Title:
PHASE CORRECTION DEVICE, ACTION IDENTIFICATION DEVICE, ACTION IDENTIFICATION SYSTEM, MICROCONTROLLER, PHASE CORRECTION METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2016120271
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a phase correction device which can appropriately perform correction, and provide an action identification device, an action identification system, a microcontroller, a phase correction method and a program.SOLUTION: A phase correction device comprises: a standard deviation calculation part 162 to which a plurality of pieces of acceleration data are input and which calculates a standard deviation of the plurality of pieces of acceleration data for each prescribed time; an average value calculation part 164 to which the plurality of pieces of acceleration data are input and which calculates an average value of the acceleration data for each prescribed time; a phase estimation part 170 which estimates the phase of the average value in a space having a first coordinate axis and a second coordinate axis using the average value in the case where the standard deviation is smaller than a prescribed threshold; and a phase correction part 180 which performs phase correction on the average value by using the estimated phase.SELECTED DRAWING: Figure 16
