Described visual identity unit 7 is visual identity camera.
The present embodiment gives the visual identity method of the flat carving engraving machine, comprises the following steps:
Step 1):Visual identity unit gathers head bottommost to the distance on workpiece incision surface;
Step 2):Camera uses black and white camera, and the image of acquisition is stored as the gray-scale map of 8 256 ranks, the face of cutter The background colour of color and main shaft bottom, workpiece and cutter periphery has an obvious differentiation, and the color of cutter is silvery white in this implementation of class, Main shaft bottom, workpiece and the selection of cutter periphery background colour are black or grey, manually adjust the image that camera obtains Center is located on cutter, so as to obtain color value of the cutter in camera obtains image;
Step 3):Step 2)The gray-scale map of 8 256 ranks obtained is made up of two-dimensional image vegetarian refreshments, the color of each pixel by Color value determines that storage organization used is two bit arrays of positive shaping.
In the present embodiment, described step 3)In, the size of camera visual field is 800*600, and two-dimensional array used is A [800] [600], the value deposited in each array location are 0-255, H=400 initial first, L=300, read field of view center, point A The color value Y of [H] [L], pixel A [H] [L-1] color value Y0 is then read, as Y0-Y absolute value is less than default threshold Value &, continue to read A [H] [L-2] to the left taking color value, until the color value Y0-Y absolute value read stop when being more than & to Left reading, record the row coordinate L0 of current pixel point;Pixel A [H] [L+1] color value Y0 is read, it is exhausted such as Y0-Y & is less than to value, continues to read A [H] [L+2] color value to the right, until the color value Y0-Y read absolute value stops when being more than & Only read to the right, record the row coordinate L1 of current pixel point, if L1-L0 is more than the effective row of 5 this journeys;With same search side Judge whether A [H+1] is effective row in normal direction, it is such as effectively upper successively mutually to search, occur stopping searching during inactive line, record is maximum The line number H1 of effective row;Judge whether A [H-1] is effective row downwards, it is such as effectively lower successively mutually to search, occur stopping during inactive line Search, record the line number H0 of minimum effectively row;H1-H0+1 is cutter in the number of lines of pixels shared by visual field vertical direction.
In the present embodiment, described predetermined threshold value & is 20.
The technical program, head bottommost is collected to the distance on workpiece incision surface, such as Fig. 2 by visual identity unit Known cutter length L before shown incision, after cutter cuts workpiece, visual identity element keeps track gathers head bottommost to workpiece The distance b on surface is cut, cutter total length L, which subtracts b, can calculate lower knife depth a, and Z-direction feeding is adjusted according to lower knife depth a, The effect of fluctuations that reaches carving depth with workpiece surface fluctuations.
Wherein visual identity principle as shown in Figure 3 a and Figure 3 b shows, because the relative position of camera and cutter immobilizes, Position of the tool image in the visual field that camera obtains is relatively constant, and cutter is obtained in visual field vertical direction by colour recognition Shared number of lines of pixels, the overall length L of cutter can be obtained when not cutting, the head bottommost in cutting to workpiece cuts surface Distance b.
The concrete methods of realizing of colour recognition is as follows in the present embodiment, and camera uses black and white camera, the image of acquisition The gray-scale map of 8 256 ranks is stored as, the color of cutter has obvious area with the background colour of main shaft bottom, workpiece and cutter periphery Point, the color of cutter is silvery white in this implementation of class, and main shaft bottom, workpiece and the selection of cutter periphery background colour are black or ash Color, the center for manually adjusting the image that camera obtains are located on cutter, are obtained so as to obtain cutter in camera Color value in image, as shown in Figure 4.
The gray-scale map of 8 256 ranks obtained in the present embodiment, picture are made up of two-dimensional image vegetarian refreshments, the color of each pixel Determined by color value(Such as Fig. 5), storage organization used is two bit arrays of positive shaping, if the size of visual field is 800*600, institute Two-dimensional array is A [800] [600], and the value deposited in each array location is 0-255, H=400 initial first, L=300, Field of view center is read, point A [H] [L] color value Y, then reading pixel A [H] [L-1] color value Y0 are exhausted such as Y0-Y & is less than to value(& is predetermined threshold value, and 20 are set in embodiment), continue reading A [H] [L-2] to the left and take color value, until reading Stop reading to the left when the color value Y0-Y taken absolute value is more than &, record the row coordinate L0 of current pixel point;Read Pixel A [H] [L+1] color value Y0, as Y0-Y absolute value is less than &, continue to read A [H] [L+2] color value to the right, directly Stop reading to the right when being more than & to the color value Y0-Y of reading absolute value, the row coordinate L1 of current pixel point is recorded, if L1- L0 is more than the effective row of 5 this journeys.Judge whether A [H+1] is effective row upwards with same method for searching, on effectively successively Mutually search, occur stopping searching during inactive line, record the line number H1 of maximum effectively row;Judge whether A [H-1] is effective downwards OK, mutually searched as effectively lower successively, occur stopping searching during inactive line, record the line number H0 of minimum effectively row.H1-H0+1 is Cutter is in the number of lines of pixels shared by visual field vertical direction.
Middle cutter Y-direction direction of feed must be direction N shown in Fig. 6 in this implementation of class, to ensure that visual identity unit can obtain Tool image point of a knife part it is obscured.
Disclosed above is only preferred embodiment of the present utility model, but the utility model is not limited to this, any What those skilled in the art can think does not have creative change, and is made under the premise of the utility model principle is not departed from Some improvements and modifications, should all fall in the scope of protection of the utility model.
