Description

Image data processing method, system and storage medium

Technical Field

The application belongs to the technical field of digital printing, and particularly relates to an image data processing method, system and storage medium for generating a production drawing.

Background

The customized commodity is a physical commodity which is finally generated to contain information materials (such as patterns, characters, marks, accessories, sizes and the like) of personalized requirements specified by a user through modes of production, processing, cutting, making and the like and is different from standardized and large-scale production. The design area of the traditional customized commodity is mostly in a regular square shape, such as clothes, a mouse pad, a mug and the like, and when a production drawing required in printing is generated, the design area and an actual production area are mapped one to obtain the production drawing. However, as the demand of users for designing customized commodities increases, the design area of the rules cannot meet the demand, and the whole-width customization of commodities becomes a trend of current user demands. The full-width commodity refers to a design area of the whole commodity without distinguishing faces, the design elements can completely cover the whole commodity, and the patterns can be continuous. The whole commodity does not limit the customized area of the user any more, so that the commodity is more personalized.

However, when the design drawing of the whole commodity is converted into the production drawing, the irregular area cutting pieces are needed to be spliced manually by experience, so that whether the cutting area is needed by a user or not cannot be guaranteed, and the problems of missing of design elements, dislocation and the like can occur; during production, manual matching is needed, labor is consumed, and a production object often has large deviation with an effect graph.

Disclosure of Invention

Aiming at the problems of poor expansibility of full-width customized commodities, complex process from design to production, high labor cost, poor finished product effect and the like in the prior art, the invention provides an image data processing method in a first aspect, which comprises the following steps:

s1, setting a printing path diagram according to a design surface of a commodity, and defining an irregular shape to generate the printing path diagram through an SVG path;

and S2, filling design elements on the basis of the printing path diagram to generate a production diagram.

The scheme realizes the mapping of the design elements or the design drawing and the production drawing by self-defining the printing path drawing, directly generates the picture blocks required by target production and reduces the risk of manual cutting.

Further, the S2 design element is obtained by the coordinate conversion of the design surface and the printing path, and the conversion formula comprises:

zoom＝x1/(x/max(cx,cy)×cx1)

offset_x＝(x1/cx1×offset_cx-offset_x)/x

offset_y＝(y1/cy1×offset_cy-offset_y)/x

where zoom is a scaling ratio, offset _ x represents an x-axis direction offset amount, and offset _ y represents a y-axis direction offset amount. Using the coordinate transformation described above, it is ensured that the design elements are positioned consistently within the design surface and the print path.

Preferably, the items are grouped based on size, and items in a larger group reuse the printed path maps of items in a smaller group to avoid duplicate generation of the printed path maps.

Preferably, the production drawing conversion DPI is arranged for production drawing amplification to ensure the quality of the production drawing.

And further, generating an effect diagram by combining the design elements and the design drawing, and presenting the effect diagram formed by combining the design drawing and the commodity to a user.

Preferably, the effect map comprises a 2D effect map, the 2D effect map being formed by placing the design element on the design surface.

Preferably, the effect map comprises a pseudo 3D effect map, the pseudo 3D effect map being formed by placing the design elements on the design surface and matching the edge design points.

Preferably, the effect map comprises a 3D effect map, the 3D effect map being formed by placing the design element on a model, the model being generated by matching the print path map with a UV map associated with the model.

A second aspect of the present invention provides a production drawing generation system, which includes:

the printing path diagram generating module is configured for setting a printing path diagram according to the design surface of the commodity;

and the production diagram generating module is used for filling the design diagram on the basis of the printing path diagram to generate the production diagram.
