Fig. 3 is the coded markings schematic diagram of dot matrix provided in an embodiment of the present invention coding.Medium in the present invention be with
Writing paper, blank, electronic display of dot matrix coding pattern etc..Dot matrix encodes the position that can determine digital pen input information.
As shown in figure 3, apply on medium it is position encoded be made of coded markings 32, according to the label relative to default
Position 33 or the position of optical grating point, the label can have there are four different value 0-3.As shown in figure 3, each symbol is circular point shape,
And along one of four different directions relative to 33 shift length 34 of predeterminated position.Predeterminated position 33 is located at visible or invisible
Or the point of intersection between the grid stroke 31 in Fictitious data base or grid.It is determined by the direction of displacement by the value of symbolic coding.Each
Symbol 0-3 can be converted into a position for being encoded to X-coordinate and another position for being encoded to Y coordinate, that is, be converted
At coordinate (0,0), (0,1), (1,0) and (1,1).Therefore, it can individually be encoded with Y-direction in X direction, but using X
Position and Y identical coded markings codings.
Optionally, distance 34 is not less than about the 1/8 of the distance between two adjacent grid strokes 31 and no more than big
About 1/4, preferably about 1/6.Each position is encoded with 6X6 coded markings, which can be converted into for the position
The 6X6 bit matrix of the 6X6 bit matrix for the x coordinate set and the Y coordinate for the position.If it is considered that x bit matrix, then the matrix can
It is divided into six row, six positions of each column.Each bit sequence by row constitutes a partial order in the main Number Sequence of cycle of 63 bit lengths
Row, the main Number Sequence have with properties, i.e., if selecting length for the partial sequence of 6 positions, the partial sequence is in the master
There is the position being unambiguously specified in Number Sequence.Therefore, six row are converted into six positional numbers or sequential value, correspond to master
Six positions in Number Sequence.Between this six positional numbers, in adjacent five differences of internal formation, it is poor that these differences are constituted
The partial sequence of Number Sequence, and therefore there is the position being unambiguously specified in the difference sequence, therefore there is quilt along x-axis
Clearly determining position.For specific x coordinate, positional number will change according to Y coordinate.On the other hand, difference is sat identical with Y
Mark it is unrelated because positional number always changes according to main Number Sequence, and the main Number Sequence in entire position encoded pattern in row
Circulating repetition.
Therefore, six rows in Y bit matrix define six positional numbers in main Number Sequence.This six positional numbers define
Five differences, the difference constitute the partial sequence of difference sequence and have the position being unambiguously specified along Y-axis.
Fig. 4 is dot matrix coding schematic diagram provided in an embodiment of the present invention.Grid stroke is shown in FIG. 4 merely to explanation.
In general, grating is virtual.When using digital pen in position code, digital pen is by the figure of the different piece of catch position code
Picture.Image may include far more than 6X6 symbol.Therefore, if a greater amount of data in the image as it can be seen that if can be based on 6X6
The different sets of a symbol are decoded position code.Surrounding symbol especially can be additionally used in decoding so as to carry out error-detecting and/
Or correction.
It should be noted, however, that even if the greater amount of symbol that the decoding that the visual field of digital pen includes position needs really, quilt
The quantity of useful coded markings in the image of record is also due to image fault and much less.
The coded markings of predetermined quantity, herein be 6X6 coded markings any arbitrary portion region will define a position
It sets, and at least some of arbitrary portion region coded markings contribute to the coding of an extra position.Unless in addition saying
It is bright, else if the arbitrary portion region upwards, downwards, be moved to the left or right the distances of a coded markings, move in this way
Arbitrary portion region in coded markings will define a new position.It is position encoded can to it is larger numbers of it is unique absolutely
Position is encoded.The position can be considered jointly defining huge virtual plane.The position being encoded on medium be
Position on this virtual plane, and the origin of position coordinates is the origin of virtual coordinates.Virtual plane or whole position codes
The different size of page can be logically partitioned into.Know any part such as digital pen or computer of the subdivision of virtual plane
Therefore can will be converted into from the virtual plane of medium recording position in the instruction and the page of the corresponding page one
Local location.
Medium provided in an embodiment of the present invention for dot matrix identification is write using image collecting device on medium
While acquisition dot matrix coded image be sent to terminal device, the area after terminal device is decoded where identification location information
Domain is handled accordingly according to the region where location information, to realize handwriting personalization storage and display.
