Problems solved by technology

This method of manually designing construction drawings is inefficient, has high technical thresholds, and greatly increases the cost of creation
Some low-cost new painters are also unable to independently design 3D paintings due to lack of experience, which has become a pain point in the 3D painting industry

Embodiment Construction

[0095] Such as figure 1 Shown, a kind of perspective transform-based 3D drawing construction drawing automatic generation method of the present invention comprises the following steps:

[0096] Step 101, receiving the 3D painting image Src to be processed input by the user, the type of 3D painting selected by the user and required parameters.

[0097] This method requires the user to input the rendering of the 3D painting to be processed, select the corresponding type of 3D painting and the required parameters. Let the 3D painting effect image input by the user be marked as Src, and the optional 3D painting types include floor painting, wall floor painting, and corner painting; the range of the site that can be drawn is the length H and width W of the plane S in all directions; the best observation Distance d; best observation height b.

[0098] Step 102, calculating the three-dimensional coordinates (x, y, z) of the drawing site.

[0099] Such as Figure 2-6 As shown, th...

Abstract

The invention provides a 3D painting construction drawing automatic generation method based on perspective transformation. The method is suitable for various types of 3D painting art forms including ground paintings, wall ground paintings and wall corner paintings. The method comprises the steps that modeling of various types of 3D paintings is performed, perspective transformation is performed on the 3D painting models, an input 3D painting design sketch is cut, and a transformation matrix is obtained according to the model perspective projection result and drawing place information; and perspective transformation is performed on the cut 3D painting design sketch by using the transformation matrix, and finally a 3D painting construction drawing based on the place information is outputted. The method is convenient to use and can perform batch processing and automatic generation so that the industry pain point of long design period in the conventional colored drawing creation and construction can be alleviated, the less experienced painter is enabled to rapidly master the 3D painting design skills and thus the prosperity of the colored drawing making industry is facilitated.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for automatically generating construction drawings of 3D drawings based on perspective transformation. Background technique [0002] In recent years, naked-eye 3D paintings have received more and more attention and popularity due to their special artistic expression, super visual shock and interesting interaction, covering decoration, advertising, exhibitions, home furnishing and other fields. Has broad development prospects. 3D painting art can be divided into wall painting, floor painting, wall and floor painting, concave corner painting and so on. Among them, 3D ground painting uses the ground as the carrier of creation, and uses the principle of plane perspective to create a three-dimensional virtual three-dimensional effect on a two-dimensional plane. When drawing 3D ground paintings, it is necessary to follow the anti-perspective "near small, far large" optical il...
