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. 6）, 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
Point 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, until reading
Stop reading to the right when the color value Y0-Y taken absolute value 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, as effectively successively on mutually search
Seek, occur stopping searching during inactive line, record the line number H1 of maximum effectively row；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, 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.
Workpiece direction of rotation is necessary for direction N shown in Fig. 3 in this implementation of class, to ensure knife that visual identity unit can obtain
The point of a knife part for having image is obscured.
Disclosed above is only preferred embodiment of the present utility model, but the utility model is not limited to this, any
