Depth be compared with the default depth that prestores, and adjusted according to the books page number of comparative result and the current setting
The coordinate data of the identification mark is specifically included：
Calculate the difference between spine depth in a groove and the default depth prestored；
Recognize the parity of the books page number of the current setting；
If the books page number of the current setting is even number, the identification mark exported using the coordinate positioning
Coordinate data adds the difference, to obtain the coordinate data after the identification mark adjustment；If the books of the current setting
The page number is odd number, then the coordinate data of the identification mark exported using the coordinate positioning subtracts the difference, with
Obtain the coordinate data after the identification mark adjustment.
8. the method for correcting coordinate of the point reader as described in claim any one of 5-7, it is characterised in that the identification mark bag
Include word, numeral or picture.
