Abstract

The invention relates to a curved surface template segmentation method, a curved surface template segmentation device, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-segmented curved surface and a target segmentation unit size; extracting a first direction length and a second direction length of the target segmentation unit in the two curved surface directions from the target segmentation unit size; extracting a first structure line from the to-be-segmented curved surface according to the first direction length, determining a first segmentation point in the first structure line according to the second direction length, and generating a first isoparametric curve according to the first segmentation point; extracting a second structure line from the to-be-segmented curved surface according to the second direction length, determining a second segmentation point in the second structure line according to the first direction length, and generatinga second isoparametric curve according to the second segmentation point; and generating a segmentation line of the to-be-segmented curved surface according to the first isoparametric curve and the second isoparametric curve, obtaining a three-dimensional template segmentation model according to the segmentation line, and outputting the three-dimensional template segmentation model. By adopting the method. The working precision of curved surface template segmentation can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a curved surface template segmentation method, device, computer equipment and storage medium. Background technique [0002] Fair-faced concrete is a commonly used expression method in modernist architecture. As a way to use the original natural texture of concrete to reflect the texture of the building, it is poured once and does not require post-modification. The joints and holes of the formwork during the construction process , Lines, decorative patterns and various construction traces are rubbed on the concrete surface. Therefore, the fair-faced concrete formwork puts forward extremely high requirements for formwork selection, formwork division, and panel division and arrangement. [0003] When modeling and designing concrete formwork, the formwork deepening work of fair-faced concrete is still carried out in the traditional two-dimensional drawing software repres...

Problems solved by technology

[0003] When modeling and designing concrete formwork, the formwork deepening of fair-faced concrete is still carried out in the traditional two-dimensional drawing software represented by AutoCAD. Most of the process uses CAD to manually arrange and divide the formwork. However, since the surface of concrete buildings is often a curved shape, if only two-dimensional drawing software is used, the simple two-dimensional space projection cannot accurately locate the shape of the curved surface, and thus cannot Accurately segment the template according to the design plan
