Description

Technical Field

[0001] This invention relates to the field of data processing, and more particularly to a method, apparatus, device, and storage medium for adjusting lens attributes. Background Technology

[0002] In the development of games such as SRPGs and JRPGs, numerous simple event animations are required to advance the game's plot and enhance the gaming experience. These event animations are relatively simple in content, quick to produce, and not particularly difficult to create, with no strong customization requirements. They primarily consist of static dialogue animations of characters, accompanied by looping actions.

[0003] Because of the large production volume and relatively low difficulty, involving the piecing together and combining of numerous resources, and because such animations are mostly handled by planners—that is, non-professional film and television production personnel—the existing camera motion library can be immediately accessed after the character positioning in the scene is completed. This allows for verification of the visual effects, iteration, and output. However, the positions of the characters in each animation's scene differ from their positions when the camera motion library was created, necessitating adjustments to the existing camera motion library to match the new animation. Summary of the Invention

[0004] The main objective of this invention is to solve the technical problem that existing camera motion libraries cannot be applied due to the different positions of scenes and characters in the prior art.

[0005] The first aspect of this invention provides a lens attribute adjustment method, the method comprising:

[0006] In response to the current viewpoint camera position adjustment operation, the current viewpoint camera is bound to the camera of each camera motion pose in the camera motion library in the target frame, and the corresponding motion node is generated.

[0007] Construct the parent-child node relationship between each of the aforementioned mobile nodes and the camera in the target frame for each lens motion pose in the lens motion library;

[0008] Calculate the transformation data of each moving node after the current viewpoint camera is adjusted;

[0009] Based on the parent-child node relationship and the transformation data of each of the moving nodes, the position information of the camera in the target frame for each lens motion pose in the lens motion library after the current viewpoint lens adjustment is determined.

[0010] A second aspect of the present invention provides a lens property adjustment device, comprising:

[0013] The calculation module is used to calculate the transformation data of each moving node after the current viewpoint camera is adjusted;

[0014] The position determination module is used to determine the position information of the camera in the target frame of each lens motion pose in the lens motion library after the current viewpoint lens adjustment, based on the parent-child node relationship and the transformation data of each of the moving nodes.

[0015] A third aspect of the present invention provides a lens attribute adjustment device, comprising: a memory and at least one processor, wherein the memory stores instructions, and the memory and the at least one processor are interconnected via a circuit; the at least one processor invokes the instructions in the memory to cause the lens attribute adjustment device to perform the steps of the lens attribute adjustment method described above.

[0016] A fourth aspect of the present invention provides a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform the steps of the lens attribute adjustment method described above.

[0017] This invention, in response to a current viewpoint lens position adjustment operation, binds the current viewpoint lens to cameras in the target frame corresponding to each lens motion pose in the lens motion library, generating corresponding motion nodes; constructs parent-child node relationships between each motion node and cameras in the target frame corresponding to each lens motion pose in the lens motion library; calculates the transformation data of each motion node after the current viewpoint lens adjustment; and determines the position information of cameras in the target frame corresponding to each lens motion pose in the lens motion library after the current viewpoint lens adjustment based on the parent-child node relationships and the transformation data of each motion node. This invention provides a method for inversely determining the camera position in a specified frame of the lens motion library based on the current viewpoint lens position. By binding the viewpoint lens to a specified frame of a camera in the lens motion library to generate motion nodes, and by constructing parent-child node relationships, when the current viewpoint lens is adjusted, the bound motion nodes move, thereby causing the specified frame of the camera in the lens motion library to move through the parent-child node relationships, determining the camera position in the specified frame, and achieving the corresponding lens effect in the lens motion library.

[0026] This invention provides a lens attribute adjustment method, apparatus, device, and storage medium. In response to a current viewpoint lens position adjustment operation, the current viewpoint lens is bound to cameras in the target frame corresponding to each lens motion pose in the lens motion library, generating corresponding motion nodes. A parent-child node relationship is constructed between each motion node and the cameras in the target frame corresponding to each lens motion pose in the lens motion library. The transformation data of each motion node after the current viewpoint lens adjustment is calculated. Based on the parent-child node relationship and the transformation data of each motion node, the position information of the cameras in the target frame corresponding to each lens motion pose in the lens motion library after the current viewpoint lens adjustment is determined. This invention also provides a method for inversely determining the camera position in a specified frame of the lens motion library based on the current viewpoint lens position. By binding the viewpoint lens to a specified frame of a camera in the lens motion library, generating motion nodes, and constructing parent-child node relationships, when the current viewpoint lens is adjusted, the bound motion nodes move, thereby causing the specified frame of the camera in the lens motion library to move, determining the camera position in the specified frame, and achieving the corresponding lens effect in the lens motion library.

[0027] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the lens attribute adjustment method in this invention includes:

[0029] 101. In response to the position adjustment operation of the current viewpoint camera, bind the current viewpoint camera to the camera of each camera motion pose in the camera motion library in the target frame, and generate the corresponding motion node.

[0030] In this embodiment, the current viewpoint is the camera angle presented by the software when the user uses DCC (Digital Content Creation) software, including Maya, Houdini, Nuke, Unreal Engine, etc. The user can adjust the position of the current viewpoint in various ways, such as using a trackball to control the direction of the 3D view. The viewpoint can be changed by clicking and dragging on the trackball, or by creating and setting up cameras in DCC software, allowing the user to observe the scene from any position. In the main view window, select the "Camera" or "Camera" option, and then create a new camera. Camera parameters such as position, rotation, and lens focal length can be adjusted. This embodiment does not limit the customization of the viewpoint position for adjusting the current viewpoint position. When a change in viewpoint position occurs, the subsequent steps of this method are performed. In this embodiment, the camera motion library refers to a software library or toolset used to store and manage various camera motion effects, including translation, rotation, scaling, shaking, and other dynamic effects.

[0031] In practical applications, the camera pairs corresponding to the various camera motion effects in the camera motion library are implemented in different poses such as movement, rotation, scaling, and shaking in different frames. By connecting the effects captured by the cameras in different frames, the camera motion effect can be achieved. In this embodiment, the user specifies the number of frames for the cameras in the camera motion library in advance. The specified number of frames is the target frame. The current viewpoint camera and the camera of each camera motion pose in the camera motion library at the target frame are bound together. A movement node related to the position of the current viewpoint camera and the position of the camera of each camera motion pose in the camera motion library at the target frame is generated. This movement node is the Transform node, which is the most basic node in DCC software. It provides Translate, Rotate, and Scale attributes, representing the position information of a point in the three-dimensional world.

[0032] 102. Construct the parent-child node relationship between each moving node and each camera in the camera motion library at the target frame;

[0033] In practical applications, the DCC software used contains multi-level tree nodes. A multi-level tree node refers to a hierarchical structure in which each node can have multiple child nodes, and each child node can also have its own child nodes, and so on. In the world coordinate system, the child node will completely inherit the transformation of the parent node. Therefore, in this embodiment of the invention, as long as the child node is matched, the position of the parent object can be calculated by using the inverse matrix of the child object, achieving the effect of matching the position of the specified object while maintaining the relative motion of the child object. In this embodiment of the invention, the generated moving node is automatically identified and selected as the parent node, and the camera in the lens motion library is selected as the child node. Then, the connection tool is used to connect the selected child-child nodes with the parent node to build the parent-child node relationship.

[0034] 103. Calculate the transformation data of each moving node after the current viewpoint camera is adjusted;

[0035] In this embodiment, since the conversion data of the moving node is related to the position of the current viewpoint camera, the conversion data of the moving node will also change when the position of the current viewpoint camera changes. Therefore, the conversion data of the moving node after the current viewpoint camera is adjusted can be recalculated according to the moving node generation process in the above steps.

[0036] 104. Based on the parent-child node relationship and the transformation data of each moving node, determine the position information of the camera in the target frame for each lens motion pose in the lens motion library after the current viewpoint lens adjustment.

[0037] In practical applications, in DCC software, child nodes inherit the Transform data of their parent nodes. This inheritance is achieved through a hierarchical structure. Each node has a transform attribute that describes its position, rotation, and scaling. When a node is a child node of another node, it automatically inherits the transform attribute of its parent node. Therefore, in this embodiment, through the parent-child constraints between parent and child nodes, the cameras in each lens pose in the lens motion library inherit the transformation data of each moving node after the current viewpoint lens adjustment, thereby moving the cameras in each lens pose in the head motion library to the corresponding positions and determining the position information of those positions.

[0038] In this embodiment, in response to the current viewpoint lens position adjustment operation, the current viewpoint lens is bound to the cameras in the target frame corresponding to the lens motion poses in the lens motion library, generating corresponding motion nodes; a parent-child node relationship is constructed between each motion node and the cameras in the target frame corresponding to the lens motion poses in the lens motion library; the transformation data of each motion node after the current viewpoint lens adjustment is calculated; based on the parent-child node relationship and the transformation data of each motion node, the position information of the cameras in the target frame corresponding to the lens motion poses in the lens motion library after the current viewpoint lens adjustment is determined. This invention provides a method for inversely determining the camera position in a specified frame of the lens motion library based on the current viewpoint lens position. By binding the viewpoint lens to a specified frame of the camera in the lens motion library to generate motion nodes, and by constructing parent-child node relationships, when the current viewpoint lens is adjusted, the bound motion nodes move, thereby causing the specified frame of the camera in the lens motion library to move through the parent-child node relationship, determining the camera position in the specified frame, and realizing the corresponding lens effect in the lens motion library.

[0039] Please see Figure 2 Another embodiment of the lens attribute adjustment method in this invention includes:

[0040] 201. In response to the current viewpoint lens position adjustment operation, perform matrix operation on the first transformation data of the camera in the target frame for each lens motion pose to generate the corresponding first transformation matrix;

[0041] In this embodiment, the first transformation data includes one or more of the camera position value, rotation value, or scaling value of each lens motion pose in the target frame; the step of performing matrix operations on the first transformation data of each lens motion pose in the target frame in response to the current viewpoint lens position adjustment operation to generate the corresponding first transformation matrix includes: in response to the current viewpoint lens position adjustment operation, generating matrices corresponding to the position value, rotation value, and scaling value in the first transformation data according to a preset matrix generation algorithm, respectively obtaining a position matrix, a rotation matrix, and a scaling matrix; multiplying the position matrix, rotation matrix, and scaling matrix to obtain the first transformation matrix corresponding to the first transformation data.

[0042] Specifically, the camera in the lens motion library is called CamOri, and the current viewpoint lens is called CamDes. When adjusting the position of the current viewpoint lens, CamDes obtains the position value L1 and rotation value R1 of CamOri in world coordinates at the input frame number T, which is the target frame. It creates a matrix Matrix1, which is the first transformation matrix, by generating the translation matrix, rotation matrix, and scaling matrix corresponding to the position value L1, rotation value R1, and scaling value Scale, Scale, Scale vectors. Then, it multiplies these three matrices to form the final transformation matrix, which is the first transformation matrix.

[0043] 202. Multiply the inverse of the first transformation matrix by the position and rotation values ​​of the origin in world coordinates to obtain the second transformation data;

[0044] In this embodiment, the inverse matrix InvMatrix1 of the first transformation matrix Matrix1 is multiplied by the origin coordinates L0 (0, 0, 0) to obtain the new world coordinate value L2. This is equivalent to moving the current camera Cam1 from L1 to L0, which requires the parent object to move from L0 to L2. Furthermore, the inverse matrix InvMatrix1 of the first transformation matrix Matrix1 is multiplied by the origin coordinates R0 (0, 0, 0) to obtain the new world coordinate rotation value R2. This is equivalent to rotating the current camera Cam1 from R1 to R0, which requires the parent object to rotate from R0 to R2. The resulting new world coordinate values ​​L2 and R2 constitute the second transformation data.

[0045] 203. Generate the corresponding fourth transformation data based on the binding algorithm, each second transformation data, and the third transformation data of the current viewpoint camera;

[0046] In this embodiment, generating corresponding fourth transformation data based on the second transformation data and the third transformation data of the current viewpoint lens includes: performing matrix operations on each third transformation data to generate a second transformation matrix corresponding to each third transformation data; multiplying each second transformation matrix with the second transformation data to obtain a corresponding multiplication result; calculating the scaling value of each moving node based on the scaling value of the camera in the target frame of the lens motion pose in the first transformation data; and generating corresponding fourth transformation data based on each multiplication result and the scaling value of each moving node.

[0047] Specifically, the position value LD and rotation value RD of the current viewpoint camera CamDes in world coordinates are obtained. Through a similar generation process as the first transformation matrix, a matrix Matrix2, which is the second transformation matrix, is created by multiplying the L2 position value in the second transformation data by the second transformation matrix Matrix2. The new world coordinate value L3 is obtained by multiplying the L2 rotation value in the second transformation data by the second transformation matrix Matrix2. The new world rotation value R3 is obtained by multiplying the L2 rotation value in the second transformation data by the second transformation matrix Matrix2. Based on the camera's scaling value Scale,Scale,Scale vector in the target frame of the first transformation data, a vector with a scaling value of 1 / Scale is calculated.

[0048] 204. Create motion nodes for each camera motion pose in the camera motion library, and use the fourth transformation data as the transformation data for the corresponding motion node;

[0049] In this embodiment, a new mobile node is created by transforming a vector with a scaling value of 1 / Scale. The new world coordinate value L3 and the new world rotation value R3 are the position and rotation values ​​of the mobile node, respectively, thus obtaining the new mobile node.

[0050] 205. Construct the parent-child node relationship between each moving node and each camera in the camera motion library in the target frame;

[0051] 206. Calculate the transformation data of each moving node after the current viewpoint camera is adjusted;

[0052] 207. Based on the parent-child node relationship and the transformation data of each moving node, determine the position information of the camera in the target frame for each lens motion pose in the lens motion library after the current viewpoint lens adjustment.

[0053] In this embodiment, steps 205-207 are similar to steps 102-104 in the previous embodiment, and will not be described again here.

[0054] In this embodiment, in response to the current viewpoint lens position adjustment operation, the current viewpoint lens is bound to the cameras in the target frame corresponding to the lens motion poses in the lens motion library, generating corresponding motion nodes; a parent-child node relationship is constructed between each motion node and the cameras in the target frame corresponding to the lens motion poses in the lens motion library; the transformation data of each motion node after the current viewpoint lens adjustment is calculated; based on the parent-child node relationship and the transformation data of each motion node, the position information of the cameras in the target frame corresponding to the lens motion poses in the lens motion library after the current viewpoint lens adjustment is determined. This invention provides a method for inversely determining the camera position in a specified frame of the lens motion library based on the current viewpoint lens position. By binding the viewpoint lens to a specified frame of the camera in the lens motion library to generate motion nodes, and by constructing parent-child node relationships, when the current viewpoint lens is adjusted, the bound motion nodes move, thereby causing the specified frame of the camera in the lens motion library to move through the parent-child node relationship, determining the camera position in the specified frame, and realizing the corresponding lens effect in the lens motion library.

[0055] Please see Figure 3 Another embodiment of the lens attribute adjustment method in this invention includes:

[0056] 301. In response to the position adjustment operation of the current viewpoint camera, bind the current viewpoint camera to the camera of each camera motion pose in the camera motion library in the target frame, and generate the corresponding motion node.

[0057] 302. Construct the parent-child node relationship between each moving node and each camera in the camera motion library at the target frame;

[0058] 303. Calculate the transformation data of each moving node after the current viewpoint camera is adjusted;

[0059] In this embodiment, steps 301-303 are similar to steps 101-103 in the first embodiment, and will not be described again here.

[0060] 304. Based on the parent-child node relationship, the transformation data of each moving node is inherited to the camera in the target frame corresponding to the lens motion pose in the lens motion library, so that the camera in the target frame with each lens motion pose can adjust its position and determine the position information of the camera in the target frame with each lens motion pose.

[0061] In this embodiment, a parent-child constraint is formed by establishing a parent-child node relationship between the constructed motion node and each camera motion pose in the camera of the target frame. This parent-child constraint is a tool used to control the parent-child node relationship. For example, in animation, the movement of a child object can be restricted to its parent object, preventing it from being affected by other factors. The parent-child constraint allows one object to move or rotate relative to another object without losing their parent-child node relationship. In this embodiment, the offset of the motion node after adjustment at the current camera viewpoint position can be calculated. Through the parent-child node relationship, this offset is inherited by the child object. The child object calculates its position based on the offset of its parent object. The calculation relationship for the translation amount is as follows:

[0062] P_sub = P_parent + P_relative

[0063] Where P_sub is the position of the child object, P_parent is the position of the parent object, and P_relative is the offset of the child object in the coordinate system of the parent object.

[0064] The calculation relationship for the rotation amount is as follows:

[0065] R_sub_world=R_parent_world+R_relative_parent

[0066] Where R_sub_world is the rotation of the child object, R_parent_world is the rotation of the parent object, and R_relative_parent is the rotation offset of the child object in the parent object's coordinate system.

[0067] The scaling factor is calculated as follows:

[0068] S_sub = S_parent * S_relative

[0069] Here, S_sub is the scaling of the child object, S_parent is the scaling of the parent object, and S_relative is the scaling offset of the child object in the parent object's coordinate system. Based on these calculations, the position information of the child object, i.e., the camera's position in the target frame, for each lens's motion pose, can be calculated.

[0070] 305. Obtain the relative positional relationship between the camera in the target frame and other frames other than the target frame for each camera motion pose in the camera motion library;

[0071] It should be noted that the relative position, rotation, and scaling relationships of the camera in each lens motion pose in the lens motion library are determined at any given frame. When needed, this information can be directly retrieved from the pre-stored storage location. In this embodiment, the given frame is the target frame.

[0072] 306. Based on the relative positional relationships and the position information of the camera in the corresponding camera motion pose in the lens motion library in the target frame, calculate the position information of the camera in the lens motion pose in the lens motion library after the current viewpoint lens is adjusted, except for the target frame.

[0073] In this embodiment, when the position information of a specified frame is determined, the position information of the frames before and after the specified frame can be calculated based on the relative position relationship, rotation relationship, scaling relationship, etc. between the specified frame and the frames before and after the specified frame. The frames before and after the specified frame are then used as specified frames for calculation again. By iterating in a loop, the position information of the camera in all frames of the lens motion pose can be calculated.

[0074] 307. Based on the position information of the camera in all frames after the current viewpoint lens is adjusted, realize the motion effect of the camera in the current viewpoint lens after the current viewpoint lens is adjusted.

[0075] In this embodiment, by adjusting the position information of the camera in all frames after adjusting the motion pose of each lens using the front-view lens, and then moving the lens again to take pictures, the lens motion effect of the camera after adjusting the motion pose of each lens using the current-view lens can be achieved.

[0076] In this embodiment, in response to the current viewpoint lens position adjustment operation, the current viewpoint lens is bound to the cameras in the target frame whose lens motion poses are in the lens motion library, generating corresponding motion nodes; a parent-child node relationship is constructed between each motion node and the cameras in the target frame whose lens motion poses are in the lens motion library; the transformation data of each motion node after the current viewpoint lens adjustment is calculated; and based on the parent-child node relationship and the transformation data of each motion node, the position information of the cameras in the target frame whose lens motion poses are in the lens motion library after the current viewpoint lens adjustment is determined. This invention provides a method for inversely determining the camera position in a specified frame of the lens motion library based on the current viewpoint lens position. By binding the viewpoint lens to a specified frame of the camera in the lens motion library, generating motion nodes, and constructing parent-child node relationships, when the current viewpoint lens is adjusted, the bound motion nodes move, thereby causing the specified frame of the camera in the lens motion library to move through the parent-child node relationship, determining the camera position in the specified frame, and realizing the corresponding lens effect in the lens motion library.

Furthermore, the processor 610 may be configured to communicate with the storage media 630 and execute a series of instruction operations in the storage media 630 on the lens attribute adjustment device 600 to achieve the following steps:

[0112] In response to the current viewpoint lens position adjustment operation, the current viewpoint lens is bound to the cameras in the target frame corresponding to the lens motion poses in the lens motion library, generating corresponding motion nodes; a parent-child node relationship is constructed between each motion node and the cameras in the target frame corresponding to the lens motion poses in the lens motion library; the transformation data of each motion node after the current viewpoint lens adjustment is calculated; based on the parent-child node relationship and the transformation data of each motion node, the position information of the cameras in the target frame corresponding to the lens motion poses in the lens motion library after the current viewpoint lens adjustment is determined. This invention provides a method for inversely determining the camera position in a specified frame of the lens motion library based on the current viewpoint lens position. By binding the viewpoint lens to a specified frame of the camera in the lens motion library to generate motion nodes, and by constructing parent-child node relationships, when the current viewpoint lens is adjusted, the bound motion nodes move, thereby causing the specified frame of the camera in the lens motion library to move through the parent-child node relationship, determining the camera position in the specified frame, and realizing the corresponding lens effect in the lens motion library.
