Method and apparatus for determining sportsman jumps using fuzzy logic

摘要

A method and apparatus for detecting a jump of a moving sportsman and separating the jump from other sportsman motion is described. Accelerometer data generated by a sportsman's motion is received in a computing device. The computing device is used to apply fuzzy logic membership functions to a plurality of parameters associated with the accelerometer data to detect a pattern associated with jumps. A subset of the data is identified as representing a jump based upon the detection of the pattern. The determination is used in the computing device to transform data, whereby jumps are separated from other sportsman motion.

1. A method comprising:
receiving, by a computing device, accelerometer data generated by a sportsman's motion from an accelerometer coupled to the sportsman and in communication with the computing device; applying, by the computing device, a plurality of fuzzy logic membership functions to a plurality of parameters associated with the accelerometer data to detect a pattern associated with a jump, wherein detection of the pattern associated with the jump includes:
determining a fuzzy logic initial jump probability membership function;determining a fuzzy logic jump start probability membership function;determining a fuzzy logic landing shock probability membership function;determining a fuzzy logic false jump probability membership function; andcombining the jump start probability and landing shock probability membership functions together using fuzzy logic rules; identifying a subset of the accelerometer data representing the jump based upon the detected pattern; and transforming the accelerometer data, by the computing device, by separating the identified subset of accelerometer data representing the jump from accelerometer data associated with other motion by the sportsman.
