Data migration method and device, electronic equipment and readable storage medium

Abstract

The invention provides a data migration method and device, electronic equipment and a readable storage medium. The method comprises the following steps: obtaining the first vector, pointing to a target node, of a first reference point according to the position coordinates of the reference point in a first model, taking the sum of the projection lengths of the vectors of the first model on the first vector as the first parameter, taking the sum of the projection lengths of the vectors of the second model on the first vector as a second parameter, performing normalization processing on the first vector by using the first parameter to obtain a normalized first vector, inversely normalizing the normalized first vector to the second model by using the second parameter to obtain a pointing vector of the first reference point, and according to the pointing displacement coordinate of the first reference point, determining a migration position coordinate obtained after the position coordinate of the target node is migrated to the corresponding target node. The action presented by the second model according to the virtual object driven by the migration position coordinates can be close to the action of the entity, namely, high accuracy is achieved.

Description

technical field [0001] The present application relates to the field of electronic information, in particular to a data migration method and device, electronic equipment, and a readable storage medium. Background technique [0002] The production of 3D virtual objects (usually including characters and animals) is widely used in scenes such as animation production and movie special effects. Taking a 3D virtual character as an example of a 3D virtual object, the general process of making a 3D virtual character is as follows: capture various actions of entities such as actors through motion capture technology, generate data indicating these actions, and then distribute the data to designated 3D on the model. [0003] In practice, the ratio of each part of the model used to carry data may be different from the ratio of each part of the actual motion capture entity. Taking 3D virtual characters as an example: the 3D model used to carry data is different from the proportion of the...

Problems solved by technology

[0003] In practice, the ratio of each part of the model used to carry data may be different from the ratio of each part of the actual motion capture entity. Taking 3D virtual characters as an example: the 3D model used to carry data is different from the proportion of the actor's body , therefore, the produced virtual objects may have problems with inaccurate movements, for example, the "molding" caused by the difference between the body ratio of the 3D model and the body ratio of the actor
