Embodiment 1

[0031] figure 1 A flowchart showing a method for generating a texture map according to an embodiment of the present invention, such as figure 1 As shown, the method may include the following steps:

[0032] S101: Obtain structural information of the unit structure of the preform to be prepared. Here, the structure information includes the number of warp yarn rows, the number of warp yarn layers, the number of weft yarn rows, the number of weft yarn layers and the positional relationship between warp yarns and weft yarns of the preform unit structure to be prepared.

[0033] In this embodiment, the unit structure of the preform to be prepared is a three-dimensional woven structure. Therefore, the unit structure of the preform to be prepared not only includes multiple columns and multiple layers of warp yarns, but also includes multiple columns and multiple layers of weft yarns. Specifically, Figure 2A and Figure 2B Shown is a three-dimensional woven structure comprising 2 ...

Abstract

The invention discloses a textured pattern generation method and a device, electronic equipment and a readable storage medium. The method comprises the steps of acquiring structure information of a to-be-prepared prefabricated body unit structure; wherein the structure information comprises the number of columns of warp yarns, the number of layers of warp yarns, the number of columns of weft yarns, the number of layers of weft yarns and the positional relationship between the warp yarns and the weft yarns; obtaining the row and column number of the to-be-generated textured pattern according tothe structure information, and obtaining the corresponding relation between each pixel point in the to-be-generated textured pattern and the weft yarns and the warp yarns in the to-be-prepared prefabricated body unit structure; obtaining the pixel value of each pixel point according to the corresponding relation and the position relation between the warp yarns and the weft yarns, and generating ato-be-generated texture pattern; wherein the pixel value comprises a first pixel value and a second pixel value, when the warp yarn corresponding to the pixel point is located above the correspondingweft yarn, the pixel value of the pixel point is the first pixel value, and otherwise, the pixel value of the pixel point is the second pixel value. By implementing the method, the texture pattern ofthe unit structure of the to-be-prepared prefabricated body can be automatically generated.

Description

technical field [0001] The present invention relates to the field of manufacturing technology, in particular to a texture pattern generation method, device, electronic equipment and readable storage medium. Background technique [0002] As a composite reinforced structure, 3D woven prefabricated body is more and more widely used in aviation, aerospace, construction, automobile and other fields. Since most of the process of manufacturing three-dimensional prefabricated bodies using traditional second-generation looms requires manual participation, and because the control of the opening is controlled by lifting and lowering the heald frames, when the organizational structure is different, the number of heald frames required is also different, especially For the manufacture of complex structures, multiple heald frames are required to complete, that is to say, the efficiency of manufacturing three-dimensional woven preforms with traditional second-generation looms is low, and th...
