Point, the color of cutter is silvery white in this implementation of class, and main shaft bottom, workpiece and cutter periphery background colour are selected as black or ash
Color, the center for manually adjusting the image that photographic head is obtained is located on cutter, is obtained in photographic head so as to obtain cutter
Color value in image, as shown in Figure 5.
The gray-scale maps of 8 256 ranks obtained in the present embodiment, picture is made up of two-dimensional image vegetarian refreshments, the color of each pixel
Determined by color value（Such as Fig. 6）, storage organization used is two bit arrays of positive shaping, such as the size of visual field be 800*600, institute
Two-dimensional array is A [800] [600], in each array location deposit value be 0-255, initial first H=400, L=300,
Read field of view center, color value Y of point A [H] [L], then color value Y0 of read pixel point A [H] [L-1], such as Y0-Y's is exhausted
＆ 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 absolute value of color value Y0-Y for taking is more than ＆, record the row coordinate L0 of current pixel point；Read pixel
Color value Y0 of point A [H] [L+1], the such as absolute value of Y0-Y are less than ＆, continue to read A [H] [L+2] color value to the right, until reading
Stop reading to the right when the absolute value of color value Y0-Y for taking is more than ＆, the row coordinate L1 of current pixel point is recorded, if L1-L0 is big
In the effective row of 5 this journeys.Judge whether A [H+1] is effective row upwards with same method for searching, such as effectively go up successively and mutually search
Seek, occur stopping searching during inactive line, line number H1 of the maximum effectively row of record；Judge whether A [H-1] is effective row downwards, such as
It is effectively lower successively mutually to search, occur stopping searching during inactive line, line number H0 of the minimum effectively row of record.H1-H0+1 is cutter
In the number of lines of pixels shared by the vertical direction of visual field.
Workpiece direction of rotation is necessary for direction N shown in Fig. 3 to ensure the knife that visual identity unit can be obtained in this implementation of class
The point of a knife part of tool image is obscured.
Disclosed above is only the preferred embodiment of the present invention, but the present invention is not limited to this, any this area
What technical staff can think does not have a creative change, and some improvement made without departing from the principles of the present invention and
Retouching, all should be within the scope of the present invention.
