Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention and not to limit its scope.

Example 1

In an embodiment of the present invention, a method for instantly manufacturing a medal is disclosed, as shown in fig. 1, comprising the steps of:

s1, automatically identifying a selected picture to obtain a carving pattern and an initial carving depth; specifically, the engraved image is a specific scene in the selected picture, such as a portrait, an object image, and a scene image;

s2, receiving carving parameters input by a user, generating a carving scheme of a selected picture by combining the carving pattern and the initial carving depth, generating a picking code of the selected picture souvenir badge and pushing the picking code to the user; specifically, the engraving scheme includes engraving depth, width, engraving sequence, and the like;

s3, according to the sequence of the received codes, selecting matched souvenir badge blanks according to the carving scheme in a preset time period, and carrying out laser carving processing;

s4, judging whether the surface graph of the processed souvenir badge blank is consistent with the carved graph in the carving scheme, if not, adjusting the carving depth in the carving scheme until the processed souvenir badge blank is consistent with the graph of the carving scheme, and obtaining the processed souvenir badge;

and S5, taking out the processed souvenir medals from the tray according to the retrieval codes of the souvenir medals input by the user.

During implementation, the mobile terminals such as the mobile phone and the like can process pictures on line, the users can be intelligently assisted to select the pictures, the pictures can be selectively processed, characters are added, the sizes of the pictures are adjusted, and rapid picture processing is realized. Meanwhile, the engraving system only engraves the souvenir badge blank in a small range, can perform reverse calculation through a grey-scale image, removes redundant materials by utilizing laser, realizes a three-dimensional outline pattern customized by a user, does not need manual participation in the whole manufacturing process from ordering to commemorative badge taking, realizes a full-automatic flow, greatly improves the preparation efficiency, and improves the user experience; the pairing of the ordering code (processing sequence) and the memorial tablet code avoids the queuing production process in the scenic spot, saves the time for users to play the scenic spot, and can enable the memorial tablet with the memorial significance to be produced by themselves efficiently.

Compared with the method provided by the prior art CN110900635A, the method provided by this embodiment brings great convenience and good user experience to the user through the mode of "mobile phone online autonomous design-instant printing-scenic spot pickup". This laser sculpture memorial tablet has fused recreational and memorial meaning, has broken the unanimous traditional scenic spot souvenir mode of style, has added the autonomous design that the flexibility is stronger, increases individual participation and interest to, with user's individual creative idea and scenic spot culture antithetical couplet, have the memorial significance, be a brand-new memorial mode. The method can bear valuable stories, and can raise the emotion in a physical mode, thereby being beneficial to improving the tourism interest in the tourism process and spreading local culture.

Example 2

Optimization is performed on the basis of the method described in example 1, and step S1 is further refined as:

s11, receiving one or more pictures input by a user.

S12, identifying whether the resolution and the contrast of the picture meet preset requirements, if not, prompting a user to input the picture again, identifying again until the resolution and the contrast meet the preset requirements, and executing the next step; and selecting a picture with resolution and contrast meeting preset requirements from the pictures.

Illustratively, whether the image resolution is larger than 118.11 pixels/cm or not is automatically judged, if so, whether the contrast meets the preset requirement or not is continuously judged, if any one does not meet the preset requirement, the picture is deleted, and if so, the next step is executed. The purpose is to filter out the picture with poor recognition effect.

And S13, automatically identifying the carved patterns in the obtained picture, judging whether the carved target feature region is clear and sharp in outline, if so, pushing the carved target feature region to a user for the user to select the picture, otherwise, prompting the user to input the picture again, and pushing the picture to the user for selection after meeting the requirement.

Illustratively, if the engraved object is a portrait, it is determined whether or not the characteristic region (face, hand, trunk outline) is clear, and if the engraved object is a fruit tree, it is determined whether or not the characteristic region (leaf, fruit) is clear.

And after a picture with clear engraving target and sharp outline in the identification result is selected, zooming the engraving image in the picture to match the size of the commemorative medallion.
