Description

Novel line manuscript copying tool for painting works

Technical Field

The invention relates to the technical field related to painting tools, and discloses a novel line draft copying tool for a painting work. The tool can be used for conveniently copying the line draft of the painting to objects of different materials and shapes according to the required proportion, and quickly finishing the step of drafting the line draft when the painting is drawn again.

Background

First, in most cases, a color pictorial representation is completed by drawing a draft directly from the surface of the object to be drawn. However, when the same pair of paintings needs to be drawn again on other objects, the line draft needs to be drafted again on the surface of the object, and all the drawing processes need to be repeated. Secondly, for the painting of super large breadth, key factors such as structural relation, perspective proportion are all difficult to control, and to this problem, some traditional practices are that the work of small size is designed earlier, and then the method of drawing little check, and the copy of the work of small size that designs, check to the place that needs the work of drawing by a wide margin, and efficiency is very low.

If the line draft of the first painting work or the design draft can be copied to an object needing drawing after being zoomed according to a required proportion, repeated work of the part is avoided, the work efficiency is improved, and the driving capability of a painter on the large and super-large painting works is greatly improved by a method of splitting and splicing the large and super-large painting works.

Disclosure of Invention

The invention discloses a novel line draft copying tool for a painting work, which can effectively improve the working efficiency of the same painting work during repeated painting and effectively improve the ability of a painter for controlling large and overlarge width of the painting work.

The invention is realized by the following technical scheme:

step 1, firstly, the line manuscript picture or the finished picture of the target painting work is converted into a picture format which can be identified by a computer by using methods of photography, scanning, direct storage and the like, and if the picture is a raster picture file, the raster picture file is converted into a vector picture file by using common image processing software.

And 2, zooming and segmenting the vector picture file generated in the step 1 according to relevant settings by using special computer software of the invention, setting splicing positioning elements, extracting line path data one by one, segmenting the extracted path into polygons or circles with intervals according to the path data and the relevant settings, and storing the information of the coordinates, the sizes and the like of the polygons or the circles into corresponding machine language files according to a process route used in the next step.

And 3, using the machine language file stored in the step 2, and hollowing out the polygonal or circular shape set by the machine language file on the paper, plastic or leather serving as the base material by adopting corresponding knife carving, photoetching and etching process routes.

By this time, the new line copy tool is completed. When the line manuscript copying tool is used, the line manuscript copying tool is only required to be temporarily fixed on the surface of an object to be painted by using an adhesive tape or hand-sprayed adhesive, the surface of the line manuscript copying tool is painted or sprayed by using pigment, and the painted or sprayed pigment can pass through the hollowed-out part and is left at a corresponding position on the surface of the object due to the existence of the hollowed-out polygon or circle, so that the line manuscript content of a target painting work carried by the line manuscript copying tool is copied on the surface of the object to be painted after the line manuscript copying tool is taken out.

If the line manuscript of the target painting work is not wanted to be left on the object to be painted in a real color mode, a line manuscript copying tool can be placed between the projection lamp and the object to be painted, and the line manuscript of the target painting work can be displayed on the object to be painted in a light leakage mode (figure 3) under the conditions that the environment brightness and the projection lamp brightness are reasonable and the position of the line manuscript copying tool is correct, wherein the line manuscript copying tool is in a hollow polygon or circle shape. Furthermore, the distance among the projection lamp (4), the line manuscript copying tool (5) and the object to be painted can be adjusted, and the size of the shadow (6) formed by light leakage can be adjusted.

The line manuscript copying tool can be used for conveniently copying the line manuscript of the target painting work to clothes, cabinets, walls and floors, and has wide application.

The invention has the beneficial effects that: by using the line draft copying tool disclosed by the invention, the efficiency and the accuracy of line draft drawing can be effectively improved when the same drawing work is repeatedly drawn, the line draft can be more flexibly copied to the surfaces of objects of different materials and shapes, and for a plane object, the proportion of the line draft re-presented can be flexibly adjusted in a light projection manner.

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 1, step 1, a line manuscript or a finished drawing of a target pictorial representation is obtained by using a camera, a mobile phone, a scanner, an electronic product drawing direct storage mode and the like.

And 2, if the picture format acquired in the step 1 is not the vector picture format, converting the picture into the vector picture format by using conversion software which is usually used in life, and otherwise, skipping the step.

And 3, zooming the obtained vector picture file by using common image processing software according to requirements, determining how to split the vector picture file according to the size of the basic material, and performing related operations.

And 4, if the vector picture file is subjected to segmentation operation in the step 3, setting a positioning element at a corresponding position, otherwise, skipping the step.

And 5, acquiring path data of all lines in the vector picture file by using the special computer software, wherein the path data specifically comprises a coordinate value (Xs, ys) of a starting point, a vector angle value (degree) of the starting point, a vector length value (Lsa) of the starting point, a coordinate value (Xe, ye) of an end point, a vector angle value (degree) of the end point and a vector length value (Lea) of the end point.

And 6, dividing the path into polygons or circles with intervals. Specifically, a long side dimension (C) and a narrow side dimension (D) of a polygon or a circle and an interval (J) between polygons or circles are set in advance, scanning is performed along a path in a set step length (B) from a start point coordinate (Xs, ys) of each path, when a point (Xt, yt) is scanned on the path, if Xt-Xs is not less than C (polygon long side length), the path is cut at a scanning point coordinate (Xt, yt), the scanned path is deleted, then a polygon or a circle is created between the start point coordinate (Xs, ys) and the scanning point coordinate (Xt, yt) according to the set long side length (C) and narrow side length (D), and after the creation is completed, setting new start point coordinates (Xs, ys) as the previous scanning point coordinates (Xt, yt) to continue scanning along the path by the step length B, cutting off the path and deleting the scanned path at the scanning point coordinates (Xt, yt) when scanning the point (Xt, yt) on the path, if Xt-Xs is larger than or equal to J (interval value), setting the start point coordinates (Xs, ys) as the coordinates (Xt, yt) of the scanning point again, then scanning and comparing calculation to the next point on the path by the set step length B, and creating a polygon or circle at the corresponding position according to the above condition until the scanning point coordinates (Xt, yt) are larger than the end point coordinates (Xe, ye).

And 7, storing the related data of the polygon or the circle created in the step 6 into a machine language file according to different process routes. The specific process route comprises a knife-engraving process, a photoetching process and an etching process, and the related machine languages comprise a G code (G-code) and an HP-GL code.

And 8, generating hollow polygons (2) or hollow circles (1) with intervals (3) on a base material by matching the file generated in the step 7 with a corresponding carving process, a photoetching process or an etching process, wherein the specific base material comprises paper, plastics and leather.
