040] Considering that the current method needs to use inverse kinematics technology to realize the two-dimensional skeleton binding effect, the embodiment of the present application proposes a two-dimensional person character skeleton binding and data driving method with universality, which can reduce the computational amount and realize better two-dimensional skeleton binding effect without using inverse kinematics technology.

[0041] Specifically, the method for mapping the three-dimensional skeleton joint data to a two-dimensional plane is different from the method of directly projecting the three-dimensional skeleton to a two-dimensional plane. The specific method is as follows:

[0042] (1) Head, torso and other parts relative to the limbs will not produce a large displacement, so you can directly head, torso and other components (first type of components) joint three-dimensional data directly projected onto a two-dimensional plane, take its plane coordinate data can be used to assign coordinates.

[0043] (2) For displacement relative to the first type of components, such as hands, feet and other components, such as hands, wrists, knees, ankles and other joints, such as joint vertices, then only calculate the rotation angle between the vertices of each joint, not to calculate the plane coordinates of the projection. Bind the limbs of the two-dimensional figure using angle assignment, so you do not need to use inverse kinematics to back-propagate, avoiding the situation of incoordinated animation figures.

[0044] In one embodiment, the setting of the weight relationship between the bones includes: determining all candidate bones affecting each component; adjusting the weight value of each candidate bone of each component to make the activity range of each component consistent with the real person.

[0050] After the skinning is completed, the bone weight needs to be modified to achieve a better skinning effect. First, select the torso, limbs, head and related torso parts and other accessory components of the two-dimensional figure. Determine which bones affect the currently selected two-dimensional figure body part.

[0046] Then, respectively select the key vertices on the head, torso, limbs and other parts of the two-dimensional figure body, view the bones and their weight values that can directly affect the skinning effect, and appropriately adjust the weight values of the bones (increase or decrease, increasing the weight of a bone will reduce the weight of other bones affecting the vertex, so that the total weight is 100%. Reducing the weight of a bone will increase the weight of other bones affecting the vertex, so that the total weight is 100%). Adjust the weight values of the bones to control the vertices of each part of the two-dimensional figure body, thereby adjusting and further optimizing the skinning effect.

[0047] In one embodiment, before adjusting the weight value of each candidate bone of each component, it further includes: removing the non-directly associated bones of each component from the candidate bones.

[0048] When setting the bone weight relationship of the two-dimensional figure, the non-directly associated bones on each part of the two-dimensional figure body need to be removed first (function: correct the wrong skinning and optimize the performance of the skinning. This step is not necessary to complete, and the effect is checked and corrected. If the skinning effect is good, this step can be skipped).

[0049] Specifically, after determining which bones affect the currently selected 2D character body part in the above embodiments, it is judged whether the skinning effect of each part of the character body is feasible. If the effect is not good, non-directly related bones are deleted. For example, the bones of the character's hair cannot affect the head, and the bones of the head cannot affect the torso. The skinning effect of each part of the body is adjusted to an acceptable range.

[0050] In one embodiment, generating a two-dimensional animation based on the mapping relationship between the joint vertices of the target character and the joint vertices of the two-dimensional character includes: driving the two-dimensional character to move based on the target character according to the mapping relationship between the joint vertices of the target character and the joint vertices of the two-dimensional character, and extracting each frame image of the two-dimensional character; generating a two-dimensional animation based on each frame image of the two-dimensional character; wherein each frame image is extracted continuously according to a preset time interval, or extracted according to the target character making different specific actions each time.

[0051] Figure 4 This is a schematic diagram of the manufacturing scenario provided by the present invention, such as... Figure 4 As shown, the animators set the frame animation image acquisition method (continuous or fixed format). Continuous frame animation image acquisition records a 2D character action image at a set time interval (e.g., 0.3 seconds); fixed format frame animation image acquisition does not consider time, and the animators determine the required action images in a "posed" manner. After setting the frame animation acquisition method on the computer host 2 with display segment device 8, the animators, as the target character 3, can perform continuous specific actions or pose in front of the motion sensing device 1. The 2D character 5 with skeletons will also be mapped to the corresponding action pose, thereby obtaining the extracted frame animation images 6. Finally, the system automatically encodes and saves the images into memory, resulting in an atlas file 7 composed of a sequence of frame animation images.

[0052] Apply in conjunction with the above embodiments, Figure 5 This is the second flowchart illustrating the two-dimensional animation production method based on motion sensing technology provided by this invention. It can be seen that the method of this embodiment eliminates the need for manual skeletal animation creation or frame-by-frame drawing of two-dimensional images, significantly differing from traditional software-based methods and offering higher efficiency. Based on parametric control, dynamic animation production can be performed in both continuous and fixed-format modes.

Figure 6 As shown, the 2D animation production device based on motion sensing technology includes: a splitting module 601, a setting module 602, a mapping module 603, and a generation module 604. The splitting module 601 divides the body of the 2D character into multiple parts, including a head, torso, left hand, right hand, left leg, right leg, and other attachments. The setting module 602 generates the skeleton and skin for each part, sets the weight relationships between related bones, and determines the joint vertices of each part. The mapping module 603 acquires the 3D coordinate data of the corresponding joint vertices of the real target character based on the motion sensing device and maps the 3D coordinate data to the corresponding joint vertices of the 2D character. The generation module 604 generates a 2D animation based on the mapping relationship between the corresponding joint vertices of the target character and the joint vertices of the 2D character.
