¿µ¹®³»¿ë¿ä¾à | In the previous standard TTAK.KO-10.0932, S2-PSK is provided and only support the scenario when 2 LEDs are in the same row in captured image. In the standard, 2 additional decoding methods are added to support sampling time deviation phenomenon caused by rolling shutter camera. They are cross-check-XOR and temporal-XOR decoding method.
In the new standard, the sampling time deviation phenomenon, caused by rolling shutter camera, is defined. The main functions and two new decoding methods of S2-PSK are newly added with clear descriptions. |
