b. calculating a matching value: as shown in fig. 2, a side length ratio weight coefficient w1=0.5, an area ratio weight coefficient w2=0.5, a side length matching threshold T1=0.2, and an area matching threshold T2=0.2 are set; as shown, panel 1 is calculated: p =86.74%, panel 2: p =0%, panel 3=58.95%;
c. selecting a target screen matching drawing board: as shown in fig. 2, the matching degree values of the three drawing boards are 86.74% at the maximum and correspond to the drawing board 1;
d. the optimal drawing board is adapted to the target screen: as shown in fig. 2, the matching degree value 86.74% of the drawing board 1 is greater than the matching degree threshold K (60%), so the drawing board 1 is the best matching drawing board.
1 in the above edge length values refers to a pixel point in the drawing board, and refers to an LED lamp bead in the LED target screen.
Compared with the prior art, the method for matching the rectangular screen (including the square screen) with the multiple drawing boards in the LED program has the following advantages:
