Step 2: calculating from INT (N/2)+1 before the y-axis of single matrix-block when N is odd number and waiting hornblocks corresponding The length on the side parallel with x-axis, and calculate the numerical value of their any combination addition, i.e., correspond to the equal hornblocks that any combination is added The length that the side parallel with x-axis is added when tinting, i.e., corresponding a unique binary code k, N-INT (N/2) -1 after calculating The length on the corresponding side parallel with y-axis of hornblocks is waited, and calculates the numerical value of their any combination addition, corresponds to binary code L, k and l combine to form binary code a；

Step 4:, according to hornblocks such as the N parts delimited in advance, identifying that the sensor of equipment detects single matrix when N is even number In block, the length on side parallel with x-axis in the corresponding painted portion of hornblocks is waited from first N/2 of the y-axis of single matrix-block With the length and their any combination on the length and the side parallel with x-axis corresponding with the preceding N/2 equal hornblocks are added Numerical value compared one by one, determine corresponding binary code I, identify that the sensor of equipment detects single matrix-block In, from latter N/2 of the y-axis of single matrix-block equal hornblock corresponding painted portion the length on the side parallel with y-axis and, The length on the corresponding side parallel with y-axis of hornblocks and their any combination is waited to be added by the length and with described latter N/2 Numerical value is compared one by one, then determines that described latter N/2 is waited corresponding binary code J, I and the J combination of hornblocks to constitute single two Ary codes a, then calculate the binary code of all equal hornblocks in matrix-block, a series of corresponding binary systems of combination producing multidimensional code Code；

Step 5:, according to hornblocks such as the N parts delimited in advance, identifying that the sensor of equipment detects single matrix when N is odd number In block, side parallel with x-axis in the corresponding painted portion of hornblocks is waited from preceding INT (N/2)+1 of the y-axis of single matrix-block Length and, by the length on the length and the side parallel with x-axis corresponding with the preceding INT (N/2)+1 equal hornblocks and it Any combination be added numerical value compared one by one, determine corresponding binary code k, identify equipment sensor examine It measures in single matrix-block, waits the corresponding painted portion of hornblocks from rear N-INT (N/2) -1 of the y-axis of single matrix-block In the side parallel with y-axis length and, by the length and with it is described after N-INT (N/2) -1 equal hornblocks it is corresponding parallel with y-axis Side length and the numerical value that is added of their any combination compared determine described N-INT (N/2) -1 etc. afterwards again one by one Corresponding binary code l, k and the l combination of hornblock constitutes single binary code a, then calculates all single matrixes in matrix-block The binary code of block, a series of corresponding binary codes of combination producing multidimensional code.
