The specific embodiment
In order to solve current dependence manual mode, carve picture inefficiency, problem that accuracy is lower, present embodiment provides a kind of preparation method and device thereof of density board carving picture.Below in conjunction with specific embodiment, the preparation method of density board carving picture and device thereof are specifically described.
Please refer to Fig. 1, the preparation method of the density board carving picture that present embodiment provides, comprises the steps:
Step S110: apply one deck colouring discrimination in the material of described density board color on the surface of density board.In this step, can select black density plate for carving picture.Then on this black density plate, need to apply one deck colouring discrimination in the material of density board, the color of this coating material is not black, certainly preferably can form the comparatively obviously color of contrast with black, the follow-up like this picture carving out has more obvious third dimension.In the present embodiment, coating material be colouring discrimination in the paint of density board color, further, this paint can be selected environment protection oil paint.In order to make engraving effect better, one deck paint applying on density board surface should even thickness.
Step S120: analyze picture to be carved, determine the machined parameters of numerical controlled engraving and milling device.In this step, can adopt the machined parameters of special software analysis picture to be carved definite numerical controlled engraving and milling device.This special software first obtains picture to be carved, then analyzes the shade of each pixel on this picture to be carved, according to shade, can determine that this pixel correspondence needs the degree of depth of processing in density board.In brief, the color depth that is exactly certain pixel is larger, and it is also just darker that this pixel correspondence needs the degree of depth of processing in density board so, is that carving depth can solid represent image content like this by picture color corresponding conversion.In the present embodiment, working depth is to be determined by the shade of picture to be carved, and actually adds man-hour, and working depth is that rotating speed and the feed speed of numerical controlled engraving and milling device determines.Therefore first need to determine with the shade of picture to be carved rotating speed and the feed speed of numerical controlled engraving and milling device.Please refer to Fig. 2, according to the shade of picture to be carved, determine that the rotating speed of numerical controlled engraving and milling device and the step of feed speed comprise:
Step S210: set maximum depth value.According to the thickness of density board, a maximum depth value can be first set, maximum depth value is exactly the depth capacity that numerical controlled engraving and milling device can be worked in density board.This maximum depth value should be less than the thickness of density board in theory, avoids the situation that occurs hollow out density board to occur.
Step S220: obtain pixel value corresponding to each pixel on picture to be carved.In this step, adopt exactly special software to obtain pixel value corresponding to each pixel on picture to be carved.
Step S230: be depth coefficient by each pixel value corresponding conversion.The number range of depth coefficient is 0～1.
Step S240: depth coefficient corresponding to all pixel values is multiplied by described maximum depth value, obtains the working depth (in Fig. 4, working depth is represented by a) of each pixel correspondence in density board.Because the number range of depth coefficient is 0～1, therefore, depth coefficient corresponding to all pixel values is multiplied by the working depth that maximum depth value obtains and is just limited in maximum depth value with interior.
Step S250: rotating speed and the feed speed of determining numerical controlled engraving and milling device according to described working depth.The degree of depth that need to process according to each pixel value, rotating speed and the feed speed of numerical controlled engraving and milling device while determining each pixel value of processing.Such as when the darker pixel value of a certain color of processing, corresponding working depth is just darker, and now the rotating speed of definite numerical controlled engraving and milling device and feed speed just should be larger, and certain concrete rotating speed and feed speed is to be determined by concrete working depth.
In addition,, in step S120, machined parameters also comprises path internal, machining angle.Incorporated by reference to Fig. 3, numerical controlled engraving and milling device, when processing density board, take processing mode processing line by line, and path internal (in Fig. 3, path internal is represented by b) is exactly for determining the parameter of the distance between adjacent two row.Be understandable that, path internal is less, and the image carving out is finer and smoother, but workload is also larger; Path internal is less, and workload is less, but the image effect carving out is poorer.Therefore, should select according to actual needs moderate path internal.Machining angle (in Fig. 3, machining angle is represented by c) refers to and adds line by line man-hour, the angle of every a line and density board side, and this angle can be any one angle in 0～180 degree.In addition, machined parameters also comprises working width (in Fig. 3, working width is represented by d), and working width refers to the width of every a line processing.
Step S130: the processing cutter track that generates numerical controlled engraving and milling device according to described machined parameters.In this step, according to machined parameters definite in step S120, can generate the processing cutter track of numerical controlled engraving and milling device.
Step S140: constant density plate, according to the processing cutter track of described numerical controlled engraving and milling device, density board is carved.In this step, according to the processing cutter track of numerical controlled engraving and milling device, the graver of numerical controlled engraving and milling device can process each pixel on picture to be carved in density board.
In addition, in the present embodiment, before step S110, also comprise the steps:
Step S100: the size of determining density board according to picture to be carved.Because the size of picture to be carved differs, therefore need to determine according to picture to be carved the size of density board.In order to avoid use and cause waste compared with large density board compared with little picture, or cannot complete engraving compared with large picture because of the density board of selection of small.
After step S140, also comprise the steps:
Step S150: the density board that completes engraving is cleared up.In the density board of just having carved, may contain some wood chip fragments, in order clearly to represent carved image, after completing engraving, also need density board to clean out.
The preparation method of above-mentioned density board carving picture, the picture analyzing result of numerical controlled engraving and milling device based on to be carved generates processing cutter track automatically, according to this processing cutter track, can complete the engraving to density board.And the surface of density board applies one deck colouring discrimination in the material of described density board color, complete after engraving, the part of the carved rejecting of density board presents the color of density board itself, and not carved part presents the color of coating material, thereby formation two tone image, has obvious stereoeffect.The step that the preparation method of above-mentioned density board carving picture completes engraving is completed automatically by numerical controlled engraving and milling device, therefore has higher efficiency and accuracy.
A kind of producing device of density board carving picture is also provided in addition.Please refer to Fig. 5, the producing device 300 of the density board carving picture that present embodiment provides comprises processor 310 and numerical controlled engraving and milling device 320.Processor 310 is connected in numerical controlled engraving and milling device 320.
